SIG audit loop

SkillDev tools

Lets your agent iteratively improve code maintainability, keeping only changes that measurably improve it without regressions.

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 SIG audit loop skill

About this capability

Iteratively improve Fallow maintainability using measured SIG audit deltas, retaining only changes that improve the targeted property without regressions.

What this skill tells your AI

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

  1. Run sig-audit and select one weak property.
  2. Identify a bounded structural change with a measurable expected effect.
  3. Measure before, implement, and measure after with identical settings.
  4. Keep the change only when the target improves and verification remains green.
  5. Repeat until the target is met or further changes have no credible benefit.
  6. Run review before proposing the final result.

Never combine unrelated cleanup into one measurement iteration.
