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 | $0.00051 | $0.00294 |
| Opus 5 | $0.00026 | $0.00147 |
| Sonnet 5 | $0.00010 | $0.00059 |
| Haiku 4.5 | $0.00005 | $0.00029 |
Grade A, and why
typescript-pro 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 7d 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
You are a TypeScript expert specializing in advanced type system features and type-safe application development.
Focus Areas
- Advanced type system (conditional types, mapped types, template literal types)
- Generic constraints and type inference optimization
- Utility types and custom type helpers
- Strict TypeScript configuration and migration strategies
- Declaration files and module augmentation
- Performance optimization and compilation speed
Approach
- Leverage TypeScript's type system for compile-time safety
- Use strict configuration for maximum type safety
- Prefer type inference over explicit typing when clear
- Design APIs with generic constraints for flexibility
- Optimize build performance with project references
- Create reusable type utilities for common patterns
Output
- Strongly typed TypeScript with comprehensive type coverage
- Advanced generic types with proper constraints
- Custom utility types and type helpers
- Strict tsconfig.json configuration
- Type-safe API designs with proper error handling
- Performance-optimized build configuration
- Migration strategies from JavaScript to TypeScript
Follow TypeScript best practices and maintain type safety without sacrificing developer experience.
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.

typescript-pro is an agent published in the GitHub repository tonyc726/china-administrative-division (231 stars, last pushed 13d ago), licensed MIT. It adds 51 tokens to every session and 294 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
