shot-scraper adds video demo feature for agents

shot-scraper 1.10, released by Simon Willison, introduces a new command called shot-scraper video. This feature works based on Playwright and captures a sequence of actions performed on a web application as an MP4 video, following a user-defined YAML storyboard file.

The key features are as follows:

• Agent verification tool: You can leave a visual demo of how code written by an AI coding agent actually works on the web, which is useful for increasing confidence in the results.
• Storyboard-based automation: Complex workflows can be reproduced by defining scenarios such as clicks, input, waits, and JavaScript execution in a storyboard.yml file.
• AI utilization: The post shows a case of using GPT-5.5 to generate a YAML storyboard for manipulating a complex web interface (Datasette), suggesting that agents can even write demo scenarios themselves.
