+- Lessons: [Sprint 4 - Plugin Commands Implementation](https://gitea.hotserv.cloud/personal-projects/leo-claude-mktplace/wiki/lessons/sprints/sprint-4---plugin-commands-implementation)
+
+### Fixed
+- **MCP:** Project directory detection - all run.sh scripts now capture `CLAUDE_PROJECT_DIR` from PWD before changing directories
+- **Docs:** Added Gitea auto-close behavior and MCP session restart notes to DEBUGGING-CHECKLIST.md
+
+---
+
+#### Sprint 3: Hooks (V5.2.0 Plugin Enhancements)
+Implementation of 6 foundational hooks across 4 plugins.
+
+**git-flow v1.1.0:**
+- **Commit message enforcement hook** - PreToolUse hook validates conventional commit format on all `git commit` commands (not just `/commit`). Blocks invalid commits with format guidance.
+- **Branch name validation hook** - PreToolUse hook validates branch naming on `git checkout -b` and `git switch -c`. Enforces `type/description` format, lowercase, max 50 chars.
+
+**clarity-assist v1.1.0:**
+- **Vagueness detection hook** - UserPromptSubmit hook detects vague prompts and suggests `/clarify` when ambiguity, missing context, or unclear scope detected.
+
+**data-platform v1.1.0:**
+- **Schema diff detection hook** - PostToolUse hook monitors edits to schema files (dbt models, SQL migrations). Warns on breaking changes (column removal, type narrowing, constraint addition).
+
+**contract-validator v1.1.0:**
+- **SessionStart auto-validate hook** - Smart validation that only runs when plugin files changed since last check. Detects interface compatibility issues at session start.
+- **Breaking change detection hook** - PostToolUse hook monitors plugin interface files (README.md, plugin.json). Warns when changes would break consumers.
+
+**Sprint Completed:**
+- Milestone: Sprint 3 - Hooks (closed 2026-01-28)
+- Issues: #225, #226, #227, #228, #229, #230
+- Wiki: [Change V5.2.0: Plugin Enhancements Proposal](https://gitea.hotserv.cloud/personal-projects/leo-claude-mktplace/wiki/Change-V5.2.0:-Plugin-Enhancements-Proposal)
+- Lessons: Background agent permissions, agent runaway detection, MCP branch detection bug
+
+### Known Issues
+- **MCP Bug #231:** Branch detection in Gitea MCP runs from installed plugin directory, not user's project directory. Workaround: close issues via Gitea web UI.
+
+---
+
+#### Gitea MCP Server - create_pull_request Tool
+- **`create_pull_request`**: Create new pull requests via MCP
+  - Parameters: title, body, head (source branch), base (target branch), labels
+  - Branch-aware security: only allowed on development/feature branches
+  - Completes the PR lifecycle (was previously missing - only had list/get/review/comment)
+
+#### cmdb-assistant v1.1.0 - Data Quality Validation
+- **SessionStart Hook**: Tests NetBox API connectivity at session start
+  - Warns if VMs exist without site assignment
+  - Warns if devices exist without platform
+  - Non-blocking: displays warning, doesn't prevent work
+- **PreToolUse Hook**: Validates input parameters before VM/device operations
+  - Warns about missing site, tenant, platform
+  - Non-blocking: suggests best practices without blocking
+- **`/cmdb-audit` Command**: Comprehensive data quality analysis
+  - Scopes: all, vms, devices, naming, roles
+  - Identifies Critical/High/Medium/Low issues
+  - Provides prioritized remediation recommendations
+- **`/cmdb-register` Command**: Register current machine into NetBox
+  - Discovers system info: hostname, platform, hardware, network interfaces
+  - Discovers running apps: Docker containers, systemd services
+  - Creates device with interfaces, IPs, and sets primary IP
+  - Creates cluster and VMs for Docker containers
+- **`/cmdb-sync` Command**: Sync machine state with NetBox
+  - Compares current state with NetBox record
+  - Shows diff of changes (interfaces, IPs, containers)
+  - Updates with user confirmation
+  - Supports --full and --dry-run flags
+- **NetBox Best Practices Skill**: Reference documentation
+  - Dependency order for object creation
+  - Naming conventions (`{role}-{site}-{number}`, `{env}-{app}-{number}`)
+  - Role consolidation guidance
+  - Site/tenant/platform assignment requirements
+- **Agent Enhancement**: Updated cmdb-assistant agent with validation requirements
+  - Proactive suggestions for missing fields
+  - Naming convention checks
+  - Dependency order enforcement
+  - Duplicate prevention

+
+### Gitea Auto-Close Behavior
+
+**Issue:** Using `Closes #XX` or `Fixes #XX` in commit/PR messages does NOT auto-close issues when merging to `development`.
+
+**Root Cause:** Gitea only auto-closes issues when merging to the **default branch** (typically `main` or `master`). Merging to `development`, `staging`, or any other branch will NOT trigger auto-close.
+
+**Workaround:**
+1. Use the Gitea MCP tool to manually close issues after merging to development:
+   ```
+   mcp__plugin_projman_gitea__update_issue(issue_number=XX, state="closed")
+   ```
+2. Or close issues via the Gitea web UI
+3. The auto-close keywords will still work when the changes are eventually merged to `main`
+
+**Recommendation:** Include the `Closes #XX` keywords in commits anyway - they'll work when the final merge to `main` happens.
+
+### MCP Session Restart Requirement
+
+**Issue:** Changes to MCP servers, hooks, or plugin configuration don't take effect immediately.
+
+**Root Cause:** Claude Code loads MCP tools and plugin configuration at session start. These are cached in session memory and not reloaded dynamically.
+
+**What requires a session restart:**
+- MCP server code changes (Python files in `mcp-servers/`)
+- Changes to `.mcp.json` files
+- Changes to `hooks/hooks.json`
+- Changes to `plugin.json`
+- Adding new MCP tools or modifying tool signatures
+
+**What does NOT require a restart:**
+- Command/skill markdown files (`.md`) - these are read on invocation
+- Agent markdown files - read when agent is invoked
+
+**Correct workflow after plugin changes:**
+1. Make changes to source files
+2. Run `./scripts/verify-hooks.sh` to validate
+3. Inform user: "Please restart Claude Code for changes to take effect"
+4. **Do NOT clear cache mid-session** - see "Cache Clearing" section

+# viz-platform MCP Server
+
+Model Context Protocol (MCP) server for Dash Mantine Components validation and visualization tools.
+
+## Overview
+
+This MCP server provides 21 tools for:
+- **DMC Validation**: Version-locked component registry prevents Claude from hallucinating invalid props
+- **Chart Creation**: Plotly-based visualization with theme integration
+- **Layout Composition**: Dashboard layouts with responsive grids
+- **Theme Management**: Design token-based theming system
+- **Page Structure**: Multi-page Dash app generation
+
+## Tools
+
+### DMC Tools (3)
+
+| Tool | Description |
+|------|-------------|
+| `list_components` | List available DMC components by category |
+| `get_component_props` | Get valid props, types, and defaults for a component |
+| `validate_component` | Validate component definition before use |
+
+### Chart Tools (2)
+
+| Tool | Description |
+|------|-------------|
+| `chart_create` | Create Plotly chart (line, bar, scatter, pie, histogram, area, heatmap) |
+| `chart_configure_interaction` | Configure chart interactions (zoom, pan, hover) |
+
+### Layout Tools (5)
+
+| Tool | Description |
+|------|-------------|
+| `layout_create` | Create dashboard layout structure |
+| `layout_add_filter` | Add filter components to layout |
+| `layout_set_grid` | Configure responsive grid settings |
+| `layout_get` | Retrieve layout configuration |
+| `layout_add_section` | Add sections to layout |
+
+### Theme Tools (6)
+
+| Tool | Description |
+|------|-------------|
+| `theme_create` | Create new theme with design tokens |
+| `theme_extend` | Extend existing theme with overrides |
+| `theme_validate` | Validate theme completeness |
+| `theme_export_css` | Export theme as CSS custom properties |
+| `theme_list` | List available themes |
+| `theme_activate` | Set active theme for visualizations |
+
+### Page Tools (5)
+
+| Tool | Description |
+|------|-------------|
+| `page_create` | Create new page structure |
+| `page_add_navbar` | Add navigation bar to page |
+| `page_set_auth` | Configure page authentication |
+| `page_list` | List available pages |
+| `page_get_app_config` | Get full app configuration |
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Required | Description |
+|----------|----------|-------------|
+| `DMC_VERSION` | No | Dash Mantine Components version (auto-detected if installed) |
+| `VIZ_DEFAULT_THEME` | No | Default theme name |
+| `CLAUDE_PROJECT_DIR` | No | Project directory for theme storage |
+
+### Theme Storage
+
+Themes can be stored at two levels:
+- **User-level**: `~/.config/claude/themes/`
+- **Project-level**: `{project}/.viz-platform/themes/`
+
+Project-level themes take precedence.
+
+## Component Registry
+
+The server uses a static JSON registry for DMC component validation:
+- Pre-generated from DMC source code
+- Version-tagged (e.g., `dmc_2_5.json`)
+- Prevents hallucination of non-existent props
+- Fast, deterministic validation
+
+Registry files are stored in `registry/` directory.
+
+## Tests
+
+94 tests with coverage:
+- `test_config.py`: 82% coverage
+- `test_component_registry.py`: 92% coverage
+- `test_dmc_tools.py`: 88% coverage
+- `test_chart_tools.py`: 68% coverage
+- `test_theme_tools.py`: 99% coverage
+
+Run tests:
+```bash
+cd mcp-servers/viz-platform
+source .venv/bin/activate
+pytest tests/ -v
+```
+
+## Dependencies
+
+- Python 3.10+
+- FastMCP
+- plotly
+- dash-mantine-components (optional, for version detection)
+
+## Usage
+
+This MCP server is used by the `viz-platform` plugin. See [plugins/viz-platform/README.md](../../plugins/viz-platform/README.md) for usage instructions.

