Preflight — local CI checks

Before running the checks below, also apply the User-Facing Documentation rule in the root CLAUDE.md: if this change adds/removes/changes a keyboard shortcut, adds a feature or workflow, or changes documented behavior, update the relevant page(s) under apps/docs/content/docs/ (and keyboard-shortcuts-modal.tsx for shortcuts) in the same commit/PR — don't treat CI-green as "done" if docs are stale.

Run the same checks as .github/workflows/ci.yml (Lint & Type Check job), in the same order, from the repo root. All four must pass before committing or opening a PR — CI runs every one of them and fails the build on the first offender.

pnpm lint        # oxlint (type-aware)
pnpm format      # oxfmt --check
pnpm typecheck   # tsc across all packages (turbo)
pnpm knip        # unused files/exports/dependencies

Fixing failures

lint — pnpm lint:fix auto-fixes what it can; fix the rest by hand. If the repo-wide run dies with "Linter process terminated abnormally (possibly out of memory)", fall back to linting the files you changed directly: npx oxlint <changed files...>

format — pnpm format:fix (runs oxfmt --write). Known trap: apps/docs/source.generated.ts is rewritten by fumadocs-mdx (runs during the docs typecheck) with unformatted output. If it shows up, run npx oxfmt --write apps/docs/source.generated.ts and commit the result. Because typecheck regenerates it, run typecheck BEFORE the final format check when touching docs.

typecheck — fix reported type errors. Note pnpm typecheck builds render-engine first via turbo; a stale build can mask/cause errors — rerun after fixing.

knip — reports unused exports, files, and dependencies:

• "Unused exports": if the symbol is only used within its own module, remove the export keyword (don't delete the declaration). If it's truly dead, delete it.
• "Unused files/dependencies": confirm nothing imports them (grep), then remove.
• Only add knip ignore entries for intentional public API, never to silence a real finding.

Order of operations

1. Make your changes.
2. Update apps/docs/content/docs/ (and the shortcuts modal, if applicable) per the User-Facing Documentation rule above.
3. pnpm typecheck (regenerates docs source if applicable).
4. pnpm lint and pnpm format — apply fixes.
5. pnpm knip.
6. Re-run anything whose inputs changed while fixing (e.g. removing an export can affect typecheck).
7. Also run the tests when the change touches render-engine or store logic: pnpm --filter @tooscut/render-engine test.

Only commit/push once all checks exit 0.
