fix(marketplace): remove integrates_with field (schema violation)

Claude Code's marketplace schema does not support custom fields.
The `integrates_with` field on data-platform and viz-platform caused:
"Invalid schema: plugins.9: Unrecognized key: integrates_with"

This reverts the schema extension while keeping the validate_workflow_integration
MCP tool functional (it reads from plugin.json files directly, not marketplace.json).

+## [5.7.1] - 2026-02-02
+
+### Added
+- **contract-validator**: New `validate_workflow_integration` MCP tool — validates domain plugins expose required advisory interfaces (gate command, review command, advisory agent)
+- **contract-validator**: New `MISSING_INTEGRATION` issue type for workflow integration validation
+
+### Fixed
+- `scripts/setup.sh` banner version updated from v5.1.0 to v5.7.1
+
+### Reverted
+- **marketplace.json**: Removed `integrates_with` field — Claude Code schema does not support custom plugin fields (causes marketplace load failure)
+
+---
+
+## [5.7.0] - 2026-02-02
+
+### Added
+- **data-platform**: New `data-advisor` agent for data integrity, schema, and dbt compliance validation

+- **data-platform**: New `/data-gate` command for binary pass/fail data integrity gates (projman integration)
+- **data-platform**: New `/data-review` command for comprehensive data integrity audits
+
+### Changed
+- Domain Advisory Pattern now fully operational for both Viz and Data domains
+- projman orchestrator `Domain/Data` gates now resolve to live `/data-gate` command (previously fell through to "gate unavailable" warning)
+
+---
+
+## [5.6.0] - 2026-02-01
+
+### Added
+- **Domain Advisory Pattern**: Cross-plugin integration enabling projman to consult domain-specific plugins during sprint lifecycle
+- **projman**: New `domain-consultation.md` skill for domain detection and gate protocols
+- **viz-platform**: New `design-reviewer` agent for design system compliance auditing

+## Domain Advisory Pattern
+
+The marketplace supports cross-plugin domain advisory integration:
+
+- **Domain Detection**: projman automatically detects when issues involve specialized domains (frontend/viz, data engineering)
+- **Acceptance Criteria**: Domain-specific acceptance criteria are added to issues during planning
+- **Execution Gates**: Domain validation gates (`/design-gate`, `/data-gate`) run before issue completion
+- **Extensible**: New domains can be added by creating advisory agents and gate commands
+
+**Current Domains:**
+| Domain | Plugin | Gate Command |
+|--------|--------|--------------|
+| Visualization | viz-platform | `/design-gate` |
+| Data | data-platform | `/data-gate` |

+
+## Audit Workflow
+
+### 1. Receive Target Path
+
+Accept file or directory path from command invocation.
+
+### 2. Determine Scope
+
+Analyze target to identify what type of data work is present:
+
+| Pattern | Type | Checks to Run |
+|---------|------|---------------|
+| `dbt_project.yml` present | dbt project | Full dbt validation |
+| `*.sql` files in dbt path | dbt models | Model compilation, lineage |
+| `*.py` with `pg_query`/`pg_execute` | Database operations | Schema validation |
+| `schema.yml` files | dbt schemas | Schema drift detection |
+| Migration files (`*_migration.sql`) | Schema changes | Full PostgreSQL + dbt checks |
+
+### 3. Run Database Checks (if applicable)
+
+```
+1. pg_connect → verify database reachable
+   If fails: WARN, continue with file-based checks
+
+2. pg_tables → verify expected tables exist
+   If missing: FAIL
+
+3. pg_columns on affected tables → verify types
+   If mismatch: FAIL
+```
+
+### 4. Run dbt Checks (if applicable)
+
+```
+1. dbt_parse → validate project
+   If fails: FAIL immediately (project broken)
+
+2. dbt_ls → catalog all resources
+   Record models, tests, sources
+
+3. dbt_lineage on target models → check integrity
+   Orphaned refs: FAIL
+
+4. dbt_compile on target models → verify SQL
+   Compilation errors: FAIL
+
+5. dbt_test --select <targets> → run tests
+   Test failures: FAIL
+
+6. Cross-reference tests → models without tests
+   Missing tests: WARN
+```
+
+### 5. Run PostGIS Checks (if applicable)
+
+```
+1. st_tables → list spatial tables
+   If none found: skip PostGIS checks
+
+2. st_srid → verify SRID correct
+   Unexpected SRID: FAIL
+
+3. st_geometry_type → verify expected types
+   Wrong type: WARN
+
+4. st_extent → sanity check bounding box
+   Unreasonable extent: FAIL
+```
+
+### 6. Scan Python Code (manual patterns)
+
+For Python files with database operations:
+
+| Pattern | Issue | Severity |
+|---------|-------|----------|
+| `f"SELECT * FROM {table}"` | SQL injection risk | WARN |
+| `f"INSERT INTO {table}"` | Unparameterized mutation | WARN |
+| `pg_execute` without WHERE in DELETE/UPDATE | Dangerous mutation | WARN |
+| Hardcoded connection strings | Credential exposure | WARN |
+
+### 7. Generate Report
+
+Output format depends on operating mode (see templates in `skills/data-integrity-audit.md`).
+
+## Report Formats
+
+### Gate Mode Output
+
+**PASS:**