+# Neurodivergent Support in clarity-assist
+
+This document describes how clarity-assist is designed to support users with neurodivergent traits, including ADHD, autism, anxiety, and other conditions that affect executive function, sensory processing, or cognitive style.
+
+## Overview
+
+### Purpose
+
+clarity-assist exists to help all users transform vague or incomplete requests into clear, actionable specifications. For neurodivergent users specifically, it addresses common challenges:
+
+- **Executive function difficulties** - Breaking down complex tasks, getting started, managing scope
+- **Working memory limitations** - Keeping track of context across long conversations
+- **Decision fatigue** - Facing too many open-ended choices
+- **Processing style differences** - Preferring structured, predictable interactions
+- **Anxiety around uncertainty** - Needing clear expectations and explicit confirmation
+
+### Philosophy
+
+Our design philosophy centers on three principles:
+
+1. **Reduce cognitive load** - Never force the user to hold too much in their head at once
+2. **Provide structure** - Use consistent, predictable patterns for all interactions
+3. **Respect different communication styles** - Accommodate rather than assume one "right" way to think
+
+## Features for ND Users
+
+### 1. Reduced Cognitive Load
+
+**Prompt Simplification**
+- The 4-D methodology (Deconstruct, Diagnose, Develop, Deliver) breaks down complex requests into manageable phases
+- Users never need to specify everything upfront - clarification happens incrementally
+
+**Task Breakdown**
+- Large requests are decomposed into explicit components
+- Dependencies and relationships are surfaced rather than left implicit
+- Scope boundaries are clearly defined (in-scope vs. out-of-scope)
+
+### 2. Structured Output
+
+**Consistent Formatting**
+- Every clarification session produces the same structured specification:
+  - Summary (1-2 sentences)
+  - Scope (In/Out)
+  - Requirements table (numbered, prioritized)
+  - Assumptions list
+- This predictability reduces the mental effort of parsing responses
+
+**Predictable Patterns**
+- Questions always follow the same format
+- Progress summaries appear at regular intervals
+- Escalation (simple to complex) is always offered, never forced
+
+**Bulleted Lists Over Prose**
+- Requirements are presented as scannable lists, not paragraphs
+- Options are numbered for easy reference
+- Key information is highlighted with bold labels
+
+### 3. Customizable Verbosity
+
+**Detail Levels**
+- `/clarify` - Full methodology for complex requests (more thorough, more questions)
+- `/quick-clarify` - Rapid mode for simple disambiguation (fewer questions, faster)
+
+**User Control**
+- Users can always say "that's enough detail" to end questioning early
+- The plugin offers to break sessions into smaller parts
+- "Good enough for now" is explicitly validated as an acceptable outcome
+
+### 4. Vagueness Detection
+
+The `UserPromptSubmit` hook automatically detects prompts that might benefit from clarification and gently suggests using `/clarify`.
+
+**Detection Signals**
+- Short prompts (< 10 words) without specific technical terms
+- Vague action phrases: "help me", "fix this", "make it better"
+- Ambiguous scope words: "somehow", "something", "stuff", "etc."
+- Open questions without context
+
+**Non-Blocking Approach**
+- The hook never prevents you from proceeding
+- It provides a suggestion with a vagueness score (percentage)
+- You can disable auto-suggestions entirely via environment variable
+
+### 5. Focus Aids
+
+**Task Prioritization**
+- Requirements are tagged as Must/Should/Could/Won't (MoSCoW)
+- Critical items are separated from nice-to-haves
+- Scope creep is explicitly called out and deferred
+
+**Context Switching Warnings**
+- When questions touch multiple areas, the plugin acknowledges the complexity
+- Offers to focus on one aspect at a time
+- Summarizes frequently to rebuild context after interruptions
+
+## How It Works
+
+### The UserPromptSubmit Hook
+
+When you submit a prompt, the vagueness detection hook (`hooks/vagueness-check.sh`) runs automatically:
+
+```
+User submits prompt
+       |
+       v
+Hook reads prompt from stdin
+       |
+       v
+Skip if: empty, starts with /, or contains file paths
+       |
+       v
+Calculate vagueness score (0.0 - 1.0)
+  - Short prompts: +0.3
+  - Vague action phrases: +0.2
+  - Ambiguous scope words: +0.15
+  - Missing technical specifics: +0.2
+  - Short questions without context: +0.15
+       |
+       v
+If score >= threshold (default 0.6):
+  - Output gentle suggestion with [clarity-assist] prefix
+  - Show vagueness percentage
+       |
+       v
+Exit 0 (always non-blocking)
+```
+
+### Example Hook Output
+
+```
+[clarity-assist] Your prompt could benefit from more clarity.
+[clarity-assist] Consider running /clarity-assist to refine your request.
+[clarity-assist] (Vagueness score: 65% - this is a suggestion, not a block)
+```
+
+### The 4-D Methodology
+
+| Phase | What Happens | ND Benefit |
+|-------|--------------|------------|
+| **Deconstruct** | Break request into components | Shows the full picture without overwhelming |
+| **Diagnose** | Identify gaps and conflicts | Surfaces hidden assumptions |
+| **Develop** | Ask structured questions | Option-based, chunked, contextual |
+| **Deliver** | Produce specification | Consistent, scannable format |
+
+## Usage Examples
+
+### Before: Vague Request
+
+```
+User: Make the app faster
+```
+
+This triggers vagueness detection because:
+- Short (4 words)
+- Vague action ("make")
+- No specific technical context
+- No measurable outcome
+
+### After: Clarified with /clarify
+
+```
+User: /clarify Make the app faster
+
+Claude: Let me help clarify what kind of performance improvements you're looking for.
+
+**What type of slowness are you experiencing?**
+1. Initial page load takes too long
+2. Interactions feel sluggish (clicking, typing)
+3. API calls are slow
+4. All of the above
+5. Other
+
+[I'm asking because each has very different solutions]
+```
+
+```
+User: 1
+
+Claude: Initial page load - got it.
+
+**What's an acceptable load time for you?**
+1. Under 1 second (aggressive)
+2. Under 2 seconds (standard)
+3. Under 3 seconds (relaxed)
+4. I don't have a specific target
+
+[This helps me know whether to suggest quick wins or a major optimization effort]
+```
+
+After 2-3 more questions, the user receives:
+
+```markdown
+## Clarified Request
+
+### Summary
+Optimize initial page load time to under 2 seconds by addressing bundle size and initial render blocking resources.
+
+### Scope
+**In Scope:**
+- Bundle analysis and splitting
+- Lazy loading non-critical components
+- Image optimization
+- CSS/JS minification check
+
+**Out of Scope:**
+- Backend API optimization
+- Database query performance
+- CDN setup
+
+### Requirements
+| # | Requirement | Priority | Notes |
+|---|-------------|----------|-------|
+| 1 | Page loads in < 2s on 4G | Must | Measured via Lighthouse |
+| 2 | Largest contentful paint < 1.5s | Should | Core Web Vital |
+| 3 | No layout shift after load | Should | CLS < 0.1 |
+
+### Assumptions
+- Current load time is > 3 seconds (based on "too long" description)
+- Target browsers: modern evergreen (Chrome, Firefox, Safari)
+- Build tooling already configured (webpack/vite)
+```
+
+### Common Patterns Detected
+
+| Pattern | Example | What It Triggers |
+|---------|---------|------------------|
+| Missing context | "Fix the bug" | "Which bug? In which file or feature?" |
+| Ambiguous scope | "Update the user stuff" | "What specifically needs updating?" |
+| Unclear goals | "Make it better" | "Better in what way? Faster? Cleaner? More features?" |
+| Implicit knowledge | "Do it like last time" | "I don't have context from previous sessions" |
+| Conflicting requests | "Keep it simple but add everything" | "Which matters more: simplicity or completeness?" |
+
+### Quick-Clarify Example
+
+For simpler requests that just need minor disambiguation:
+
+```
+User: /quick-clarify Add a delete button to the user list
+
+Claude: I'll add a delete button to each row in the user list.
+
+**Should deletion require confirmation?**
+1. Yes - show confirmation dialog (Recommended)
+2. No - delete immediately
+3. Soft delete - mark as deleted but keep data
+
+[Asking because accidental deletions can be problematic]
+```
+
+```
+User: 1
+
+Claude: Got it. I'll implement a delete button with confirmation dialog. Starting now.
+```
+
+## Configuration Options
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CLARITY_ASSIST_AUTO_SUGGEST` | `true` | Enable/disable automatic vagueness detection |
+| `CLARITY_ASSIST_VAGUENESS_THRESHOLD` | `0.6` | Score threshold to trigger suggestion (0.0-1.0) |
+
+### Disabling Auto-Suggestions
+
+If you find the vagueness detection unhelpful, disable it in your shell profile or `.env`:
+
+```bash
+export CLARITY_ASSIST_AUTO_SUGGEST=false
+```
+
+### Adjusting Sensitivity
+
+To make detection more or less sensitive:
+
+```bash
+# More sensitive (suggests more often)
+export CLARITY_ASSIST_VAGUENESS_THRESHOLD=0.4
+
+# Less sensitive (only very vague prompts)
+export CLARITY_ASSIST_VAGUENESS_THRESHOLD=0.8
+```
+
+## Tips for ND Users
+
+### If You're Feeling Overwhelmed
+
+- Use `/quick-clarify` instead of `/clarify` for faster interactions
+- Say "let's focus on just one thing" to narrow scope
+- Ask to "pause and summarize" at any point
+- It's OK to say "I don't know" - the plugin will offer concrete alternatives
+
+### If You Have Executive Function Challenges
+
+- Start with `/clarify` even for tasks you think are simple - it helps with planning
+- The structured specification can serve as a checklist
+- Use the scope boundaries to prevent scope creep
+
+### If You Prefer Detailed Structure
+
+- The 4-D methodology provides a predictable framework
+- All output follows consistent formatting
+- Questions always offer numbered options
+
+### If You Have Anxiety About Getting It Right
+
+- The plugin validates "good enough for now" as acceptable
+- You can always revisit and change earlier answers
+- Assumptions are explicitly listed - nothing is hidden
+
+## Accessibility Notes
+
+- All output uses standard markdown that works with screen readers
+- No time pressure - take as long as you need between responses
+- Questions are designed to be answerable without deep context retrieval
+- Visual patterns (bold, bullets, tables) create scannable structure

+## Options
+
+| Option | Description |
+|--------|-------------|
+| `--commit=REF` | Compare working copy against specific commit/tag |
+| `--from=REF` | Starting point for comparison |
+| `--to=REF` | Ending point for comparison (default: HEAD) |
+| `--branch=NAME` | Compare against branch tip |
+| `--section=NAME` | Show only changes to specific section |
+| `--stat` | Show only statistics, no detailed diff |
+| `--no-color` | Disable colored output |
+| `--context=N` | Lines of context around changes (default: 3) |
+
+## Understanding the Output
+
+### Change Indicators
+
+| Symbol | Meaning |
+|--------|---------|
+| `+` | Line added |
+| `-` | Line removed |
+| `@@` | Location marker showing line numbers |
+| `[MODIFIED]` | Section has changes |
+| `[ADDED]` | New section created |
+| `[REMOVED]` | Section deleted |
+| `[UNCHANGED]` | No changes to section |
+
+### Impact Categories
+
+- **NEW REQUIREMENT** - Claude will now need to do something new
+- **REMOVED REQUIREMENT** - Claude no longer needs to do something
+- **MODIFIED** - Existing behavior changed
+- **NEW RULE** - New constraint added
+- **RELAXED RULE** - Constraint removed or softened
+
+## When to Use
+
+Run `/config-diff` when:
+- Before committing CLAUDE.md changes
+- Reviewing what changed after pulling updates
+- Debugging unexpected Claude behavior
+- Auditing configuration changes over time
+- Comparing configurations across branches
+
+## Integration with Other Commands
+
+| Workflow | Commands |
+|----------|----------|
+| Review before commit | `/config-diff` then `git commit` |
+| After optimization | `/config-optimize` then `/config-diff` |
+| Audit history | `/config-diff --from=v1.0.0 --to=HEAD` |
+| Branch comparison | `/config-diff --branch=main` |
+
+## Tips
+
+1. **Review before committing** - Always check what changed
+2. **Track behavioral changes** - Focus on rules and requirements sections
+3. **Use section filtering** - Large files benefit from focused diffs
+4. **Compare across releases** - Use tags to track major changes
+5. **Check after merges** - Ensure CLAUDE.md didn't get conflict artifacts
+
+## Troubleshooting
+
+### "No changes detected"
+- CLAUDE.md matches the comparison target
+- Check if you're comparing the right commits
+
+### "File not found in commit"
+- CLAUDE.md didn't exist at that commit
+- Use `git log -- CLAUDE.md` to find when it was created
+
+### "Not a git repository"
+- This command requires git history
+- Initialize git or use file backup comparison instead

+
+Available categories:
+- `security` - SEC rules
+- `structure` - STR rules
+- `content` - CNT rules
+- `format` - FMT rules
+- `bestpractice` - BPR rules
+
+## Custom Configuration
+
+Create `.claude-lint.json` in project root:
+
+```json
+{
+  "rules": {
+    "SEC001": "warning",
+    "FMT001": "off",
+    "CNT003": {
+      "severity": "warning",
+      "maxLines": 150
+    }
+  },
+  "ignore": [
+    "FMT*"
+  ],
+  "requiredSections": [
+    "Quick Start",
+    "Critical Rules",
+    "Project Overview"
+  ]
+}
+```
+
+## Anti-Pattern Examples
+
+### Hardcoded Secrets (SEC002)
+```markdown
+# BAD
+API_KEY=sk-1234567890abcdef
+
+# GOOD
+API_KEY=$OPENAI_API_KEY  # Set via environment
+```
+
+### Hardcoded Paths (SEC001)
+```markdown
+# BAD
+Config file: /home/john/projects/myapp/config.yml
+
+# GOOD
+Config file: ./config.yml
+Config file: $PROJECT_ROOT/config.yml
+```
+
+### Contradictory Rules (CNT001)
+```markdown
+# BAD
+- Always use TypeScript
+- JavaScript files are acceptable for scripts
+
+# GOOD
+- Always use TypeScript for source code
+- JavaScript (.js) is acceptable only for config files and scripts
+```
+
+### Vague Instructions (CNT002)
+```markdown
+# BAD
+- Be careful with the database
+
+# GOOD
+- Never run DELETE without WHERE clause
+- Always backup before migrations
+```
+
+### Invalid Hierarchy (STR002)
+```markdown
+# BAD
+# Main Title
+### Skipped Level
+
+# GOOD
+# Main Title
+## Section
+### Subsection
+```
+
+## When to Use
+
+Run `/config-lint` when:
+- Before committing CLAUDE.md changes
+- During code review for CLAUDE.md modifications
+- Setting up CI/CD checks for configuration files
+- After major edits to catch introduced issues
+- Periodically as maintenance check
+
+## Integration with CI/CD
+
+Add to your CI pipeline:
+
+```yaml
+# GitHub Actions example
+- name: Lint CLAUDE.md
+  run: claude /config-lint --strict --format=sarif > lint-results.sarif
+
+- name: Upload SARIF
+  uses: github/codeql-action/upload-sarif@v2
+  with:
+    sarif_file: lint-results.sarif
+```
+
+## Tips
+
+1. **Start with errors** - Fix errors before warnings

+
+## Data Quality Validation
+
+**IMPORTANT:** Load the `netbox-patterns` skill for best practice reference.
+
+Before ANY create or update operation, validate against NetBox best practices:
+
+### VM Operations
+
+**Required checks before `virt_create_vm` or `virt_update_vm`:**
+
+1. **Cluster/Site Assignment** - VMs must have either cluster or site
+2. **Tenant Assignment** - Recommend if not provided
+3. **Platform Assignment** - Recommend for OS tracking
+4. **Naming Convention** - Check against `{env}-{app}-{number}` pattern
+5. **Role Assignment** - Recommend appropriate role
+
+**If user provides no site/tenant, ASK:**
+
+> "This VM has no site or tenant assigned. NetBox best practices recommend:
+> - **Site**: For location-based queries and power budgeting
+> - **Tenant**: For resource isolation and ownership tracking
+>
+> Would you like me to:
+> 1. Assign to an existing site/tenant (list available)
+> 2. Create new site/tenant first
+> 3. Proceed without (not recommended for production use)"
+
+### Device Operations
+
+**Required checks before `dcim_create_device` or `dcim_update_device`:**
+
+1. **Site is REQUIRED** - Fail without it
+2. **Platform Assignment** - Recommend for OS tracking
+3. **Naming Convention** - Check against `{role}-{location}-{number}` pattern
+4. **Role Assignment** - Ensure appropriate role selected
+5. **After Creation** - Offer to set primary IP
+
+### Cluster Operations
+
+**Required checks before `virt_create_cluster`:**
+
+1. **Site Scope** - Recommend assigning to site
+2. **Cluster Type** - Ensure appropriate type selected
+3. **Device Association** - Recommend linking to host device
+
+### Role Management
+
+**Before creating a new device role:**
+
+1. List existing roles with `dcim_list_device_roles`
+2. Check if a more general role already exists
+3. Recommend role consolidation if >10 specific roles exist
+
+**Example guidance:**
+
+> "You're creating role 'nginx-web-server'. An existing 'web-server' role exists.
+> Consider using 'web-server' and tracking nginx via the platform field instead.
+> This reduces role fragmentation and improves maintainability."
+
+## Dependency Order Enforcement
+
+When creating multiple objects, follow this order:
+
+```
+1. Regions → Sites → Locations → Racks
+2. Tenant Groups → Tenants
+3. Manufacturers → Device Types
+4. Device Roles, Platforms
+5. Devices (with site, role, type)
+6. Clusters (with type, optional site)
+7. VMs (with cluster)
+8. Interfaces → IP Addresses → Primary IP assignment
+```
+
+**CRITICAL Rules:**
+- NEVER create a VM before its cluster exists
+- NEVER create a device before its site exists
+- NEVER create an interface before its device exists
+- NEVER create an IP before its interface exists (if assigning)
+
+## Naming Convention Enforcement
+
+When user provides a name, check against patterns:
+
+| Object Type | Pattern | Example |
+|-------------|---------|---------|
+| Device | `{role}-{site}-{number}` | `web-dc1-01` |
+| VM | `{env}-{app}-{number}` or `{prefix}_{service}` | `prod-api-01` |
+| Cluster | `{site}-{type}` | `dc1-vmware`, `home-docker` |
+| Prefix | Include purpose in description | "Production /24 for web tier" |
+
+**If name doesn't match patterns, warn:**
+
+> "The name 'HotServ' doesn't follow naming conventions.
+> Suggested: `prod-hotserv-01` or `hotserv-cloud-01`.
+> Consistent naming improves searchability and automation compatibility.
+> Proceed with original name? [Y/n]"
+
+## Duplicate Prevention
+
+Before creating objects, always check for existing duplicates:
+
+```
+# Before creating device
+dcim_list_devices name=<proposed-name>
+
+# Before creating VM
+virt_list_vms name=<proposed-name>
+
+# Before creating prefix
+ipam_list_prefixes prefix=<proposed-prefix>
+```
+
+If duplicate found, inform user and suggest update instead of create.

