**Before writing a single line of code:** run `mcp__codescene__code_health_score` to check the current codebase health against `.codescene-thresholds`. If the score is already below the threshold, **stop and refactor first** — find the worst files with the MCP, improve them, commit, then start the task. Never start feature work on a codebase that is already below the gate.
Write smoke test in `tests/smoke/<slug>.spec.ts` only if feature touches: vault open, note create/save/delete, search, wikilink navigation, git commit/push, conflict resolution. Do NOT write Playwright tests for cosmetic changes — use Vitest instead. Suite must stay under **10 minutes**.
Use `osascript` for keyboard interactions. Write result as Todoist comment (✅ or ❌). **⚠️ WKWebView:** `osascript keystroke` blocked inside editor — rely on Playwright for text input features.
- **A task is NOT done until `git push origin main` succeeds.** If the hook blocks: read the error, fix it (clippy, tests, CodeScene, build), commit the fix, push again. **⛔ NEVER use --no-verify**
**Test quality (Kent Beck's Desiderata):** Isolated · Deterministic · Fast · Behavioral · Structure-insensitive · Specific · Predictive. Fix flaky tests first. Prefer E2E over unit tests for user flows.
Pre-commit and pre-push hooks enforce **Hotspot Code Health** and **Average Code Health** ≥ thresholds in `.codescene-thresholds`. Both gates block commit/push. Thresholds are a **ratchet** — only go up, auto-updated after each successful push. Never add `// eslint-disable`, `#[allow(...)]`, or `as any`.
**Before every commit:** run `mcp__codescene__code_health_review` on files you touched and verify score is higher. **Boy Scout Rule:** every file you touch must leave with a higher score.
**If CodeScene gate blocks your push:** use `mcp__codescene__code_health_score` to find the worst file, refactor it, commit, push again. Do NOT stop or wait for laputa-refactor — that is a background loop, not a substitute for fixing your own regressions.
ADRs live in `docs/adr/`. Create in the same commit as the code. Never edit existing — create a new one that supersedes. Use `/create-adr`. **When:** new dependency, storage strategy, platform target, core abstraction, cross-cutting pattern. **Not for:** bug fixes, styling, refactors.
After any Tauri command, new component/hook, data model change, or new integration: update `docs/ARCHITECTURE.md`, `docs/ABSTRACTIONS.md`, and/or `docs/GETTING-STARTED.md` in the same commit.
Default to `demo-vault-v2/`. If you must use `~/Laputa/` for testing: **never commit changes** — always run `cd ~/Laputa && git checkout -- . && git clean -fd` when done.
**Always use shadcn/ui components.** Never use raw HTML form elements (`<input>`, `<select>`, `<button>`, native `<input type="date">`, etc.) for user-facing UI. Every interactive element must use the shadcn/ui equivalent:
| Need | Use |
|---|---|
| Text input | `Input` from shadcn/ui |
| Dropdown/select | `Select` from shadcn/ui |
| Date picker | `Calendar` + `Popover` from shadcn/ui (NOT native `<input type="date">`) |
| Button | `Button` from shadcn/ui |
| Autocomplete/combobox | Reuse existing combobox components from the app (check `src/components/`) |
| Wikilink picker | Reuse the wikilink autocomplete component already used in the editor and Properties panel |
| Emoji picker | Reuse the emoji picker component already used for note/type icons |
| Color picker | Reuse the color swatch picker used for type customization |
| Toggle/switch | `Switch` or `ToggleGroup` from shadcn/ui |
**When in doubt:** search `src/components/` for an existing component before building new. **Visual language:** all new UI must feel native to Laputa — if it looks like a browser default, it's wrong.
