Powered by Octocode🐙

The missing manual for AI CLI tools.
Deep-dive documentation, implementation secrets, and architecture internals extracted directly from source code.


For developers, researchers, and power users who need to look under the hood. Official documentation tells you what a tool does. We show you how it works, what's undocumented, and how to build on top of it.

💡 Why this exists

Open source doesn't always mean well-documented. Critical details are often buried in code. We extract:

  • 🛠️ Internals & Architecture — How the systems are actually built
  • 🧩 Undocumented Features — Hidden APIs, beta functionality, and system prompts
  • ⚠️ Real-world Gotchas — Edge cases, security models, and implementation constraints
  • 🔌 Integration Patterns — How to properly interface with these agents
