Get to know the code
Understand unfamiliar code
with evidence.
Explore how a repository works, follow its call paths, and inspect the source behind each explanation.
No account or API key needed for the example.
Start with a question
Now explore your own repository.
Turn a public GitHub repository into a navigable Wiki with explanations and source references. Keep reading as chapters finish, then return to your saved link.

Take that context to your coding agent.
Build a local index for Claude Code or Codex. Find definitions, follow callers and read the source in your own checkout.
python -m pip install "codenib[graph,mcp]"
codenib codegraph init /path/to/your/repoPython 3.10+, Git, a clean checkout, and Claude Code or Codex. This shipping CodeGraph path runs locally without a model, API key, or GPU for CodeNib; your agent uses its own model. It is separate from the grep/Jev experiment.
Setup and language prerequisites · Ask your agent to start with explore_context.
Evidence you can inspect. Tools you can compare.
Follow source locations, check language coverage, and reproduce the retrieval methods.
Follow definitions and calls
Bounded context and typed SCIP/LSP graphs help your agent navigate from a question to the source. Compare the fit with grep, Serena, CodeGraph, and DeepWiki.
