March 20, 2026 - By Praveen Nair

Similarities

Aspect
Core idea	Delegate multi-step tasks to AI — it plans, executes, checks in, and delivers
AI engine	Both use Claude as the underlying model and share the same “agentic harness” — the system that allows the AI to use tools and the guardrails around how it functions
Human-in-loop	Both show you a plan before acting, require approvals for significant actions, and let you redirect mid-task
Background execution	Tasks run asynchronously — you can step away and come back to completed work
MCP standard	Both use the Model Context Protocol for connecting to external tools
Status	Both currently in Research Preview as of March 2026
