You can now set an effort level on a Claude Managed Agents agent's model configuration. Pass effort inside the model object when you create the agent.
Anthropic has shipped several updates to Claude Managed Agents on the Anthropic platform, covering agent configuration, webhooks and session creation, detailed in the July 22 release notes.
- Agents can now have an effort level set on their model configuration, passed inside the model object when the agent is created.
- Webhooks now cover the environment and memory store lifecycle, with four environment event types and three memory store event types, so developers can react to those changes without polling.
- New sessions can be seeded with up to 50 initial events (user messages or defined outcomes) at creation, which starts the agent loop in the same call instead of requiring a separate request.
- The version field used when updating an agent is now optional: include it for optimistic concurrency checks, where a mismatch returns a 409 error, or omit it to apply the update unconditionally.
- Session thread event streams now support event deltas.
