Let File Browser-sourced Editor opens register existing Markdown files under the Agent Zero runtime root while preserving the stricter document artifact sandbox for ordinary document operations. Pass the file-browser source through the Editor store and cover the /a0/AGENTS.md-style path with regression tests.
Route Markdown files to Editor, txt and Office documents to Desktop, and browser-renderable files to Browser from the file browser action menu. Extend the Desktop/document allowlists for txt files, keep unsupported small files on the legacy editor path, and harden tooltip cleanup for dropdown-triggered modal closes.
Add a shared grouped action rail for Browser, Desktop, and Editor floating surface modals so modality switches, canvas docking, focus mode, New, and close controls appear in a consistent order with separators. Fix the Desktop focus button class collision that hid the canvas docking button, and align dock button labels with canvas terminology.
- rename document_artifact to office_artifact and remove retired shims/facades
- make text_editor own Markdown saves, canvas-open intent, refresh, and stale-save protection
- keep Office artifacts Desktop-only with Office formats and update skills/tests
Create the missing Editor plugin thumbnail as a 256x256 optimized JPEG matching the existing core plugin icon style.
Keep the asset below the 20 KB plugin thumbnail budget.
Remove obsolete Office markdown editor UI and handoff code now that Markdown lives in the dedicated Editor surface.
Harden the Editor modal so it opens directly into a Markdown draft and rebinds Ace to the visible root when switching surfaces.
Make Browser address Enter navigation explicit and update the canvas setup expectations for the slimmer Office shell.
Expand the dedicated Editor surface with safe rendered preview mode, ACE-backed source editing, browser-style tabs, toolbar/file actions, preview search, and richer Markdown rendering for code blocks, task lists, images, tables, math, local links, and footnotes.
Keep open Markdown files synchronized with the active context and saved tool edits, including live refresh for document_artifact and text_editor results without routing Markdown through Desktop/Office.
Add inline preview-page editing, clickable preview task-list checkboxes, source editor rehydration after preview-mode refreshes, and regression coverage for the new editor wiring and sync behavior.
Add a builtin _editor plugin that owns Markdown API/WebSocket sessions, canvas and modal UI, live refresh, tabs, prompt Extras for active-context open files, inline close confirmation, and Close All handling.
Route Markdown document artifacts to Editor while keeping Office/Desktop focused on LibreOffice formats, and update Desktop/Office prompts, menus, compatibility shims, and regression coverage.
