Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:c8a06a5d32468773The line at the top of this page pins the label git:20261019.efef267, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
