What problem does it solve? When a build, compiler, linter, or type-checker fails, developers often guess at fixes, over-edit the diff, or silence errors with unexplained suppressions. This Skill enforces a disciplined repair workflow: read the tool's output literally, make the minimal change at the established location, and prove the fix worked by re-running the failing check. ## Core Features & Use Cases - Literal error-driven repair: Reads the exact error, rule name, and location reported by build, lint, and type-check tools, preferring automated fixes like --fix flags and codemods before manual edits. - Diagnosis handover support: Acts on a confirmed causal chain and failing regression test from a prior diagnosis, verifying the test goes green with the fix and red again when reverted. - Guardrails against scope creep: Forbids refactors, renames, weakened tests, and unexplained suppressions riding along in the repair diff. - Use Case: After CI reports eslint failures on a pull request, invoke the Skill to run the linter, apply autofixes, manually resolve remaining violations at their reported locations, and confirm every project check passes before committing. ## Quick Start Fix the lint errors reported in the latest CI run and verify all project checks pass afterward.
