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

# vibecosystem

This repository contains Claude runtime components and a Codex `luna_worker` adapter.
The default runtime is `core`; `full` is opt-in. Do not treat the number of files in
the repository as the number of components injected into a session.

## Working rules

- Inspect the relevant files and configuration before editing.
- Keep changes within the requested repository and task scope.
- Preserve unrelated user changes and do not expose credentials.
- Do not start swarm, memory, learner, or model-routing automation unless explicitly requested.
- The Codex worker uses `gpt-5.6-luna` with `max` reasoning. Project config must not override it.
- Claude-only `opus` and `sonnet` metadata must not be used by Codex.
- Prefer the smallest complete change and run focused verification afterward.
- Stop before destructive actions, external messages, or irreversible migrations that were not requested.

## Validation

For hook changes run `cd hooks && npm run check && npm test`.
For installer or config changes run the dry-run path with a temporary HOME and parse all JSON/TOML.
Report changed paths, checks performed, and unresolved caveats.

How to install

The exact contents, by fingerprint

mdr add vibeeval/vibecosystem/AGENTS.md@sha256:a6af64ffcb1a42fe

The line at the top of this page pins the label git:20260808.3b763b1, 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.
