Anthropic SDK (TypeScript)

AI-ASSISTANTS
Velocity7.5

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

docs.anthropic.com/en/api/client-sdks ↗

The TypeScript SDK tracks the platform's new surfaces while its provider packages tag empty commits.

◆Current state
The core sdk package moves quickly against the API — the latest release adds files and memory store operations, skill and user profile updates, and helpers for reading the workspace ID out of response headers, while removing a mid-conversation system content block the API no longer supports. Session-runner reliability got attention too, with tool-result sends now retried for at least the lease TTL. The Bedrock, Vertex, and Foundry packages, meanwhile, keep publishing versions whose entire changelog is an empty commit to trigger builds.
◆Where it's heading
Two release streams with very different content share one feed. The core SDK follows the platform's expansion into agent infrastructure — Managed Agents sessions and threads, deployments, and now memory stores and skills — which means the SDK's surface is a fair readout of where the API itself is going. The provider packages are release-train artifacts, republished whenever the monorepo builds, and they routinely outnumber the substantive releases in any given window. The mid-conversation system block removal is worth noting as a rare subtraction: a feature the SDK shipped earlier this year is now gone from the API.
◆Prediction
Expect the provider packages to keep shipping empty-commit tags whenever the core sdk moves, and the next real release to continue narrowing behavioral gaps between the TypeScript SDK and its siblings rather than adding surface.

◆Recent moves

  1. 15h ago

    sdk 0.118.0: files and memory store operations, workspace ID helpers

    The substantive release in this window: files and memory store additions, skill and user profile updates, and workspace ID accessors on response headers. It also removes the mid-conversation system content block the SDK added earlier this year, and makes session-runner tool-result sends retry for the lease duration — a reliability fix for long-running agent work.

    foundry-sdk 0.4.3: build-trigger commits only

    bedrock-sdk 0.32.4: build-trigger commits only

    The Bedrock provider republished from the same empty commits as its siblings. These tags fill the release window without carrying content.

    vertex-sdk 0.19.4: build-trigger commits only

    The Vertex provider's turn in the same batch — third of three identical empty-commit releases published the same day.

    sdk 0.117.1: npm re-publish and preview-build tagging

    Release-workflow plumbing: manual npm re-publishing and branch-name tagging for preview builds. Infrastructure for shipping rather than anything shipped.

    foundry-sdk 0.4.2: build-trigger commit

    A single empty commit published as a version. The fourth such tag in this six-entry window, which is the ratio worth knowing when reading this feed.
