What gets installed

File	Purpose
.gemini/settings.json	BeforeTool hook — calls wrapper script
.gemini/hooks/miskin-hook-gemini.sh	Wrapper script that execs miskin hook gemini
GEMINI.md	Caveman prompt

How the hook works

A BeforeTool hook is registered in Gemini's settings.json:

{
  "hooks": {
    "BeforeTool": [{
      "matcher": "run_shell_command",
      "hooks": [{
        "type": "command",
        "command": "/home/user/.gemini/hooks/miskin-hook-gemini.sh"
      }]
    }]
  }
}

The wrapper script simply execs the miskin binary:

#!/bin/bash
exec miskin hook gemini

miskin hook gemini reads stdin JSON, extracts the command, and returns Gemini's protocol:

{
  "decision": "allow",
  "hookSpecificOutput": {
    "tool_input": { "command": "miskin docker ps" }
  }
}

Enable Caveman Mode

miskin config set caveman.enabled true

Writes to GEMINI.md.

Uninstall

miskin init --agent gemini --uninstall
