kubb

kubb is a skill for Claude Code from Fandhe-AI/agent-reference-skills. It costs 129 tokens per session (1,520 once invoked), scanned A, original, no licence file.

A code generator that turns an OpenAPI or Swagger description of an API into TypeScript types and client code. It can also generate validation schemas, mocks, and clients for tools such as Axios and TanStack Query.

In plain words
What is it for?
Use it to generate typed API clients, TanStack Query hooks, Zod schemas, MSW test mocks, Faker data, and related configuration from an API specification.
Why use it?
It reduces the manual work and mismatches that occur when API types and client code are written separately. Its monorepo support helps when one repository contains several related packages.

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

kubb 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 9d 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.
