Show HN: A local merge queue for parallel Claude Code agents

A developer has created a local merge queue tool for parallel Claude Code agents that serializes concurrent changes to prevent conflicts, redundant builds, and test failures. The open-source tool runs on your machine at zero cost, offering similar functionality to GitHub's Merge Queue but without cloud infrastructure or billing. It can be installed via npm and configured with a single file to manage multiple agents working on the same codebase simultaneously.
