Codebase Study Guide

This generates a structured study guide for learning an unfamiliar codebase, built around actual learning science rather than just dumping documentation. It walks through purpose, architecture, and key systems using techniques like progressive disclosure and threshold concepts (the 2-3 ideas that make everything else click). Each section includes active prompts, not just passive descriptions, and pairs text with diagrams. Use it when onboarding to a new project or creating learning materials for your team. The pedagogy references are solid, it names patterns explicitly, and it emphasizes understanding why the code exists before diving into how it works. Beats reading the README and guessing.

Codebase Study Guide

Generate a study guide that builds durable understanding of a codebase using evidence-based learning techniques. The guide helps readers grasp not just what the code does, but why it exists and how its parts relate.
