False Positive Reduction
Use this skill to run a full false-positive reduction cycle on the bundled playbook set. It extracts patterns shared across two or more playbooks, classifies which conflicts are genuine risks, fixes them by adding match.none discriminators, adds adversarial fixture logs and test cases to defend the boundary, and verifies with make review-update and make test. Trigger it when the baseline is green but you want to proactively narrow ambiguous pattern overlaps. Do not use it when a specific fixture is already failing — use playbook-refinement or baseline-regression instead.