+
+# CMDB Change Audit
+
+Query and analyze the NetBox audit log for change tracking and compliance.
+
+## Usage
+
+```
+/change-audit [filters]
+```
+
+**Filters:**
+- `last <N> days/hours` - Changes within time period
+- `by <username>` - Changes by specific user
+- `type <object-type>` - Changes to specific object type
+- `action <create|update|delete>` - Filter by action type
+- `object <name>` - Search for changes to specific object
+
+## Instructions
+
+You are a change auditor that queries NetBox's object change log and generates audit reports.
+
+### MCP Tools
+
+Use these tools to query the audit log:
+
+- `extras_list_object_changes` - List changes with filters:
+  - `user_id` - Filter by user ID
+  - `changed_object_type` - Filter by object type (e.g., "dcim.device", "ipam.ipaddress")
+  - `action` - Filter by action: "create", "update", "delete"
+
+- `extras_get_object_change` - Get detailed change record by ID
+
+### Common Object Types
+
+| Category | Object Types |
+|----------|--------------|
+| DCIM | `dcim.device`, `dcim.interface`, `dcim.site`, `dcim.rack`, `dcim.cable` |
+| IPAM | `ipam.ipaddress`, `ipam.prefix`, `ipam.vlan`, `ipam.vrf` |
+| Virtualization | `virtualization.virtualmachine`, `virtualization.cluster` |
+| Tenancy | `tenancy.tenant`, `tenancy.contact` |
+
+### Workflow
+
+1. **Parse user request** to determine filters
+2. **Query object changes** using `extras_list_object_changes`
+3. **Enrich data** by fetching detailed records if needed
+4. **Analyze patterns** in the changes
+5. **Generate report** in structured format
+
+### Report Format
+

+2024-01-15: ████████ 8 changes
+2024-01-14: ████ 4 changes
+2024-01-13: ██ 2 changes
+```
+
+### Notable Patterns
+
+- **Bulk operations:** [Identify if many changes happened in short time]
+- **Unusual activity:** [Flag unexpected deletions or after-hours changes]
+- **Missing audit trail:** [Note if expected changes are not logged]
+
+### Recommendations
+
+1. [Any security or process recommendations based on findings]
+```
+
+### Time Period Handling
+
+When user specifies "last N days":
+- The NetBox API may not have direct date filtering in `extras_list_object_changes`
+- Fetch recent changes and filter client-side by the `time` field
+- Note any limitations in the report
+
+### Enriching Change Details
+
+For detailed audit, use `extras_get_object_change` with the change ID to see:
+- `prechange_data` - Object state before change
+- `postchange_data` - Object state after change
+- `request_id` - Links related changes in same request
+
+### Security Audit Mode
+
+If user asks for "security audit" or "compliance report":
+1. Focus on deletions and permission-sensitive changes
+2. Highlight changes to critical objects (firewalls, VRFs, prefixes)
+3. Flag changes outside business hours
+4. Identify users with high change counts
+
+## Examples
+
+- `/change-audit` - Show recent changes (last 24 hours)
+- `/change-audit last 7 days` - Changes in past week
+- `/change-audit by admin` - All changes by admin user
+- `/change-audit type dcim.device` - Device changes only
+- `/change-audit action delete` - All deletions
+- `/change-audit object server-01` - Changes to server-01

+
+# CMDB Data Quality Audit
+
+Analyze NetBox data for quality issues and best practice violations.
+
+## Usage
+
+```
+/cmdb-audit [scope]
+```
+
+**Scopes:**
+- `all` (default) - Full audit across all categories
+- `vms` - Virtual machines only
+- `devices` - Physical devices only
+- `naming` - Naming convention analysis
+- `roles` - Role fragmentation analysis
+
+## Instructions
+
+You are a data quality auditor for NetBox. Your job is to identify consistency issues and best practice violations.
+
+**IMPORTANT:** Load the `netbox-patterns` skill for best practice reference.
+
+### Phase 1: Data Collection
+
+Run these MCP tool calls to gather data for analysis:
+
+```
+1. virt_list_vms (no filters - get all)
+2. dcim_list_devices (no filters - get all)
+3. virt_list_clusters (no filters)
+4. dcim_list_sites
+5. tenancy_list_tenants
+6. dcim_list_device_roles
+7. dcim_list_platforms
+```
+
+Store the results for analysis.
+
+### Phase 2: Quality Checks
+
+Analyze collected data for these issues by severity:
+
+#### CRITICAL Issues (must fix immediately)
+
+| Check | Detection |
+|-------|-----------|
+| VMs without cluster | `cluster` field is null AND `site` field is null |
+| Devices without site | `site` field is null |
+| Active devices without primary IP | `status=active` AND `primary_ip4` is null AND `primary_ip6` is null |
+
+#### HIGH Issues (should fix soon)
+
+| Check | Detection |
+|-------|-----------|
+| VMs without site | VM has no site (neither direct nor via cluster.site) |
+| VMs without tenant | `tenant` field is null |
+| Devices without platform | `platform` field is null |
+| Clusters not scoped to site | `site` field is null on cluster |
+| VMs without role | `role` field is null |
+
+#### MEDIUM Issues (plan to address)
+
+| Check | Detection |
+|-------|-----------|
+| Inconsistent naming | Names don't match patterns: devices=`{role}-{site}-{num}`, VMs=`{env}-{app}-{num}` |
+| Role fragmentation | More than 10 device roles with <3 assignments each |
+| Missing tags on production | Active resources without any tags |
+| Mixed naming separators | Some names use `_`, others use `-` |
+
+#### LOW Issues (informational)
+
+| Check | Detection |
+|-------|-----------|
+| Docker containers as VMs | Cluster type is "Docker Compose" - document this modeling choice |
+| VMs without description | `description` field is empty |
+| Sites without physical address | `physical_address` is empty |
+| Devices without serial | `serial` field is empty |
+
+### Phase 3: Naming Convention Analysis
+
+For naming scope, analyze patterns:
+
+1. **Extract naming patterns** from existing objects
+2. **Identify dominant patterns** (most common conventions)
+3. **Flag outliers** that don't match dominant patterns
+4. **Suggest standardization** based on best practices
+
+**Expected Patterns:**
+- Devices: `{role}-{location}-{number}` (e.g., `web-dc1-01`)
+- VMs: `{prefix}_{service}` or `{env}-{app}-{number}` (e.g., `prod-api-01`)
+- Clusters: `{site}-{type}` (e.g., `home-docker`)
+
+### Phase 4: Role Analysis
+
+For roles scope, analyze fragmentation:
+
+1. **List all device roles** with assignment counts
+2. **Identify single-use roles** (only 1 device/VM)
+3. **Identify similar roles** that could be consolidated
+4. **Suggest consolidation** based on patterns
+
+**Red Flags:**
+- More than 15 highly specific roles
+- Roles with technology in name (use platform instead)
+- Roles that duplicate functionality
+
+### Phase 5: Report Generation
+
+Present findings in this structure:
+
+```markdown
+## CMDB Data Quality Audit Report
+
+**Generated:** [timestamp]
+**Scope:** [scope parameter]
+
+### Summary
+
+| Metric | Count |
+|--------|-------|
+| Total VMs | X |
+| Total Devices | Y |
+| Total Clusters | Z |
+| **Total Issues** | **N** |
+
+| Severity | Count |
+|----------|-------|
+| Critical | A |
+| High | B |
+| Medium | C |
+| Low | D |
+
+### Critical Issues
+
+[List each with specific object names and IDs]
+
+**Example:**
+- VM `HotServ` (ID: 1) - No cluster or site assignment
+- Device `server-01` (ID: 5) - No site assignment
+
+### High Issues
+
+[List each with specific object names]
+
+### Medium Issues
+
+[Grouped by category with counts]
+
+### Recommendations
+
+1. **[Most impactful fix]** - affects N objects
+2. **[Second priority]** - affects M objects
+...
+
+### Quick Fixes
+
+Commands to fix common issues:
+
+```
+# Assign site to VM
+virt_update_vm id=X site=Y
+
+# Assign platform to device
+dcim_update_device id=X platform=Y
+```
+
+### Next Steps
+
+- Run `/cmdb-register` to properly register new machines
+- Use `/cmdb-sync` to update existing registrations
+- Consider bulk updates via NetBox web UI for >10 items
+```
+
+## Scope-Specific Instructions
+
+### For `vms` scope:
+Focus only on Virtual Machine checks. Skip device and role analysis.
+
+### For `devices` scope:
+Focus only on Device checks. Skip VM and cluster analysis.
+
+### For `naming` scope:
+Focus on naming convention analysis across all objects. Generate detailed pattern report.

+
+# CMDB Machine Registration
+
+Register the current machine into NetBox, including hardware info, network interfaces, and running applications (Docker containers, services).
+
+## Usage
+
+```
+/cmdb-register [--site <site-name>] [--tenant <tenant-name>] [--role <role-name>]
+```
+
+**Options:**
+- `--site <name>`: Site to assign (will prompt if not provided)
+- `--tenant <name>`: Tenant for resource isolation (optional)
+- `--role <name>`: Device role (default: auto-detect based on services)
+
+## Instructions
+
+You are registering the current machine into NetBox. This is a multi-phase process that discovers local system information and creates corresponding NetBox objects.
+
+**IMPORTANT:** Load the `netbox-patterns` skill for best practice reference.
+
+### Phase 1: System Discovery (via Bash)
+
+Gather system information using these commands:
+
+#### 1.1 Basic Device Info
+
+```bash
+# Hostname
+hostname
+
+# OS/Platform info
+cat /etc/os-release 2>/dev/null || uname -a
+
+# Hardware model (varies by system)
+# Raspberry Pi:
+cat /proc/device-tree/model 2>/dev/null || echo "Unknown"
+
+# x86 systems:
+cat /sys/class/dmi/id/product_name 2>/dev/null || echo "Unknown"
+
+# Serial number
+# Raspberry Pi:
+cat /proc/device-tree/serial-number 2>/dev/null || cat /proc/cpuinfo | grep Serial | cut -d: -f2 | tr -d ' ' 2>/dev/null
+
+# x86 systems:
+cat /sys/class/dmi/id/product_serial 2>/dev/null || echo "Unknown"
+
+# CPU info
+nproc
+
+# Memory (MB)
+free -m | awk '/Mem:/ {print $2}'
+
+# Disk (GB, root filesystem)
+df -BG / | awk 'NR==2 {print $2}' | tr -d 'G'
+```
+
+#### 1.2 Network Interfaces
+
+```bash
+# Get interfaces with IPs (JSON format)
+ip -j addr show 2>/dev/null || ip addr show
+
+# Get default gateway interface
+ip route | grep default | awk '{print $5}' | head -1
+
+# Get MAC addresses
+ip -j link show 2>/dev/null || ip link show
+```
+
+#### 1.3 Running Applications
+
+```bash
+# Docker containers (if docker available)
+docker ps --format '{"name":"{{.Names}}","image":"{{.Image}}","status":"{{.Status}}","ports":"{{.Ports}}"}' 2>/dev/null || echo "Docker not available"
+
+# Docker Compose projects (check common locations)
+find ~/apps /home/*/apps -name "docker-compose.yml" -o -name "docker-compose.yaml" 2>/dev/null | head -20
+
+# Systemd services (running)
+systemctl list-units --type=service --state=running --no-pager --plain 2>/dev/null | grep -v "^UNIT" | head -30
+```
+
+### Phase 2: Pre-Registration Checks (via MCP)
+
+Before creating objects, verify prerequisites:
+
+#### 2.1 Check if Device Already Exists
+
+```
+dcim_list_devices name=<hostname>
+```
+
+**If device exists:**
+- Inform user and suggest `/cmdb-sync` instead
+- Ask if they want to proceed with re-registration (will update existing)
+
+#### 2.2 Verify/Create Site
+
+If `--site` provided:
+```
+dcim_list_sites name=<site-name>
+```
+
+If site doesn't exist, ask user if they want to create it.
+
+If no site provided, list available sites and ask user to choose:
+```
+dcim_list_sites
+```
+
+#### 2.3 Verify/Create Platform
+
+Based on OS detected, check if platform exists:
+```
+dcim_list_platforms name=<platform-name>
+```
+
+**Platform naming:**
+- `Raspberry Pi OS (Bookworm)` for Raspberry Pi
+- `Ubuntu 24.04 LTS` for Ubuntu
+- `Debian 12` for Debian
+- Use format: `{OS Name} {Version}`
+
+If platform doesn't exist, create it:
+```
+dcim_create_platform name=<platform-name> slug=<slug>
+```
+
+#### 2.4 Verify/Create Device Role
+
+Based on detected services:
+- If Docker containers found → `Docker Host`
+- If only basic services → `Server`
+- If specific role specified → Use that
+
+```
+dcim_list_device_roles name=<role-name>
+```
+
+### Phase 3: Device Registration (via MCP)
+
+#### 3.1 Get/Create Manufacturer and Device Type
+
+For Raspberry Pi:
+```
+dcim_list_manufacturers name="Raspberry Pi Foundation"
+dcim_list_device_types manufacturer_id=X model="Raspberry Pi 4 Model B"
+```
+
+Create if not exists.
+
+For generic x86:
+```
+dcim_list_manufacturers name=<detected-manufacturer>
+```
+
+#### 3.2 Create Device
+
+```
+dcim_create_device
+  name=<hostname>
+  device_type=<device_type_id>
+  role=<role_id>
+  site=<site_id>
+  platform=<platform_id>
+  tenant=<tenant_id>  # if provided
+  serial=<serial>
+  description="Registered via cmdb-assistant"
+```
+
+#### 3.3 Create Interfaces
+
+For each network interface discovered:
+```
+dcim_create_interface
+  device=<device_id>
+  name=<interface_name>  # eth0, wlan0, tailscale0, etc.
+  type=<type>            # 1000base-t, virtual, other
+  mac_address=<mac>
+  enabled=true
+```
+
+**Interface type mapping:**
+- `eth*`, `enp*` → `1000base-t`
+- `wlan*` → `ieee802.11ax` (or appropriate wifi type)
+- `tailscale*`, `docker*`, `br-*` → `virtual`
+- `lo` → skip (loopback)
+
+#### 3.4 Create IP Addresses
+
+For each IP on each interface:
+```
+ipam_create_ip_address
+  address=<ip/prefix>    # e.g., "192.168.1.100/24"
+  assigned_object_type="dcim.interface"
+  assigned_object_id=<interface_id>
+  status="active"
+  description="Discovered via cmdb-register"
+```
+
+#### 3.5 Set Primary IP
+
+Identify primary IP (interface with default route):
+```
+dcim_update_device
+  id=<device_id>
+  primary_ip4=<primary_ip_id>
+```
+
+### Phase 4: Container Registration (via MCP)
+
+If Docker containers were discovered:
+
+#### 4.1 Create/Get Cluster Type
+
+```
+virt_list_cluster_types name="Docker Compose"
+```
+
+Create if not exists:
+```
+virt_create_cluster_type name="Docker Compose" slug="docker-compose"
+```
+
+#### 4.2 Create Cluster
+
+For each Docker Compose project directory found:
+```
+virt_create_cluster
+  name=<project-name>  # e.g., "apps-hotport"
+  type=<cluster_type_id>
+  site=<site_id>
+  description="Docker Compose stack on <hostname>"
+```
+
+#### 4.3 Create VMs for Containers
+
+For each running container:
+```
+virt_create_vm
+  name=<container_name>
+  cluster=<cluster_id>
+  site=<site_id>
+  role=<role_id>        # Map container function to role
+  status="active"
+  vcpus=<cpu_shares>    # Default 1.0 if unknown
+  memory=<memory_mb>    # Default 256 if unknown
+  disk=<disk_gb>        # Default 5 if unknown
+  description=<container purpose>
+  comments=<image, ports, volumes info>
+```
+
+**Container role mapping:**
+- `*caddy*`, `*nginx*`, `*traefik*` → "Reverse Proxy"
+- `*db*`, `*postgres*`, `*mysql*`, `*redis*` → "Database"
+- `*webui*`, `*frontend*` → "Web Application"
+- Others → Infer from image name or use generic "Container"
+
+### Phase 5: Documentation
+
+#### 5.1 Add Journal Entry
+
+```
+extras_create_journal_entry
+  assigned_object_type="dcim.device"
+  assigned_object_id=<device_id>
+  comments="Device registered via /cmdb-register command\n\nDiscovered:\n- X network interfaces\n- Y IP addresses\n- Z Docker containers"
+```
+
+### Phase 6: Summary Report
+
+Present registration summary:
+
+```markdown

