The problem

An assistant that can act through connected tools needs clear authorization boundaries.

The approach

  1. Build on Auth0's open-source Assistant0 template, credited to Deepu K Sasidharan.
  2. The organizer's winner announcement highlights Client-Initiated Backchannel Authentication for explicit approval of high-risk actions.

What the evidence shows

Winner of the Auth0 for AI Agents Challenge. The award is independently documented by the organizer.

Known limits

The live app requires sign-in. A precise template-versus-original contribution breakdown and a public guest account are not documented here; no claim is made that the entire application was built from scratch.
