## System Components

### Scripts Location

All scripts in: `~/.claude/commands/workflow/lib/`

**Master orchestrator:**
- `run-all-updaters.sh` - Coordinates all three updaters

**Individual updaters:**
- `update-changelog.sh` - CHANGELOG.md auto-generation
- `update-mkdocs-nav.sh` - mkdocs.yml navigation sync
- `update-claude-md.sh` - .STATUS/CLAUDE.md updates

**Phase 1 detectors (dependencies):**
- `detect-changelog.sh` - Find missing commits
- `detect-orphaned.sh` - Find orphaned docs
- `detect-divergence.sh` - Find navigation issues
- `detect-claude-md.sh` - Check .STATUS freshness
- `run-all-detectors.sh` - Run all detectors

### Integration Points

**With /workflow:done:**
- Step 1.6: Auto-update documentation
- Runs automatically during session completion

**With git:**
- Parses commit messages
- Generates GitHub links
- Tracks last update markers

**With mkdocs:**
- Updates navigation structure
- Validates YAML syntax
- Tests builds with `--strict` flag

## Common Workflows

### Daily Development Session

```bash
# Morning: Start work
cd ~/projects/your-project
git checkout -b feature/new-thing

# ... code for 2 hours ...

# Commit with conventional format
git commit -m "feat: implement new feature"
git commit -m "fix: resolve bug"
git commit -m "docs: add guide"

# End of session
/workflow:done
  → Auto-updates run automatically
  → Press Enter to confirm
  → Done in 30 seconds!
```

### Before Major Release

```bash
# Generate automatic entries
~/.claude/commands/workflow/lib/run-all-updaters.sh --dry-run

# Review output, adjust commit messages if needed

# Apply updates
~/.claude/commands/workflow/lib/run-all-updaters.sh --apply

# Manually edit CHANGELOG for release notes
vim CHANGELOG.md
  → Add migration guides
  → Add breaking change details
  → Polish for public release

# Commit
git commit -m "docs: prepare v1.0.0 release"
```

### CI/CD Integration (Future)

```bash
# In GitHub Actions or similar
- name: Update Documentation
  run: |
    ~/.claude/commands/workflow/lib/run-all-updaters.sh --auto
    git add CHANGELOG.md mkdocs.yml
    git commit -m "docs: auto-update [skip ci]"
    git push
```
