Claude API

Use this skill when the user is building against Anthropic APIs or SDKs, including `@anthropic-ai/sdk`, `anthropic`, or Agent SDK integrations.

What This Skill Covers

• Messages API basics across supported languages
• Streaming responses and incremental rendering
• Prompt caching for repeated context
• Tool use and agent-style orchestration
• Batches and Files API workflows
• Model selection and error handling

Working Rules

• Prefer Anthropic official docs and SDK idioms over generic LLM advice.
• Keep examples aligned with the user’s detected language when possible.
• Use the language-specific `README.md` for standard request flow, auth, and request shape.
• Use the shared docs for topics that cut across all SDKs, such as models, caching, tool-use concepts, and error codes.
• If the user asks for exact current model IDs, feature availability, or pricing, verify against Anthropic’s live docs before answering.

Reading Guide

• Basic request/response flow: `{lang}/claude-api/README.md`
• Streaming output: `{lang}/claude-api/streaming.md`
• Tool use: `shared/tool-use-concepts.md` and `{lang}/claude-api/tool-use.md`
• Prompt caching: `shared/prompt-caching.md`
• Batch processing: `{lang}/claude-api/batches.md`
• File upload flows: `{lang}/claude-api/files-api.md`
• Model choice or naming: `shared/models.md`
• API and SDK failures: `shared/error-codes.md`
• Live sources for fresh answers: `shared/live-sources.md`

Response Style

• Give production-usable examples, not pseudocode, when the user asks for implementation help.
• Call out when you are making an inference from the docs rather than repeating an explicit guarantee.
• If the user’s request depends on fast-changing details such as model names or pricing, browse Anthropic docs and cite the relevant page.
