lmiranda 2d51df7a42 feat(marketplace): command consolidation + 8 new plugins (v8.1.0 → v9.0.0) [BREAKING]
Phase 1b: Rename all ~94 commands across 12 plugins to /<noun> <action>
sub-command pattern. Git-flow consolidated from 8→5 commands (commit
variants absorbed into --push/--merge/--sync flags). Dispatch files,
name: frontmatter, and cross-reference updates for all plugins.

Phase 2: Design documents for 8 new plugins in docs/designs/.

Phase 3: Scaffold 8 new plugins — saas-api-platform, saas-db-migrate,
saas-react-platform, saas-test-pilot, data-seed, ops-release-manager,
ops-deploy-pipeline, debug-mcp. Each with plugin.json, commands, agents,
skills, README, and claude-md-integration. Marketplace grows from 12→20.

# Staleness Metrics
## Purpose
Defines how to measure documentation staleness relative to code changes.
## When to Use
- **doc stale-docs**: Commit-based staleness detection
- **doc audit**: Age-based analysis
---
## Staleness Calculation
```
Commits Behind = Code Commits Since Doc Update
Days Behind = Days Since Doc Update - Days Since Code Update
```
---
## 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 |
---
## Relationship Detection
### 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
---
## Git Commands
```bash
# Last doc commit
git log -1 --format="%H %ai" -- docs/api.md
# Last code commit for related files
git log -1 --format="%H %ai" -- src/api/
# Commits to code since doc update
git rev-list <doc-commit>..HEAD -- src/api/ | wc -l
```
---
## Configuration
`.doc-guardian.yml`:
```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/**
```
---
## Output Format
```

| File | Last Updated | Commits Behind | Related Code |
|------|--------------|----------------|--------------|
| README.md | 2024-02-20 | 15 | package.json, src/index.ts |
### Aging (6-10 commits behind)
