Glab

This one gives Claude what it needs to work with GitLab's CLI without the usual fumbling around. It covers the practical stuff like creating merge requests, posting inline diff comments (which has some gotchas about JSON vs form fields), and monitoring CI/CD pipelines. The authentication setup is straightforward, and there's good coverage of self-hosted GitLab instances. What's useful here is the distinction between discussion notes and diff notes, plus the API command patterns since glab doesn't expose everything through convenience commands. If you're doing GitLab workflows in the terminal or want Claude to help review merge requests with proper threaded comments, this handles the specifics that aren't obvious from glab's help text alone.
