 - After code changes (not docs): `npm run check` (full output, no tail). Fix all errors, warnings, and infos before committing. Does not run tests.
 - Never run `npm run build` or `npm test` unless requested by the user.
-- Never run the full vitest suite directly: it includes e2e tests that activate when endpoint/auth env vars are present. For all non-e2e tests, run `./test.sh` from the repo root.

+- Never run the full vitest suite directly: it includes e2e tests that activate when endpoint/auth env vars are present. For all non-e2e tests, run `./test.sh` from the repo root. Otherwise run specific tests from the package root:
+  - Vitest: `node "$(git rev-parse --show-toplevel)/node_modules/vitest/dist/cli.js" --run test/specific.test.ts`
+  - `packages/tui` (`node:test`): `node --test test/specific.test.ts`
 - If you create or modify a test file, run it and iterate on test or implementation until it passes.
 - For `packages/coding-agent/test/suite/`, use `test/suite/harness.ts` + the faux provider. No real provider APIs, keys, or paid tokens.
 - Put issue-specific regressions under `packages/coding-agent/test/suite/regressions/` named `<issue-number>-<short-slug>.test.ts`.
