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

            "continueOnError": true
          }
        ]
      }
    ]
  }
}

MCP Tool Integration

Hooks automatically integrate with MCP tools for coordination:

Pre-Task Hook with Agent Spawning

// Hook command
npx claude-flow hook pre-task --description "Build REST API"

// Internally calls MCP tools:
mcp__claude-flow__agent_spawn {
  type: "backend-dev",
  capabilities: ["api", "database", "testing"]
}

mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/task/api-build/context",
  namespace: "coordination",
  value: JSON.stringify({
    description: "Build REST API",
    agents: ["backend-dev"],
    started: Date.now()
  })
}

Post-Edit Hook with Memory Storage

// Hook command
npx claude-flow hook post-edit --file "api/auth.js"

// Internally calls MCP tools:
mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/edits/api/auth.js",
  namespace: "coordination",
  value: JSON.stringify({
    file: "api/auth.js",
    timestamp: Date.now(),
    changes: { added: 45, removed: 12 },
    formatted: true,
    linted: true
  })
}

mcp__claude-flow__neural_train {
  pattern_type: "coordination",
  training_data: { /* edit patterns */ }
}

Session End Hook with State Persistence

// Hook command
npx claude-flow hook session-end --session-id "dev-2024"

// Internally calls MCP tools:
mcp__claude-flow__memory_persist {
  sessionId: "dev-2024"
}

mcp__claude-flow__swarm_status {
  swarmId: "current"
}

// Generates metrics and summary

Memory Coordination Protocol

All hooks follow a standardized memory coordination pattern:

Three-Phase Memory Protocol

Phase 1: STATUS - Hook starts

mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/hooks/pre-edit/status",
  namespace: "coordination",
  value: JSON.stringify({
    status: "running",
    hook: "pre-edit",
    file: "src/auth.js",
    timestamp: Date.now()
  })
}

Phase 2: PROGRESS - Hook processes

mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/hooks/pre-edit/progress",
  namespace: "coordination",
  value: JSON.stringify({
    progress: 50,
    action: "validating syntax",
    file: "src/auth.js"
  })
}

Phase 3: COMPLETE - Hook finishes

mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/hooks/pre-edit/complete",
  namespace: "coordination",
  value: JSON.stringify({
    status: "complete",
    result: "success",
    agent_assigned: "backend-dev",
    syntax_valid: true,
    backup_created: true
  })
}

Hook Response Format

Hooks return JSON responses to control operation flow:

Continue Response

{
  "continue": true,
  "reason": "All validations passed",
  "metadata": {
    "agent_assigned": "backend-dev",
    "syntax_valid": true,
    "file": "src/auth.js"
  }
}

Block Response

{
  "continue": false,
  "reason": "Protected file - manual review required",
  "metadata": {
    "file": ".env.production",
    "protection_level": "high",
    "requires": "manual_approval"
  }
}

Warning Response

{
  "continue": true,
  "reason": "Syntax valid but complexity high",
  "warnings": [
    "Cyclomatic complexity: 15 (threshold: 10)",
    "Consider refactoring for better maintainability"
  ],
  "metadata": {
    "complexity": 15,
    "threshold": 10
  }
}

Git Integration

Hooks can integrate with Git operations for quality control:

Pre-Commit Hook

# Add to .git/hooks/pre-commit or use husky

#!/bin/bash
# Run quality checks before commit

# Get staged files
FILES=$(git diff --cached --name-only --diff-filter=ACM)

for FILE in $FILES; do
  # Run pre-edit hook for validation
  npx claude-flow hook pre-edit --file "$FILE" --validate-syntax

  if [ $? -ne 0 ]; then
    echo "Validation failed for $FILE"
    exit 1
  fi

  # Run post-edit hook for formatting
  npx claude-flow hook post-edit --file "$FILE" --auto-format
done

# Run tests
npm test

exit $?

Post-Commit Hook

# Add to .git/hooks/post-commit

#!/bin/bash
# Track commit metrics

COMMIT_HASH=$(git rev-parse HEAD)
COMMIT_MSG=$(git log -1 --pretty=%B)

npx claude-flow hook notify \
  --message "Commit completed: $COMMIT_MSG" \
  --level info \
  --swarm-status

Pre-Push Hook

# Add to .git/hooks/pre-push

#!/bin/bash
# Quality gate before push

# Run full test suite
npm run test:all

# Run quality checks
npx claude-flow hook session-end \
  --generate-report \
  --export-metrics

# Verify quality thresholds
TRUTH_SCORE=$(npx claude-flow metrics score --format json | jq -r '.truth_score')

if (( $(echo "$TRUTH_SCORE < 0.95" | bc -l) )); then
  echo "Truth score below threshold: $TRUTH_SCORE < 0.95"
  exit 1
fi

exit 0

Agent Coordination Workflow

How agents use hooks for coordination:

Agent Workflow Example

# Agent 1: Backend Developer
# STEP 1: Pre-task preparation
npx claude-flow hook pre-task \
  --description "Implement user authentication API" \
  --auto-spawn-agents \
  --load-memory

# STEP 2: Work begins - pre-edit validation
npx claude-flow hook pre-edit \
  --file "api/auth.js" \
  --auto-assign-agent \
  --validate-syntax

# STEP 3: Edit file (via Claude Code Edit tool)
# ... code changes ...

# STEP 4: Post-edit processing
npx claude-flow hook post-edit \
  --file "api/auth.js" \
  --memory-key "swarm/backend/auth-api" \
  --auto-format \
  --train-patterns

# STEP 5: Notify coordination system
npx claude-flow hook notify \
  --message "Auth API implementation complete" \
  --swarm-status \
  --broadcast