+## Severity Definitions
+
+| Level | Criteria | Action Required |
+|-------|----------|-----------------|
+| **FAIL** | dbt parse/compile fails, missing tables/columns, type mismatches, broken lineage, invalid SRID | Must fix before completion |
+| **WARN** | Missing tests, hardcoded SQL, schema drift, orphaned models | Should fix |
+| **INFO** | Documentation gaps, optimization opportunities | Consider for improvement |
+
+## Error Handling
+
+| Error | Response |
+|-------|----------|
+| Database not reachable | WARN: "PostgreSQL unavailable, skipping schema checks" - continue |
+| No dbt_project.yml | Skip dbt checks silently - not an error |
+| No PostGIS tables | Skip PostGIS checks silently - not an error |
+| MCP tool fails | WARN: "Tool {name} failed: {error}" - continue with remaining |
+| Empty path | PASS: "No data artifacts found in target path" |
+| Invalid path | Error: "Path not found: {path}" |
+
+## Integration with projman
+
+When called as a domain gate by projman orchestrator:
+
+1. Receive path from orchestrator (changed files for the issue)
+2. Determine what type of data work changed
+3. Run audit in gate mode
+4. Return structured result:
+   ```
+   Gate: data
+   Status: PASS | FAIL
+   Blocking: N issues
+   Summary: Brief description
+   ```
+5. Orchestrator decides whether to proceed based on gate status
+
+## Example Interactions
+
+**User**: `/data-review dbt/models/staging/`
+**Agent**:
+1. Scans all .sql files in staging/
+2. Runs dbt_parse to validate project
+3. Runs dbt_compile on each model
+4. Checks lineage for orphaned refs
+5. Cross-references test coverage
+6. Returns detailed report
+
+**User**: `/data-gate portfolio_app/toronto/`
+**Agent**:
+1. Scans for Python files with pg_query/pg_execute
+2. Checks if referenced tables exist
+3. Validates column types
+4. Returns PASS if clean, FAIL with blocking issues if not
+5. Compact output for automation
+
+## Communication Style
+
+Technical and precise. Report findings with exact locations, specific violations, and actionable fixes:
+
+- "Table `census_demographics` column `population` is `varchar(50)` in PostgreSQL but referenced as `integer` in `stg_census.sql` line 14. This will cause a runtime cast error."
+- "Model `dim_neighbourhoods` has no `unique` test on `neighbourhood_id`. Add to `schema.yml` to prevent duplicates."
+- "Spatial extent for `toronto_boundaries` shows global coordinates (-180 to 180). Expected Toronto bbox (~-79.6 to -79.1 longitude). Likely missing ST_Transform or wrong SRID on import."

+# /data-gate
+
+Binary pass/fail validation for data integrity compliance. Used by projman orchestrator during sprint execution to gate issue completion.
+
+## Usage
+
+```
+/data-gate <path>
+```
+
+**Examples:**
+```
+/data-gate ./dbt/models/staging/
+/data-gate ./portfolio_app/toronto/parsers/
+/data-gate ./dbt/
+```
+
+## What It Does
+
+1. **Activates** the `data-advisor` agent in gate mode
+2. **Loads** the `skills/data-integrity-audit.md` skill
+3. **Determines scope** from target path:
+   - dbt project directory: full dbt validation (parse, compile, test, lineage)
+   - Python files with database operations: schema validation
+   - SQL files: dbt model validation
+   - Mixed: all applicable checks
+4. **Checks only FAIL-level violations:**
+   - dbt parse failures (project broken)
+   - dbt compilation errors (SQL invalid)
+   - Missing tables/columns referenced in code
+   - Data type mismatches that cause runtime errors
+   - Broken lineage (orphaned model references)
+   - PostGIS SRID mismatches
+5. **Returns binary result:**
+   - `PASS` - No blocking violations found
+   - `FAIL` - One or more blocking violations
+
+## Output
+
+### On PASS
+```
+DATA GATE: PASS
+No blocking data integrity violations found.
+```
+
+### On FAIL
+```
+DATA GATE: FAIL
+
+Blocking Issues (2):
+1. dbt/models/staging/stg_census.sql - Compilation error: column 'census_yr' not found
+   Fix: Column was renamed to 'census_year' in source table. Update model.
+
+2. portfolio_app/toronto/loaders/census.py:67 - References table 'census_raw' which does not exist
+   Fix: Table was renamed to 'census_demographics' in migration 003.
+
+Run /data-review for full audit report.
+```
+
+## Integration with projman
+
+This command is automatically invoked by the projman orchestrator when:
+
+1. An issue has the `Domain/Data` label
+2. The orchestrator is about to mark the issue as complete
+3. The orchestrator passes the path of changed files
+
+**Gate behavior:**
+- PASS: Issue can be marked complete
+- FAIL: Issue stays open, blocker comment added with failure details
+
+## Differences from /data-review
+
+| Aspect | /data-gate | /data-review |
+|--------|------------|--------------|
+| Output | Binary PASS/FAIL | Detailed report with all severities |
+| Severity | FAIL only | FAIL + WARN + INFO |
+| Purpose | Automation gate | Human review |
+| Verbosity | Minimal | Comprehensive |
+| Speed | Skips INFO checks | Full scan |
+
+## When to Use
+
+- **Sprint execution**: Automatic quality gates via projman
+- **CI/CD pipelines**: Automated data integrity checks
+- **Quick validation**: Fast pass/fail without full report
+- **Pre-merge checks**: Verify data changes before integration
+
+For detailed findings including warnings and suggestions, use `/data-review` instead.
+
+## Requirements
+

