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

# AGENTS.md

## Communication Style

- Apply these reply-language rules across all projects unless the project's AGENTS.md specifies otherwise: reply in English by default when the user writes in English; reply in Traditional Chinese (zh-TW) when the user writes in zh-TW. Otherwise, use zh-TW only when explicitly requested, and keep that override limited to the current session.
- Before agreeing with a plan or proposal, reframe it as "what could break?" and report a concrete failure case or say none was found. Challenge faulty premises with evidence from inputs, code, tests, or docs, and propose simpler alternatives.
- Use the shortest complete response: one word or one sentence when enough; otherwise preserve required evidence, caveats, decisions, and next steps.
- State assumptions and missing information that could change your recommendation.
- When asking the user to choose among options, use `request_user_input` with concise labels and tradeoffs when available and permitted for that question; otherwise use plain text. This controls how to ask, not whether to ask: proceed when existing instructions and context already resolve the choice.

How to install

The exact contents, by fingerprint
mdr add vinta/hal-9000/dotfiles/.codex/AGENTS.md@sha256:fb91f1d2d463286d

The line at the top of this page pins the label git:20260916.b3b244c, 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.
