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 | $0.00052 | $0.00283 |
| Opus 5.5 | $0.00021 | $0.00113 |
| Sonnet 5.5 | $0.00010 | $0.00057 |
| Haiku 4.5 | $0.00005 | $0.00028 |
Grade A, and why
typescript-code-writer 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 9d 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
Write clean, type-safe TypeScript following project standards.
Before Writing
Read the files you will change before making edits. For single-file edits, reading the target file is sufficient. For cross-cutting changes, read the directly affected modules. Check tsconfig.json and package.json for TypeScript version, module system, strictness settings, and dependencies.
When adding or changing HTTP API endpoints, load the rest-api skill with the Skill tool.
Quality
Write code that passes the project's type checker, linter, and formatter. After editing, discover them from project config (tsconfig.json, ESLint, Biome, Prettier) and run tsc --noEmit on the affected project plus the configured linter and formatter, unless a project hook already does it.
Report
End with a short report: files changed, checks run with their results, checks skipped and why, and assumptions made.
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.
