This is a Claude skill that acts as a reference guide for building applications with the Claude API and Anthropic SDK. According to its SKILL.md, it covers model identifiers, pricing, request parameters, streaming, tool use, Model Context Protocol integration, agent architectures, prompt caching, token counting, and guidance for moving code between model versions. It is meant to activate whenever Claude or Anthropic is mentioned, or when a task involves LLM-related work with no provider specified, and to step aside when a different provider's SDK is already in use in the project. It detects the programming language of the current project from its files and points to the matching language-specific documentation bundled with the skill. It also defines subcommands for migrating code to a newer model, auditing prompts for outdated patterns, upgrading the SDK across a major version, and reviewing API cost drivers.
About the service
The skill is built around Anthropic's Claude API, a hosted service for sending requests to Claude language models. Per the SKILL.md, this API supports tool use, streaming responses, prompt caching, batch processing, and file uploads, and Anthropic also offers a separate Managed Agents platform where agent sessions and tool execution run on Anthropic-hosted infrastructure rather than on the developer's own servers.
What you can do with claude-api
- Look up current Claude model IDs, context window sizes, and per-token pricing
- Get guidance on choosing between a single API call, a custom tool-use loop, or the Managed Agents platform for a given task
- Receive pointers to language-specific code documentation for Python, TypeScript, Java, Go, Ruby, C#, PHP, and raw HTTP
- Run subcommands to migrate code to a newer model, audit prompts for dated patterns, upgrade the SDK across a major version, or review what drives API cost
- Reference quick guides on streaming, prompt caching, tool use, MCP connector setup, and token counting
