Organization API lands SDK-wide, Claude Code patches production paths
This week Anthropic shipped the Organization API across every official SDK, patched two Claude Code production failure modes, and restructured formal-math work toward a multi-project Lean setup.
The week's centerpiece is the Organization API landing across all three flagship SDKs: python, Ruby, and C# [1][2][3]. Support is now uniform, so teams moving org-level workloads between SDKs no longer need custom wrappers. The C# SDK also shipped Bedrock v0.13.0 in the same release [4]. For Java users, a Bedrock fix stops the SDK from clobbering the request body's anthropic_beta with header betas [5], correcting a case where beta headers silently overwrote body-level configuration.
Claude Code and its surrounding tooling spent the week tightening reliability. Linux users get v2.1.245, which fixes a startup crash [6]; v2.1.246 followed later in the week [7]. In claude-code-action, download_job_log is now bounded against a stalled log fetch [8][9], preventing a job from hanging indefinitely when the log endpoint stalls. Branch handling also hardened: valid branch names may now include parentheses [10], and branch names are URL-encoded in GitHub links [11]. Bundled CLI versions moved to 2.1.245 across the Python agent SDK [12] and the base action sync [13].
The TypeScript agent SDK reached v0.3.245 [14], claude-code-action v1.0.205 [15], and anthropic-cli v1.27.0 [16]. We covered the security wildcard warning patch and the stalled log fetch fix at the daily level [7]. Note the SDK version numbering now tracks the CLI release cadence, so a patch release is a patch release across the stack.
Formal-math work restructured toward multi-project Lean. The cookbook dropped unverified cost claims, and formal-math tightened its authorship and CI processes [6]. Meanwhile, Buffa wired shared descriptor pools to cut codegen token blow-up [6]. These are internal process shifts, but they signal how Claude Code's prompt and codegen paths are being consolidated for correctness and efficiency.
Two smaller plugin-marketplace additions round out the week: Noibu joined the Anthropic plugin marketplace [17][18]. If you rely on SDK parity, the Organization API support is the actionable win: upgrade your python, ruby, or C# SDK before your next org-level integration.
