From da2cb2dfd999cf526062383d9359232cbd2c539d Mon Sep 17 00:00:00 2001 From: Aaryan Choudhary Date: Fri, 23 Oct 2026 00:18:05 +0530 Subject: [PATCH 1/9] feat(server): say which product checks what for accessibility The tools alone do not tell an agent that a web page and a mobile app are scanned differently, so a request like "check my app for accessibility" could reach for Website Scanner, or for nothing. The server instructions now route it: a web page to Website Scanner, a multi-step web flow to Automate with accessibility on, an app to its tests on App Automate with accessibility on, then fetchAccessibilityIssues. A test keeps every tool the line names registered.

It warns when the builds scanned different screens or ran different tests, as an issue on a screen not reached reads as resolved. "previous" is the newest earlier build of the same name, or the one just before it, as each native run is named apart. - "N more issues" is now exact on every page (it was estimated from the first row's size past page one), and a row larger than a page is still returned, so paging cannot stall on it. - An App Accessibility dashboard link is resolved by build name and number: numbers count up per build name, so a project's builds of different names share them, and the number alone could open another build. - An Espresso / XCUITest build link finds its accessibility build by the run's start, among the project's newest builds, rather than by walking the account's newest 300 App Automate builds for its name, which missed older runs. The name still tells apart runs that started together.

Issues that look alike are now paired one for one, those on the same screen and spot first, and the label tells unnamed elements apart. New and still open now add up to the later build's total, and resolved and still open to the earlier one's; the answer says so.

The "offer to write tests" directive goes with it, pending a product call. From Shreyas's review: - A comparison refuses a build with more scanned screens than are read, as the issues on the rest would count as resolved or new. - Within one test, a screen that shares half of the smaller screen's elements with a screen of the other build is the same screen, so the fixes on a mostly fixed screen are resolved rather than "not confirmed". The sheet's builds (#2 and #3 of the iOS app) compare as before. - The build before a build: a build missing from its project's list, or a project not found by name, is an error rather than "its project's first". - A dashboard link whose name matches no build resolves to the one build with its number, and refuses to guess between several. Also: fetchAccessibilityIssues points at searchCapability for the app lists, and docs/TOOLS.md lists the three App Accessibility capabilities.
