Make file creation opt-in through document_artifact, move document file cards to final responses, and keep the tool payload as a quiet execution record.
Deduplicate response cards by file identity, refresh open Desktop canvas sessions after saved edits, and harden document_artifact edit input normalization for common append/update shapes.
Update prompts, skills, styles, and regression coverage for response-only file actions and explicit-only canvas opening.
Keep Office document artifacts from auto-opening the canvas while adding plugin-owned Download and Open in canvas message actions. Add format-specific skills for Markdown, Word, Excel, and presentation workflows, and clarify the startup-warmed Desktop runtime remains visually opt-in.\n\nCover the Excel method=create path, Markdown-first/no-auto-open policies, response affordance copy, document action buttons, and Desktop bootstrap with focused regressions.
Rework the Office canvas into the Desktop surface, with Markdown editing for text documents and official LibreOffice/Xpra sessions for DOCX, XLSX, and PPTX. The panel now presents Desktop-oriented actions, named header buttons, persistent session tabs, adaptive modal/canvas sizing, and fast client-side Xpra frame fitting during resize.
Stop auto-opening the canvas from document tool results, hide the canvas on mobile-width layouts, and emit resize lifecycle events so embedded desktop surfaces can pause expensive work while the user drags.
Add read/edit support for Office document artifacts, including direct DOCX, XLSX, and PPTX updates with version history preservation. Inject compact active canvas metadata so agents can discover opened files without loading file contents. Move detailed usage guidance into the office-artifacts skill and keep the always-on tool prompt lean to avoid context bloat.
- Auto-open Office and Browser canvas surfaces from fresh tool results, including history/result messages.
- Preserve Browser target IDs when focusing a canvas session from tool output.
- Convert substantial response-style artifacts into Office documents at runtime, without relying only on prompt compliance.
- Attach Office artifact metadata to the completed response log so the canvas opens without leaving a dangling Processing group.
- Polish Office UX by removing the inactive version-history action, showing only the healthy dot, and improving Collabora blank-load recovery with browser state cleanup.
- Deduplicate auto-open events and ignore stale results.
