Simon Willison: shot-scraper 1.10 — AI Agents Now Record Video Demos of Their Own Work

Main idea

AI agents can now create video demonstrations of their own work — not just static documentation. shot-scraper 1.10 introduces a video command that records Playwright sessions from a YAML storyboard. The entire feature was written by GPT-5.5 xhigh via Codex Desktop without human code intervention.

Context

Willison has long experimented with agentic coding tools and shot-scraper for web screenshots and testing. This release illustrates a new pattern: AI-written tooling that helps other AI agents document their own outputs — meta-agentic tooling.

Why it matters

For teams using agentic coding, visual documentation of agent output is a natural next step. The pattern of 'agent wrote a tool that another agent uses for documentation' signals the direction agentic workflows are evolving.