+description: Rules and patterns for auditing data integrity, schema validity, and dbt compliance
+---
+
+# Data Integrity Audit
+
+## Purpose
+
+Defines what "data valid" means for the data-platform domain. This skill is loaded by the `data-advisor` agent for both review and gate modes during sprint execution and standalone audits.
+
+---
+
+## What to Check
+
+| Check Category | What It Validates | MCP Tools Used |
+|----------------|-------------------|----------------|
+| **Schema Validity** | Tables exist, columns have correct types, constraints present, no orphaned columns | `pg_tables`, `pg_columns`, `pg_schemas` |
+| **dbt Project Health** | Project parses without errors, models compile, tests defined for critical models | `dbt_parse`, `dbt_compile`, `dbt_test`, `dbt_ls` |
+| **Lineage Integrity** | No orphaned models (referenced but missing), no circular dependencies, upstream sources exist | `dbt_lineage`, `dbt_ls` |
+| **Data Type Consistency** | DataFrame dtypes match expected schema, no silent type coercion, date formats consistent | `describe`, `head`, `pg_columns` |
+| **PostGIS Compliance** | Spatial tables have correct SRID, geometry types match expectations, extent is reasonable | `st_tables`, `st_geometry_type`, `st_srid`, `st_extent` |
+| **Query Safety** | SELECT queries used for reads (not raw SQL for mutations), parameterized patterns | Code review - manual pattern check |
+
+---
+
+## Common Violations
+
+### FAIL-Level Violations (Block Gate)
+
+| Violation | Detection Method | Example |
+|-----------|-----------------|---------|
+| dbt parse failure | `dbt_parse` returns error | Project YAML invalid, missing ref targets |
+| dbt compilation error | `dbt_compile` fails | SQL syntax error, undefined column reference |
+| Missing table/column | `pg_tables`, `pg_columns` lookup | Code references `census_raw` but table doesn't exist |
+| Type mismatch | Compare `pg_columns` vs dbt schema | Column is `varchar` in DB but model expects `integer` |
+| Broken lineage | `dbt_lineage` shows orphaned refs | Model references `stg_old_format` which doesn't exist |
+| PostGIS SRID mismatch | `st_srid` returns unexpected value | Geometry column has SRID 0 instead of 4326 |
+| Unreasonable spatial extent | `st_extent` returns global bbox | Toronto data shows coordinates in China |
+
+### WARN-Level Violations (Report, Don't Block)
+
+| Violation | Detection Method | Example |
+|-----------|-----------------|---------|
+| Missing dbt tests | `dbt_ls` shows model without test | `dim_customers` has no `unique` test on `customer_id` |
+| Undocumented columns | dbt schema.yml missing descriptions | Model columns have no documentation |
+| Schema drift | `pg_columns` vs dbt schema.yml | Column exists in DB but not in dbt YAML |
+| Hardcoded SQL | Scan Python for string concatenation | `f"SELECT * FROM {table}"` without parameterization |
+| Orphaned model | `dbt_lineage` shows no downstream | `stg_legacy` has no consumers and no exposure |
+
+### INFO-Level Violations (Suggestions Only)
+
+| Violation | Detection Method | Example |
+|-----------|-----------------|---------|
+| Missing indexes | Query pattern suggests need | Frequent filter on non-indexed column |
+| Documentation gaps | dbt docs incomplete | Missing model description |
+| Unused models | `dbt_ls` vs actual queries | Model exists but never selected |
+| Optimization opportunity | `describe` shows data patterns | Column has low cardinality, could be enum |
+
+---
+
+## Severity Classification
+
+| Severity | When to Apply | Gate Behavior |
+|----------|--------------|---------------|
+| **FAIL** | Broken lineage, models that won't compile, missing tables/columns, data type mismatches that cause runtime errors, invalid SRID | Blocks issue completion |
+| **WARN** | Missing dbt tests, undocumented columns, schema drift, hardcoded SQL, orphaned models | Does NOT block gate, included in review report |
+| **INFO** | Optimization opportunities, documentation gaps, unused models | Review report only |
+
+### Severity Decision Tree
+
+```
+Is the dbt project broken (parse/compile fails)?
+  YES -> FAIL
+  NO -> Does code reference non-existent tables/columns?
+    YES -> FAIL
+    NO -> Would this cause a runtime error?
+      YES -> FAIL
+      NO -> Does it violate data quality standards?

