Project Analysis Skill

When analyzing a project, systematically gather and present information in this order:

1. Quick Overview (30 seconds)

# Check for common project markers
ls -la
cat README.md 2>/dev/null | head -50

2. Tech Stack Detection

Package Managers & Dependencies

• package.json → Node.js/JavaScript/TypeScript
• requirements.txt / pyproject.toml / setup.py → Python
• go.mod → Go
• Cargo.toml → Rust
• pom.xml / build.gradle → Java
• Gemfile → Ruby

Frameworks (from dependencies)

• React, Vue, Angular, Next.js, Nuxt
• Express, FastAPI, Django, Flask, Rails
• Spring Boot, Gin, Echo

Infrastructure

• Dockerfile, docker-compose.yml → Containerized
• kubernetes/, k8s/ → Kubernetes
• terraform/, .tf files → IaC
• serverless.yml → Serverless Framework
• .github/workflows/ → GitHub Actions

3. Project Structure Analysis

Present as a tree with annotations:

project/
├── src/              # Source code
│   ├── components/   # UI components (React/Vue)
│   ├── services/     # Business logic
│   ├── models/       # Data models
│   └── utils/        # Shared utilities
├── tests/            # Test files
├── docs/             # Documentation
└── config/           # Configuration

4. Key Patterns Identification

Look for and report:

• Architecture: Monolith, Microservices, Serverless, Monorepo
• API Style: REST, GraphQL, gRPC, tRPC
• State Management: Redux, Zustand, MobX, Context
• Database: SQL, NoSQL, ORM used
• Authentication: JWT, OAuth, Sessions
• Testing: Jest, Pytest, Go test, etc.

5. Development Workflow

Check for:

• .eslintrc, .prettierrc → Linting/Formatting
• .husky/ → Git hooks
• Makefile → Build commands
• scripts/ in package.json → NPM scripts

6. Output Format

# Project: [Name]

## Overview
[1-2 sentence description]

## Tech Stack

## Architecture
[Description with simple ASCII diagram if helpful]

## Key Directories
- `src/` - [purpose]
- `lib/` - [purpose]

## Entry Points
- Main: `src/index.ts`
- API: `src/api/`
- Tests: `npm test`

## Conventions
- [Naming conventions]
- [File organization patterns]
- [Code style preferences]

## Quick Commands
| Action | Command |
|--------|---------|
| Install | `npm install` |
| Dev | `npm run dev` |
| Test | `npm test` |
| Build | `npm run build` |
