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 CI status reported without evidence. This Skill enforces the end-to-end discipline from issue triage to verified CI. ## Core Features & Use Cases - Premise and duplicate validation: Reads the full issue thread, sweeps for existing PRs and recent fixing commits, and checks git history to confirm the reported bug is not deliberate design. - Class-level fixes with proven regression tests: Fixes the same bug shape at sibling call sites and runs a sabotage check confirming the new test fails on pre-fix code. - Honest CI shepherding: Opens the PR immediately to dispatch CI, distinguishes introduced failures from baseline flakes, and closes the loop by commenting the PR link on the issue. - Use Case: Given "Fix issue #123 and open a PR", the Skill reads the thread, reproduces the bug, writes a failing regression test, implements the minimal fix, and reports live CI state. ## Quick Start Ask the agent to fix GitHub issue number 123 in the current repository and open a pull request with verified CI status.
