From c84d7f4cb815839f6100e9d2fc7bc4889461e98d Mon Sep 17 00:00:00 2001 From: Molecule AI Core-UIUX Date: Sat, 16 May 2026 10:25:29 +0000 Subject: [PATCH 01/17] fix(canvas/ChatTab): add WCAG 2.4.7 focus-visible ring to the talk_to_user Enable button PR #1256 has an outstanding WCAG blocker: the "Enable" button that re-enables agent-to-user messaging lacks a focus-visible ring, making keyboard navigation invisible for sighted keyboard users. Adds focus-visible:ring-2 (with matching accent colour and zinc-900 offset) to the Enable button className, satisfying WCAG 2.4.7 (Focus Visible). Also adds ChatTab.talkToUserBanner.test.tsx with 5 test cases: - Banner hidden when talkToUserEnabled=true - Banner shown when talkToUserEnabled=false - Enable button renders - Enable button calls PATCH /workspaces/:id/abilities with correct payload - Enable button has focus-visible:ring-2 class (WCAG 2.4.7) Co-Authored-By: Claude Opus 4.7 --- canvas/src/components/tabs/ChatTab.tsx | 2 +- .../ChatTab.talkToUserBanner.test.tsx | 132 ++++++++++++++++++ 2 files changed, 133 insertions(+), 1 deletion(-) create mode 100644 canvas/src/components/tabs/__tests__/ChatTab.talkToUserBanner.test.tsx diff --git a/canvas/src/components/tabs/ChatTab.tsx b/canvas/src/components/tabs/ChatTab.tsx index d6a9b85ca..6792ee147 100644 --- a/canvas/src/components/tabs/ChatTab.tsx +++ b/canvas/src/components/tabs/ChatTab.tsx @@ -383,7 +383,7 @@ function MyChatPanel({ workspaceId, data }: Props) { // ignore — user will see no change and can retry } }} - className="px-2 py-0.5 text-[10px] font-medium bg-accent/10 hover:bg-accent/20 text-accent rounded border border-accent/30 transition-colors shrink-0" + className="px-2 py-0.5 text-[10px] font-medium bg-accent/10 hover:bg-accent/20 text-accent rounded border border-accent/30 transition-colors shrink-0 focus:outline-none focus-visible:ring-2 focus-visible:ring-accent focus-visible:ring-offset-1 focus-visible:ring-offset-zinc-900" > Enable diff --git a/canvas/src/components/tabs/__tests__/ChatTab.talkToUserBanner.test.tsx b/canvas/src/components/tabs/__tests__/ChatTab.talkToUserBanner.test.tsx new file mode 100644 index 000000000..fceea0389 --- /dev/null +++ b/canvas/src/components/tabs/__tests__/ChatTab.talkToUserBanner.test.tsx @@ -0,0 +1,132 @@ +// @vitest-environment jsdom +// +// Tests for the talk_to_user disabled banner in ChatTab. +// +// When a workspace has talk_to_user_enabled=false, the agent cannot send +// canvas messages to the user.
