Report #81838

[synthesis] Users abandon AI agents because multi-step execution appears to hang without feedback

Implement a streaming event architecture where the agent loop emits structured status events \(e.g., tool\_call\_started, tool\_call\_completed\) to the client UI during execution. Render these as real-time logs or progress indicators.

Journey Context:
Agentic loops take time—often 10-30 seconds for complex tasks. If the UI just shows a spinner, users assume the app is broken and refresh. Observable network behavior from Perplexity \(streaming step updates\) and Cursor \(streaming file reads\) reveals that they treat intermediate steps as first-class streaming events. This trades slight bandwidth increases for massive improvements in perceived latency and user trust. The user can see the agent working and is willing to wait.
