Suggestions for Improvement + +### 10.1 Add --db flag to embed and search +The `embed` and `search` commands lack a `--db ` option, unlike most other query commands.

Consider adding advisory file locking or a warning when another process holds the DB. + +### 10.3 Update notification for dev versions +The update notification feature (`update-check.js`) should suppress notifications for dev/prerelease versions to avoid false positives. + +### 10.4 Consistent file counts across builds +File counts fluctuated slightly (99-106) across builds due to concurrent repo modifications. While not a bug, logging which files were added/removed between builds would help diagnose discrepancies. + +--- + +## 11.
