31 Claude Code mods on GitHub, and how far each one reaches into your machine

Read straight off Claude Code's own plugin validator, which lists a mod's hooks and $ calls before any of its code runs. Scanned against Claude Code 2.1.272 on 2026-09-15, rescanned nightly. Source, method and the curated list: awesome-claude-code-mods.

Reach is the widest thing a mod's $ calls can touch. It is a footprint, not a verdict. A PR tracker has to run gh, and a breathing band only draws. Sees lists what a mod observes without a matcher, such as every prompt or every tool call.
