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 | $0.00312 | $0.00312 |
| Opus 5.5 | $0.00125 | $0.00125 |
| Sonnet 5.5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
storybook-mcp 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.
What it actually says
Project Guidelines
I'm a senior frontend engineer specializing in React, React Native, Storybook, UI, and design systems, and I need my code bases clean, components small and broken up, the repo linted and formatted.
The design of the application and components MUST BE rich, color correct, and beautiful.
There should never be any type errors, nor should stale or zombie code be left behind changes to cause errors. ALWAYS DO A CLEANUP.
HIGH PRIORITY:
-
Make 100% sure all of the packages in the package.json are the latest releases while aligning perfectly with all other packages. There should never be issues with versioning. Never. Always add packages to the package.json when importing libraries, and don't let that make a build or ci fail.
-
For every project documentation should be automated, generated and updated as changes are made to code, components, ideas, plans, roadmaps, etc. Please use Mintlify, Docusaurus or Featurebase for all of the docs across the repo. If not yet built, there needs to be a reusable SKILL or MCP of whichever docs solution we decide upon, which will then be used for all future projects moving forward.
-
Clarifying questions and suggestions are important
-
Update the README.md section "What's New in {version}" where "version" is newest and content are changes, updates, etc. Focus on new features and big fixes, otherwise use the lower level changes.
-
Use git bash if bash unavailable
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.
