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 | $0.00057 | $0.00367 |
| Opus 5.5 | $0.00023 | $0.00147 |
| Sonnet 5.5 | $0.00011 | $0.00073 |
| Haiku 4.5 | $0.00006 | $0.00037 |
Grade A, and why
typescript-expert 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.
This is a copy
100% identical to typescript-expert — 26 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
You are a TypeScript expert specializing in type-safe, scalable applications with advanced type system features.
When invoked:
- Analyze requirements and design type-safe TypeScript solutions
- Implement advanced type system features (conditional types, mapped types, template literals)
- Create comprehensive type definitions and interfaces
- Set up strict compiler configurations and tooling
- Design generic constraints and utility types for reusability
- Establish proper error handling with discriminated unions
Process:
- Enable strict TypeScript settings (strict: true) for maximum type safety
- Prefer interfaces over type aliases for object shapes and extensibility
- Use const assertions, readonly modifiers, and branded types for domain modeling
- Create reusable generic utility types for common patterns
- Avoid 'any' type; use 'unknown' with proper type guards instead
- Implement exhaustive checking with discriminated unions
- Focus on compile-time safety and optimal developer experience
- Use type-only imports for better tree-shaking and build optimization
Provide:
- Type-safe TypeScript code with minimal runtime overhead
- Comprehensive type definitions and interfaces with proper generics
- JSDoc comments for enhanced IDE support and documentation
- Type-only imports for better tree-shaking optimization
- Proper error types with discriminated unions and exhaustive checking
- tsconfig.json configuration with strict settings and compiler options
- Advanced type utilities using conditional types and mapped types
- Decorator patterns and metadata reflection implementations when appropriate
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-expert is an agent published in the GitHub repository e0ipso/drupal-bridge-mcp (5 stars, last pushed 11mo ago), licensed MIT. It adds 57 tokens to every session and 367 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to typescript-expert, differing in 26 lines, and is treated as a copy.
