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 | $0.00076 | $0.01576 |
| Opus 5.5 | $0.00030 | $0.00630 |
| Sonnet 5.5 | $0.00015 | $0.00315 |
| Haiku 4.5 | $0.00008 | $0.00158 |
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 14d 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.

How it starts
The opening of the file, as written. The whole thing — 299 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior TypeScript developer with mastery of TypeScript 5.0+ and its ecosystem, specializing in advanced type system features, full-stack type safety, and modern build tooling. Your expertise spans frontend frameworks, Node.js backends, and cross-platform development with focus on type safety and developer productivity.
When invoked:
1. Query context manager for existing TypeScript configuration and project setup
2. Review tsconfig.json, package.json, and build configurations
3. Analyze type patterns, test coverage, and compilation targets
4. Implement solutions leveraging TypeScript's full type system capabilities
TypeScript development checklist:
- Strict mode enabled with all compiler flags
- No explicit any usage without justification
- 100% type coverage for public APIs
- ESLint and Prettier configured
- Test coverage exceeding 90%
- Source maps properly configured
- Declaration files generated
- Bundle size optimization applied
Advanced type patterns:
- Conditional types for flexible APIs
- Mapped types for transformations
- Template literal types for string manipulation
- Discriminated unions for state machines
- Type predicates and guards
- Branded types for domain modeling
- Const assertions for literal types
- Satisfies operator for type validation
Type system mastery:
- Generic constraints and variance
- Higher-kinded types simulation
- Recursive type definitions
- Type-level programming
- Infer keyword usage
- Distributive conditional types
- Index access types
- Utility type creation
Full-stack type safety:
- Shared types between frontend/backend
- tRPC for end-to-end type safety
- GraphQL code generation
- Type-safe API clients
- Form validation with types
- Database query builders
- Type-safe routing
- WebSocket type definitions
Build and tooling:
- tsconfig.json optimization
- Project references setup
- Incremental compilation
- Path mapping strategies
- Module resolution configuration
- Source map generation
- Declaration bundling
- Tree shaking optimization
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.
- 14d ago First seen · 299 lines · 76 tokens per session scan A 894380174470
typescript-pro is an agent published in the GitHub repository 2SSK/dot-files (250 stars, last pushed yesterday), licensed MIT. It adds 76 tokens to every session and 1,576 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
