Claude Managed Agents
Pre-built, configurable agent harness that runs in managed infrastructure.
Claude Managed Agents is Anthropic's hosted, configurable agent harness and infrastructure for running Claude as autonomous agents, aimed at long-running and asynchronous work without requiring developers to build their own agent loop, sandbox, or tool runtime.

Anthropic’s developer update adds per-agent effort settings, seeded session creation, webhooks, sub-agent event streaming, and up to 500 skills per session. The release gives teams finer controls for managed agent runs.
Anthropic released the ant CLI so Claude Platform APIs, file uploads, and Managed Agents sessions can run from the terminal, then updated Claude Code so /fork starts a background agent with the same context and prompt cache. Teams can use it to script agent runs, inspect traces, and hand work between Claude Code and the platform.
Anthropic introduced dreaming as a research preview in Claude Managed Agents alongside multiagent orchestration, rubric-based self-improvement, and webhook updates. Sub-agents now share a container and filesystem, so teams can coordinate longer-running work and manage memory across sessions.
