 - **lint**: all `${err}` in template literals → `${String(err)}`; `String(args['key'] ?? '')` → `strArg(args, 'key')` helper; unused `onProgress` param → `_onProgress`; WebSocket `onerror` `err` type is `Event` → use `err.type`
 
 ## Work Queue (next steps)
-1. [ ] Runtime smoke test: `bun run start --help`
-2. [ ] Test with a real Mattermost config (optional — user can do this)
-3. [ ] Write sample `~/.nanobot/config.json` in README or docs
+1. [x] Create workspace helper module (src/workspace.ts) with ensureWorkspace() and syncTemplates()
+2. [x] Create onboard command (src/cli/onboard.ts) with path argument and directory-not-empty guard
+3. [x] Update src/cli/commands.ts to use ensureWorkspace() instead of inline mkdirSync
+4. [x] Typecheck and lint pass (0 errors)
+5. [x] Runtime smoke test: `bun run nanobot --help`
+6. [x] Test onboard command: `bun run nanobot onboard [path]`
+7. [ ] Test with a real Mattermost config (optional — user can do this)
 
 ## Key Decisions Made
 - Mattermost channel uses raw WebSocket + fetch (no mattermostdriver, no SSL hack)

 ## Known Issues / Risks
 - `ollama-ai-provider` v1.2.0 returns `LanguageModelV1` (not V2/V3 as expected by AI SDK v6) — cast used at call site. Works at runtime.
