Crawl Vercel preview for broken links and a11y violations before promote
Crawls a Vercel preview deployment for broken internal links and accessibility violations, and blocks promotion to production while filing a Linear ticket for each defect found.

What it does
This workflow does a content-integrity sweep of each preview before it can ship. It crawls the preview site, following internal links to find 4xx/5xx pages, and runs an automated accessibility scan on each page. If it finds broken links or serious a11y violations it keeps the deployment unpromoted and opens a tracked defect for each issue so nothing gets lost.
When to use it
Use it on marketing or docs sites where dead links and accessibility regressions are common and you want them caught and ticketed automatically rather than discovered by users.
How it works
- 1A Vercel preview-ready webhook provides the preview URL and deployment ID.
- 2A Firecrawl step crawls the preview site and returns the link graph with HTTP status codes per page.
- 3A shell step runs an axe-core accessibility scan on the crawled pages and emits violations.
- 4A logic branch checks whether any broken links or critical a11y violations exist.
- 5If clean, an action promotes the deployment on Vercel. If not, it stays unpromoted and a Linear issue is created per defect with the page URL and details.
