A self-improving agent team for checking important browser workflows before every release.

Project description

Launch Loom coordinates focused agents, scores the quality of each completed run, and uses reviewer feedback to improve the next attempt. The team built the full workflow during the hackathon, using Replay.io for the core agent loop and Pioneer for evaluation, communication, or runtime support. The demo includes a visible activity trace so judges can inspect what each agent did and where human approval was required.

Technical architecture

Browser-use agents execute saved customer journeys while a second agent compares screenshots and traces against the last known-good run.

Setup instructions

Clone the public repository, install dependencies, copy .env.example to .env.local, add the documented API keys, and run the development command in the README.

Lessons learned

The team found that clear handoffs and fast evaluation loops mattered more than adding more agents. Replay.io handled orchestration while Pioneer made the result easier to inspect and improve.