+description: Synchronize current machine state with existing NetBox record
+---
+
+# CMDB Machine Sync
+
+Update an existing NetBox device record with the current machine state. Compares local system information with NetBox and applies changes.
+
+## Usage
+
+```
+/cmdb-sync [--full] [--dry-run]
+```
+
+**Options:**
+- `--full`: Force refresh all fields, even unchanged ones
+- `--dry-run`: Show what would change without applying updates
+
+## Instructions
+
+You are synchronizing the current machine's state with its NetBox record. This involves comparing current system state with stored data and updating differences.
+
+**IMPORTANT:** Load the `netbox-patterns` skill for best practice reference.
+
+### Phase 1: Device Lookup (via MCP)
+
+First, find the existing device record:
+
+```bash
+# Get current hostname
+hostname
+```
+
+```
+dcim_list_devices name=<hostname>
+```
+
+**If device not found:**
+- Inform user: "Device '<hostname>' not found in NetBox"
+- Suggest: "Run `/cmdb-register` to register this machine first"
+- Exit sync
+
+**If device found:**
+- Store device ID and all current field values
+- Fetch interfaces: `dcim_list_interfaces device_id=<device_id>`
+- Fetch IPs: `ipam_list_ip_addresses device_id=<device_id>`
+
+Also check for associated clusters/VMs:
+```
+virt_list_clusters  # Look for cluster associated with this device
+virt_list_vms cluster=<cluster_id>  # If cluster found
+```
+
+### Phase 2: Current State Discovery (via Bash)
+
+Gather current system information (same as `/cmdb-register`):
+
+```bash
+# Device info
+hostname
+cat /etc/os-release 2>/dev/null || uname -a
+nproc
+free -m | awk '/Mem:/ {print $2}'
+df -BG / | awk 'NR==2 {print $2}' | tr -d 'G'
+
+# Network interfaces with IPs
+ip -j addr show 2>/dev/null || ip addr show
+
+# Docker containers
+docker ps --format '{"name":"{{.Names}}","image":"{{.Image}}","status":"{{.Status}}"}' 2>/dev/null || echo "[]"
+```
+
+### Phase 3: Comparison
+
+Compare discovered state with NetBox record:
+
+#### 3.1 Device Attributes
+
+| Field | Compare |
+|-------|---------|
+| Platform | OS version changed? |
+| Status | Still active? |
+| Serial | Match? |
+| Description | Keep existing |
+
+#### 3.2 Network Interfaces
+
+| Change Type | Detection |
+|-------------|-----------|
+| New interface | Interface exists locally but not in NetBox |
+| Removed interface | Interface in NetBox but not locally |
+| Changed MAC | MAC address different |
+| Interface type | Type mismatch |
+
+#### 3.3 IP Addresses
+
+| Change Type | Detection |
+|-------------|-----------|
+| New IP | IP exists locally but not in NetBox |
+| Removed IP | IP in NetBox but not locally (on this device) |
+| Primary IP changed | Default route interface changed |
+
+#### 3.4 Docker Containers
+
+| Change Type | Detection |
+|-------------|-----------|
+| New container | Container running locally but no VM in cluster |
+| Stopped container | VM exists but container not running |
+| Resource change | vCPUs/memory different (if trackable) |
+
+### Phase 4: Diff Report
+
+Present changes to user:
+
+```markdown
+## Sync Diff Report
+
+**Device:** <hostname> (ID: <device_id>)
+**NetBox URL:** https://netbox.example.com/dcim/devices/<id>/

+
+Proceed with sync? [Y/n]
+```
+
+**Use AskUserQuestion** to get confirmation.
+
+### Phase 6: Apply Updates (via MCP)
+
+Only if user confirms (or `--full` specified):
+
+#### 6.1 Device Updates
+
+```
+dcim_update_device
+  id=<device_id>

+```
+
+**For removed IPs:**
+```
+ipam_update_ip_address
+  id=<ip_id>
+  assigned_object_type=null
+  assigned_object_id=null
+  description="Unassigned by cmdb-sync"
+```
+
+#### 6.4 Primary IP Update
+
+If primary IP changed:
+```
+dcim_update_device

+description: Detect IP address conflicts and overlapping prefixes in NetBox
+---
+
+# CMDB IP Conflict Detection
+
+Scan NetBox IPAM data to identify IP address conflicts and overlapping prefixes.
+
+## Usage
+
+```
+/ip-conflicts [scope]
+```
+
+**Scopes:**
+- `all` (default) - Full scan of all IP data
+- `addresses` - Check for duplicate IP addresses only
+- `prefixes` - Check for overlapping prefixes only
+- `vrf <name>` - Scan specific VRF only
+- `prefix <cidr>` - Scan within specific prefix
+
+## Instructions
+
+You are an IP conflict detection specialist that analyzes NetBox IPAM data for conflicts and issues.
+
+### Conflict Types to Detect
+
+#### 1. Duplicate IP Addresses
+
+Multiple IP address records with the same address (within same VRF).
+
+**Detection:**
+1. Use `ipam_list_ip_addresses` to get all addresses
+2. Group by address + VRF combination
+3. Flag groups with more than one record
+
+**Exception:** Anycast addresses may legitimately appear multiple times - check the `role` field for "anycast".
+
+#### 2. Overlapping Prefixes
+
+Prefixes that contain the same address space (within same VRF).
+
+**Detection:**
+1. Use `ipam_list_prefixes` to get all prefixes
+2. For each prefix pair in the same VRF, check if one contains the other
+3. Legitimate hierarchies should have proper parent-child relationships
+
+**Legitimate Overlaps:**
+- Parent/child prefix hierarchy (e.g., 10.0.0.0/8 contains 10.0.1.0/24)
+- Different VRFs (isolated routing tables)
+- Marked as "container" status
+
+#### 3. IPs Outside Their Prefix
+
+IP addresses that don't fall within any defined prefix.
+
+**Detection:**
+1. For each IP address, find the most specific prefix that contains it
+2. Flag IPs with no matching prefix
+
+#### 4. Prefix Overlap Across VRFs (Informational)
+
+Same prefix appearing in multiple VRFs - not necessarily a conflict, but worth noting.
+
+### MCP Tools
+
+- `ipam_list_ip_addresses` - Get all IP addresses with filters:
+  - `address` - Filter by specific address
+  - `vrf_id` - Filter by VRF
+  - `parent` - Filter by parent prefix
+  - `status` - Filter by status
+
+- `ipam_list_prefixes` - Get all prefixes with filters:
+  - `prefix` - Filter by prefix CIDR
+  - `vrf_id` - Filter by VRF
+  - `within` - Find prefixes within a parent
+  - `contains` - Find prefixes containing an address
+
+- `ipam_list_vrfs` - List VRFs for context
+- `ipam_get_ip_address` - Get detailed IP info including assigned device/interface
+- `ipam_get_prefix` - Get detailed prefix info
+
+### Workflow
+
+1. **Data Collection**
+   - Fetch all IP addresses (or filtered set)
+   - Fetch all prefixes (or filtered set)
+   - Fetch VRFs for context
+
+2. **Duplicate Detection**
+   - Build address map: `{address+vrf: [records]}`
+   - Filter for entries with >1 record
+
+3. **Overlap Detection**
+   - For each VRF, compare prefixes pairwise
+   - Check using CIDR math: does prefix A contain prefix B or vice versa?
+   - Ignore legitimate hierarchies (status=container)
+
+4. **Orphan IP Detection**
+   - For each IP, find containing prefix
+   - Flag IPs with no prefix match
+
+5. **Generate Report**
+
+### Report Format

+## IP Conflict Detection Report
+
+**Generated:** [timestamp]
+**Scope:** [scope parameter]
+
+### Summary
+
+| Check | Status | Count |
+|-------|--------|-------|
+| Duplicate IPs | [PASS/FAIL] | X |
+| Overlapping Prefixes | [PASS/FAIL] | Y |
+| Orphan IPs | [PASS/FAIL] | Z |
+| Total Issues | - | N |
+
+### Critical Issues
+
+#### Duplicate IP Addresses
+
+| Address | VRF | Count | Assigned To |
+|---------|-----|-------|-------------|
+| 10.0.1.50/24 | Global | 2 | server-01 (eth0), server-02 (eth0) |
+| 192.168.1.100/24 | Global | 2 | router-01 (gi0/1), switch-01 (vlan10) |
+
+**Impact:** IP conflicts cause network connectivity issues. Devices will have intermittent connectivity.
+
+**Resolution:**
+- Determine which device should have the IP
+- Update or remove the duplicate assignment
+- Consider IP reservation to prevent future conflicts
+
+#### Overlapping Prefixes
+
+| Prefix 1 | Prefix 2 | VRF | Type |
+|----------|----------|-----|------|
+| 10.0.0.0/24 | 10.0.0.0/25 | Global | Unstructured overlap |
+| 192.168.0.0/16 | 192.168.1.0/24 | Production | Missing container flag |
+
+**Impact:** Overlapping prefixes can cause routing ambiguity and IP management confusion.
+
+**Resolution:**
+- For legitimate hierarchies: Mark parent prefix as status="container"
+- For accidental overlaps: Consolidate or re-address one prefix
+
+### Warnings
+
+#### IPs Without Prefix
+
+| Address | VRF | Assigned To | Nearest Prefix |
+|---------|-----|-------------|----------------|
+| 172.16.5.10/24 | Global | server-03 (eth0) | None found |
+
+**Impact:** IPs without a prefix bypass IPAM allocation controls.
+
+**Resolution:**
+- Create appropriate prefix to contain the IP
+- Or update IP to correct address within existing prefix
+
+### Informational
+
+#### Same Prefix in Multiple VRFs
+
+| Prefix | VRFs | Purpose |
+|--------|------|---------|
+| 10.0.0.0/24 | Global, DMZ, Internal | [Check if intentional] |
+
+### Statistics
+
+| Metric | Value |
+|--------|-------|
+| Total IP Addresses | X |
+| Total Prefixes | Y |
+| Total VRFs | Z |
+| Utilization (IPs/Prefix space) | W% |
+
+### Remediation Commands
+
+```
+# Remove duplicate IP (keep server-01's assignment)
+ipam_delete_ip_address id=123
+
+# Mark prefix as container
+ipam_update_prefix id=456 status=container
+
+# Create missing prefix for orphan IP
+ipam_create_prefix prefix=172.16.5.0/24 status=active
+```
+```
+
+### CIDR Math Reference
+
+For overlap detection, use these rules:
+- Prefix A **contains** Prefix B if: A.network <= B.network AND A.broadcast >= B.broadcast
+- Two prefixes **overlap** if: A.network <= B.broadcast AND B.network <= A.broadcast
+
+**Example:**
+- 10.0.0.0/8 contains 10.0.1.0/24 (legitimate hierarchy)
+- 10.0.0.0/24 and 10.0.0.128/25 overlap (10.0.0.128/25 is within 10.0.0.0/24)
+
+### Severity Levels
+
+| Issue | Severity | Description |
+|-------|----------|-------------|
+| Duplicate IP (same interface type) | CRITICAL | Active conflict, causes outages |
+| Duplicate IP (different roles) | HIGH | Potential conflict |
+| Overlapping prefixes (same status) | HIGH | IPAM management issue |
+| Overlapping prefixes (container ok) | LOW | May need status update |
+| Orphan IP | MEDIUM | Bypasses IPAM controls |
+
+## Examples
+
+- `/ip-conflicts` - Full scan for all conflicts
+- `/ip-conflicts addresses` - Check only for duplicate IPs
+- `/ip-conflicts prefixes` - Check only for overlapping prefixes
+- `/ip-conflicts vrf Production` - Scan only Production VRF
+- `/ip-conflicts prefix 10.0.0.0/8` - Scan within specific prefix range

