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

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

# 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.

Installation Instructions#

Method 1: Claude-Assisted (Recommended)#

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

text

**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

Rule File Locations#

Rules are stored relative to this skill:

Customizing Rules#

After installation, edit the rule in .claude/:

yaml

# Change action from warn to block
action: block

# Disable temporarily
enabled: false

# Modify pattern
pattern: your-custom-pattern

Verification: Run the command with --help flag to verify availability.

Creating Pull Requests for New Rules#

To add rules to the catalog:

1. Create rule file in appropriate category
2. Follow naming convention: kebab-case.md
3. Include detailed message with alternatives
4. Test thoroughly before submitting
5. Update this SKILL.md catalog table
