SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It removes the guesswork and time loss of joining an unfamiliar repository by quickly transforming scattered project signals into a structured onboarding guide and an actionable GEMINI.md.

Core Features & Use Cases

  • Structured codebase onboarding: Produces a concise guide including architecture map, key entry points, directory map, and a request lifecycle walkthrough.
  • Conventions discovery without overload: Uses fast reconnaissance (manifest, config, entry points, tests, and directory snapshots) to infer stack and patterns without reading every file.
  • Starter GEMINI.md generation: Creates or enhances a project-specific GEMINI.md that summarizes tech stack, code style, testing, build/run commands, and conventions.

Quick Start

Ask the AI: "Onboard me to this codebase and generate a project GEMINI.md with architecture map and key conventions."

Frequently Asked Questions about codebase-onboarding

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I onboard to an unfamiliar codebase and understand its architecture quickly?▼

Codebase onboarding quickly transforms scattered project signals into a structured guide covering the architecture map, key entry points, and request lifecycle walkthrough. It uses fast reconnaissance of manifests, configs, and tests to infer patterns without reading every file.

What is the best way to generate a GEMINI.md file for an existing repository?▼

Generating a GEMINI.md file for an existing repository is done by mapping the tech stack, code style, testing, and build commands. The onboarding process analyzes entry points and conventions to produce a project-specific starter file.

Can I discover code conventions and tech stack details without reading every file in the repository?▼

You can discover code conventions without reading every file by using fast reconnaissance of the repository's manifest, configurations, entry points, and directory snapshots. This infers the stack and patterns efficiently to prevent information overload.

How does codebase onboarding map the request lifecycle for a new developer?▼

Mapping the request lifecycle for a new developer involves phased reconnaissance and selective reading of the codebase to trace execution paths. The onboarding guide outputs a clear walkthrough showing requests move through the system's architecture.

Do I need any specific dependencies or components to start onboarding a repository?▼

No specific dependencies or components are required to start onboarding a repository. The process works by analyzing the existing project files, configurations, and directory structure directly to generate the onboarding guide and GEMINI.md.
