Deep Codebase Reading: 6 Skills for Call Chains and Architecture
From digging through files by hand to instant call chains, generated diagrams, and a risk report

What Stops You From Deep-Reading a Codebase Is Not IQ — It Is Method
There is just too much code. I read two files and I am already falling asleep.
source: rednote · source-code breakdown method post observation
I inherited a legacy repo with zero documentation and no clue where the entry point even is.
source: rednote · AI-drawn repo map post observation
I do not want to learn the framework by hard-reading source. Give me a map first, then I will pick the three files worth reading.

FAQ
Q: What is the right order for deep-reading a codebase?
A: Build the big picture with github-code-interpreter, trace key call chains with codegraph, generate diagrams with source-to-architecture when you need to present, and run deep-code-analyzer for a full risk review before adopting or taking over a project.
Q: Does codegraph need extra setup?
A: It needs Node 20+ and the codegraph CLI. After you send the install command, the Agent walks you through the dependencies; once the repo is indexed you can query call chains in natural language.
Q: Which languages are supported?
A: codegraph is built on tree-sitter and covers mainstream languages. source-to-architecture currently supports Python, JS, TS, and Java. The other Skills are Agent-driven static analysis with no hard language limits.
Q: How long does indexing a large repo take?
A: In a community test, codegraph indexed a 90-file project in under a second. Bigger repos take longer, but indexing is a one-time cost — every query after that comes back instantly.
Q: Can I analyze private company code?
A: Yes. Tools like codegraph and code-knowledge-graph parse locally, and code-understanding-diagrams scans offline as well, so your code never leaves your environment.
Q: Where does Deep Skill Finder fit in?
A: You just say "help me deep-read this repo", and it matches Skills for call chains, architecture diagrams, and risk reviews from MEYO's 50,000+ Skill library — no trial and error on your side.
