Recent Code Bugfix
Overview
Find a bug introduced by the current author in the last week, implement a fix, and verify it when possible. Operate in the current working directory, assume the code is local, and ensure the root cause is tied directly to the author’s own edits.
Workflow
1) Establish the recent-change scope
Use Git to identify the author and changed files from the last week.
- Determine the author from
git config user.name/user.email. If unavailable, use the current user’s name from the environment or ask once. - Use
git log --since=1.week --author=<author>to list recent commits and files. Focus on files touched by those commits. - If the user’s prompt is empty, proceed directly with this default scope.
2) Find a concrete failure tied to recent changes
Prioritize defects that are directly attributable to the author’s edits.
- Look for recent failures (tests, lint, runtime errors) if logs or CI outputs are available locally.
- If no failures are provided, run the smallest relevant verification (single test, file-level lint, or targeted repro) that touches the edited files.
- Confirm the root cause is directly connected to the author’s changes, not unrelated legacy issues. If only unrelated failures are found, stop and report that no qualifying bug was detected.
3) Implement the fix
Make a minimal fix that aligns with project conventions.
- Update only the files needed to resolve the issue.
- Avoid adding extra defensive checks or unrelated refactors.
- Keep changes consistent with local style and tests.
4) Verify
Attempt verification when possible.
- Prefer the smallest validation step (targeted test, focused lint, or direct repro command).
- If verification cannot be run, state what would be run and why it wasn’t executed.
5) Report
Summarize the root cause, the fix, and the verification performed. Make it explicit how the root cause ties to the author’s recent changes.
