Workspace Frontend for DeepSeek Harness

Rebuilds the left sidebar of DeepSeek Harness into a grouped workspace → group → session browser, and repaints every session row.

DeepSeek Harness / 工作区美化：把左侧栏重做成「工作区 → 分组 → 会话」，并让会话行显示状态、上下文与花费。

Features

Grouped sidebar

• The plugin shadows the shipped sidebar.workspaces (priority: -1) with its own browser: workspaces, then user-defined groups, then sessions. Sessions in no group stay in an Ungrouped section at the end of each workspace; sessions in no workspace at all appear in a No workspace section.
• Group actions, revealed on hover: new session, move up, move down, change colour (8-colour palette), rename (inline), delete (two-click confirm).
• A session started from a group's + lands in that group; a collapsed group is expanded first.
• Sessions drag between groups and across workspaces. Same-workspace drops rewrite the group assignment; cross-workspace drops are recorded as a display-level move (Host workspace membership is untouched).
• Manual order: ↑/↓ on a group reorders groups, ↑/↓ on a session reorders it inside its group. A group ordered by hand stops auto-sorting by time.
• Workspace actions: add workspace (native directory picker), delete workspace (two-click confirm). Deletion removes the Host registration only — sessions and files stay on disk, their rows fall into No workspace.

Session rows

• Whole-row click opens the session.
• Leading ring: blue = a question awaits you, yellow = approval / plan review pending, green = finished while unread. Colour changes play a 1 s exit plus 1 s enter sweep.
• Context ring: green → red gradient by context usage, spins while the session runs; warns once at 20 % and again at 40 %.
• Clock icon when the session has an active scheduled task.
• Per-session cost and relative last-activity time; group and workspace headers show sums.
• Row menu: open, rename, move to group…, archive / unarchive, copy session ID.

Layout

Resize handles on both sidebar boundaries (a thin line plus a rounded pull tab); drag to resize. Limits come from the Host: left 264–420 px, right up to 70 % of the viewport.

Install

Client-only plugin bundle — no dependencies, no build step.

# point the harness plugin manager at this directory
plugin_manager install_bundle  target: <absolute path to this directory>

Then refresh the page (Ctrl+R). The sidebar is rebuilt immediately and the Workspace entry appears in the sidebar icon column.

Group data is local to the browser: localStorage['dsh.session-groups.v1'] (sections, assignments, moves, orders). Nothing is written to the session log.

Compatibility

Built and verified against DeepSeek Harness 0.2.1-rc.3.

Extension points used:

• Slots: sidebar.workspaces (shadowed, priority: -1), sidebar.panellist, main, sidebar.workspaces.session.menu.item, sidebar.session.row.leading, sidebar.session.row.hover, shell.overlay
• Hooks: useWorkspaces, useSessions, useSessionStatus (pendingInteraction.kind, completionUnread), usePanelInfo
• Services: uiWorkspace (openSession, openWorkspace + beforeOpen, startSession, archiveSession, unarchiveSession, pickDirectory), workspaces.create / .delete, sessions.using / .refreshProjections, layout.selectPanel, remote.schedule.catalog
• Theme: --dsw-alias-* tokens only, each with a fallback colour. Skins that style the shipped browser by DOM class do not reach this list; token-level theming does.

Session cost is read from GET /dsh-claude-style/session-cost?id=<sessionId>, provided by the dsh-claude-style skin (cny in units of 1e-6 yuan). Without that skin the cost column shows —.

Limitations

• Session order is plugin-local; the Host's own list order is never rewritten.
• No content search in the browser, no workspace nesting, no drag reordering of groups (use ↑/↓).
• The shipped row menu and hover card are not reused; this plugin renders its own.
• No workspace may also list subagent sessions if the Host reports them in the session snapshot.
