About env-guard

env-guard adds a PreToolUse hook that checks every Read, Bash and Grep request before it runs. If it mentions a .env file, the action is blocked, and Claude is told why. .env.example, .env.sample and .env.template still work.

It also adds /env-guard:env-check, which lists any .env files tracked by git and shows how to untrack them.

What it never does:
• No network access; nothing is sent anywhere
• Never reads, logs or stores your .env contents
• Never changes settings.json or your permissions

Install in Claude Code:
/plugin install env-guard --marketplace yannigoyal/env-guard

Free and open source (MIT). Needs jq.

What is env-guard?

env-guard is a published development & workflow plugin for AI coding agents in the Claude Code ecosystem, developed by yannigoyal and distributed through the HOL AI plugin registry. Claude Code plugin that checks Read, Bash and Grep requests for `.env` paths and reports tracked `.env` files without reading their values.

Continuous scanner CI not detected

This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.

Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.

README badge detected

The source repository README links to this HOL listing. Distribution, not security evidence. It adds a 2% engagement adjustment to the overall trust score and never changes the security result.
