Claude API Builder

Use this skill when the task is specifically about Anthropic or Claude API integration.

Trigger Signals

• Imports like anthropic, @anthropic-ai/sdk, or Agent SDK packages
• Requests about streaming, tool use, prompt caching, file uploads, or Claude batch jobs
• Questions about choosing Anthropic API patterns for an app

Workflow

1. Detect the project language and SDK surface.
2. Choose the smallest fitting pattern: simple messages, streaming, tools, batches, or files.
3. Prefer official docs and SDK-native examples.
4. Keep model names, error handling, and retries explicit.
5. Explain when to browse live docs for fast-moving API details.

Guardrails

• Do not pivot to non-Anthropic SDKs unless the user asks.
• Prefer primary documentation over memory for model/API specifics.
• Separate one-shot prompts from stateful agent workflows.

Example Requests

• Add Anthropic streaming support to this TypeScript app.
• Help me implement tool use with the Python Anthropic SDK.

Inputs

• Project language
• Anthropic API feature needed
• Performance or UX constraints

Outputs

• Recommended API pattern
• Implementation guidance
• SDK-specific caveats

Success Criteria

• The guidance matches Anthropic APIs specifically.
• The selected pattern fits the use case and language.
• Fast-moving API details are called out clearly.

Non-Goals

• General LLM vendor-neutral advice
• Non-Anthropic SDK design by default
