CLAUDE AGENT SDKS SHIP IN LOCKSTEP—TYPESCRIPT AND PYTHON BOTH TRACK CLI v2.1.137

By RepoJournal · Filed · About Anthropic

Both TypeScript and Python agent SDKs updated overnight to mirror the latest Claude CLI, with the TypeScript version deprecating TodoWrite tools ahead of a Task tools migration.

The TypeScript SDK jumped to v0.2.137 [1] in parity with Claude Code v2.1.137, while the Python bundled CLI also synced to 2.1.137 [3]. The previous TypeScript release, v0.2.136 [2], added `resolveSettings()` (alpha) to inspect merged settings without spawning the CLI—critical for enterprise deployments reading MDM configs—and deprecated `TodoWrite` in favor of upcoming Task tools. Python bundled the same CLI v2.1.136 [4]. Both SDKs hardened their GitHub Actions workflows by pinning to immutable commit SHAs [5], matching security improvements across financial-services and anthropic-cli. The financial-services desk documented the `allow_1p` manifest parameter [6], controlling Claude.ai sign-in visibility in enterprise configs—enterprise teams deploying Claude in Office should audit their manifest configurations. Skills.sh now tracks downloads via badge [7].
