doctor

A command that checks the Codex plugin environment and reports problems or leftover state that may need attention.

In plain words
What is it for?
Use it to inspect the environment and see remediation hints, including whether the Codex command-line tool is missing or not authenticated.
Why use it?
It helps identify setup issues without installing software, stopping processes, or deleting files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 2d 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.

What it actually says

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" doctor

Operating rules:

  • Return the companion stdout verbatim to the user. Do not paraphrase, summarize, or add commentary.
  • This command never installs anything, never kills processes, and never deletes files. (Loading a corrupt state index triggers the same quarantine-and-rebuild recovery every companion command shares; the rebuilt index is persisted.) Each warning line carries its own remediation hint; leave acting on them to the user.
  • A warning overall status is informational, not a failure — do not escalate it or offer to "fix" anything unless the user asks.
  • If the report shows the codex CLI missing or unauthenticated, point the user at /codex:setup for the guided install flow.
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.
