Description of the web.run operations and the switch to JSON with GPT-5.3, plus the "Bigfoot effect" of falling domain diversity and the distinction between parametric and dynamic visibility.
The article was accurate when published and, three months later, is outdated in the format details. It is the object lesson written into CLAUDE.md: an external finding needs its date, otherwise you read an old state as a contradiction.
| Claim | Status | Evidence |
|---|---|---|
| web.run with twelve operations (search_query, open, find, click, screenshot, product_query, widgets) | outdated | For us line types business, fast, slow, search, product, image, open, length. click/find/screen only named via introspection. |
| Since 5.3 structured JSON objects instead of text commands | outdated | Since 16-20 Aug 2026 pipe syntax again (Mohanadasan); for us only pipes. |
| browse_rewritten_queries for product requests, Google marker strlid | outdated | Not present; instead product|... lines with model names. |
| Cited domains per answer fell from 19.1 to 15.2 | unverifiable | 9-22 domains per searching question for us; no comparison value before 5.3. |
