mcp-doctor: Instructions file for Codex

AGENTS.md

mcp-doctor AGENTS.md is an instructions file for Codex, OpenCode from Coefficient-work/mcp-doctor. It costs 736 tokens per session, scanned A, original, MIT.

An instruction guide for the Coefficient-work/mcp-doctor repository. It covers choosing between Codex and Cursor, using a remote API for Gmail and Google files, and fetching files between Macs.

In plain words
What is it for?
Use it when working in mcp-doctor, especially for agent-routing decisions, Gmail or Google file operations, remote Mac file retrieval, and related setup or troubleshooting.
Why use it?
It prevents agents from choosing the wrong coding workflow or using prohibited access methods for email and Google Drive, Sheets, or Docs. It also documents the approved route for files stored on another machine.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Codex.

This is Coefficient-work/mcp-doctor's own configuration. It tells Codex and OpenCode how to work on mcp-doctor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-doctor configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/louisreid/Documents/tars/scripts/install-codex-vs-cursor-skill.sh.

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

mcp-doctor AGENTS.md 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 2mo 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.

Codex vs Cursor (agent routing)

Use the codex-vs-cursor skill when choosing the coding agent for a job:

  • Cursor — daily IDE (UI, Flutter, Payload admin, TARS ops, fuzzy explore/debug, live diffs)
  • Codex — walk-away / async (scoped migrations, schema PRs, batch fixes, large refactors → PR)

Skill: .cursor/skills/codex-vs-cursor/SKILL.md · re-install: bash /Users/louisreid/Documents/tars/scripts/install-codex-vs-cursor-skill.sh

Prompt: Use codex-vs-cursor. Job: … Repo: … Interactive now or walk-away PR?

TARS remote API (Gmail / Drive / Sheets) — mandatory

Always use tars-remote-api for Louis’s Gmail, Miriam’s Gmail (account:"mim" → [email protected]), and Google Drive/Sheets/Docs via Mac mini :3049. Do not use Cursor plugin-gmail / plugin-google-drive or local Google OAuth in this repo.

Skill: .cursor/skills/tars-remote-api/SKILL.md Re-install: bash /Users/louisreid/Documents/tars/scripts/install-tars-remote-api-skill.sh

Cursor secrets (Cloud Agent only): REID_REMOTE_TOKEN, MAC_MINI_HOST, TAILSCALE_AUTH_KEY — not injected in Build Locally.

Preflight: bash /Users/louisreid/Documents/tars/scripts/tars-remote-preflight.sh

Hub: tars cross-repo bridge · google-api README

Prompts:

  • Use tars-remote-api skill. Run preflight, then search Gmail …
  • Use tars-remote-api skill. Run preflight. Search Mim Gmail (account:mim) …
  • Use tars-remote-api skill. Run preflight. Search Drive … (not the Drive plugin)

Cross-machine file fetch (Mini ↔ Air)

When a path is on the other Mac (Mini ↔ Air), use skill cross-machine-fetch (~/.cursor/skills/cross-machine-fetch · .cursor/skills/cross-machine-fetch).

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.
