You'll notice
Gerrit remotes are now detected via Change-Id lookup, so PR-lifecycle announcements work there as they do for GitHub and GitLab.
Claude Code can now detect a Gerrit code-review remote by matching a googlesource.com URL pattern, extract the Change-Id from the last commit, and query the Gerrit REST API for the matching open change. When found, this powers the same 'started' PR-lifecycle announcement already used for GitHub and GitLab.
