Hookify Command

Creates custom behavioral rules to prevent unwanted actions.

When To Use

Use this command when you need to:

• Creating rules from explicit instructions
• Analyzing conversation for unwanted behaviors to block

When NOT To Use

• Complex multi-step workflows - use agents instead
• One-time operations that don't need persistent rules

Usage

Create Rule from Instruction

/hookify Don't use console.log in TypeScript files

This will: 1. Parse your instruction 2. Determine appropriate event type (bash, file, etc.) 3. Generate regex pattern 4. Create rule file in `.claude/` 5. Enable rule immediately

Analyze Conversation

/hookify

Without arguments, hookify will: 1. Analyze recent conversation history 2. Identify unwanted behaviors or mistakes 3. Suggest rules to prevent recurrence 4. Ask if you want to create them

Rule Creation Flow

1. **Event Detection**: Determines which tool the rule applies to 2. **Pattern Generation**: Creates regex pattern from your description 3. **Action Selection**: Chooses warn or block based on severity 4. **Message Creation**: Generates helpful message for Claude 5. **File Creation**: Saves to `.claude/hookify.{name}.local.md`
