ABOUTME: Automated codebase analysis and CLAUDE.md generation
ABOUTME: Project structure mapping, convention detection, documentation creation
Project Analyzer
Analyzes a codebase via a specialized agent (Haiku) that generates comprehensive CLAUDE.md documentation.
When to Use
- Starting work on a new project
- Need to understand project structure
- Creating/updating project documentation
Agent Invocation
Use the Task tool with:
subagent_type: "project-analyzer"
prompt: "Analyze the project in [directory] and create comprehensive CLAUDE.md documentation"The agent will:
- Scan directory structure
- Identify language and framework
- Analyze code patterns with ast-grep
- Detect conventions
- Generate CLAUDE.md
Language Detection
| Indicator File | Language/Framework | Key Config Files |
|---|---|---|
go.mod |
Go | go.sum, Makefile |
pyproject.toml |
Python | uv.lock, setup.py, .python-version |
Gemfile |
Ruby/Rails | Gemfile.lock, config/routes.rb |
Package.swift |
Swift | .xcodeproj, .xcworkspace |
build.gradle.kts |
Kotlin/Android | settings.gradle.kts, AndroidManifest.xml |
package.json |
Node/React | next.config.*, tsconfig.json |
*.tf |
Terraform | *.tfvars, terragrunt.hcl |
Cargo.toml |
Rust | Cargo.lock |
docker-compose.yml |
Docker | Dockerfile, .dockerignore |
Also check: .gitignore, .env.example, .github/workflows/*.yml, .gitlab-ci.yml, Jenkinsfile
Quality tools: .golangci.yml (Go), ruff.toml (Python), .rubocop.yml (Rails), .eslintrc (JS)
Framework Detection
| Pattern | Framework |
|---|---|
config/routes.rb |
Rails |
next.config.* |
Next.js |
angular.json |
Angular |
nuxt.config.* |
Nuxt |
fastapi in deps |
FastAPI |
django in deps |
Django |
gin or echo in go.mod |
Go web |
Vapor in Package.swift |
