Official Anthropic SDK patterns for TypeScript/Node.js — client setup, Messages API, streaming, tool use, vision, extended thinking, structured outputs, prompt caching, batch API, and production best practices.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Anthropic SDK Patterns

> **Quick Guide:** Use the official `@anthropic-ai/sdk` package to interact with Claude models directly. Use `client.messages.create()` for single-turn and multi-turn conversations. Use `client.messages.stream()` for streaming with event-based consumption. `max_tokens` is always required. Content blocks are typed unions (`text`, `tool_use`, `thinking`). Use `client.messages.parse()` with `zodOutputFormat()` for structured outputs. Tool use requires a tool-result loop -- Claude returns `tool_use` blocks, you execute the tool and send back `tool_result` blocks. Extended thinking adds `thinking` content blocks before the response.

## CRITICAL: Before Using This Skill

**(You MUST always provide `max_tokens` in every `messages.create()` / `messages.stream()` call -- it is required and has no default)**

**(You MUST handle the `stop_reason` field to detect `end_turn`, `max_tokens`, `tool_use`, and `stop_sequence` -- ignoring it causes silent truncation or broken tool loops)**

How to install

The exact contents, by fingerprint
mdr add agents-inc/skills/ai-provider-anthropic-sdk@sha256:4220949b1da0b3cf

The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
