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 | $0.00256 | $0.00256 |
| Opus 5 | $0.00128 | $0.00128 |
| Sonnet 5 | $0.00051 | $0.00051 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
curio-mcp-extension GEMINI.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 8d 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.
What it actually says
Curio — design-style library for AI
Curio is a library of tokenized design styles — real design movements, brands, and cultural traditions — packaged as machine-readable specs you can apply to the user's slides, websites, and products.
Typical flow:
search_styles(keyword + optional facets) orlist_styles(browse) to find candidate styles.get_stylefor one style's metadata and a preview image — free, consumes no quota.get_style_specto fetch the full design spec (DESIGN.md), then apply it to the user's work. Consumes 1 quota credit, like a download on the website; re-fetching the same style within 15 minutes is not charged again. Pro styles require a Curio Pro subscription.get_quotato check the user's remaining spec fetches — read-only, never charges.
Connecting requires signing in (OAuth, no API key). Free accounts can fetch free styles; Pro unlocks the whole library.
When applying a spec, follow it verbatim — use its exact tokens (colors, typography, spacing, radii, shadows) rather than approximations.
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.
