Validation

Every specification is parsed against the schema before it is saved or rendered. A section of an unknown type, a missing required field or a page with no sections cannot get through. Limits are part of it: 12 pages, 20 sections a page, and a length for every piece of text.

Some input is corrected instead of failing the whole build:

• Text that is too long is cut at the last word boundary within its limit.
• Links are kept only if they are https://, http://, mailto:, tel:, a path or an in-page anchor. Anything else — including javascript: and data: — becomes # before it can be stored.
• In-page links written as /#section are rewritten to #section, so they work wherever the site is served.

• Audits score the result on structure, conversion, copy, SEO, accessibility and mobile, and say what to fix — see AI Agents.
• App specifications are also checked for screens nothing navigates to and navigation to screens that do not exist.
• 3D games are started in a real browser and played through before you see them.
• Sandbox builds run in a frame on an opaque origin, so even a faulty program cannot reach your account.
