fix(ci): Add concurrency to prevent Claude CLI install conflicts by yamadashy · Pull Request #1014 · yamadashy/repomix

yamadashy · 2025-12-18T13:42:01Z

When multiple Claude issue workflows (claude-issue-similar.yml and claude-issue-triage.yml) run simultaneously for the same issue, they conflict during Claude CLI installation with the error:

Could not install - another process is currently installing Claude.

This PR adds concurrency settings to both workflows with the same group key (claude-issue-${{ github.event.issue.number }}), ensuring sequential execution and preventing installation conflicts.

Walkthrough

Two GitHub Actions workflows receive concurrency configuration updates. Both claude-issue-similar and claude-issue-triage jobs now include concurrency groups keyed by issue number with in-progress run cancellation disabled.

Changes

Cohort / File(s)	Summary
Workflow concurrency configuration `.github/workflows/claude-issue-similar.yml`, `.github/workflows/claude-issue-triage.yml`	Added concurrency group per issue number with `cancel-in-progress: false` to prevent termination of ongoing workflow runs when new issue events trigger execution.

.github/workflows/claude-issue-similar.yml (1)

11-13: LGTM! Concurrency configuration correctly prevents CLI installation conflicts.

The concurrency group keyed by issue number with cancel-in-progress: false ensures that when both workflows trigger for the same issue, they execute sequentially rather than simultaneously. This effectively prevents the "another process is currently installing Claude" error mentioned in the PR description.

The shared group key claude-issue-${{ github.event.issue.number }} across both Claude issue workflows (similar and triage) is intentional and correct—it guarantees that all Claude CLI operations for a given issue happen one at a time.

.github/workflows/claude-issue-triage.yml (1)

11-13: LGTM! Consistent concurrency configuration across Claude workflows.

The implementation matches claude-issue-similar.yml and uses the same concurrency group, which ensures proper serialization of all Claude CLI operations for a given issue across both workflows. This prevents race conditions during CLI installation.

PR Review: fix(ci): Add concurrency to prevent Claude CLI install conflicts

Summary

This is a clean, well-targeted fix for a real race condition issue. The change adds job-level concurrency settings to both Claude issue workflows to prevent simultaneous Claude CLI installations.

Verdict: ✅ LGTM

Detailed Analysis

What the PR does:

Adds concurrency groups with key claude-issue-${{ github.event.issue.number }} to both claude-issue-similar.yml and claude-issue-triage.yml
Uses cancel-in-progress: false to ensure all workflows complete sequentially rather than canceling in-flight jobs

Code Quality:

✅ Minimal, focused change (6 lines added, 0 deleted)
✅ Identical configuration applied consistently to both workflows
✅ Follows GitHub Actions best practices for concurrency control
✅ Commit message follows Conventional Commits format per CLAUDE.md guidelines

Design Considerations:

✅ Using cancel-in-progress: false is the correct choice here - both triage and similar-issue detection should complete for each issue
✅ The shared group key ensures the two workflows serialize against each other, not just within themselves
✅ Job-level placement (vs workflow-level) is appropriate since these are single-job workflows

Premortem Analysis - Potential Failure Scenarios

Scenario	Risk	Mitigation
Long queue buildup if many issues created rapidly	Low	5-minute timeout already exists on both jobs
Job waiting too long for concurrency slot	Low	GitHub Actions eventually releases stale locks; timeouts provide backstop
Future workflow additions forgetting concurrency	Low	Document this pattern if more Claude workflows are added

No significant risks identified. The existing timeout-minutes: 5 setting provides adequate protection against queue buildup scenarios.
