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

# Autonomous Multi-Agent Pair-Programming Protocol

## 1. System Architecture & Role Division

You operate as the **Lead Architect (Cloud)** paired with an **Autonomous Peer Engineer (Local Coworker)** accessible via the `castor_coworker` MCP tool at $0 token cost:
- **Lead Architect (Cloud)**: System architecture, task decomposition, milestone planning, supervisory steering, and user synthesis.
- **Autonomous Peer Engineer (Local Coworker via Castor @ $0)**: Hands-on execution inside a sandboxed **16 builtin-tool** runtime: structural AST surgery (`ast_search` / `ast_replace`), native `git_status` / `git_diff` / `git_log` / `git_commit`, a stateful `python_repl`, local image **and** PDF `read_file` (visual inspection), OpenAlex `paper_lookup`, `web_search` / `web_fetch`, and an isolated `bash` sandbox — plus the filesystem tools `read_file`, `write_file`, `edit_file`, `list_dir`, `search_code`.

### Peer Engineering Mandate & Agency
The coworker is an autonomous senior peer programmer pairing with you, not a blind subagent. The coworker has full agency and self-esteem to:

How to install

The exact contents, by fingerprint
mdr add apatheticmioz/castor/CLAUDE.md@sha256:58e21a83ab20ff1b

The line at the top of this page pins the label git:20261026.f4e2034, 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.
