What problem does it solve? Autonomous bug-fix pipelines often fail because fixes drift from the diagnosed root cause, skip regression tests, or collide with parallel automation working the same issue. This Skill executes the implementation step of an autofix chain with strict scope control, mandatory test coverage, and tracker-based issue locking. ## Core Features & Use Cases - Brief-driven minimal fixes: Applies only the change identified by the upstream root-cause analysis step, refusing to invent its own diagnosis or broaden scope. - Issue claiming and lock management: Assigns the issue, applies the in-progress label, and posts a claim comment so concurrent automation backs off. - Mandatory regression tests and validation gate: Adds tests that fail without the fix, then runs every command in the committed validation configuration until green. - Use Case: A tracker issue reports a broken permission check. The chain's analyzer pinpoints the faulty file; this Skill claims the issue, edits only that file, adds a failing-then-passing test, runs the full lint/typecheck/test gate, and hands a structured status report to the PR-opening step. ## Quick Start Run the om-fix skill on issue 142 to implement the fix from the root-cause brief, add regression tests, and pass the validation gate.
