--- name: Hooks Automation description: Automated coordination, formatting, and learning from Claude Code operations using intelligent hooks with MCP integration. Includes pre\/post task hooks, session management, Git integration, memory coordination, and neural pattern training for enhanced development workflows. --- # 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) -

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 ``` ```bash # 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 ```javascript \/\/ .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 }, }); \/\/ Return decision if (complexity > 15 || securityIssues.length > 0) { return { continue: false, reason: 'Quality checks failed', warnings: [ `Complexity: ${complexity} (max: 15)`, `Security issues: ${securityIssues.length}`, ], }; } return { continue: true, reason: 'Quality checks passed', metadata: { complexity, securityIssues: 0 }, }; }, }; ``` #### Register Custom Hook ```json { "hooks": { "PreToolUse": [ { "matcher": "^(Write|Edit)$", "hooks": [ { "type": "script", "script": ".claude\/hooks\/custom-quality-check.js" } ] } ] } } ``` ### Real-World Examples #### Example 1: Full-Stack Development Workflow ```bash # Session start -
