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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00303 | $0.00303 |
| Opus 5 | $0.00151 | $0.00151 |
| Sonnet 5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
mcp-server 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 yesterday.
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
AGENTS.md
Instructions for any AI coding agent working in this repository (Codex, Claude, Cursor, Gemini, and others). Project-specific truth lives here so a fresh agent is never guessing.
What this is
A small plug-in that lets AI assistants (Claude, Cursor, etc.) look up golf courses and write golf data back to OpenGolfAPI — "find courses near Chicago", "score this round", "sign this golfer up". It is published to npm as @opengolfapi/mcp-server; users add six lines to their AI client's config and get 56 golf tools. It is a thin client: it contains no golf data and no database. Every tool is a hand-written HTTP call to https://api.opengolfapi.org, which lives elsewhere.

Working here
- Always open a pull request; never push straight to the default branch. Other people and agents work in these repos.
- Verify a claim against the running system before repeating it. A number in a doc without a date and a method is a rumour.
- Match the surrounding code's style and conventions.
- On start, read
.gstack/inbox.mdfor messages and proposals from G-Stat (the cross-project advisor). Act on or reply to anything addressed to this repo.
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.

mcp-server AGENTS.md is an instructions file published in the GitHub repository opengolfapi/mcp-server (4 stars, last pushed 14d ago), licensed MIT. It adds 303 tokens to every session, about $0.0015 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
