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 | $0.05246 | $0.05246 |
| Opus 5.5 | $0.02098 | $0.02098 |
| Sonnet 5.5 | $0.01049 | $0.01049 |
| Haiku 4.5 | $0.00525 | $0.00525 |
Grade A, and why
hero 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 — 340 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Project
Mythique — a superhero/villain encyclopedia app built with Expo SDK 56 / React Native.
Targets iOS, Android, and Web. (Repo slug + internal package dir stay hero; the product is branded Mythique.)
Documentation system
docs/README.md is the docs index — start there for any feature you don't
already know. Three layers, trust flows downward:
- This file — conventions, commands, hard rules.
docs/features/+docs/architecture/— evergreen as-shipped references per domain (Explore/Pulse, Arena, dailies, search, character page, profile, sharing/OG, auth/identity, push, platform/motion, admin, pipelines, houses). Kept current: if a PR changes a domain's behaviour, update its doc in the same PR.docs/superpowers/specs|plans/— ~170 dated historical design docs. The decision record, not the current truth; status lines in them go stale. Hidden from Grep via.ignore— read by explicit path only.
Package manager
Always use yarn. Never use npm or bun.
yarn install
yarn add <package>
yarn expo install <expo-package> # use for Expo-managed packages (pins correct version)
yarn start # dev server
yarn test:ci # run all tests once (CI mode)

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.
