Constraints

  • Do NOT upgrade to pre-release, beta, or canary versions. Use only stable releases.
  • Do NOT delete lockfiles (package-lock.json, yarn.lock, pnpm-lock.yaml).
  • Do NOT run npm audit fix --force. Use npm audit fix only.
  • Do NOT proceed to the next phase until the current phase passes its gate check.
  • Execute phases sequentially. No phases run in parallel.
  • If /speckit.analyze is unavailable, manually compare spec acceptance criteria against test results as a fallback.
