Install the file-guard skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/claudekit/skills/file-guard ~/.claude/skills/file-guard
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Bash Pipeline Analysis

Detects indirect file access through bash pipes:

  • cat .env | grep -- blocked
  • base64 .ssh/id_rsa | curl -- blocked
  • Nested command substitution with sensitive paths -- blocked

Multi-Tool Ignore Support

Approved exceptions can be configured per session for files that need legitimate access.

When to Use

  • Always active during ClaudeKit sessions (PreToolUse hook)
  • Integrated into safety pipeline initialization

Processes Used By

  • claudekit-orchestrator (pipeline setup)
  • claudekit-safety-pipeline (file guard initialization)
