What problem does it solve? Turning a GitHub issue into a merged pull request often fails through skipped steps: unread issue threads, duplicate PRs, fixes that fight intentional design, regression tests that prove nothing, and dishonest CI claims. This Skill enforces the full discipline from issue to verified PR. ## Core Features & Use Cases - Premise Validation: Reads the full issue thread, sweeps for duplicate PRs and prior commits, and checks git history to confirm the reported bug is not deliberate design. - Class-Level Fixes with Proven Tests: Implements the smallest complete change, fixes the same bug shape at sibling call sites, and sabotage-tests the regression test to confirm it fails without the fix. - Honest CI Shepherding: Opens the PR immediately to start CI, distinguishes real failures from baseline or infra flakes, and closes the loop by commenting the PR link on the issue. - Use Case: A maintainer says "Fix issue #123 and open a PR" — the Skill reads the thread, rules out duplicates, reproduces the bug, ships a tested fix, and reports live CI state. ## Quick Start Fix GitHub issue number 123 in this repository and open a pull request with a verified regression test and honest CI status.
