Anthropic SDK (TypeScript)

AI-ASSISTANTS
Velocity5.1

Official TypeScript/JavaScript SDK for the Anthropic API; also includes vertex and bedrock variants.

Anthropic ships a dedicated AWS client for Claude Platform on AWS, alongside steady Managed Agents expansion.

◆Current state
The TypeScript SDK family is on a weekly bump cadence (0.94 → 0.97 in two weeks) with two structural moves underneath. First, a new [email protected] introduces an AWS client for Claude Platform on AWS — a distinct package from the existing bedrock-sdk. Second, Managed Agents (CMA) is broadening visibly: webhooks, multiagents and outcomes types, vault validation, self-hosted sandboxes with helpers, a BetaManagedAgentsSearchResultBlock, and cache diagnostics beta in successive releases.
◆Where it's heading
Anthropic is splitting its AWS distribution into two channels — Bedrock for the model API, and a separate Claude Platform on AWS surface that the new aws-sdk implies will bundle Managed Agents and related platform features. Managed Agents itself is hardening from a single-agent harness into a multi-agent orchestration product with webhooks, outcomes, and self-hosted execution. The combination reads as Anthropic moving from model API to deployable agent platform.
◆Prediction
Expect a public Claude Platform on AWS announcement (likely an AWS Marketplace listing or product page) once [email protected] stabilizes. Managed Agents will keep adding orchestration surface — likely persistent memory hooks, audit endpoints, or agent-to-agent messaging primitives.

    aws-sdk 0.3.0: AWS client for Claude Platform on AWS

    ⚡ SPARK

    aws-sdk 0.3.0 adds an AWS client for Claude Platform on AWS — a separate package from the long-standing bedrock-sdk. The naming and packaging imply a new direct distribution channel in AWS distinct from Bedrock's per-model API.
