magpie-issue-reproducer
Most recent maintenance signal among this shortlist.
| Signal | magpie-issue-reproducer For a single `<issue-tracker>` issue identifying a code-level bug, extract the reporter's example code from the issue body, adapt it to run on the current `<default-branch>`, execute via `<runtime>`, and compose a `verdict.json` describing the observed behaviour vs the expected failure. Read-only on the tracker — produces evidence, never posts. Invoked by `issue-triage` and `issue-reassess`; can also be run standalone. | Implement Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch. |