+
+## CRITICAL: Dependency Order
+
+Objects must be created in this order due to foreign key dependencies. Creating objects out of order results in validation errors.
+
+```
+1. ORGANIZATION (no dependencies)
+   ├── Tenant Groups
+   ├── Tenants (optional: Tenant Group)
+   ├── Regions
+   ├── Site Groups
+   └── Tags
+
+2. SITES AND LOCATIONS
+   ├── Sites (optional: Region, Site Group, Tenant)
+   └── Locations (requires: Site, optional: parent Location)
+
+3. DCIM PREREQUISITES
+   ├── Manufacturers
+   ├── Device Types (requires: Manufacturer)
+   ├── Platforms
+   ├── Device Roles
+   └── Rack Roles
+
+4. RACKS
+   └── Racks (requires: Site, optional: Location, Rack Role, Tenant)
+
+5. DEVICES
+   ├── Devices (requires: Device Type, Role, Site; optional: Rack, Location)
+   └── Interfaces (requires: Device)
+
+6. VIRTUALIZATION
+   ├── Cluster Types
+   ├── Cluster Groups
+   ├── Clusters (requires: Cluster Type, optional: Site)
+   ├── Virtual Machines (requires: Cluster OR Site)
+   └── VM Interfaces (requires: Virtual Machine)
+
+7. IPAM
+   ├── VRFs (optional: Tenant)
+   ├── Prefixes (optional: VRF, Site, Tenant)
+   ├── IP Addresses (optional: VRF, Tenant, Interface)
+   └── VLANs (optional: Site, Tenant)
+
+8. CONNECTIONS (last)
+   └── Cables (requires: endpoints)
+```
+
+**Key Rule:** NEVER create a VM before its cluster exists. NEVER create a device before its site exists.
+
+## HIGH: Site Assignment
+
+**All infrastructure objects should have a site:**
+
+| Object Type | Site Requirement |
+|-------------|------------------|
+| Devices | **REQUIRED** |
+| Racks | **REQUIRED** |
+| VMs | RECOMMENDED (via cluster or direct) |
+| Clusters | RECOMMENDED |
+| Prefixes | RECOMMENDED |
+| VLANs | RECOMMENDED |
+
+**Why Sites Matter:**
+- Location-based queries and filtering
+- Power and capacity budgeting
+- Physical inventory tracking
+- Compliance and audit requirements
+
+## HIGH: Tenant Usage
+
+Use tenants for logical resource separation:
+
+**When to Use Tenants:**
+- Multi-team environments (assign resources to teams)
+- Multi-customer scenarios (MSP, hosting)
+- Cost allocation requirements
+- Access control boundaries
+
+**Apply Tenants To:**
+- Sites (who owns the physical location)
+- Devices (who operates the hardware)
+- VMs (who owns the workload)
+- Prefixes (who owns the IP space)
+- VLANs (who owns the network segment)
+
+## HIGH: Platform Tracking
+
+Platforms track OS/runtime information for automation and lifecycle management.
+
+**Platform Examples:**
+| Device Type | Platform Examples |
+|-------------|-------------------|
+| Servers | Ubuntu 24.04, Windows Server 2022, RHEL 9 |
+| Network | Cisco IOS 17.x, Junos 23.x, Arista EOS |
+| Raspberry Pi | Raspberry Pi OS (Bookworm), Ubuntu Server ARM |
+| Containers | Docker Container (as runtime indicator) |
+
+**Benefits:**
+- Vulnerability tracking (CVE correlation)
+- Configuration management integration
+- Lifecycle management (EOL tracking)
+- Automation targeting
+
+## MEDIUM: Tag Conventions
+
+Use tags for cross-cutting classification that spans object types.
+
+**Recommended Tag Patterns:**
+
+| Pattern | Purpose | Examples |
+|---------|---------|----------|
+| `env:*` | Environment classification | `env:production`, `env:staging`, `env:development` |
+| `app:*` | Application grouping | `app:web`, `app:database`, `app:monitoring` |
+| `team:*` | Ownership | `team:platform`, `team:infra`, `team:devops` |
+| `backup:*` | Backup policy | `backup:daily`, `backup:weekly`, `backup:none` |
+| `monitoring:*` | Monitoring level | `monitoring:critical`, `monitoring:standard` |
+
+**Tags vs Custom Fields:**
+- Tags: Cross-object classification, multiple values, filtering
+- Custom Fields: Object-specific structured data, single values, reporting
+
+## MEDIUM: Naming Conventions
+
+Consistent naming improves searchability and automation compatibility.
+
+**Recommended Patterns:**
+
+| Object Type | Pattern | Examples |
+|-------------|---------|----------|
+| Devices | `{role}-{location}-{number}` | `web-dc1-01`, `db-cloud-02`, `fw-home-01` |
+| VMs | `{env}-{app}-{number}` | `prod-api-01`, `dev-worker-03` |
+| Clusters | `{site}-{type}` | `dc1-vmware`, `home-docker` |
+| Prefixes | Include purpose in description | "Production web tier /24" |
+| VLANs | `{site}-{function}` | `dc1-mgmt`, `home-iot` |
+
+**Avoid:**
+- Inconsistent casing (mixing `HotServ` and `hotserv`)
+- Mixed separators (mixing `hhl_cluster` and `media-cluster`)
+- Generic names without context (`server1`, `vm2`)
+- Special characters other than hyphen
+
+## MEDIUM: Role Consolidation
+
+Avoid role fragmentation - use general roles with platform/tags for specificity.
+
+**Instead of:**
+```
+nginx-web-server
+apache-web-server
+web-server-frontend
+web-server-api
+```
+
+**Use:**
+```
+web-server (role) + platform (nginx/apache) + tags (frontend, api)
+```
+
+**Recommended Role Categories:**
+
+| Category | Roles |
+|----------|-------|
+| Infrastructure | `hypervisor`, `storage-server`, `network-device`, `firewall` |
+| Compute | `application-server`, `database-server`, `web-server`, `api-server` |
+| Services | `container-host`, `load-balancer`, `monitoring-server`, `backup-server` |
+| Development | `development-workstation`, `ci-runner`, `build-server` |
+| Containers | `reverse-proxy`, `database`, `cache`, `queue`, `worker` |
+
+## Docker Containers as VMs
+
+NetBox's Virtualization module can model Docker containers:
+
+**Approach:**
+1. Create device for physical Docker host
+2. Create cluster (type: "Docker Compose" or "Docker Swarm")
+3. Associate cluster with host device
+4. Create VMs for each container in the cluster
+
+**VM Fields for Containers:**
+- `name`: Container name (e.g., `media_jellyfin`)
+- `role`: Container function (e.g., `Media Server`)
+- `vcpus`: CPU limit/shares
+- `memory`: Memory limit (MB)
+- `disk`: Volume size estimate
+- `description`: Container purpose
+- `comments`: Image, ports, volumes, dependencies
+
+**This is a pragmatic modeling choice** - containers aren't VMs, but the Virtualization module is the closest fit for tracking container workloads.
+
+## Primary IP Workflow
+
+To set a device/VM's primary IP:
+
+1. Create interface on device/VM
+2. Create IP address assigned to interface
+3. Set IP as `primary_ip4` or `primary_ip6` on device/VM
+
+**Why Primary IP Matters:**
+- Used for device connectivity checks
+- Displayed in device list views
+- Used by automation tools (NAPALM, Ansible)
+- Required for many integrations
+
+## Data Quality Checklist
+
+Before closing a sprint or audit:
+
+- [ ] All VMs have site assignment (direct or via cluster)
+- [ ] All VMs have tenant assignment
+- [ ] All active devices have platform
+- [ ] All active devices have primary IP
+- [ ] Naming follows conventions
+- [ ] No orphaned prefixes (allocated but unused)
+- [ ] Tags applied consistently
+- [ ] Clusters scoped to sites
+- [ ] Roles not overly fragmented
+
+## MCP Tool Reference
+
+**Dependency Order for Creation:**
+```
+1. dcim_create_site
+2. dcim_create_manufacturer
+3. dcim_create_device_type
+4. dcim_create_device_role
+5. dcim_create_platform
+6. dcim_create_device
+7. virt_create_cluster_type
+8. virt_create_cluster
+9. virt_create_vm
+10. dcim_create_interface / virt_create_vm_interface
+11. ipam_create_ip_address
+12. dcim_update_device (set primary_ip4)
+```
+
+**Lookup Before Create:**
+Always check if object exists before creating to avoid duplicates:
+```
+1. dcim_list_devices name=<hostname>
+2. If exists, update; if not, create
+```

+# contract-validator Plugin
+
+Cross-plugin compatibility validation and CLAUDE.md agent verification for Claude Code plugin marketplaces.
+
+## Problem Statement
+
+As plugin marketplaces grow, several compatibility issues emerge:
+
+- **Command conflicts**: Multiple plugins defining the same slash command (e.g., `/initial-setup`)
+- **Tool name overlaps**: Different plugins using identical tool names with incompatible interfaces
+- **Undocumented dependencies**: Agents referencing tools that don't exist
+- **Broken data flows**: Agent sequences that expect outputs not produced by prior steps
+
+Contract-validator solves these by parsing plugin interfaces and validating compatibility before runtime.
+
+## Features
+
+- **Interface Parsing**: Extract commands, agents, and tools from plugin README.md files
+- **Agent Extraction**: Parse CLAUDE.md Four-Agent Model tables and Agents sections
+- **Compatibility Checks**: Pairwise validation between all plugins in a marketplace
+- **Data Flow Validation**: Verify agent tool sequences have valid data producers/consumers
+- **Dependency Visualization**: Generate Mermaid flowcharts showing plugin relationships
+- **Comprehensive Reports**: Markdown or JSON reports with actionable suggestions
+
+## Installation
+
+This plugin is part of the leo-claude-mktplace. Install via:

+| `optional_dependency` | WARNING | Agent uses tool from non-required plugin |
+| `undeclared_output` | INFO | Agent has no documented tool references |
+
+## Parsed Interface Structure
+
+When parsing a plugin README.md, the following structure is extracted:
+
+```json
+{
+  "plugin_name": "data-platform",
+  "description": "Data engineering tools...",
+  "commands": [
+    {"name": "/ingest", "description": "Load data..."}
+  ],
+  "agents": [
+    {"name": "data-analysis", "description": "..."}
+  ],
+  "tools": [
+    {"name": "read_csv", "category": "pandas"}
+  ],
+  "tool_categories": {
+    "pandas": ["read_csv", "to_csv", ...],
+    "PostgreSQL": ["pg_query", ...]
+  },
+  "features": ["pandas Operations", "PostgreSQL/PostGIS", ...]
+}
+```
+
+## Best Practices
+
+### For Plugin Authors
+
+1. **Use unique command names**: Prefix with plugin name if generic (e.g., `/data-setup` vs `/initial-setup`)
+2. **Document all tools**: Include tool names in README.md with backticks
+3. **Specify tool categories**: Use `### Category (N tools)` headers
+4. **Declare agent tools**: List tools used by agents in their definitions
+
+### For Marketplace Maintainers
+
+1. **Run validation before merging**: Use `/validate-contracts` in CI/CD
+2. **Review warnings**: Tool overlaps may indicate design issues
+3. **Track issues over time**: Use JSON format for programmatic tracking

+# Agent Check Agent
+
+You are an agent definition validator. Your role is to verify that a specific agent's tool references and data flow are valid.
+
+## Capabilities
+
+- Parse agent definitions from CLAUDE.md
+- Validate tool references against available plugins
+- Verify data flow patterns through agent sequences
+- Provide detailed validation feedback
+
+## Available Tools
+
+### Parsing
+- `parse_claude_md_agents` - Extract all agents from CLAUDE.md
+- `parse_plugin_interface` - Extract interface from plugin (for available tools)
+
+### Validation
+- `validate_agent_refs` - Check agent tool references exist
+- `validate_data_flow` - Verify data flow through agent sequence
+
+### Reporting
+- `list_issues` - Filter issues for this agent
+
+## Workflow
+
+1. **Locate the agent**:
+   - Use `parse_claude_md_agents` on specified CLAUDE.md
+   - Find agent by name (case-insensitive match)
+   - If not found, list available agents
+
+2. **Gather available tools**:
+   - Scan plugins directory for available plugins
+   - For each plugin, use `parse_plugin_interface`
+   - Build set of all available tool names
+
+3. **Validate tool references**:
+   - Use `validate_agent_refs` with agent name and plugin paths
+   - Report found tools (valid references)
+   - Report missing tools (errors)
+   - Suggest corrections for typos
+
+4. **Validate data flow**:
+   - Use `validate_data_flow` to check sequence
+   - Verify data producers precede consumers
+   - Check for orphaned data references
+   - Identify potential flow issues
+
+5. **Report findings**:
+   - Agent name and source file
+   - Responsibilities extracted
+   - Tool references: found vs missing
+   - Data flow validation results
+   - Suggestions for improvement
+
+## Validation Rules
+
+### Tool Reference Rules
+- All referenced tools must exist in available plugins
+- Tool names are case-sensitive
+- Partial matches suggest typos
+
+### Data Flow Rules
+- Data producers (read_csv, pg_query, etc.) should precede consumers
+- Data consumers (describe, head, to_csv, etc.) need valid data_ref
+- Workflow steps should have logical sequence
+
+## Issue Severities
+
+- **ERROR**: Tool reference not found - agent will fail
+- **WARNING**: Data flow issue - agent may produce unexpected results
+- **INFO**: Undocumented reference - consider adding documentation
+
+## Example Interaction
+
+**User**: /check-agent Orchestrator
+
+**Agent**:
+1. Parses CLAUDE.md, finds Orchestrator agent
+2. Extracts responsibilities: "Sprint execution, parallel batching, Git operations"
+3. Finds tool refs: create_issue, update_issue, search_lessons
+4. Validates against plugins: all tools found in projman/gitea
+5. Validates data flow: no data producers/consumers used
+6. Reports: "Agent Orchestrator: VALID - all 3 tool references found"
+
+**User**: /check-agent InvalidAgent
+
+**Agent**:
+1. Parses CLAUDE.md, agent not found
+2. Reports: "Agent 'InvalidAgent' not found. Available agents: Planner, Orchestrator, Executor, Code Reviewer"

