SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill eliminates the time-consuming guesswork of figuring out how an unfamiliar codebase is organized and how its pieces fit together, so you can produce accurate, user-friendly documentation quickly.

Core Features & Use Cases

  • Codebase analysis into documentation: Scans for entry points, project metadata, structure, tech stack, and existing docs to avoid duplication.
  • Generates multiple documentation types from a template: Produces READMEs, architecture docs, API references, ADRs (using the provided reference format), inline code comments, and onboarding/contribution materials.
  • Guided “review before publishing” quality pass: Ensures setup steps are complete and testable, code examples reference real files, and the output is scannable with clear structure.

Core use cases: onboarding a new contributor, documenting a feature after refactors, answering “how does this codebase work?” even without the word documentation, and creating consistent project docs across modules and languages.

Quick Start

Tell the AI: “Use codebase-documenter to create a beginner-friendly README for this repository, including a quick-start section and a documented project structure tree.”

Frequently Asked Questions about codebase-documenter

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

FAQPage Schema
How do I generate a README and architecture overview from an existing codebase?▼

To generate a README and architecture overview, the codebase is analyzed for entry points, project metadata, structure, and tech stack to produce beginner-friendly, cross-linked documentation that avoids duplicating existing docs.

What is the best way to document a codebase for new contributor onboarding?▼

Documenting a codebase for onboarding involves scanning the project structure and tech stack to generate contribution guides, runbooks, and code walkthroughs that explain how the pieces fit together with testable setup steps.

Can I generate API references and ADRs without duplicating my existing documentation?▼

Yes, API references and ADRs can be generated without duplication by scanning existing docs and project metadata first, then applying matching templates to produce accurate, cross-linked architecture decision records and reference material.

How do I write inline code comments and walkthroughs for an unfamiliar project structure?▼

Writing inline code comments and walkthroughs requires analyzing the project's entry points and structure, then generating explanations that reference real files and provide a scannable, beginner-friendly review of the codebase logic.

Does codebase documentation generation work for multiple modules and programming languages?▼

Yes, codebase documentation generation works across modules and languages by scanning project metadata and structure to create consistent documentation, though a review checklist ensures completeness and testable setup steps for each specific tech stack.

What should I check before publishing generated project documentation?▼

Before publishing generated project documentation, you should run a guided review pass to ensure setup steps are complete and testable, code examples reference real files, and the output structure is scannable and clear.
