Pre-Commit Manager Skill

Manage pre-commit hooks with preference memory and template-based configuration.

Operations

1. Install

Install pre-commit hooks in current repository.

Usage:

What it does:

• Checks if .pre-commit-config.yaml exists
• Verifies pre-commit binary is available
• Runs pre-commit install
• Reports success/failure

2. Configure

Generate .pre-commit-config.yaml from templates.

Usage:

Configure pre-commit with python template
Configure pre-commit with javascript template
Configure pre-commit with generic template

Templates:

• python - Python projects (black, ruff, mypy)
• javascript - JS/TS projects (prettier, eslint)
• typescript - TypeScript projects
• generic - Language-agnostic (trailing whitespace, file size, detect-secrets)

3. Enable

Set preference to "always" auto-install.

Usage:

Enable pre-commit auto-install

4. Disable

Set preference to "never" auto-install.

Usage:

Usage:

Show pre-commit status
Check pre-commit status

Shows:

• Git repository status
• Config file existence
• Hooks installation status
• Current preference setting
• Pre-commit binary availability

6. Baseline

Generate .secrets.baseline for detect-secrets.

Usage:

Implementation

This skill interfaces with:

• .claude/tools/amplihack/hooks/precommit_prefs.py - Preference management
• .claude/tools/amplihack/hooks/precommit_installer.py - Hook installation
• Templates in templates/ directory

Security

• Path traversal prevention
• Template whitelist validation
• No shell=True in subprocess calls
• Subprocess timeouts enforced