+# contract-validator Plugin - CLAUDE.md Integration
+
+Add this section to your marketplace or project's CLAUDE.md to enable contract validation features.
+
+## Suggested CLAUDE.md Section
+
+```markdown
+## Contract Validation
+
+This marketplace uses the contract-validator plugin for cross-plugin compatibility checks.
+
+### Available Commands
+
+| Command | Purpose |
+|---------|---------|
+| `/validate-contracts` | Full marketplace compatibility validation |
+| `/check-agent` | Validate single agent definition |
+| `/list-interfaces` | Show all plugin interfaces |
+
+### Validation Workflow
+
+Run before merging plugin changes:
+
+1. `/validate-contracts` - Check for conflicts
+2. Review errors (must fix) and warnings (should review)
+3. Fix issues before merging
+
+### Interface Documentation Standards
+
+For plugins to be validated correctly, document interfaces in README.md:
+
+**Commands Section:**
+```markdown
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/my-command` | What it does |
+```
+
+**Tools Section:**
+```markdown
+## Tools Summary
+
+### Category (N tools)
+`tool_a`, `tool_b`, `tool_c`
+```
+
+**Agents Section:**
+```markdown
+## Agents
+
+| Agent | Description |
+|-------|-------------|
+| `my-agent` | What it does |
+```
+```
+
+## Declaring Agent Tool References
+
+For agent validation to work, document tool usage in CLAUDE.md:
+
+### Option 1: Four-Agent Model Table
+
+```markdown
+### Four-Agent Model
+
+| Agent | Personality | Responsibilities |
+|-------|-------------|------------------|
+| **Planner** | Methodical | Planning via `create_issue`, `search_lessons` |
+```
+
+### Option 2: Agent Sections
+
+```markdown
+### Planner Agent
+
+Uses these tools:
+- `create_issue` - Create planning issues
+- `search_lessons` - Find relevant lessons
+```
+
+## Best Practices for Plugin Authors
+
+### Unique Command Names
+
+Avoid generic names that may conflict:
+
+```markdown
+# BAD - Will conflict with other plugins
+| `/setup` | Setup wizard |
+
+# GOOD - Plugin-specific prefix
+| `/data-setup` | Data platform setup wizard |
+```
+
+### Document All Tools
+
+Ensure every MCP tool is listed in README.md:
+
+```markdown
+## Tools Summary
+
+### pandas (14 tools)
+`read_csv`, `read_parquet`, `read_json`, `to_csv`, `to_parquet`,
+`describe`, `head`, `tail`, `filter`, `select`, `groupby`, `join`,
+`list_data`, `drop_data`
+```
+
+### Specify Dependencies
+
+If agents depend on tools from other plugins, document it:
+
+```markdown
+## Dependencies
+
+This agent uses tools from:
+- `projman` - Issue management (`create_issue`, `update_issue`)
+- `data-platform` - Data loading (`read_csv`, `describe`)
+```
+
+## Typical Workflows
+
+### Pre-Merge Validation
+
+```
+# Before merging new plugin
+/validate-contracts
+
+# Check specific agent after changes
+/check-agent Orchestrator
+```
+
+### Plugin Development
+
+```
+# See what interfaces exist
+/list-interfaces
+
+# After adding new command, verify no conflicts
+/validate-contracts
+```
+
+### CI/CD Integration
+
+Add to your pipeline:
+
+```yaml
+- name: Validate Plugin Contracts
+  run: |
+    claude --skill contract-validator:validate-contracts --args "${{ github.workspace }}"
+```

+# /dependency-graph - Generate Dependency Visualization
+
+Generate a Mermaid flowchart showing plugin dependencies, data flows, and tool relationships.
+
+## Usage
+
+```
+/dependency-graph [marketplace_path] [--format <mermaid|text>] [--show-tools]
+```
+
+## Parameters
+
+- `marketplace_path` (optional): Path to marketplace root. Defaults to current project root.
+- `--format` (optional): Output format - `mermaid` (default) or `text`
+- `--show-tools` (optional): Include individual tool nodes in the graph
+
+## Workflow
+
+1. **Discover plugins**:
+   - Scan plugins directory for all plugins with `.claude-plugin/` marker
+   - Parse each plugin's README.md to extract interface
+   - Parse CLAUDE.md for agent definitions and tool sequences
+
+2. **Analyze dependencies**:
+   - Identify shared MCP servers (plugins using same server)
+   - Detect tool dependencies (which plugins produce vs consume data)
+   - Find agent tool references across plugins
+   - Categorize as required (ERROR if missing) or optional (WARNING if missing)
+
+3. **Build dependency graph**:
+   - Create nodes for each plugin
+   - Create edges for:
+     - Shared MCP servers (bidirectional)
+     - Data producers -> consumers (directional)
+     - Agent tool dependencies (directional)
+   - Mark edges as optional or required
+
+4. **Generate Mermaid output**:
+   - Create flowchart diagram syntax
+   - Style required dependencies with solid lines
+   - Style optional dependencies with dashed lines
+   - Group by MCP server or data flow
+
+## Output Format
+
+### Mermaid (default)
+
+```mermaid

+
+## Dependency Types
+
+| Type | Line Style | Meaning |
+|------|------------|---------|
+| Required | Solid (`-->`) | Plugin cannot function without this dependency |
+| Optional | Dashed (`-.->`) | Plugin works but with reduced functionality |
+| Internal | Dotted (`...>`) | Self-dependency within same plugin |
+| Shared MCP | Double (`==>`) | Plugins share same MCP server instance |
+
+## Known Data Flow Patterns
+
+The command recognizes these producer/consumer relationships:
+
+### Data Producers
+- `read_csv`, `read_parquet`, `read_json` - File loaders
+- `pg_query`, `pg_execute` - Database queries
+- `filter`, `select`, `groupby`, `join` - Transformations
+
+### Data Consumers
+- `describe`, `head`, `tail` - Data inspection
+- `to_csv`, `to_parquet` - File writers
+- `chart_create` - Visualization
+
+### Cross-Plugin Flows
+- `data-platform` produces `data_ref` -> `viz-platform` consumes for charts
+- `projman` produces issues -> `pr-review` references in reviews
+- `gitea` wiki -> `projman` lessons learned
+
+## Examples
+
+### Basic Usage
+
+```
+/dependency-graph
+```
+
+Generates Mermaid diagram for current marketplace.
+
+### With Tool Details
+
+```
+/dependency-graph --show-tools
+```
+
+Includes individual tool nodes showing which tools each plugin provides.
+
+### Text Summary
+
+```
+/dependency-graph --format text
+```
+
+Outputs text-based summary suitable for CLAUDE.md inclusion.
+
+### Specific Path
+
+```
+/dependency-graph ~/claude-plugins-work
+```
+
+Analyze marketplace at specified path.
+
+## Integration with Other Commands
+
+Use with `/validate-contracts` to:
+1. Run `/dependency-graph` to visualize relationships
+2. Run `/validate-contracts` to find issues in those relationships
+3. Fix issues and regenerate graph to verify
+
+## Available Tools
+
+Use these MCP tools:
+- `parse_plugin_interface` - Extract interface from plugin README.md
+- `parse_claude_md_agents` - Extract agents and their tool sequences
+- `generate_compatibility_report` - Get full interface data (JSON format for analysis)
+- `validate_data_flow` - Verify data producer/consumer relationships
+
+## Implementation Notes
+
+### Detecting Shared MCP Servers
+
+Check each plugin's `.mcp.json` file for server definitions:
+
+```bash
+# List all .mcp.json files in plugins
+find plugins/ -name ".mcp.json" -exec cat {} \;
+```
+
+Plugins with identical MCP server names share that server.
+
+### Identifying Data Flows
+
+1. Parse tool categories from README.md
+2. Map known producer tools to their output types
+3. Map known consumer tools to their input requirements
+4. Create edges where outputs match inputs
+
+### Optional vs Required
+
+- **Required**: Consumer tool has no default/fallback behavior
+- **Optional**: Consumer works without producer (e.g., lessons search returns empty)
+
+Determination is based on:
+- Issue severity from `validate_data_flow` (ERROR = required, WARNING = optional)
+- Tool documentation stating "requires" vs "uses if available"
+
+## Sample Output
+
+For the leo-claude-mktplace:

+description: Interactive setup wizard for contract-validator plugin - verifies MCP server and shows capabilities
+---
+
+# Contract-Validator Setup Wizard
+
+This command sets up the contract-validator plugin for cross-plugin compatibility validation.
+
+## Important Context
+
+- **This command uses Bash, Read, Write, and AskUserQuestion tools** - NOT MCP tools
+- **MCP tools won't work until after setup + session restart**
+- **No external credentials required** - this plugin validates local files only
+
+---
+
+## Phase 1: Environment Validation
+
+### Step 1.1: Check Python Version
+
+```bash
+python3 --version
+```
+
+Requires Python 3.10+. If below, stop setup and inform user:
+```
+Python 3.10 or higher is required. Please install it and run /initial-setup again.
+```
+
+---
+
+## Phase 2: MCP Server Setup
+
+### Step 2.1: Locate Contract-Validator MCP Server
+
+```bash
+# If running from installed marketplace
+ls -la ~/.claude/plugins/marketplaces/leo-claude-mktplace/mcp-servers/contract-validator/ 2>/dev/null || echo "NOT_FOUND_INSTALLED"
+
+# If running from source
+ls -la ~/claude-plugins-work/mcp-servers/contract-validator/ 2>/dev/null || echo "NOT_FOUND_SOURCE"
+```
+
+Determine which path exists and use that as the MCP server path.
+
+### Step 2.2: Check Virtual Environment
+
+```bash
+ls -la /path/to/mcp-servers/contract-validator/.venv/bin/python 2>/dev/null && echo "VENV_EXISTS" || echo "VENV_MISSING"
+```
+
+### Step 2.3: Create Virtual Environment (if missing)
+
+```bash
+cd /path/to/mcp-servers/contract-validator && python3 -m venv .venv && source .venv/bin/activate && pip install --upgrade pip && pip install -r requirements.txt && deactivate
+```
+
+**If pip install fails:**
+- Show the error to the user
+- Suggest: "Check your internet connection and try again."
+
+---
+
+## Phase 3: Validation
+
+### Step 3.1: Verify MCP Server
+
+```bash
+cd /path/to/mcp-servers/contract-validator && .venv/bin/python -c "from mcp_server.server import ContractValidatorMCPServer; print('MCP Server OK')"
+```
+
+If this fails, check the error and report it to the user.
+
+### Step 3.2: Summary
+
+Display:
+
+```
+╔════════════════════════════════════════════════════════════════╗
+║          CONTRACT-VALIDATOR SETUP COMPLETE                      ║

+
+### Step 3.3: Session Restart Notice
+
+---
+
+**Session Restart Required**
+
+Restart your Claude Code session for MCP tools to become available.
+
+**After restart, you can:**
+- Run `/validate-contracts` to check all plugins for compatibility issues
+- Run `/check-agent` to validate a single agent definition
+- Run `/list-interfaces` to see all plugin commands and tools
+
+---
+
+## Available Tools
+
+| Category | Tools | Description |
+|----------|-------|-------------|
+| Parse | `parse_plugin_interface`, `parse_claude_md_agents` | Extract interfaces from README.md and agents from CLAUDE.md |
+| Validation | `validate_compatibility`, `validate_agent_refs`, `validate_data_flow` | Check conflicts, tool references, and data flows |
+| Report | `generate_compatibility_report`, `list_issues` | Generate reports and filter issues |
+
+---
+
+## Available Commands
+
+| Command | Description |
+|---------|-------------|
+| `/validate-contracts` | Full marketplace compatibility validation |
+| `/check-agent` | Validate single agent definition |
+| `/list-interfaces` | Show all plugin interfaces |
+
+---
+
+## Use Cases
+
+### 1. Pre-Release Validation
+Run `/validate-contracts` before releasing a new marketplace version to catch:
+- Command name conflicts between plugins
+- Missing tool references in agents
+- Broken data flows
+
+### 2. Agent Development
+Run `/check-agent` when creating or modifying agents to verify:
+- All referenced tools exist
+- Data flows are valid
+- No undeclared dependencies
+
+### 3. Plugin Audit
+Run `/list-interfaces` to get a complete view of:
+- All commands across plugins
+- All tools available
+- Potential overlap areas
+
+---
+
+## No Configuration Required
+
+This plugin doesn't require any configuration files. It reads plugin manifests and README files directly from the filesystem.

