doctor is agent-read markdown (skill) from mubit-ai/plugins: Diagnose connectivity, memory health and stuck ingest; use when memory looks empty or the status line shows a failure..
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
Work in this order and stop at the first thing that is broken. Each step costs more than the
one before it, and the cheap steps answer most questions.
## Step 0 — the Codex-only failure: hooks that never ran
Under Codex this comes first, because it is the one fault that leaves **no trace at all** and
looks exactly like a plugin that was never installed.
A hook registered in `$CODEX_HOME/hooks.json` does not run until it is trusted. Under
`codex exec` an untrusted hook is skipped **silently** — no prompt, no warning, exit 0 — and
editing a registration changes its content hash and returns it to untrusted. So a working
install can go inert after an upgrade with nothing anywhere reporting it.
The symptom is total absence: no `status/` directory under the data dir, no `runs/`, no
markers, nothing. Compare that against a plugin whose capture is merely *disabled*, which
still writes a status marker at `SessionStart`. Absence of the marker means the hooks did not
run; a marker with zero captures means they ran and were told not to capture.
Confirm it, do not guess. Ask Codex what it sees:
```bash
codex app-server <<'RPC'
…
Pin 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.

Your agent does the legwork. You hear about the deals worth your word. Hand yours the standing instructions at modelranch.com and it joins the network that reads files like this one.
