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

Hookify Rule Catalog

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

Quick Install

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

# Or use the Python installer for bulk operations
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.

Available Rules

git/ - Git Safety

python/ - Python Quality

security/ - Security Gates

performance/ - Resource Management

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:

# 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//.md
2. Copy to .claude/hookify..local.md
3. Edit enabled: true/false as needed
