💡 Best Practices

When to Enable Hooks

Always Enable:

component-validation.sh - Prevents malformed components
standards-compliance.sh - Ensures quality and security
pre-push-submodule-check.sh - Critical for distributed repos

Recommended:

documentation-sync.sh - Automatic documentation updates
quality_gate_enforcement.py - Commit quality enforcement
monitoring_observability.py - System health visibility

Optional (Development):

performance_optimization.py - Code quality suggestions
dependency_management.py - Dependency tracking
performance_profiling.py - Hook performance analysis

Performance Considerations

Critical Path (Blocking Hooks):

Component validation: <50ms
Standards compliance: <100ms
Total blocking overhead: <300ms

Background (Non-Blocking Hooks):

Documentation sync: <200ms
Quality checks: <1s
Monitoring: <50ms
Total background overhead: <2s (parallel execution)

Tips:

Use absolute paths for reliability
Increase timeout for slow systems
Disable hooks temporarily with SKIP_HOOKS=1
Monitor hook performance with monitoring_observability.py

Security Considerations

Secrets Management:

Never commit API keys, tokens, credentials
Use environment variables for configuration
standards_compliance.py detects hardcoded secrets

Safe Operations:

Hooks run in sandboxed environment
No network access by default
File operations limited to repository

Audit Trail:

All hook executions logged
Quality reports saved to repository
Monitoring metrics tracked

🔧 Troubleshooting

Hook Not Executing

Symptom: Hook doesn't run when expected Solution:

Verify hook path is correct (use absolute paths)
Check hook script is executable: chmod +x hooks/*.sh
Verify matcher regex matches your tool usage
Check Claude Code settings are saved properly

# Test hook manually

Hook Timing Out

Symptom: Hook runs but times out Solution:

Increase timeout in settings: "timeout": 60 (default is 30)
Check for blocking operations in hook script
Verify system resources are available
Review performance profiling report

Blocking Hook Issues

Symptom: Operations unexpectedly blocked Solution:

Check the rejection message in tool output
Review hook logic for false positives
Temporarily disable hook to verify: SKIP_HOOKS=1
Adjust validation thresholds

# Disable hook temporarily
export SKIP_HOOKS=1
# Run operation
# Re-enable
unset SKIP_HOOKS

Performance Degradation

Symptom: Hooks running slower over time Solution:

Check performance profiling report: .performance-profile-report.txt
Review monitoring report: .hook-monitoring-report.txt
Clear old metrics: rm .hook-metrics-*.json
Optimize slow hooks based on profiling data

🧠 Continual Learning Hooks

18. session-retrospective.py

Purpose: Automated session retrospective for continual skill optimization Event: PostSession / Manual Blocking: ❌ No Lines of Code: 650+ lines

What It Does:

Tracks skill invocations throughout the session
Classifies outcomes (success, partial, failed)
Detects anti-patterns (excessive_retries, context_confusion, etc.)
Calculates skill effectiveness scores
Generates improvement recommendations
Updates skill-learnings.json database

Anti-Pattern Detection:

excessive_retries - Multiple retry attempts indicate unclear instructions
context_confusion - Scope misunderstanding, poor skill boundaries
tool_misuse - Wrong tool selection, weak triggers
incomplete_output - Missing expected elements, needs checklist
hallucination_risk - Ungrounded assumptions, needs verification

Usage:

# Run retrospective
python3 hooks/session-retrospective.py --event session.end

# Real-time optimization
python3 hooks/session-retrospective.py --optimize-now

# Analyze skill learnings
python3 hooks/session-retrospective.py --analyze-skills

Performance:

Execution time: <2s (async, non-blocking)
Storage: skill-learnings.json (<1MB typical)
Integration: SQLite org.db (Tier 2), sessions.db (Tier 3), unified_messages.jsonl

Related:

Command: /optimize-skills, /retrospective
Skill: skill-improvement-tracker
Script: scripts/skill-pattern-analyzer.py

📝 Hook Development Guide

Creating New Hooks

Create Python handler (if needed):

#!/usr/bin/env python3
import json
import sys

try:
    hook_input = json.loads(sys.stdin.read())
    # Process hook input
    print(json.dumps({"continue": True}))
    sys.exit(0)
except Exception as e:
    print(json.dumps({"continue": False, "stopReason": str(e)}))
    sys.exit(1)

Create Bash wrapper:

#!/bin/bash
set -euo pipefail
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
json=$(cat)
python3 "$SCRIPT_DIR/handler.py" < <(echo "$json")
exit $?

Add to settings.json:

{
  "matcher": {"tool_name": "Write"},
  "hooks": [{"type": "command", "command": "bash hooks/new-hook.sh"}]
}

Test hook:

bash hooks/new-hook.sh <<'EOF'
{"event": "PreToolUse", "tool_name": "Write", ...}
EOF
