Protect Main Branch
Protect Main Branch: what it does, its label on each agent, what it misses, and examples.
Catalog policy protect-main-branch, version 0.0.4, labelled advisory on Claude Code.
What it does
Keeps agents off main and master: a git hook reads the current branch at commit time and parses the refs being pushed at push time. The hook refuses a violation only where it is installed. As skill text alone this is advice, and nothing stops one.
