# Bug Forensics Use this skill only when the task explicitly asks to find or repair a bug, regression, flaky failure, incident, or security bug. The profile is optional and disabled by default for ordinary feature work. Adapter task intake may recommend this profile through `bugForensicsAdvisory`. Treat that as an advisory marker only. Do not claim the workflow gate is active unless the reviewed task or frozen plan explicitly opts in. ## Contract Before accepting a patch, collect schema-backed evidence for: - symptom; - reproduction before modification; - stable failure fingerprint; - hypothesis ledger with accepted and rejected hypotheses; - root cause; - minimal patch; - regression proof for the same fingerprint; - no collateral damage through the canonical fix-impact receipt. ## Inputs Required phase-1 receipts: - `agent-bug-reproduction-receipt.v1`; - `agent-failure-fingerprint.v1`; - `agent-bug-hypothesis-ledger.v1`; - `agent-regression-proof-receipt.v1`; - `agent-fix-impact-receipt.v1`. Reuse `agent-fix-impact-receipt.v1` for behavior impact. Do not create a bug-specific competing fix-impact schema. ## Gates - Reproduction must be red before any code modification. - Regression proof must show the same fingerprint red before and green after. - Minimal patch gate must justify any file outside the suspect scope. - Cross-check is advisory unless the frozen plan explicitly opts into blocking use. When used, reuse `agent-cross-check-receipt.v1` with token/resourc
