Safe to merge: the change adds one README Tools bullet in the correct format and alphabetical order, with clean CI and no code or config impact.

Review details and evidence

Material unknowns

• Whether the external URL https://github.com/stefbuilds/cross-examine resolves and whether the one-line description accurately matches the linked project. If the URL 404s or the description is materially inaccurate, the README quality bar is not met and the merge posture would flip to blocking.
  • Check: Optionally verify the external link resolves and the description matches before or after merge.

• Reviewed changed regions in README.md.
