 - **CLI (cli.py)**: Uses Typer with Rich for terminal UI. Entry point is `app()`.
 - **Installer**: Copies command/workflow templates to target project's `.claude/` directory (or `.cursor/` for Cursor).
 - **Chunker**: Creates `.chunks.json` files alongside markdown, tracks changes via `docs/.chunks/manifest.json`.
+- **Coverage**: Analyzes codebase for routes/components/models, matches against docs, reports coverage with visual progress bars.
 - **Embeddings**: Calls OpenAI API (text-embedding-3-small, 1536 dimensions), outputs `docs/.chunks/sync.sql` for pgvector import.
 - **Server**: Auto-discovers nav structure from folder hierarchy, generates ephemeral `mkdocs.yml`.

 # Edit docs in your editor - changes auto-sync!
 ```
 
+### `aidocs coverage`
+
+Analyze documentation coverage for your codebase. Scans for routes, components, and models, then checks which items are mentioned in your documentation.
+
+```bash
+aidocs coverage                     # Show coverage summary
+aidocs coverage --format json       # Machine-readable output
+aidocs coverage --format csv        # CSV export
+aidocs coverage --ci                # Exit code 1 if below 80%
+aidocs coverage --threshold 70      # Custom threshold
+aidocs coverage -c ./src            # Specify codebase path
+aidocs coverage --all               # Show all items
+```
+
+**Options:**
+| Option | Description |
+|--------|-------------|
+| `--codebase, -c` | Path to codebase root (default: parent of docs dir) |
+| `--format, -f` | Output format: `summary`, `json`, or `csv` |
+| `--threshold, -t` | Minimum coverage percentage (exit 1 if below) |
+| `--ci` | CI mode: exit 1 if coverage below 80% |
+| `--save/--no-save` | Save report to `.chunks/coverage.json` (default: save) |
+| `--all, -a` | Show all items (documented and undocumented) |
+