+
+## Scanning Strategy
+
+### For dbt Projects
+
+1. **Parse validation** (ALWAYS FIRST)
+   ```
+   dbt_parse → if fails, immediate FAIL (project is broken)
+   ```
+
+2. **Catalog resources**
+   ```
+   dbt_ls → list all models, tests, sources, exposures
+   ```
+
+3. **Lineage check**
+   ```
+   dbt_lineage on changed models → check upstream/downstream integrity
+   ```
+
+4. **Compilation check**
+   ```
+   dbt_compile on changed models → verify SQL renders correctly
+   ```
+
+5. **Test execution**
+   ```
+   dbt_test --select <changed_models> → verify tests pass
+   ```
+
+6. **Test coverage audit**
+   ```
+   Cross-reference dbt_ls tests against model list → flag models without tests (WARN)
+   ```
+
+### For PostgreSQL Schema Changes
+
+1. **Table verification**
+   ```
+   pg_tables → verify expected tables exist
+   ```
+
+2. **Column validation**
+   ```
+   pg_columns on affected tables → verify types match expectations
+   ```
+
+3. **Schema comparison**
+   ```
+   Compare pg_columns output against dbt schema.yml → flag drift
+   ```
+
+### For PostGIS/Spatial Data
+
+1. **Spatial table scan**
+   ```
+   st_tables → list tables with geometry columns
+   ```
+
+2. **SRID validation**
+   ```
+   st_srid → verify SRID is correct for expected region
+   Expected: 4326 (WGS84) for GPS data, local projections for regional data
+   ```
+
+3. **Geometry type check**
+   ```
+   st_geometry_type → verify expected types (Point, Polygon, etc.)
+   ```
+
+4. **Extent sanity check**
+   ```
+   st_extent → verify bounding box is reasonable for expected region
+   Toronto data should be ~(-79.6 to -79.1, 43.6 to 43.9)
+   ```
+
+### For DataFrame/pandas Operations
+
+1. **Data quality check**
+   ```
+   describe → check for unexpected nulls, type issues, outliers
+   ```
+
+2. **Structure verification**
+   ```
+   head → verify data structure matches expectations
+   ```
+
+3. **Memory management**
+   ```
+   list_data → verify no stale DataFrames from previous failed runs
+   ```
+
+### For Python Code (Manual Scan)
+
+1. **SQL injection patterns**
+   - Scan for f-strings with table/column names
+   - Check for string concatenation in queries
+   - Look for `.format()` calls with SQL
+
+2. **Mutation safety**
+   - `pg_execute` usage should be intentional, not accidental
+   - Verify DELETE/UPDATE have WHERE clauses
+
+3. **Credential exposure**
+   - No hardcoded connection strings
+   - No credentials in code (check for `.env` usage)

+- `**/__pycache__/**` - Compiled files
+- `**/fixtures/**` - Test fixtures
+- `**/.scratch/**` - Temporary working files
+- Files with `# noqa: data-audit` comment
+- Migration files marked as historical

+
+## Error Handling
+
+| Scenario | Behavior |
+|----------|----------|
+| Database not reachable (`pg_connect` fails) | WARN, skip PostgreSQL checks, continue with file-based |
+| dbt not configured (no `dbt_project.yml`) | Skip dbt checks entirely, not an error |
+| No PostGIS tables found | Skip PostGIS checks, not an error |
+| MCP tool call fails | Report as WARN with tool name, continue with remaining checks |
+| No data files in scanned path | Report "No data artifacts found" - PASS (nothing to fail) |
+| Empty directory | Report "No files found in path" - PASS |
+

