tool-gates

A permission-control add-on for Claude Code that checks shell commands, file access, searches, skills, and MCP tool calls. It parses Bash commands to decide whether configured actions should be allowed.

In plain words
What is it for?
Governing Claude Code shell and file operations, search, Skill use, and MCP calls; deferring harmless requests to Claude Code's permission resolver and enforcing configured denials.
Why use it?
It reduces the risk of an agent running unwanted commands, reading or changing restricted files, or using blocked tools while still allowing approved requests.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Grade A, and why

tool-gates 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 yesterday.

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 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.
