What problem does it solve? Regression issues for Phase 1 picker/extractor components often arrive without verbatim input snippets, expected outputs, or reproducible fixtures, causing repeated guessing rounds and thrashing across multiple plugin releases. This Skill gates every fix behind a mandatory intake check so incomplete issues are bounced back before any code is touched. ## Core Features & Use Cases - Hard intake gate: Runs regression_issue_intake_check.py before any code is read, refusing to start fixes on issues missing verbatim input, expected output, or a drop-in fixture. - Fixture-first fixing: Requires the new fixture to fail on current code before writing the fix, then runs the full fixture suite with a pre-commit thrash guard against silent fixture flips. - Self-verify and close lifecycle: Guides the agent to reproduce the original failure, run the full CI suite, push a chip-agnostic fix, and close the issue with the core-closed label and a structured 5-section comment. - Use Case: When asked to "fix issue #42" affecting the L6.fsm_states extractor, the Skill first validates the issue's completeness, lands the fixture, confirms it fails, then drives the fix through verification and closure. ## Quick Start Ask the agent to read and fix GitHub issue number N for a Phase 1 picker or extractor regression, and it will run the intake check before doing anything else.
