What problem does it solve?

Analyze unfamiliar codebases to generate a structured onboarding guide with architecture map, key entry points, conventions, and a starter CLAUDE.md. Use when joining a new project or setting up Claude Code for the first time in a repo.

Core Features & Use Cases

Reconnaissance-driven assessment to identify language, frameworks, entry points, and main components.
Architecture mapping and data-flow sketch to visualize how parts connect.
Convention detection for naming, testing, and Git workflows, with actionable recommendations.
Output generation of an onboarding guide and a starter CLAUDE.md to bootstrap project setup.

Quick Start

Supply a repository to analyze and run the onboarding workflow to generate a detailed guide and a starter CLAUDE.md.

FAQPage Schema

How do I create an onboarding guide for an unfamiliar codebase?▼

Codebase onboarding involves analyzing a repository to map its architecture, identify key entry points, detect conventions, and generate a structured guide with a starter CLAUDE.md to bootstrap new developers.

What is the best way to map architecture and data flow in an existing repository?▼

Mapping architecture and data flow requires reconnaissance-driven assessment of the codebase to identify main components, sketch connections, and visualize how data moves across the system.

Can I automatically detect coding conventions for naming, testing, and Git workflows?▼

Yes, convention detection analyzes the codebase to identify naming patterns, testing frameworks, and Git workflows, then provides actionable recommendations to align with project standards.

How do I set up Claude Code for the first time in an existing codebase?▼

To set up Claude Code in an existing codebase, analyze the repository to detect its tech stack and architecture, then generate a starter CLAUDE.md file to bootstrap project configuration.

Does codebase analysis work for identifying the tech stack and main entry points?▼

Yes, codebase analysis performs reconnaissance to identify the programming language, frameworks, key entry points, and main components, enabling fast understanding of unfamiliar repositories.

When should I use an automated codebase guide instead of manual exploration?▼

Use an automated codebase guide when onboarding new developers, joining a project, or setting up Claude Code, replacing manual architecture and convention discovery with generated structured documentation.
