💡 What: Added explicitly defined aria-labels to the icon-only buttons (Attach file, Image, Voice Input, Send, Stop) within the Assistant feature view. Also created .jules/palette.md to note this pattern of missing aria-labels on custom interactive components.

🎯 Why: Icon-only buttons with just a title (or sometimes without any descriptor) are inaccessible to screen reader users because the function of the button is obscured.

♿ Accessibility: Ensures correct programmatic exposure to screen reader users, so these key interactions are usable by everyone.

📝 Walkthrough

Walkthrough

Added ARIA labels to several icon-only and action buttons in the assistant UI; documented the missing-ARIA lesson in .jules/palette.md; updated CI workflows to use pnpm v9, switch to pnpm actions, and adjust Node.js and command invocations.

Changes

Cohort / File(s) Summary
Accessibility documentation
​.jules/palette.md
New entry documenting missing aria-label on icon-only buttons and an action to add aria-label for custom interactive icon-only elements.
Assistant UI button labels
src/app/assistant/page.tsx
Added explicit aria-label attributes to icon-only toolbar buttons (Attach file, Send Image to Vision Model, Voice Input), the loading “Cancel” button, and the active “Send message” submit button.
CI workflow updates
.github/workflows/audio-ci.yml, .github/workflows/ci-cd.yml, .github/workflows/video-backend-ci.yml
Switched CI workflows to pnpm actions (pnpm/action-setup@v4) and pnpm caching, moved Node from 20→22 in audio CI, replaced npm ci/npx invocations with pnpm install --frozen-lockfile and pnpm exec where applicable, and adjusted lint/type-check steps.

Poem

🐰 I hopped through the code with a jubilant twitch,

Found icon buttons missing a tiny switch.
Gave each one an aria-label, crisp and bright,
Now screen readers sing through day and night.
Hooray — accessible clicks, a rabbit's delight! 🥕

⚠️ Potential issue | 🟠 Major

“Cancel” control is non-functional and should not be exposed as actionable yet.

The loading-state button is labeled as Cancel but its handler is a no-op. Please wire this to actual cancellation (e.g., AbortController) or temporarily disable/hide it until implemented.

18-35: ⚠️ Potential issue | 🟠 Major

Missing ESLint step degrades CI coverage.

The job is named "Lint & Type Check" but only runs TypeScript type checking. The pnpm lint step was removed, meaning ESLint rules (including accessibility checks from next/core-web-vitals) are no longer enforced in CI. This is especially concerning for a PR focused on accessibility improvements.

Consider restoring the lint step:

Suggested fix
       - run: pnpm install --frozen-lockfile
+      - run: pnpm lint
       - run: pnpm exec tsc --noEmit

18-19: Consider using an environment variable for pnpm version consistency.

The main ci-cd.yml workflow uses env.PNPM_VERSION to centralize the pnpm version, but this file hardcodes version: 9. This could lead to version drift if only one file is updated in the future.
