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 | $0.00287 | $0.00287 |
| Opus 5.5 | $0.00115 | $0.00115 |
| Sonnet 5.5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
skills javascript-formatting.instructions.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 1mo 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
JavaScript/TypeScript Code Formatting Instructions
Follow these rules when working on skills that contain JavaScript or TypeScript code examples.
Code Formatting
- ALWAYS format JavaScript and TypeScript code examples with Prettier before every commit
- Run
npm run formatfrom the repository root to format all code
Formatting Before Commits
Before committing changes to any JavaScript/TypeScript code examples in markdown files:
- Run
npm run formatto automatically format all files - Review the formatted output to ensure code examples remain readable
- Commit the formatted changes
Alternatively, use npm run format:check to verify formatting without making changes.
Code Blocks in Markdown
When editing JavaScript/TypeScript code blocks in markdown files:
- Prettier will automatically format code blocks with language identifiers:
javascript,typescript,js,ts,jsx,tsx - Ensure code blocks are properly marked with the correct language identifier
- Preserve the readability of code examples after formatting
Skills Covered
This formatting requirement applies to the following skills:
apollo-client- React applications with Apollo Clientapollo-server- GraphQL servers with Apollo Servergraphql-operations- GraphQL operations and queries
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.
