Key point

The Claude Code 2.1.144 update simplifies the Managed Agents endpoint structure and improves behavior guidance for the CronCreate tool.

Details

Managed Agents Endpoint Changes

  • The type: "model_config" wrapper has been removed from the model_config shorthand example.
  • Now the full configuration object is composed in a simpler structure, such as {id: "claude-opus-4-6", speed: "fast"}.

Improved CronCreate Tool Description and Behavior Guidance

  • A "Not for live watching" section has been added. Since CronCreate works by re-running a prompt at set time intervals, it now clearly states that the Monitor tool should be used to check real-time logs or process output.
  • Guidelines on durability and runtime behavior have been refactored to remove duplicate code and use shared snippets.
