Night Market Skill — ported from claude-night-market/hookify. For the full experience with agents, hooks, and commands, install the Claude Code plugin.

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

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

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:

# 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

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
