Spotter Round is a kit of skills and runnable scripts that make a coding agent prove its work instead of describing it. Install it into Claude Code, Codex, Cursor or Gemini CLI and the agent runs the same checks every time, with a pass or fail you can read and a deliberately broken example each check has to catch first.
What it checks: the app still builds at real screen sizes, in both themes, with a clean console; no text is cut off or stranded; before-and-after pictures across three browsers, so the design did not move; speed comparisons made fairly; and, once it ships, a live site that serves your new build, not an old copy.
What you get: the download (skills, scripts, docs and the broken examples), numbered updates with a list of what changed, and a license for one company on as many machines and projects as you like. Every future version of Spotter Round is included at no charge, so you never pay for a new version. Fourteen-day refund, no questions. No tracking, no license check, nothing phoning home: the scripts only visit addresses you type, and the npm registry when the speed comparison fetches Lighthouse into a project that doesn’t have it.
The email, agent-setup, WordPress and web-app skills now have packs of their own, and the All-Access Bundle has every pack, now and later.