+
+Display what each plugin in the marketplace produces and accepts.
+
+## Usage
+
+```
+/list-interfaces [marketplace_path]
+```
+
+## Parameters
+
+- `marketplace_path` (optional): Path to marketplace root. Defaults to current project root.
+
+## Workflow
+
+1. **Discover plugins**:
+   - Scan plugins directory for all plugins with `.claude-plugin/` marker
+   - Read each plugin's README.md
+
+2. **Parse interfaces**:
+   - Extract commands (slash commands offered by plugin)
+   - Extract agents (autonomous agents defined)
+   - Extract tools (MCP tools provided)
+   - Identify tool categories and features
+
+3. **Display summary**:
+   - Table of plugins with command/agent/tool counts
+   - Detailed breakdown per plugin
+   - Tool categories and their contents
+
+## Output Format
+
+```
+| Plugin      | Commands | Agents | Tools |
+|-------------|----------|--------|-------|
+| projman     | 12       | 4      | 26    |
+| data-platform| 7       | 2      | 32    |
+| ...         | ...      | ...    | ...   |
+
+## projman
+- Commands: /sprint-plan, /sprint-start, ...
+- Agents: Planner, Orchestrator, Executor, Code Reviewer
+- Tools: list_issues, create_issue, ...
+```
+
+## Examples
+
+```
+/list-interfaces
+/list-interfaces ~/claude-plugins-work
+```
+
+## Available Tools
+
+Use these MCP tools:
+- `parse_plugin_interface` - Parse individual plugin README

+# /validate-contracts - Full Contract Validation
+
+Run comprehensive cross-plugin compatibility validation for the entire marketplace.
+
+## Usage
+
+```
+/validate-contracts [marketplace_path]
+```
+
+## Parameters
+
+- `marketplace_path` (optional): Path to marketplace root. Defaults to current project root.
+
+## Workflow
+
+1. **Discover plugins**:
+   - Scan plugins directory for all plugins with `.claude-plugin/` marker
+   - Parse each plugin's README.md to extract interface
+
+2. **Run compatibility checks**:
+   - Perform pairwise compatibility validation between all plugins
+   - Check for command name conflicts
+   - Check for tool name overlaps
+   - Identify interface mismatches
+
+3. **Validate CLAUDE.md agents**:
+   - Parse agent definitions from CLAUDE.md
+   - Validate all tool references exist
+   - Check data flow through agent sequences
+
+4. **Generate report**:
+   - Summary statistics (plugins, commands, tools, issues)
+   - Detailed findings by severity (error, warning, info)
+   - Actionable suggestions for each issue
+
+## Examples
+
+```
+/validate-contracts
+/validate-contracts ~/claude-plugins-work

+# /data-quality - Data Quality Assessment
+
+Comprehensive data quality check for DataFrames with pass/warn/fail scoring.
+
+## Usage
+
+```
+/data-quality <data_ref> [--strict]
+```
+
+## Workflow
+
+1. **Get data reference**:
+   - If no data_ref provided, use `list_data` to show available options
+   - Validate the data_ref exists
+
+2. **Null analysis**:
+   - Calculate null percentage per column
+   - **PASS**: < 5% nulls
+   - **WARN**: 5-20% nulls
+   - **FAIL**: > 20% nulls
+
+3. **Duplicate detection**:
+   - Check for fully duplicated rows
+   - **PASS**: 0% duplicates
+   - **WARN**: < 1% duplicates
+   - **FAIL**: >= 1% duplicates
+
+4. **Type consistency**:
+   - Identify mixed-type columns (object columns with mixed content)
+   - Flag columns that could be numeric but contain strings
+   - **PASS**: All columns have consistent types
+   - **FAIL**: Mixed types detected
+
+5. **Outlier detection** (numeric columns):
+   - Use IQR method (values beyond 1.5 * IQR)
+   - Report percentage of outliers per column
+   - **PASS**: < 1% outliers
+   - **WARN**: 1-5% outliers
+   - **FAIL**: > 5% outliers
+
+6. **Generate quality report**:
+   - Overall quality score (0-100)
+   - Per-column breakdown
+   - Recommendations for remediation
+

+# /dbt-test - Run dbt Tests
+
+Execute dbt tests with formatted pass/fail results.
+
+## Usage
+
+```
+/dbt-test [selection] [--warn-only]
+```
+
+## Workflow
+
+1. **Pre-validation** (MANDATORY):
+   - Use `dbt_parse` to validate project first
+   - If validation fails, show errors and STOP
+
+2. **Execute tests**:
+   - Use `dbt_test` with provided selection
+   - Capture all test results
+
+3. **Format results**:
+   - Group by test type (schema vs. data)
+   - Show pass/fail status with counts
+   - Display failure details
+
+## Report Format
+
+```

+
+## Options
+
+| Flag | Description |
+|------|-------------|
+| `--warn-only` | Treat failures as warnings (don't fail CI) |
+
+## Examples
+

+/dbt-test +fct_orders              # Test model and its upstream
+```
+
+## Test Types
+
+### Schema Tests
+Built-in tests defined in `schema.yml`:
+- `unique` - No duplicate values
+- `not_null` - No null values
+- `accepted_values` - Value in allowed list
+- `relationships` - Foreign key integrity
+
+### Data Tests
+Custom SQL tests in `tests/` directory:
+- Return rows that fail the assertion
+- Zero rows = pass, any rows = fail
+
+## Exit Codes
+
+| Code | Meaning |
+|------|---------|
+| 0 | All tests passed |
+| 1 | One or more tests failed |
+| 2 | dbt error (parse failure, etc.) |
+
+## Available Tools
+
+Use these MCP tools:
+- `dbt_parse` - Pre-validation (ALWAYS RUN FIRST)
+- `dbt_test` - Execute tests (REQUIRED)
+- `dbt_build` - Alternative: run + test together

+# /lineage-viz - Mermaid Lineage Visualization
+
+Generate Mermaid flowchart syntax for dbt model lineage.
+
+## Usage
+
+```
+/lineage-viz <model_name> [--direction TB|LR] [--depth N]
+```
+
+## Workflow
+
+1. **Get lineage data**:
+   - Use `dbt_lineage` to fetch model dependencies
+   - Capture upstream sources and downstream consumers
+
+2. **Build Mermaid graph**:
+   - Create nodes for each model/source
+   - Style nodes by materialization type
+   - Add directional arrows for dependencies
+
+3. **Output**:
+   - Render Mermaid flowchart syntax
+   - Include copy-paste ready code block
+
+## Output Format
+
+```mermaid
+flowchart LR
+    subgraph Sources
+        raw_customers[(raw_customers)]
+        raw_orders[(raw_orders)]
+    end
+
+    subgraph Staging
+        stg_customers[stg_customers]
+        stg_orders[stg_orders]
+    end
+
+    subgraph Marts
+        dim_customers{{dim_customers}}
+        fct_orders{{fct_orders}}
+    end
+
+    raw_customers --> stg_customers
+    raw_orders --> stg_orders
+    stg_customers --> dim_customers
+    stg_orders --> fct_orders
+    dim_customers --> fct_orders
+```
+
+## Node Styles
+
+| Materialization | Mermaid Shape | Example |
+|-----------------|---------------|---------|
+| source | Cylinder `[( )]` | `raw_data[(raw_data)]` |
+| view | Rectangle `[ ]` | `stg_model[stg_model]` |
+| table | Double braces `{{ }}` | `dim_model{{dim_model}}` |
+| incremental | Hexagon `{{ }}` | `fct_model{{fct_model}}` |
+| ephemeral | Dashed `[/ /]` | `tmp_model[/tmp_model/]` |
+
+## Options
+
+| Flag | Description |
+|------|-------------|
+| `--direction TB` | Top-to-bottom layout (default: LR = left-to-right) |
+| `--depth N` | Limit lineage depth (default: unlimited) |
+
+## Examples
+
+```
+/lineage-viz dim_customers
+/lineage-viz fct_orders --direction TB
+/lineage-viz rpt_revenue --depth 2
+```
+
+## Usage Tips
+
+1. **Paste in documentation**: Copy the output directly into README.md or docs
+2. **GitHub/GitLab rendering**: Both platforms render Mermaid natively
+3. **Mermaid Live Editor**: Paste at https://mermaid.live for interactive editing
+
+## Example Output
+
+For `/lineage-viz fct_orders`:
+
+~~~markdown
+```mermaid
+flowchart LR
+    %% Sources
+    raw_customers[(raw_customers)]
+    raw_orders[(raw_orders)]
+    raw_products[(raw_products)]

+
+# Changelog Generation
+
+Generate a changelog entry from conventional commits.
+
+## Process
+
+1. **Identify Commit Range**
+   - Default: commits since last tag
+   - Optional: specify range (e.g., `v1.0.0..HEAD`)
+   - Detect if this is first release (no previous tags)
+
+2. **Parse Conventional Commits**
+   Extract from commit messages following the pattern:
+   ```
+   <type>(<scope>): <description>
+
+   [optional body]
+
+   [optional footer(s)]
+   ```
+
+   **Recognized Types:**
+   | Type | Changelog Section |
+   |------|------------------|
+   | `feat` | Added |
+   | `fix` | Fixed |
+   | `docs` | Documentation |
+   | `perf` | Performance |
+   | `refactor` | Changed |
+   | `style` | Changed |
+   | `test` | Testing |
+   | `build` | Build |
+   | `ci` | CI/CD |
+   | `chore` | Maintenance |
+   | `BREAKING CHANGE` | Breaking Changes |
+
+3. **Group by Type**
+   Organize commits into Keep-a-Changelog sections:
+   - Breaking Changes (if any `!` suffix or `BREAKING CHANGE` footer)
+   - Added (feat)
+   - Changed (refactor, style, perf)
+   - Deprecated
+   - Removed
+   - Fixed (fix)
+   - Security
+
+4. **Format Entries**
+   For each commit:
+   - Extract scope (if present) as prefix
+   - Use description as entry text
+   - Link to commit hash if repository URL available
+   - Include PR/issue references from footer
+
+5. **Output Format**
+```markdown
+## [Unreleased]
+
+### Breaking Changes
+- **scope**: Description of breaking change
+
+### Added
+- **scope**: New feature description
+- Another feature without scope
+
+### Changed
+- **scope**: Refactoring description
+
+### Fixed
+- **scope**: Bug fix description
+
+### Documentation
+- Updated README with new examples
+```
+
+## Options
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--from <tag>` | Start from specific tag | Latest tag |
+| `--to <ref>` | End at specific ref | HEAD |
+| `--version <ver>` | Set version header | [Unreleased] |
+| `--include-merge` | Include merge commits | false |
+| `--group-by-scope` | Group by scope within sections | false |
+
+## Integration
+
+The generated output is designed to be copied directly into CHANGELOG.md:
+- Follows [Keep a Changelog](https://keepachangelog.com) format
+- Compatible with semantic versioning
+- Excludes non-user-facing commits (chore, ci, test by default)

+## Example Usage
+
+```
+/changelog-gen
+/changelog-gen --from v1.0.0 --version 1.1.0
+/changelog-gen --include-merge --group-by-scope
+```
+
+## Non-Conventional Commits
+
+Commits not following conventional format are:
+- Listed under "Other" section
+- Flagged for manual categorization
+- Skipped if `--strict` flag is used

+
+# Documentation Coverage
+
+Analyze codebase to calculate documentation coverage metrics.
+
+## Process
+
+1. **Scan Source Files**
+   Identify all documentable items:
+
+   **Python:**
+   - Functions (def)
+   - Classes
+   - Methods
+   - Module-level docstrings
+
+   **JavaScript/TypeScript:**
+   - Functions (function, arrow functions)
+   - Classes
+   - Methods
+   - JSDoc comments
+
+   **Other Languages:**
+   - Adapt patterns for Go, Rust, etc.
+
+2. **Determine Documentation Status**
+   For each item, check:
+   - Has docstring/JSDoc comment
+   - Docstring is non-empty and meaningful (not just `pass` or `TODO`)
+   - Parameters are documented (for detailed mode)
+   - Return type is documented (for detailed mode)
+
+3. **Calculate Metrics**
+   ```
+   Coverage = (Documented Items / Total Items) * 100
+   ```
+
+   **Levels:**
+   - Basic: Item has any docstring
+   - Standard: Docstring describes purpose
+   - Complete: All parameters and return documented
+
+4. **Output Format**
+```
+## Documentation Coverage Report
+
+### Summary
+- Total documentable items: 156

+|------|-------|------------|----------|
+| Functions | 89 | 85 | 95.5% |
+| Classes | 23 | 21 | 91.3% |

+- [ ] src/models/user.py:23 `UserModel.validate()`
+```
+
+## Options
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--path <dir>` | Scan specific directory | Project root |
+| `--exclude <glob>` | Exclude files matching pattern | `**/test_*,**/*_test.*` |
+| `--include-private` | Include private members (_prefixed) | false |
+| `--include-tests` | Include test files | false |
+| `--min-coverage <pct>` | Fail if below threshold | none |
+| `--format <fmt>` | Output format (table, json, markdown) | table |
+| `--detailed` | Check parameter/return docs | false |
+
+## Thresholds
+
+Common coverage targets:
+| Level | Coverage | Description |
+|-------|----------|-------------|
+| Minimal | 60% | Basic documentation exists |
+| Good | 80% | Most public APIs documented |
+| Excellent | 95% | Comprehensive documentation |
+
+## CI Integration
+
+Use `--min-coverage` to enforce standards:
+```bash
+# Fail if coverage drops below 80%
+claude /doc-coverage --min-coverage 80
+```
+
+Exit codes:
+- 0: Coverage meets threshold (or no threshold set)
+- 1: Coverage below threshold
+
+## Example Usage
+
+```
+/doc-coverage
+/doc-coverage --path src/
+/doc-coverage --min-coverage 85 --exclude "**/generated/**"
+/doc-coverage --detailed --include-private
+```
+
+## Language Detection
+
+File extensions mapped to documentation patterns:
+| Extension | Language | Doc Format |
+|-----------|----------|------------|
+| .py | Python | Docstrings (""") |
+| .js, .ts | JavaScript/TypeScript | JSDoc (/** */) |
+| .go | Go | // comments above |
+| .rs | Rust | /// doc comments |

