The Claude API skill is one of the example skills in Anthropic's skills repository. Its description calls it a reference for the Claude API and Anthropic SDK, covering model IDs, pricing, parameters, streaming, tool use, MCP, agents, caching, token counting and model migration. It is set to trigger when a prompt mentions Claude or Anthropic, when a user asks about LLM pricing or limits, or when the task looks like building with an LLM and no provider is named, and it skips projects that use another provider. The folder holds language directories for Python, TypeScript, Go, Java, C#, PHP, Ruby and curl. The folder LICENSE.txt is Apache 2.0, and the draft lists /plugin marketplace add anthropics/skills for install. The repository was last pushed on 28 October 2026. It suits developers building on the Claude API. A limit is that it concerns Anthropic products only. We have not run it ourselves for this note.
