CI Fix

Diagnose CI failures and implement fixes with minimal, targeted diffs. Pushes fixes to a dedicated branch without creating PRs.

Prerequisites

Verify GitHub CLI authentication before proceeding:

gh auth status

If not authenticated, instruct the user to run gh auth login first.

Workflow

1. Locate the Failing Run

Determine the failing workflow run. If working on a PR branch:

gh pr view --json statusCheckRollup --jq '.statusCheckRollup[] | select(.conclusion == "FAILURE")'

If working from a branch or run ID:

gh run list --branch <branch> --status failure --limit 5
gh run view <run-id> --verbose

2. Extract Failure Logs

Pull logs from failed steps to identify the root cause:

gh run view <run-id> --log-failed

For deeper inspection:

gh run view <run-id> --log --job <job-id>
gh run download <run-id> -D .artifacts/<run-id>

3. Identify Root Cause

Analyze logs for common failure patterns:

• Build/compilation errors: Missing dependencies, type errors, syntax issues
• Test failures: Assertion failures, timeouts, flaky tests
• Linting/formatting: Style violations, unused imports
• Environment issues: Missing secrets, permissions, resource limits

Prefer the smallest fix that resolves the issue. Deterministic code fixes are better than workflow plumbing changes.

4. Implement the Fix

Make minimal, scoped changes matching the repository's existing style:

• Fix only what's broken—avoid unrelated refactoring
• Keep changes to the failing job/step when possible
• If modifying workflow files, preserve existing permissions and avoid expanding token access

5. Push to Fix Branch

Create or update a dedicated fix branch:

git checkout -b ci-fix/<original-branch>
git add -A
git commit -m "fix: resolve CI failure in <job-name>

Co-Authored-By: Warp <agent@warp.dev>"
git push -u origin ci-fix/<original-branch>

If the fix branch already exists, update it:

git checkout ci-fix/<original-branch>
git pull origin <original-branch>
# make fixes
git commit -m "fix: <description>

Co-Authored-By: Warp <agent@warp.dev>"
git push

6. Verify the Fix

Trigger CI on the fix branch and monitor:

gh run list --branch ci-fix/<original-branch> --limit 1
gh run watch <new-run-id> --exit-status

To rerun only failed jobs:

gh run rerun <run-id> --failed

Safety Notes

• Avoid pull_request_target unless explicitly requested—it can expose secrets to untrusted code
• Keep workflow permissions: minimal; don't broaden access to make tests pass
• For flaky tests, prefer deterministic fixes over blind reruns

Deliverable

After fixing, provide a brief summary:

• Failing run: Link or ID
• Root cause: What broke and why
• Fix: What changed
• Verification: New run link showing green status
