## When To Use

- Browsing available hookify rules by category
- Installing standard pre-built rules into a project
- Looking for ready-made rules before writing custom ones

## When NOT To Use

- Writing custom rules from scratch: use `hookify:writing-rules` instead
- Debugging or modifying existing installed rules
- Converting Python SDK hooks: use `hookify:from-hook` instead

# Hookify Rule Catalog

Pre-built rules for common scenarios. Install directly or use as templates.

## Quick Install

```bash
# Install a specific rule
Skill(hookify:rule-catalog) then install git:block-force-push

python3 plugins/hookify/scripts/install_rule.py git:block-force-push
python3 plugins/hookify/scripts/install_rule.py --category git
python3 plugins/hookify/scripts/install_rule.py --all
```
**Verification:** Run `python --version` to verify Python environment.

## Installation Instructions

### Method 1: Claude-Assisted (Recommended)

When you invoke this skill, tell Claude which rule(s) to install:

```
**Verification:** Run `git status` to confirm working tree state.
Install git:block-force-push
```
**Verification:** Run the command with `--help` flag to verify availability.

Claude will:
1. Read the rule from `skills/rule-catalog/rules/git/block-force-push.md`
2. Write it to `.claude/hookify.block-force-push.local.md`
3. Confirm installation

### Method 2: Python Script

For bulk operations or automation:

```bash
# Install single rule
python3 plugins/hookify/scripts/install_rule.py git:block-force-push

# Install all rules in category
python3 plugins/hookify/scripts/install_rule.py --category python

# Install all rules
python3 plugins/hookify/scripts/install_rule.py --all

# List available rules
python3 plugins/hookify/scripts/install_rule.py --list

# Install to custom directory
python3 plugins/hookify/scripts/install_rule.py git:block-force-push --target /path/to/.claude
```
**Verification:** Run the command with `--help` flag to verify availability.

### Method 3: Manual Copy

1. Find rule in `plugins/hookify/skills/rule-catalog/rules/<category>/<rule>.md`
2. Copy to `.claude/hookify.<rule-name>.local.md`
3. Edit `enabled: true/false` as needed