# STEP 6: Task completion
npx claude-flow hook post-task \
  --task-id "auth-api" \
  --analyze-performance \
  --store-decisions \
  --export-learnings

# Agent 2: Test Engineer (receives notification)
# STEP 1: Check memory for API details
npx claude-flow hook session-restore \
  --session-id "swarm-current" \
  --restore-memory

# Memory contains: swarm/backend/auth-api with implementation details

# STEP 2: Generate tests
npx claude-flow hook pre-task \
  --description "Write tests for auth API" \
  --load-memory

# STEP 3: Create test file
npx claude-flow hook post-edit \
  --file "api/auth.test.js" \
  --memory-key "swarm/testing/auth-api-tests" \
  --train-patterns

# STEP 4: Share test results
npx claude-flow hook notify \
  --message "Auth API tests complete - 100% coverage" \
  --broadcast

Custom Hook Creation

Create custom hooks for specific workflows:

Custom Hook Template

// .claude/hooks/custom-quality-check.js

module.exports = {
  name: 'custom-quality-check',
  type: 'pre',
  matcher: /\.(ts|js)$/,

  async execute(context) {
    const { file, content } = context;

    // Custom validation logic
    const complexity = await analyzeComplexity(content);
    const securityIssues = await scanSecurity(content);

    // Store in memory
    await storeInMemory({
      key: `quality/${file}`,
      value: { complexity, securityIssues }
    });

Real-World Examples

Example 1: Full-Stack Development Workflow

# Session start - initialize coordination
npx claude-flow hook session-start --session-id "fullstack-feature"

# Pre-task planning
npx claude-flow hook pre-task \
  --description "Build user profile feature - frontend + backend + tests" \
  --auto-spawn-agents \
  --optimize-topology

# Backend work
npx claude-flow hook pre-edit --file "api/profile.js"
# ... implement backend ...
npx claude-flow hook post-edit \
  --file "api/profile.js" \
  --memory-key "profile/backend" \
  --train-patterns

# Frontend work (reads backend details from memory)
npx claude-flow hook pre-edit --file "components/Profile.jsx"
# ... implement frontend ...
npx claude-flow hook post-edit \
  --file "components/Profile.jsx" \
  --memory-key "profile/frontend" \
  --train-patterns

# Testing (reads both backend and frontend from memory)
npx claude-flow hook pre-task \
  --description "Test profile feature" \
  --load-memory

# Session end - export everything
npx claude-flow hook session-end \
  --session-id "fullstack-feature" \
  --export-metrics \
  --generate-summary

Example 2: Debugging with Hooks

# Start debugging session
npx claude-flow hook session-start --session-id "debug-memory-leak"

# Pre-task: analyze issue
npx claude-flow hook pre-task \
  --description "Debug memory leak in event handlers" \
  --load-memory \
  --estimate-complexity

# Search for event emitters
npx claude-flow hook pre-search --query "EventEmitter"
# ... search executes ...
npx claude-flow hook post-search \
  --query "EventEmitter" \
  --cache-results

# Fix the issue
npx claude-flow hook pre-edit \
  --file "services/events.js" \
  --backup-file
# ... fix code ...
npx claude-flow hook post-edit \
  --file "services/events.js" \
  --memory-key "debug/memory-leak-fix" \
  --validate-output

# Verify fix
npx claude-flow hook post-task \
  --task-id "memory-leak-fix" \
  --analyze-performance \
  --generate-report

# End session
npx claude-flow hook session-end \
  --session-id "debug-memory-leak" \
  --export-metrics

Example 3: Multi-Agent Refactoring

# Initialize swarm for refactoring
npx claude-flow hook pre-task \
  --description "Refactor legacy codebase to modern patterns" \
  --auto-spawn-agents \
  --optimize-topology

# Agent 1: Code Analyzer
npx claude-flow hook pre-task --description "Analyze code complexity"
# ... analysis ...
npx claude-flow hook post-task \
  --task-id "analysis" \
  --store-decisions

# Agent 2: Refactoring (reads analysis from memory)
npx claude-flow hook session-restore \
  --session-id "swarm-refactor" \
  --restore-memory

for file in src/**/*.js; do
  npx claude-flow hook pre-edit --file "$file" --backup-file
  # ... refactor ...
  npx claude-flow hook post-edit \
    --file "$file" \
    --memory-key "refactor/$file" \
    --auto-format \
    --train-patterns
done

# Agent 3: Testing (reads refactored code from memory)
npx claude-flow hook pre-task \
  --description "Generate tests for refactored code" \
  --load-memory

# Broadcast completion
npx claude-flow hook notify \
  --message "Refactoring complete - all tests passing" \
  --broadcast

Performance Tips

Keep Hooks Lightweight - Target < 100ms execution time
Use Async for Heavy Operations - Don't block the main flow
Cache Aggressively - Store frequently accessed data
Batch Related Operations - Combine multiple actions
Use Memory Wisely - Set appropriate TTLs
Monitor Hook Performance - Track execution times
Parallelize When Possible - Run independent hooks concurrently

Debugging Hooks

Enable debug mode for troubleshooting:

# Enable debug output
export CLAUDE_FLOW_DEBUG=true

# Test specific hook with verbose output
npx claude-flow hook pre-edit --file "test.js" --debug

# Check hook execution logs
cat .claude-flow/logs/hooks-$(date +%Y-%m-%d).log

# Validate configuration
npx claude-flow hook validate-config

Troubleshooting

Hooks Not Executing

Verify .claude/settings.json syntax
Check hook matcher patterns
Enable debug mode
Review permission settings
Ensure claude-flow CLI is in PATH

Hook Timeouts

Increase timeout values in configuration
Make hooks asynchronous for heavy operations
Optimize hook logic
Check network connectivity for MCP tools

Memory Issues
