Anthropic launched multiagent orchestration, outcomes and webhooks in public beta and dreaming newest feature in research preview

Multi-agent orchestration enables task delegation to specialized sub-agents.

Each sub-agent has its own context window, but they share a container + filesystem to coordinate work.

Agents can self-improve using a rubric that describes task completion.

A dedicated grader sub-agent uses the rubric to evaluate any work done and returns feedback for the next iteration.

Agents can post updates to webhooks configured in your Claude workspace.

This removes the need to keep an SSE stream open or poll for completion.

Agents write to memory in a session. Dreaming is a background process that reflects over many sessions to curate memories: it can edit them based on patterns, add new skills, or remove stale ones.

To get started with any of these features, try /claude-api skill in Claude Code or the OSS repo
