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/<category>/<rule>.md
2. Copy to .claude/hookify.<rule-name>.local.md
3. Edit enabled: true/false as needed
