Skill: verify-before-commit

When to use

After completing any implementation task, before git commit.

Steps

Pre-commit:

1. RUN: <type-check-cmd> — detect from repo: npx tsc --noEmit (package.json) / go build ./... (go.mod). Fix all errors.
2. RUN: <lint-cmd> — detect: npx eslint src/ / go vet ./.... Fix errors; note warnings.
3. RUN: <test-cmd> — detect: npm test / go test ./.... Fix failures.
4. Smoke check: manually verify the golden path works end-to-end.
5. Commit with message describing why, not what.
