Docs Tracker - Automatic Documentation System
Purpose
This skill automates documentation maintenance:
- Detects modified files via git diff
- Compares with existing documentation
- Creates docs for new files
- Updates docs for modified files
- Removes docs for deleted files
- Generates automatic changelog
Execution Flow
1. DETECT CHANGES → git diff --name-status
↓
2. CLASSIFY CHANGES → A=Added, M=Modified, D=Deleted
↓
3. CHECK EXISTING DOCS → docs/, codebase-knowledge/domains/
↓
4. EXECUTE ACTIONS → Create, update, or remove docs
Detection Commands
Changes Since Last Commit
git diff --name-status HEAD~1
Changes vs Main
git diff --name-status main..HEAD
Added Files
git diff --name-status main..HEAD | grep "^A"
Modified Files
git diff --name-status main..HEAD | grep "^M"
Deleted Files
git diff --name-status main..HEAD | grep "^D"
Detailed File Diff
git diff main..HEAD -- path/to/file.ts
File → Doc Mapping
| File Type | Related Documentation |
|---|---|
server/routers/*.ts |
codebase-knowledge/domains/[domain].md |
server/models/*.ts |
codebase-knowledge/domains/[domain].md |
app/**/page.tsx |
docs/flows/[feature].md |
components/**/*.tsx |
docs/components/[component].md (if complex) |
lib/**/*.ts |
docs/utils/[lib].md (if exported) |
Update Rules
CREATE Doc When:
- New file in
server/routers/→ Update domain - New file in
server/models/→ Update domain - New page in
app/→ Create flow doc if complex - New complex component → Consider doc
UPDATE Doc When:
- tRPC procedure changed signature
- Model changed schema
- Page changed main flow
- Connections between domains changed
REMOVE Doc When:
- File was deleted
- Feature was completely removed
- Component was discontinued
