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 | $0.02656 | $0.02656 |
| Opus 5.5 | $0.01062 | $0.01062 |
| Sonnet 5.5 | $0.00531 | $0.00531 |
| Haiku 4.5 | $0.00266 | $0.00266 |
Grade A, and why
Narraitor CLAUDE.md scanned grade A with 1 finding 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 28d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md — Narraitor
Canonical instructions for coding agents in this repo. AGENTS.md is gitignored here, so
this tracked file is the single canon — edit it, not a copy.
Narraitor is an AI-driven narrative RPG framework. You build a world (its theme, attributes, skills, and tone), create characters in it, and play through a generated, choice-driven story with a tracked inventory and journal. Single-player web app: no backend database, player data lives in the browser (IndexedDB via Zustand persistence), and AI generation runs through the player's own provider key.
Stack
- Next.js 15 (App Router) + React 19, TypeScript strict. Node >= 20, npm.
- Zustand 5 — one store per domain under
src/state/(characterStore,inventoryStore,journalStore,worldStore, ...), persisted to IndexedDB viapersistence.ts. - Plain CSS + design tokens —
var(--token)plusclsx. No Tailwind (removed in the design-system migration); nocn(), nocva, notailwind-merge. - AI generation through
src/lib/ai/(Google Gemini via@google/genai), keyed by the player's own provider key rather than a server-held key. - Secrets in
.env.local. Never commit them.
Run it
npm run dev # scripts/dev.sh — port 3000 in the main checkout; worktrees auto-select
npm run storybook # port 6006
npm run kill # emergency: pkill -f 'next dev'
Check whether a dev server is already running before starting one (lsof -iTCP:3000).
rcv-simulator-va's main checkout also defaults to 3000 — don't run both at once.
Verify: curl -s localhost:3000 | head -1 returns HTML; Storybook responds on 6006.
The quality gate
Run before any commit — CI runs these separately and the production build enforces lint and types anyway:
npm test # Jest unit/integration
npm run type-check # tsc --noEmit
npm run lint # ESLint (Next + test/script globs, JSX/markup hygiene)
npm run lint:css # Stylelint over **/*.css — run after ANY .css edit
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.
