What it does

Runs a nightly audit of every product screenshot in your documentation. For each doc image, it loads the matching live product screen, captures a fresh screenshot, and compares the two pixel regions. When the difference exceeds your threshold, the screenshot is marked stale and bundled into a single Linear issue for the docs team.

When to use it

Use it when your product UI ships faster than your docs and readers keep seeing outdated screenshots. A nightly cadence catches drift within a day instead of at the next manual docs review.

How it works

  1. 1A nightly schedule kicks off the sweep.
  2. 2The flow reads the docs repo from GitHub and extracts every screenshot reference plus the product URL each one documents.
  3. 3Browserbase loads each live screen and captures a current screenshot.
  4. 4A visual-diff step compares each fresh capture to the published image and scores the pixel delta.
  5. 5A logic branch keeps only screenshots whose delta crosses the staleness threshold.
  6. 6A single Linear issue is created listing every stale screenshot with file path, screen URL, and diff score.
