name	analyze-codebase
description	Generate comprehensive codebase analysis covering architecture, security, performance, and code quality. Use when user says 'analyze codebase', 'code audit', 'architecture review', or 'project health check'.

Analyze Codebase

When to Use

• Onboarding new developers
• Architecture documentation
• Project health assessment
• Before major refactoring
• Understanding system complexity

Analysis Process

Step 1: Discovery

# Project structure
tree -L 3 -I 'node_modules|.next|dist|build|coverage'

# File counts
find . -type f -name "*.ts" | wc -l
find . -type f -name "*.tsx" | wc -l

Step 2: Architecture Analysis

• Identify modules, entry points, API structure
• Map frontend components and routing
• Document service patterns and conventions

Step 3: Patterns and Standards

• Check for established patterns in docs/examples
• Analyze type system organization
• Review security patterns (auth, multi-tenancy, soft delete)

Step 4: Dependencies

• Catalog external services and libraries
• Check version currency
• Identify critical dependencies

Step 5: Generate Report

Write to .agents/memory/codebase-analysis.md with these sections:

1. Executive Summary — 3-5 sentence overview
2. Project Overview — Tech stack, purpose, architecture style
3. Directory Structure — Module layout and organization
4. Architecture Patterns — Backend and frontend patterns
5. Security Analysis — Auth, data isolation, validation
6. Performance Insights — Database, caching, background jobs
7. Code Quality — Strengths, improvements, tech debt
8. Dependencies — Critical packages and version matrix
9. Testing Strategy — Coverage, patterns, gaps
10. Recommendations — Immediate, short-term, long-term

Quick Mode

For faster analysis (skip detailed metrics):

tree -L 3 -I 'node_modules|.next|dist'
echo "TypeScript: $(find . -name '*.ts' -o -name '*.tsx' | wc -l)"
echo "Controllers: $(find . -name '*.controller.ts' | wc -l)"
echo "Services: $(find . -name '*.service.ts' | wc -l)"
