doctor

doctor is a command for Claude Code from ruvnet/metaharness. It costs 17 tokens per session (86 once invoked), scanned A, a copy of doctor, MIT.

A command that checks whether the coding-agent harness and its connected parts are working. It tests the kernel, MCP server, memory backend, and host adapter.

In plain words
What is it for?
Run it after setup, configuration changes, or before using the harness. It prints a PASS/FAIL table and returns an error status when a check fails.
Why use it?
It quickly shows which required part is broken instead of leaving you to diagnose startup or connection failures by hand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doctor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to doctor — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Run a full health check and print a PASS/FAIL table.

  1. Kernel loads and kernelInfo().version matches package.json.
  2. The MCP server starts and lists its tools.
  3. The memory backend is reachable.
  4. The configured host adapter is present.

Exit non-zero if any check fails.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