+## Integration Notes
+
+### projman Orchestrator
+
+When called as a domain gate:
+1. Orchestrator detects `Domain/Data` label on issue
+2. Orchestrator identifies changed files
+3. Orchestrator invokes `/data-gate <path>`
+4. Agent runs gate mode scan
+5. Returns PASS/FAIL to orchestrator
+6. Orchestrator decides whether to complete issue
+
+### Standalone Usage
+
+For manual audits:
+1. User runs `/data-review <path>`
+2. Agent runs full review mode scan
+3. Returns detailed report with all severity levels

+description: Cross-plugin domain consultation for specialized planning and validation
+---
+
+# Domain Consultation
+
+## Purpose
+
+Enables projman agents to detect domain-specific work and consult specialized plugins for expert validation during planning and execution phases. This skill is the backbone of the Domain Advisory Pattern.
+
+---
+
+## When to Use
+
+| Agent | Phase | Action |
+|-------|-------|--------|
+| Planner | After task sizing, before issue creation | Detect domains, add acceptance criteria |
+| Orchestrator | Before marking issue complete | Run domain gates, block if violations |
+| Code Reviewer | During review | Include domain compliance in findings |
+
+---
+
+## Domain Detection Rules
+
+| Signal Type | Detection Pattern | Domain Plugin | Action |
+|-------------|-------------------|---------------|--------|
+| Label-based | `Component/Frontend`, `Component/UI` | viz-platform | Add design system criteria, apply `Domain/Viz` |
+| Content-based | Keywords: DMC, Dash, layout, theme, component, dashboard, chart, responsive, color, UI, frontend, Plotly | viz-platform | Same as above |
+| Label-based | `Component/Database`, `Component/Data` | data-platform | Add data validation criteria, apply `Domain/Data` |
+| Content-based | Keywords: schema, migration, pipeline, dbt, table, column, query, PostgreSQL, lineage, data model | data-platform | Same as above |
+| Both signals | Frontend + Data signals present | Both plugins | Apply both sets of criteria |
+
+---
+
+## Planning Protocol
+
+When creating issues, the planner MUST:
+
+1. **Analyze each issue** for domain signals (check labels AND scan description for keywords)
+
+2. **For Domain/Viz issues**, append this acceptance criteria block:
+   ```markdown
+   ## Design System Compliance
+   - [ ] All DMC components validated against registry
+   - [ ] Theme tokens used (no hardcoded colors/sizes)
+   - [ ] Accessibility check passed (WCAG contrast)
+   - [ ] Responsive breakpoints verified
+   ```
+
+3. **For Domain/Data issues**, append this acceptance criteria block:
+   ```markdown
+   ## Data Integrity
+   - [ ] Schema changes validated
+   - [ ] dbt tests pass
+   - [ ] Lineage intact (no orphaned models)
+   - [ ] Data types verified
+   ```
+
+4. **Apply the corresponding `Domain/*` label** to route the issue through gates
+
+5. **Document in planning summary** which issues have domain gates active
+
+---
+
+## Execution Gate Protocol
+
+Before marking any issue as complete, the orchestrator MUST:
+
+1. **Check issue labels** for `Domain/*` labels
+
+2. **If `Domain/Viz` label present:**
+   - Identify files changed by this issue
+   - Invoke `/design-gate <path-to-changed-files>`
+   - Gate PASS → proceed to mark issue complete
+   - Gate FAIL → add comment to issue with failure details, keep issue open
+
+3. **If `Domain/Data` label present:**
+   - Identify files changed by this issue
+   - Invoke `/data-gate <path-to-changed-files>`
+   - Gate PASS → proceed to mark issue complete
+   - Gate FAIL → add comment to issue with failure details, keep issue open
+
+4. **If gate command unavailable** (MCP server not running):
+   - Warn user: "Domain gate unavailable - proceeding without validation"
+   - Proceed with completion (non-blocking degradation)
+   - Do NOT silently skip - always inform user
+
+---
+
+## Review Protocol
+
+During code review, the code reviewer SHOULD:
+
+1. After completing standard code quality and security checks, check for `Domain/*` labels
+
+2. **If Domain/Viz:** Include "Design System Compliance" section in review report
+   - Reference `/design-review` findings if available
+   - Check for hardcoded colors, invalid props, accessibility issues
+
+3. **If Domain/Data:** Include "Data Integrity" section in review report
+   - Reference `/data-gate` findings if available
+   - Check for schema validity, lineage integrity
+
+---
+
+## Extensibility
+
+To add a new domain (e.g., `Domain/Infra` for cmdb-assistant):
+
+1. **In domain plugin:** Create advisory agent + gate command
+   - Agent: `agents/infra-advisor.md`
+   - Gate command: `commands/infra-gate.md`
+   - Audit skill: `skills/infra-audit.md`
+
+2. **In this skill:** Add detection rules to the Detection Rules table above
+   - Define label-based signals (e.g., `Component/Infrastructure`)
+   - Define content-based keywords (e.g., "server", "network", "NetBox")
+
+3. **In label taxonomy:** Add `Domain/Infra` label with appropriate color
+   - Update `plugins/projman/skills/label-taxonomy/labels-reference.md`
+
+4. **No changes needed** to planner.md or orchestrator.md agent files
+   - They read this skill dynamically
+   - Detection rules table is the single source of truth
+
+This pattern ensures domain expertise stays in domain plugins while projman orchestrates when to ask.

