protect-main-branch

protect-main-branch is a plugin for Claude Code from lacolaco/claude-plugins. Its token cost is not measured, scanned A, original, MIT.

A Claude Code plugin that protects selected Git branches, usually the main branch, from changes. Git is the version-control tool used to track code and branches are separate lines of work.

In plain words
What is it for?
Use it to block commits, pushes, merges, rebases, resets, cherry-picks, reverts, and similar operations on protected branches.
Why use it?
It prevents accidental commits or other history-changing Git operations on branches that should stay stable. The protected branch list and allowed operations can be configured.

Security

Grade A, and why

protect-main-branch scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 1 hook travel with it, and installing the plugin installs all of them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
