New Features

  • terminal_reason on ResultMessage: ResultMessage.terminal_reason now surfaces why the query loop ended ("completed", "max_turns", "aborted_streaming", "aborted_tools", etc.). A value of "aborted_streaming" or "aborted_tools" means the turn was cancelled via ClaudeSDKClient.interrupt(). Mirrors the TypeScript SDK's SDKResultMessage.terminal_reason (#1142)
  • Typed model_usage on ResultMessage: ResultMessage.model_usage is now typed as dict[str, ModelUsage] instead of dict[str, Any], with a new ModelUsage TypedDict that mirrors the TypeScript SDK's shape. Includes optional canonicalModel and provider fields for stable model identification across provider-specific aliases (#1143)

Internal/Other Changes

  • Updated bundled Claude CLI to version 2.1.218
