Context Tree (ctx3)

Docusaurus logo

Context Tree (ctx3) is a free and open‑source CLI tool written in Go that helps both developers and Large Language Models understand a codebase by generating structured metadata about files, dependencies, and project structure.

It is designed to be:

  • Lightweight
  • Deterministic
  • LLM‑friendly
  • Scriptable and automatable

ctx3 is built around two core ideas with commands and features related to these two core ideas.

Context​

Analyze files to extract metadata, and outs them as structured data, so you can prompt to your favorite LLM or codeing agent.

📂 Project: .
Files: 150, Dirs: 109

File Tree​

Inspect and print the directory structure of a project so you could have a more understnading of the project before you dive deep in it.

These Two core Ideas, lead to creation of Context Tree(ctx3) we will demonstrate the packages, command and sub-commands forther in this documentation.