+
+Triggered by `/design-review <path>`
+
+**Characteristics:**
+- Produces detailed report with all findings
+- Groups findings by severity (FAIL/WARN/INFO)
+- Includes actionable recommendations with code fixes
+- Does NOT block - informational only
+- Shows theme compliance percentage
+
+### Gate Mode
+
+Triggered by `/design-gate <path>` or projman orchestrator domain gate
+
+**Characteristics:**
+- Binary PASS/FAIL output
+- Only reports FAIL-level issues
+- Returns exit status for automation integration
+- Blocks completion on FAIL
+- Compact output for CI/CD pipelines
+
+## Audit Workflow
+
+### 1. Receive Target Path
+Accept file or directory path from command invocation.
+
+### 2. Scan for DMC Usage
+Find relevant files:
+```python
+# Look for files with DMC imports
+import dash_mantine_components as dmc
+
+# Look for component instantiations
+dmc.Button(...)
+dmc.Card(...)
+```
+
+### 3. Component Validation
+For each DMC component found:
+
+1. Extract component name and props from code
+2. Call `list_components` to verify component exists in registry
+3. Call `get_component_props` to get valid prop schema
+4. Compare used props against schema
+5. **FAIL**: Invalid props, unknown components
+6. **WARN**: Deprecated patterns, React-style props
+
+### 4. Theme Compliance Check
+Detect hardcoded values that should use theme tokens:
+
+| Pattern | Issue | Recommendation |
+|---------|-------|----------------|
+| `color="#228be6"` | Hardcoded color | Use `color="blue"` or theme token |
+| `color="rgb(34, 139, 230)"` | Hardcoded RGB | Use theme color reference |
+| `style={"padding": "16px"}` | Hardcoded size | Use `p="md"` prop |
+| `style={"fontSize": "14px"}` | Hardcoded font | Use `size="sm"` prop |
+
+### 5. Accessibility Validation
+Check accessibility compliance:
+
+1. Call `accessibility_validate_colors` on detected color pairs
+2. Check color contrast ratios (min 4.5:1 for AA)
+3. Verify interactive components have accessible labels
+4. Flag missing aria-labels on buttons/links
+
+### 6. Generate Report
+Output format depends on operating mode.

+| React prop pattern | `className` | Use Dash equivalents |
+
+### INFO-Level Issues
+
+| Issue | Pattern | Suggestion |
+|-------|---------|------------|
+| Generic container | `dmc.Box` for cards | Use `dmc.Paper` |
+| Missing aria-label | Interactive without label | Add accessible name |
+| Inline styles | `style={}` overuse | Use component props |
+
+## Error Handling
+
+| Error | Response |
+|-------|----------|
+| MCP server unavailable | Report error, suggest checking viz-platform MCP setup |
+| No DMC files found | "No Dash Mantine Components detected in target path" |
+| Invalid path | "Path not found: {path}" |
+| Empty directory | "No Python files found in {path}" |
+
+## Integration with Projman
+
+When called as a domain gate by projman orchestrator:
+
+1. Receive path from orchestrator
+2. Run audit in gate mode
+3. Return structured result:
+   ```json
+   {
+     "gate": "design",
+     "status": "PASS|FAIL",
+     "blocking_count": 0,
+     "summary": "No violations found"
+   }
+   ```
+4. Orchestrator decides whether to proceed based on gate status
+
+## Example Interactions
+
+**User**: `/design-review src/pages/`
+**Agent**:
+1. Scans all .py files in src/pages/
+2. Identifies DMC component usage
+3. Validates each component with MCP tools
+4. Checks theme token usage
+5. Runs accessibility validation
+6. Returns full review report
+
+**User**: `/design-gate src/`
+**Agent**:
+1. Scans all .py files
+2. Identifies FAIL-level issues only
+3. Returns PASS if clean, FAIL with blocking issues if not
+4. Compact output for pipeline integration

