Guidance for Claude Code (and any other agent) working in this repository. Pooprusteek is a Rust TUI coding agent that talks to DeepSeek's reverse-engineered web API (no paid API key — cookie/token auth, local SHA-3 proof-of-work) instead of an official LLM API, with optional extra providers (OpenAI-compatible / Anthropic Messages / Gemini endpoints via /providers).

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
