About this capability

Diagnose and fix a Fallow false positive or false negative through extraction, resolution, graph, analysis, reporting, and real-consumer verification.

What this skill tells your AI

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

  1. Reproduce on current main with --format json --quiet.
  2. Reduce to a minimal fixture without losing the behavior.
  3. Trace the finding through extract, resolve, graph, reachability, analysis, suppression, filters, and report assembly.
  4. Fix the earliest incorrect layer.
  5. Add a regression test that fails without the fix.
  6. Run the fixed binary on a real consumer project with a cleared .fallow/ cache and compare old versus new output.
  7. Run review with the affected surface reviewers.

Do not tune expected output around one fixture when the semantic model requires a broader correction.
