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 5.1 | $0.01322 | $0.01322 |
| Opus 5.5 | $0.00529 | $0.00529 |
| Sonnet 5.5 | $0.00264 | $0.00264 |
| Haiku 4.5 | $0.00132 | $0.00132 |
Grade A, and why
field-guide-map CLAUDE.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.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cold Brew Map
Mushroom's Cold Brew Field Guide — a personal, editorial ranking of San Diego cold brew spots. Styled like a vintage Japanese tourism pamphlet crossed with an indie zine. This is NOT a tech product. It's a friend who takes coffee very seriously made you a guide.
Tech Stack
- Vite + React + TypeScript — SPA, no routing library needed
- Tailwind CSS — utility-first styling; custom design tokens via
tailwind.config.ts - shadcn/ui — used only for admin mode UI (Dialog, Slider, Form components)
- Deploy: Vercel

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.
