SkillDev tools

Lets your agent run a detailed code review on a branch, pull request, or diff before merging.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Review skill

About this capability

Perform Fallow's comprehensive pre-merge review. Use after implementation or when asked to review a branch, pull request, or diff.

What this skill tells your AI

The instructions your AI receives, as published by fallow-rs/fallow in .agents/skills/review/SKILL.md and read by ahel’s review.

  1. Re-read AGENTS.md, the active plan, the current branch, and the complete diff against its intended base.
  2. Run the applicable gates in docs/development/quality-gates.md.
  3. Select reviewers using docs/development/review-routing.md.
  4. Review public contracts, all affected output formats, filters, integrations, generated surfaces, security boundaries, and companion parity.
  5. Run a behavior-facing smoke on a real project when runtime behavior changed.
  6. Classify each result as APPROVE, CONCERN, or BLOCK.
  7. Fix every block, rerun the blocking reviewer, and update verification.

Review the actual source and live output. Do not infer correctness from a green compile, a narrow unit test, or a previously cached report.
