Signed-in founders can also have it re-run every week, with an email saying what changed. ### How is this different from running each checker? It runs 13 of our free checks together and ranks every issue by how much it would hurt a launch: P0 blocks it, P1 costs signups or rankings, P2 is polish. Each issue links to the checker that explains it and to the prompt that fixes it. ### What is the fix-all prompt? One prompt with every open issue, most important first, that you paste into Claude Code, Cursor, Codex or another coding agent. Like all our prompts it makes the agent read your code, show a plan and wait for your approval before editing. ### Does it change anything on my site? No. It only reads public pages and DNS records, the way a search engine or a visitor would. Nothing is written to your site. ### Who can see my report? Anyone with its link, which is long and unguessable; reports are never listed or indexed. Reports from signed-out runs are deleted after 90 days.
