Running Preflight Checks

Category: Engineering  ·  Sub-category: testing  ·  Last updated:

Runs the brokenrobot.xyz quality gate — type-check, lint, format-check, spec validation, DESIGN lint, design-token drift, build, and the third-party-resource guardrail — and summarizes failures. Use before committing a change or handing it to review; the same set CI's Verify and Build jobs enforce. This is the non-visual half of Verify; pair it with testing-visual-regression.

From the source SKILL.md

Run the gate from the repo root. Run all eight steps even when one fails — stopping at the first failure hides the rest.

npm run type:check       # astro check && tsc --noEmit
npm run lint:check       # astro sync && eslint
npm run format:check     # prettier --check
npm run specs:check      # openspec validate --all --strict
npm run designmd:check   # errors fail; warnings and infos are advisory
npm run tokens:check     # drift fix is `npm run tokens:generate`, which the caller runs
…
