Free tool - Claude Code plugin
Your agent does exactly what you want. Nothing more.
Skill Gate is a free Claude Code plugin that mutes skills firing for no reason. You choose which skills the agent may run and which you block, hard at the hook level.

Problem
The agent does too much, not too little
- Claude fires a skill you did not know existed.
- Brainstorming or TDD kicks in when you only wanted a quick fix.
- You burn tokens and focus on a process you never asked for.
How it works
Three steps to quiet
- You invoke the focus-guard skill in Claude Code.
- It lists every available skill by the discovery hierarchy user, project, project.local and lets you add or remove them from the blocklist.
- It generates a PreToolUse hook on Skill that stops blocked skills before they fire. Deterministically, locally.
What you get
Control without editing config
- A blocklist managed by command, not by hand-editing JSON.
- Full skill discovery across the user, project, project.local hierarchy.
- The hook generated for you. No hook code to write.
- Runs offline and sends nothing. Your gate, your machine.
