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 | $0.02013 | $0.02013 |
| Opus 5.5 | $0.00805 | $0.00805 |
| Sonnet 5.5 | $0.00403 | $0.00403 |
| Haiku 4.5 | $0.00201 | $0.00201 |
Grade A, and why
demokit 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DemoKit OSS
For Claude: This is the open-source DemoKit SDK - a framework for turning real SaaS apps into interactive product demos by intercepting API calls and returning mock data.
UI work: two rule sets, and they are opposites. apps/dashboard/ is a normal token-locked Next app. packages/react/ renders inside other people's apps and follows guest rules. See § Design skills below before touching either.

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.
