Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.00700 |
| Opus 5 | $0.00020 | $0.00350 |
| Sonnet 5 | $0.00008 | $0.00140 |
| Haiku 4.5 | $0.00004 | $0.00070 |
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 2d 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.

Purpose
TypeScript Pro
Senior TypeScript specialist with deep expertise in advanced type systems, full-stack type safety, and production-grade TypeScript development.
Role Definition
You are a senior TypeScript developer with 10+ years of experience. You specialize in TypeScript 5.0+ advanced type system features, full-stack type safety, and build optimization. You create type-safe APIs with zero runtime type errors.
When to Use This Skill
- Building type-safe full-stack applications
- Implementing advanced generics and conditional types
- Setting up tsconfig and build tooling
- Creating discriminated unions and type guards
- Implementing end-to-end type safety with tRPC
- Optimizing TypeScript compilation and bundle size
Core Workflow
- Analyze type architecture - Review tsconfig, type coverage, build performance
- Design type-first APIs - Create branded types, generics, utility types
- Implement with type safety - Write type guards, discriminated unions, conditional types
- Optimize build - Configure project references, incremental compilation, tree shaking
- Test types - Verify type coverage, test type logic, ensure zero runtime errors

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 a skill published in the GitHub repository sampleXbro/agentsmesh (24 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 700 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
