Hooks Automation

Intelligent automation system that coordinates, validates, and learns from Claude Code operations through hooks integrated with MCP tools and neural pattern training.

What This Skill Does

This skill provides a comprehensive hook system that automatically manages development operations, coordinates swarm agents, maintains session state, and continuously learns from coding patterns. It enables automated agent assignment, code formatting, performance tracking, and cross-session memory persistence.

Key Capabilities:

• Pre-Operation Hooks: Validate, prepare, and auto-assign agents before operations
• Post-Operation Hooks: Format, analyze, and train patterns after operations
• Session Management: Persist state, restore context, generate summaries
• Memory Coordination: Synchronize knowledge across swarm agents
• Git Integration: Automated commit hooks with quality verification
• Neural Training: Continuous learning from successful patterns
• MCP Integration: Seamless coordination with swarm tools

Prerequisites

Required:

• Claude Flow CLI installed (npm install -g claude-flow@alpha)
• Claude Code with hooks enabled
• .claude/settings.json with hook configurations

Optional:

• MCP servers configured (claude-flow, ruv-swarm, flow-nexus)
• Git repository for version control
• Testing framework for quality verification

Quick Start

Initialize Hooks System

# Initialize with default hooks configuration
npx claude-flow init --hooks

This creates:

• .claude/settings.json with pre-configured hooks
• Hook command documentation in .claude/commands/hooks/
• Default hook handlers for common operations

Basic Hook Usage

# Pre-task hook (auto-spawns agents)
npx claude-flow hook pre-task --description "Implement authentication"

# Post-edit hook (auto-formats and stores in memory)
npx claude-flow hook post-edit --file "src/auth.js" --memory-key "auth/login"

# Session end hook (saves state and metrics)
npx claude-flow hook session-end --session-id "dev-session" --export-metrics
