Warnings (6 rules)

warning Unfilled template or prompt-leak text

Rule ai.prompt_leak · AI Content · 1 occurrence(s)

  • https://devbj.com/posts/astro-github-actions-cache-build/ — The page contains unfilled template or prompt-echo text — e.g. "[[ github.sha ]]". This usually means a generation template was published without being completed or cleaned up. Fill in or remove the placeholder so readers and crawlers don't see the scaffolding.

warning Thin content (low word count)

Rule content.thin · Content · 4 occurrence(s)

warning Homepage duplicated across protocol/host variants (no redirect)

Rule duplicate.protocol_host · Duplicate · 1 occurrence(s)

  • https://devbj.com/ — http://devbj.com/ serves the same homepage content with a 200 and no redirect — Google sees a duplicate. Pick one canonical host/scheme and 301-redirect the others.

warning Duplicate <title> across pages

Rule duplicate.title · Duplicate · 11 occurrence(s)

warning Internal link points to a redirect

Rule links.redirect_target · Links · 101 occurrence(s)
