CLAUDE.md claudeB
CLAUDE.md is agent-read markdown (claude) from pku-yuangroup/openai4s.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# CLAUDE.md / AGENTS.md This file provides shared guidance to both Claude Code (`CLAUDE.md`) and Codex (`AGENTS.md`, symlinked to this file) when working with code in this repository. Keep future guidance platform-neutral unless a section explicitly calls out a Claude Code- or Codex-specific workflow. ## What this is **OpenAI4S** is a pure-stdlib hybrid scientific research agent: provider-native JSON `Tool` calls form the orchestration/permission control plane, while persistent Python/R Code-as-Action kernels form the scientific execution plane. Python can call the in-kernel `host` singleton synchronously mid-cell; R is an independent analysis channel. **Core is zero-dependency by design.** The engine, the LLM client (over `urllib`), and the web server (`http.server` + a hand-rolled WebSocket) use only the Python standard library. This is a hard constraint — see conventions below. ## Commands ```bash ./setup.sh # one-time: locked lightweight .venv + pre-commit hook ./setup.sh --with-kernel-envs # also create comprehensive Python + R envs ./setup.sh --update-kernel-envs # sync existing Python + R envs, without pruning …

How to install
mdr add pku-yuangroup/openai4s/CLAUDE.md@git:20260916.bb0d860mdr add pku-yuangroup/openai4s/CLAUDE.md@sha256:3d4e6036932d45f6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