+    required: true
+---
+
+# /design-gate
+
+Binary pass/fail validation for design system compliance. Used by projman orchestrator during sprint execution to gate issue completion.
+
+## Usage
+
+```
+/design-gate <path>
+```
+
+**Examples:**
+```
+/design-gate ./app/pages/dashboard.py
+/design-gate ./app/components/
+```
+
+## What It Does
+
+1. **Activates** the `design-reviewer` agent in gate mode
+2. **Loads** the `skills/design-system-audit.md` skill
+3. **Scans** target path for DMC usage
+4. **Checks only for FAIL-level violations:**
+   - Invalid component props
+   - Non-existent components
+   - Missing required props
+   - Deprecated components
+5. **Returns binary result:**
+   - `PASS` - No blocking violations found
+   - `FAIL` - One or more blocking violations
+
+## Output
+
+### On PASS
+```
+DESIGN GATE: PASS
+No blocking design system violations found.
+```
+
+### On FAIL
+```
+DESIGN GATE: FAIL
+
+Blocking Issues (2):
+1. app/pages/home.py:45 - Invalid prop 'onclick' on dmc.Button
+   Fix: Use 'n_clicks' for click handling
+
+2. app/components/nav.py:12 - Component 'dmc.Navbar' not found
+   Fix: Use 'dmc.AppShell.Navbar' (DMC v0.14+)
+
+Run /design-review for full audit report.
+```
+
+## Integration with projman
+
+This command is automatically invoked by the projman orchestrator when:
+
+1. An issue has the `Domain/Viz` label
+2. The orchestrator is about to mark the issue as complete
+3. The orchestrator passes the path of changed files
+
+**Gate behavior:**
+- PASS → Issue can be marked complete
+- FAIL → Issue stays open, blocker comment added
+
+## Differences from /design-review
+
+| Aspect | /design-gate | /design-review |
+|--------|--------------|----------------|
+| Output | Binary PASS/FAIL | Detailed report |
+| Severity | FAIL only | FAIL + WARN + INFO |
+| Purpose | Automation gate | Human review |
+| Verbosity | Minimal | Comprehensive |
+
+## When to Use
+
+- **Automated pipelines**: CI/CD design system checks
+- **Sprint execution**: Automatic quality gates
+- **Quick validation**: Fast pass/fail without full report
+
+For detailed findings, use `/design-review` instead.
+
+## Requirements
+
+- viz-platform MCP server must be running
+- Target path must exist

+# /design-review
+
+Scans target path for Dash Mantine Components usage and validates against design system standards.
+
+## Usage
+
+```
+/design-review <path>
+```
+
+**Examples:**
+```
+/design-review ./app/pages/

+
+## What It Does
+
+1. **Activates** the `design-reviewer` agent in review mode
+2. **Loads** the `skills/design-system-audit.md` skill
+3. **Scans** target path for:
+   - Python files with DMC imports
+   - Component instantiations and their props
+   - Style dictionaries and color values
+   - Accessibility attributes
+4. **Validates** against:
+   - DMC component registry (valid components and props)
+   - Theme token usage (no hardcoded colors/sizes)
+   - Accessibility standards (contrast, ARIA labels)
+5. **Produces** detailed report grouped by severity
+
+## Output
+
+Generates a comprehensive audit report with:
+
+- **FAIL**: Invalid props, deprecated components, missing required props
+- **WARN**: Hardcoded colors/sizes, missing accessibility attributes
+- **INFO**: Optimization suggestions, consistency recommendations
+
+Each finding includes:
+- File path and line number
+- Description of the issue
+- Recommended fix
+

+# Design System Audit
+
+## Purpose
+
+Defines what to check, how to classify violations, and common patterns for design system compliance auditing of Dash Mantine Components (DMC) code.
+
+---
+
+## What to Check
+
+### 1. Component Prop Validity
+
+| Check | Tool | Severity |
+|-------|------|----------|
+| Invalid prop names (typos) | `validate_component` | FAIL |
+| Invalid prop values | `validate_component` | FAIL |
+| Missing required props | `validate_component` | FAIL |
+| Deprecated props | `get_component_props` | WARN |
+| Unknown props | `validate_component` | WARN |
+
+### 2. Theme Token Usage

