One thing to look at

1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Auto-generate onboarding documentation from codebase analysis, tailored to the reader's experience level. TRIGGER when: user asks to onboard someone to a codebase, document this codebase, generate project documentation for new team members, write a codebase walkthrough or tour, create a getting-started guide, or explain a codebase to a specific audience. DO NOT TRIGGER when: user wants API reference docs (use language-specific tooling), or wants to understand a single file (just read it).

codebase-onboarding

Auto-generate onboarding documentation from codebase analysis. Audience-aware output for junior developers, senior engineers, and contractors.

What You Get

Architecture overview derived from actual code structure
Key entry points and control flow
Testing strategy and deployment process
Domain glossary extracted from code and comments
Audience-tailored depth and focus

Workflow

Analyze -- Scan the codebase to discover stack, structure, and patterns
Capture signals -- Identify entry points, config files, CI/CD, test patterns, dependency graph, domain terms
Fill template -- Populate the output format sections
Tailor -- Adjust depth and emphasis for the target audience

Analysis signals

Signal	Where to look
Language/framework	package.json, mix.exs, go.mod, Cargo.toml, pyproject.toml
Entry points	main files, router definitions, CLI entry points
Config	.env.example, config/, settings files
CI/CD	.github/workflows/, Makefile, Dockerfile
Tests	test/, spec/, tests/, *_test.go
Database	migrations/, schema files, ORM models
API surface	OpenAPI specs, GraphQL schema, route definitions
Domain terms	README, doc comments, module names, type names
Dependencies	Lock files, vendor/, package manifests
Dev setup	Makefile, docker-compose.yml, devcontainer.json

Rules

Derive everything from the actual codebase -- do not fabricate
Flag gaps explicitly ("No CI/CD configuration found")
Keep the glossary to terms a newcomer would not know
Link to actual files using relative paths
If the audience is not specified, ask before generating

Reference

File	Topic
audience-profiles.md	Junior/Senior/Contractor focus areas
output-template.md	Markdown template for the onboarding doc
