type-safety-validator

type-safety-validator is an agent for Claude Code from aself101/agents-and-pipelines. It costs 60 tokens per session (6,377 once invoked), scanned A, original, no licence file.

A TypeScript type-safety checker that looks beyond successful compilation for unsafe type practices and gaps that can cause failures at runtime.

In plain words
What is it for?
Use it after a code validator on TypeScript projects, especially software libraries and SDKs whose consumers rely on accurate types.
Why use it?
TypeScript can compile code containing unsafe assertions or missing type information, so compilation alone may not protect library users.

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

type-safety-validator 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 8d 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.
