Investigates a root cause and files a minimal fix PR for a reported bug or observability finding.

Create a fix PR Overview You are investigating a problem and filing a pull request that resolves it. This builds on the investigate skill — do the investigation properly first, don't jump to a fix without evidence. Use the gh CLI for all GitHub operations (auth comes from your gh login) and standard Bash / Edit / Read / Grep for everything else. Workflow 1. Investigate. Use the investigate skill to find the root cause. Cite the exact trace ID, log line, error group, and code location that pins the problem. 2. Confirm there isn't already a PR open. Before filing anything, search GitHub for an existing open PR addressing the same issue — gh pr list search "<keywords " state open . If one exists, direct the user to it — do not create a duplicate. 3. Judge whether a PR is the right tool. If the fix requires a config change, a flag flip, or a change outside the code you can access, describe the solution instead of filing a PR. 4. Get the repo. Clone it if you don't already have it locally — gh repo clone <owner /<repo . 5. Check for repo conventions. Read agents.md or CLAUDE.md at the repo root — these describe repo specific rules your fix needs to respect. 6. Make the change. Minimal diff. Don't refactor surrounding code, don't add features, don't fix unrelated bugs you happen to notice. One PR, one fix. 7. Set git identity before committing — see pr conventions.md . 8. Commit, push, and file the PR. See pr conventions.md for branch naming and PR body rules. What's a good fix Changes the smallest possible number of lines Preserves current production behavior unless the bug IS the current behavior Doesn't depend on assumptions you can't verify from the evidence Would pass a code review skill's check if one existed What isn't Sweeping refactors unrelated to the reported problem Speculative null checks or error handling added "while you're in there" Changes to tests that hide the underlying bug Bumping dependency versions to fix a symptom Restricted tools If gh isn't installed or gh auth status shows no auth, surface the error to the user and stop — don't try alternative auth schemes. Never include in a PR GitHub access tokens or any other secrets or credentials. Debugging logs or print statements you added during investigation. Follow the repo's own commit and PR conventions for everything else.