+   | CLAUDE.md | Configuration files, scripts |
+   | docs/module.md | src/module/**/* |
+   | Component.md | Component.tsx, Component.css |
+
+2. **Analyze Commit History**
+   For each doc file:
+   - Find last commit that modified the doc
+   - Find last commit that modified related code
+   - Count commits to code since doc was updated
+
+3. **Calculate Staleness**
+   ```
+   Commits Behind = Code Commits Since Doc Update
+   Days Behind = Days Since Doc Update - Days Since Code Update
+   ```
+
+4. **Apply Threshold**
+   Default: Flag if documentation is 10+ commits behind related code
+
+   **Staleness Levels:**
+   | Commits Behind | Level | Action |
+   |----------------|-------|--------|
+   | 0-5 | Fresh | No action needed |
+   | 6-10 | Aging | Review recommended |
+   | 11-20 | Stale | Update needed |
+   | 20+ | Critical | Immediate attention |
+
+5. **Output Format**
+```
+## Stale Documentation Report
+
+### Critical (20+ commits behind)
+| File | Last Updated | Commits Behind | Related Code |
+|------|--------------|----------------|--------------|
+| docs/api.md | 2024-01-15 | 34 | src/api/**/* |
+
+### Stale (11-20 commits behind)
+| File | Last Updated | Commits Behind | Related Code |
+|------|--------------|----------------|--------------|
+| README.md | 2024-02-20 | 15 | package.json, src/index.ts |
+
+### Aging (6-10 commits behind)
+| File | Last Updated | Commits Behind | Related Code |
+|------|--------------|----------------|--------------|
+| CONTRIBUTING.md | 2024-03-01 | 8 | .github/*, scripts/* |
+
+### Summary
+- Critical: 1 file
+- Stale: 1 file
+- Aging: 1 file
+- Fresh: 12 files
+- Total documentation files: 15
+```
+
+## Options
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--threshold <n>` | Commits behind to flag as stale | 10 |
+| `--days` | Use days instead of commits | false |
+| `--path <dir>` | Scan specific directory | Project root |
+| `--doc-pattern <glob>` | Pattern for doc files | `**/*.md,**/README*` |
+| `--ignore <glob>` | Ignore specific docs | `CHANGELOG.md,LICENSE` |
+| `--show-fresh` | Include fresh docs in output | false |
+| `--format <fmt>` | Output format (table, json) | table |
+
+## Relationship Detection
+
+How docs are mapped to code:
+
+1. **Same Directory**
+   - `src/api/README.md` relates to `src/api/**/*`
+
+2. **Name Matching**
+   - `docs/auth.md` relates to `**/auth.*`, `**/auth/**`
+
+3. **Explicit Links**
+   - Parse `[link](path)` in docs to find related files
+
+4. **Import Analysis**
+   - Track which modules are referenced in code examples
+
+## Configuration
+
+Create `.doc-guardian.yml` to customize mappings:
+```yaml
+stale-docs:
+  threshold: 10
+  mappings:
+    - doc: docs/deployment.md
+      code:
+        - Dockerfile
+        - docker-compose.yml
+        - .github/workflows/deploy.yml
+    - doc: ARCHITECTURE.md
+      code:
+        - src/**/*
+  ignore:
+    - CHANGELOG.md
+    - LICENSE
+    - vendor/**
+```
+
+## Example Usage
+
+```
+/stale-docs
+/stale-docs --threshold 5
+/stale-docs --days --threshold 30
+/stale-docs --path docs/ --show-fresh
+```
+
+## Integration with doc-audit
+
+`/stale-docs` focuses specifically on commit-based staleness, while `/doc-audit` checks content accuracy. Use both for comprehensive documentation health:
+
+```
+/doc-audit      # Check for broken references and content drift
+/stale-docs     # Check for files that may need review
+```
+
+## Exit Codes
+
+- 0: No critical or stale documentation
+- 1: Stale documentation found (useful for CI)
+- 2: Critical documentation found

+# Branching Strategy
+
+## Overview
+
+This document defines the branching strategy used by git-flow to manage code changes across environments. The strategy ensures:
+
+- **Stability**: Production code is always release-ready
+- **Isolation**: Features are developed in isolation without affecting others
+- **Traceability**: Clear history of what changed and when
+- **Collaboration**: Multiple developers can work simultaneously without conflicts
+
+The strategy follows a hierarchical promotion model: feature branches merge into development, which promotes to staging for testing, and finally to main for production release.
+
+## Branch Types
+
+### Main Branches
+
+| Branch | Purpose | Stability | Direct Commits |
+|--------|---------|-----------|----------------|
+| `main` | Production releases | Highest | Never |
+| `staging` | Pre-production testing | High | Never |
+| `development` | Active development | Medium | Never |
+
+### Feature Branches
+
+Feature branches are short-lived branches created from `development` for implementing specific changes.
+
+| Prefix | Purpose | Example |
+|--------|---------|---------|
+| `feat/` | New features | `feat/user-authentication` |
+| `fix/` | Bug fixes | `fix/login-timeout-error` |
+| `docs/` | Documentation only | `docs/api-reference` |
+| `refactor/` | Code restructuring | `refactor/auth-module` |
+| `test/` | Test additions/fixes | `test/auth-coverage` |
+| `chore/` | Maintenance tasks | `chore/update-dependencies` |
+
+### Special Branches
+
+| Branch | Purpose | Created From | Merges Into |
+|--------|---------|--------------|-------------|
+| `hotfix/*` | Emergency production fixes | `main` | `main` AND `development` |
+| `release/*` | Release preparation | `development` | `staging` then `main` |
+

+
+## Workflow
+
+### Feature Development
+
+The standard workflow for implementing a new feature or fix:
+
+```mermaid
+gitGraph
+    commit id: "initial"
+    branch development
+    checkout development
+    commit id: "dev-base"
+    branch feat/new-feature
+    checkout feat/new-feature
+    commit id: "implement"
+    commit id: "tests"
+    commit id: "polish"
+    checkout development
+    merge feat/new-feature id: "PR merged"
+    commit id: "other-work"
+```
+
+**Steps:**
+
+1. **Create branch from development**
+   ```bash
+   git checkout development
+   git pull origin development
+   git checkout -b feat/add-user-auth
+   ```
+   Or use git-flow command:
+   ```
+   /branch-start add user authentication
+   ```
+
+2. **Implement changes**
+   - Make commits following conventional commit format
+   - Keep commits atomic and focused
+   - Push regularly to remote
+
+3. **Create Pull Request**
+   - Target: `development`
+   - Include description of changes
+   - Link related issues
+
+4. **Review and merge**
+   - Address review feedback
+   - Squash or rebase as needed
+   - Merge when approved
+
+5. **Cleanup**
+   - Delete feature branch after merge
+   ```
+   /branch-cleanup
+   ```
+
+### Release Promotion
+
+Promoting code from development to production:
+
+```mermaid
+gitGraph
+    commit id: "v1.0.0" tag: "v1.0.0"
+    branch development
+    checkout development
+    commit id: "feat-1"
+    commit id: "feat-2"
+    commit id: "fix-1"
+    branch staging
+    checkout staging
+    commit id: "staging-test"
+    checkout main
+    merge staging id: "v1.1.0" tag: "v1.1.0"
+    checkout development
+    merge main id: "sync"
+```
+
+**Steps:**
+
+1. **Prepare release**
+   - Ensure development is stable
+   - Update version numbers
+   - Update CHANGELOG.md
+
+2. **Promote to staging**
+   ```bash
+   git checkout staging
+   git merge development
+   git push origin staging
+   ```
+
+3. **Test in staging**
+   - Run integration tests
+   - Perform QA validation
+   - Fix any issues (merge fixes to development first, then re-promote)
+
+4. **Promote to main**
+   ```bash
+   git checkout main
+   git merge staging
+   git tag -a v1.1.0 -m "Release v1.1.0"
+   git push origin main --tags
+   ```
+
+5. **Sync development**
+   ```bash
+   git checkout development
+   git merge main
+   git push origin development
+   ```
+
+### Hotfix Handling
+
+Emergency fixes for production issues:
+
+```mermaid
+gitGraph
+    commit id: "v1.0.0" tag: "v1.0.0"
+    branch development
+    checkout development
+    commit id: "ongoing-work"
+    checkout main
+    branch hotfix/critical-bug
+    checkout hotfix/critical-bug
+    commit id: "fix"
+    checkout main
+    merge hotfix/critical-bug id: "v1.0.1" tag: "v1.0.1"
+    checkout development
+    merge main id: "sync-fix"
+```
+
+**Steps:**
+
+1. **Create hotfix branch from main**
+   ```bash
+   git checkout main
+   git pull origin main
+   git checkout -b hotfix/critical-security-fix
+   ```
+
+2. **Implement fix**
+   - Minimal, focused changes only
+   - Include tests for the fix
+   - Follow conventional commit format
+
+3. **Merge to main**
+   ```bash
+   git checkout main
+   git merge hotfix/critical-security-fix
+   git tag -a v1.0.1 -m "Hotfix: critical security fix"
+   git push origin main --tags
+   ```
+
+4. **Merge to development** (critical step)
+   ```bash
+   git checkout development
+   git merge main
+   git push origin development
+   ```
+
+5. **Delete hotfix branch**
+   ```bash
+   git branch -d hotfix/critical-security-fix
+   git push origin --delete hotfix/critical-security-fix
+   ```
+

+## Examples
+
+### Example 1: Adding a New Feature
+
+**Scenario:** Add user password reset functionality
+
+```bash
+# 1. Start from development
+git checkout development
+git pull origin development
+
+# 2. Create feature branch
+git checkout -b feat/password-reset

+- GET /auth/me"
+
+# 3. Push and create PR
+git push -u origin docs/api-authentication
+```
+
+### Example 4: Emergency Hotfix
+
+**Scenario:** Critical security vulnerability in production
+
+```bash
+# 1. Create hotfix from main
+git checkout main
+git pull origin main
+git checkout -b hotfix/sql-injection
+
+# 2. Fix the issue
+git add src/db/queries.ts
+git commit -m "fix(security): sanitize SQL query parameters
+
+CRITICAL: Addresses SQL injection vulnerability in user search.
+All user inputs are now properly parameterized.
+
+CVE: CVE-2024-XXXXX"
+
+# 3. Merge to main with tag

+git push origin main --tags
+
+# 4. Sync to development (IMPORTANT!)
+git checkout development
+git merge main
+git push origin development
+
+# 5. Cleanup
+git branch -d hotfix/sql-injection
+```
+
+### Example 5: Release Promotion
+
+**Scenario:** Release version 2.2.0
+
+```bash
+# 1. Ensure development is ready
+git checkout development
+git pull origin development
+# Run full test suite
+npm test
+
+# 2. Update version and changelog
+# Edit package.json, CHANGELOG.md
+git add package.json CHANGELOG.md
+git commit -m "chore(release): prepare v2.2.0"
+
+# 3. Promote to staging
+git checkout staging
+git merge development
+git push origin staging
+
+# 4. After QA approval, promote to main
+git checkout main
+git merge staging
+git tag -a v2.2.0 -m "Release v2.2.0"
+git push origin main --tags
+
+# 5. Sync development
+git checkout development
+git merge main
+git push origin development
+```
+
+## Configuration
+
+### Environment Variables
+
+Configure the branching strategy via environment variables:
+
+```bash
+# Default base branch for new features
+GIT_DEFAULT_BASE=development
+
+# Protected branches (comma-separated)
+GIT_PROTECTED_BRANCHES=main,master,development,staging,production
+
+# Workflow style
+GIT_WORKFLOW_STYLE=feature-branch
+
+# Auto-delete merged branches
+GIT_AUTO_DELETE_MERGED=true
+```
+
+### Per-Project Configuration
+
+Create `.git-flow.json` in project root:
+
+```json
+{
+  "defaultBase": "development",
+  "protectedBranches": ["main", "staging", "development"],
+  "branchPrefixes": ["feat", "fix", "docs", "refactor", "test", "chore"],
+  "requirePR": {
+    "main": true,
+    "staging": true,
+    "development": false
+  },
+  "squashOnMerge": {
+    "development": true,
+    "staging": false,
+    "main": false
+  }
+}
+```
+
+## Best Practices
+
+### Do
+
+- Keep feature branches short-lived (< 1 week)
+- Rebase feature branches on development regularly
+- Write descriptive commit messages
+- Delete branches after merging
+- Tag all releases on main
+- Always sync development after hotfixes
+
+### Avoid
+
+- Long-lived feature branches
+- Direct commits to protected branches
+- Force pushing to shared branches
+- Merging untested code to staging
+- Skipping the development sync after hotfixes

 ## Configuration
 
+Environment variables can be set in your project's `.env` file or shell environment.
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PR_REVIEW_CONFIDENCE_THRESHOLD` | `0.7` | Minimum confidence score (0.0-1.0) for reporting findings. Findings below this threshold are filtered out to reduce noise. |
+| `PR_REVIEW_AUTO_SUBMIT` | `false` | Automatically submit review to Gitea without confirmation prompt |
+
+### Example Configuration
+
 ```bash
-# Minimum confidence to report (default: 0.5)
+# Project .env file
-PR_REVIEW_CONFIDENCE_THRESHOLD=0.5
+
+# Only show high-confidence findings (MEDIUM and HIGH)
+PR_REVIEW_CONFIDENCE_THRESHOLD=0.7
 
 # Auto-submit review to Gitea (default: false)
 PR_REVIEW_AUTO_SUBMIT=false
 ```
 
+### Confidence Threshold Details
+
+The confidence threshold filters which findings appear in review output:
+
+| Threshold | Effect |
+|-----------|--------|
+| `0.9` | Only definite issues (HIGH confidence) |
+| `0.7` | Likely issues and above (MEDIUM+HIGH) - **recommended** |
+| `0.5` | Include possible concerns (LOW+MEDIUM+HIGH) |
+| `0.3` | Include speculative findings |
+
+Lower thresholds show more findings but may include false positives. Higher thresholds reduce noise but may miss some valid concerns.

+# /pr-diff - Annotated PR Diff Viewer
+
+## Purpose
+
+Display the PR diff with inline annotations from review comments, making it easy to see what feedback has been given alongside the code changes.
+
+## Usage
+
+```
+/pr-diff <pr-number> [--repo owner/repo] [--context <lines>]
+```
+
+### Options
+
+```
+--repo <owner/repo>   Override repository (default: from .env)
+--context <n>         Lines of context around changes (default: 3)
+--no-comments         Show diff without comment annotations
+--file <pattern>      Filter to specific files (glob pattern)
+```
+
+## Behavior
+
+### Step 1: Fetch PR Data
+
+Using Gitea MCP tools:
+1. `get_pr_diff` - Unified diff of all changes
+2. `get_pr_comments` - All review comments on the PR
+
+### Step 2: Parse and Annotate
+
+Parse the diff and overlay comments at their respective file/line positions:
