typescript-expert is an agent for Claude Code from obre10off/awesome-claude-code-agents. It costs 52 tokens per session (5,513 once invoked), scanned A, original, no licence file.

An agent focused on TypeScript, a programming language that adds type checking to JavaScript. It covers advanced types, generics, decorators, strict type safety, and larger application design.

Writing and reviewing TypeScript, improving type inference, working with complex types and decorators, and making architectural decisions.
Why use it?
It helps with TypeScript code where types are difficult to understand, infer, or keep consistently safe across an application.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

typescript-expert scanned grade A with 1 finding 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 4d 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.

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.
