## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The task thread is where people read work and guide agents. > - The mobile composer should use the same content width as the thread. > - The composer kept the desktop 80% width on mobile, so its edges did not align with the thread. > - Long assignee-aware placeholder text could also clip inside the mobile editor. > - Some extracted style tokens used legacy HSL wrappers around complete semantic colors, which made those declarations invalid. > - This pull request makes the composer full width on mobile, preserves the narrower desktop layout, wraps the placeholder, and repairs the invalid color compositions. > - The benefit is a stable mobile composer that aligns with the task thread and keeps its intended visual styles. ## Linked Issues or Issue Description Related work: Refs #11263. **What happened?** At mobile widths, the task chat composer used the same 80% width as the desktop composer. Its horizontal edges did not align with the full task thread. A long assignee-aware placeholder could clip on one line. The composer's extracted shadow also used a legacy `hsl(var(...))` wrapper around complete semantic color values, so the browser could reject the declaration. **Expected behavior** The composer must match the task thread width on mobile. It must stay narrower on larger screens. Long placeholder text must wrap inside the editor. Semantic color tokens must form valid shadows and gradients. **Steps to reproduce** 1. Open a task with the chat-style thread on a mobile viewport. 2. Compare the composer edges with the task thread edges. 3. Select an assignee whose placeholder text wraps to two lines. 4. Inspect the computed composer shadow and the extracted semantic color styles. **Paperclip version or commit** The change is based on `dc6fcd1ff1` from `master`. **Deployment mode** Local build from source. The behavior also applies to packaged web builds. ## What Changed - Made the task chat composer full width below the medium breakpoint and kept the 80% desktop width. - Matched the composer dock padding to the task thread padding. - Allowed long composer placeholders to wrap and reserved enough mobile editor height for two lines. - Replaced invalid legacy HSL wrappers around full semantic colors in extracted shadows, gradients, and approval styles. - Added a token gate that prevents legacy `hsl(var(--token))` wrappers from returning. - Added focused regression tests for responsive width, padding, placeholder wrapping, mobile height, and semantic shadow validity. ## Verification - `pnpm check:token-gates` — all four gates pass. - `pnpm --filter @paperclipai/ui exec vitest run src/components/TaskChatThread.test.tsx src/components/task-chat/TaskChatComposer.test.tsx src/components/task-chat/TaskChatComposerStyles.test.ts` — 37 tests pass. - `pnpm --filter @paperclipai/ui typecheck` — passes. - `pnpm --filter @paperclipai/ui build` — passes. The build prints existing CSS optimizer and bundle-size warnings. ## Risks - Low risk. The width change is limited to the mobile breakpoint. The desktop 80% layout remains in place. - The semantic token fixes can affect shadows and gradients that were previously invalid. The new gate prevents the invalid wrapper pattern from returning. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
