Summary

A developer tool that records AI agent runs inside a sandboxed GitHub repository, capturing terminal/browser sessions and turning them into replayable narrated videos for improved observability.

I’ve been experimenting with agent observability. The project lets an agent try a GitHub repo inside a sandbox, records the terminal/browser session, and turns the run into a replayable narrated video. The motivation: agent text summaries are often too compressed. For real agent work, I want to see what happened — what opened, what failed, what recovered, and what the final state looked like. Flow: repo → sandbox → agent run → recording → replayable video