+| Missing theme provider | AST analysis | FAIL |
+
+**Allowed exceptions:**
+- Colors in theme definition files
+- Test/fixture files
+- Comments and documentation
+
+### 3. Accessibility Compliance
+
+| Check | Tool | Severity |
+|-------|------|----------|
+| Color contrast ratio < 4.5:1 (AA) | `accessibility_validate_colors` | WARN |
+| Color contrast ratio < 3:1 (large text) | `accessibility_validate_colors` | WARN |
+| Missing aria-label on interactive | Manual scan | WARN |
+| Color-only information | `accessibility_validate_theme` | WARN |
+| Focus indicator missing | Manual scan | INFO |
+
+### 4. Responsive Design
+
+| Check | Detection | Severity |
+|-------|-----------|----------|
+| Fixed pixel widths > 600px | Regex `width=\d{3,}` | INFO |
+| Missing breakpoint handling | No `visibleFrom`/`hiddenFrom` | INFO |
+| Non-responsive layout | Fixed Grid columns | INFO |
+
+---
+
+## Common Violations
+
+### FAIL-Level Violations
+
+```python
+# Invalid prop name (typo)
+dmc.Button(colour="blue")  # Should be 'color'
+
+# Invalid enum value
+dmc.Button(size="large")   # Should be 'lg'
+
+# Missing required prop
+dmc.Select(data=[...])     # Missing 'id' for callbacks
+
+# Invalid component name
+dmc.Buttons(...)           # Should be 'Button'
+
+# Wrong case
+dmc.Button(fullwidth=True) # Should be 'fullWidth'
+
+# React patterns in Dash
+dmc.Button(onClick=fn)     # Should use 'id' + callback
+```
+
+### WARN-Level Violations
+
+```python
+# Hardcoded colors
+dmc.Text(color="#ff0000")           # Use theme token
+dmc.Button(style={"color": "red"})  # Use theme token
+
+# Hardcoded font size
+dmc.Text(style={"fontSize": "14px"})  # Use 'size' prop
+
+# Poor contrast
+dmc.Text(color="gray")  # Check contrast ratio
+
+# Inline styles for colors
+dmc.Container(style={"backgroundColor": "#f0f0f0"})
+
+# Deprecated patterns
+dmc.Button(variant="subtle")  # Check if still supported
+```
+
+### INFO-Level Violations
+
+```python
+# Fixed widths
+dmc.Container(w=800)  # Consider responsive
+
+# Missing responsive handling
+dmc.Grid.Col(span=6)  # Consider span={{ base: 12, md: 6 }}
+
+# Optimization opportunity
+dmc.Stack([dmc.Text(...) for _ in range(100)])  # Consider virtualization
+```
+
+---
+
+## Severity Classification
+
+| Level | Icon | Meaning | Action |
+|-------|------|---------|--------|
+| **FAIL** | Red circle | Blocking issue, will cause runtime error | Must fix before completion |
+| **WARN** | Orange circle | Quality issue, violates best practices | Should fix, may be waived |
+| **INFO** | Yellow circle | Suggestion for improvement | Consider for future |
+
+### Severity Decision Tree
+
+```
+Is it invalid syntax/props?
+  YES -> FAIL
+  NO -> Does it violate accessibility standards?
+    YES -> WARN
+    NO -> Does it use hardcoded styles?
+      YES -> WARN
+      NO -> Is it a best practice suggestion?
+        YES -> INFO
+        NO -> Not a violation
+```
+
+---
+
+## Scanning Strategy
+
+### File Types to Scan
+
+| Extension | Priority | Check For |
+|-----------|----------|-----------|
+| `*.py` | High | DMC component usage |
+| `*.dash.py` | High | Layout definitions |
+| `theme*.py` | High | Theme configuration |
+| `layout*.py` | High | Layout structure |
+| `components/*.py` | High | Custom components |
+| `callbacks/*.py` | Medium | Component references |
+
+### Scan Process
+
+1. **Find relevant files**
+   ```
+   glob: **/*.py
+   filter: Contains 'dmc.' or 'dash_mantine_components'
+   ```
+
+2. **Extract component usages**
+   - Parse Python AST
+   - Find all `dmc.*` calls
+   - Extract component name and kwargs
+
+3. **Validate each component**
+   - Call `validate_component(name, props)`
+   - Record violations with file:line reference
+
+4. **Scan for patterns**
+   - Hardcoded colors (regex)
+   - Inline styles (AST)
+   - Fixed dimensions (regex)
+
+5. **Run accessibility checks**
+   - Extract color combinations
+   - Call `accessibility_validate_colors`

+
+---
+
+## Integration with MCP Tools
+
+### Required Tools
+
+| Tool | Purpose | When Used |
+|------|---------|-----------|
+| `validate_component` | Check component props | Every component found |
+| `get_component_props` | Get expected props | When suggesting fixes |
+| `list_components` | Verify component exists | Unknown component names |
+| `theme_validate` | Validate theme config | Theme files |
+| `accessibility_validate_colors` | Check contrast | Color combinations |
+| `accessibility_validate_theme` | Full a11y audit | Theme files |
+
+### Tool Call Pattern
+
+```
+For each Python file:
+  For each dmc.Component(...) found:
+    result = validate_component(
+      component_name="Component",
+      props={extracted_props}
+    )
+    if result.errors:
+      record FAIL violation
+    if result.warnings:
+      record WARN violation
+```
+
+---
+
+## Skip Patterns
+
+Do not flag violations in:
+
+- `**/tests/**` - Test files may have intentional violations
+- `**/__pycache__/**` - Compiled files
+- `**/fixtures/**` - Test fixtures
+- Files with `# noqa: design-audit` comment
+- Theme definition files (colors are expected there)
