Multi-level agent hierarchies and composition Agents can now spawn nested sub-agents up to five levels deep, use configured agents as subagent tools, and coordinate through parent-child relationships with visual tree displays. Seen in: Claude Code, Cline, Kimi Code, Deep Agents Code, Devin
Role-based model routing for sub-agents Sub-agents can use different models, providers, and reasoning settings based on their assigned role or task complexity, optimizing performance across specialized workflows. Seen in: CodeWhale, Kilo Code, Warp
Asynchronous task queuing and background execution Developers can queue multiple prompts while agents work, move long-running tasks to background, and switch between local and cloud execution mid-run without interruption. Seen in: Amp, Cline, Kimi Code, Warp
Expanded MCP server ecosystem with marketplace distribution MCP servers now support OAuth authentication, can be configured once and distributed team-wide through marketplaces, and include 48+ new engineering connectors for integrations like Miro, Postman, and Calendly. Seen in: Cursor, Devin, Claude Code, Cline
Remote and cloud-native development workflows Tools now support cloud environment setup, remote agent execution on isolated machines, mobile control of desktop agents, and automatic local-to-cloud handoff when devices sleep. Seen in: Amp, Cursor, OpenAI Codex, Warp
