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 | $0.04180 | $0.04180 |
| Opus 5 | $0.02090 | $0.02090 |
| Sonnet 5 | $0.00836 | $0.00836 |
| Haiku 4.5 | $0.00418 | $0.00418 |
Grade A, and why
turbo-start-sanity 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 today.
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.

Project Overview
Turbo Start Sanity — a pnpm monorepo (Turborepo) with a Next.js 16 frontend and a Sanity Studio v6 CMS. Uses Biome/Ultracite for linting/formatting.
Commands
# Development (both apps)
pnpm dev
# Individual apps
pnpm dev:web # Next.js on localhost:3000 (Turbopack)
pnpm dev:studio # Sanity Studio on localhost:3333
# Build
pnpm build # All packages
pnpm build:web # Next.js only
pnpm build:studio # Studio only
# Lint & Format (Biome/Ultracite, NOT ESLint/Prettier)
pnpm lint # Lint all
pnpm format # Format all (auto-fix)
pnpm format:check # Check formatting without fixing
pnpm check-types # TypeScript type checking
# Per-package lint/format
cd apps/web && pnpm lint
cd apps/studio && pnpm format
# Sanity type generation (run after schema changes — both, in this order)
pnpm --filter studio extract # Refresh the committed apps/studio/schema.json
pnpm type # Generate types from schema.json (root via turbo, or apps/studio)
# Tests
pnpm test # Vitest unit tests (currently only @workspace/sanity-blocks)
pnpm test:e2e # Playwright smoke tests (apps/web, needs a running/deployed site)
pnpm --filter web test:e2e:presentation # Studio → website loop (Presentation drafts, publish, live update, no leaks); starts Studio on 3333 + `next build && next start` on 3000
Note: pnpm test at the root is turbo run test, which today only reaches
@workspace/sanity-blocks — the one package with a test script. Run a single
package's suite with pnpm --filter @workspace/sanity-blocks test.

logger/ — @workspace/logger — Structured logger class with context prefixes
typescript-config/ — Shared TS configs
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.
