zhifengjiang/dsh-hover-archive

Codex-style hover archive for DeepSeek Harness Web.

Hover a sidebar conversation row and an Archive icon appears at the far right; one click archives the session. No menus, no dialogs.

简体中文

Features

• Hover → Archive icon at the far right of the session row, exactly like the Codex conversation list.
• One click archives through the official workspaces.archiveSession API — the same face the built-in "…" menu uses, so archived sessions land in the same place and obey the same rules.
• Blank rows untouched: the "New Session" placeholder row never gets a button.
• zh / en labels follow the app locale and re-label live on locale switch.
• Keyboard accessible: the button is a real <button>; it reveals on :focus-within and fires on Enter/Space.
• Busy / error states: the icon dims while archiving and flashes the error color with the failure message as a tooltip if the call fails.
• Zero dependencies, zero build step: plain JavaScript, installs from source without any allowBuilds approval.
• Self-tests: npm test runs syntax checks plus a dependency-free DOM smoke test.

Install

dsh plugin --profile web add github:zhifengjiang/dsh-hover-archive

Then restart dsh web (or your desktop client) and refresh the page.

Uninstall:

dsh plugin --profile web remove dsh-hover-archive

How it works

• A pure client plugin (dsh.client, platform web) that injects a button into every actionable sidebar session row — the elements carrying data-session-id.
• The button is appended as the row's last child, so it renders to the right of the stock "…" row menu and is revealed purely by CSS on :hover (and :focus-within).
• A MutationObserver re-decorates rows across React re-renders; decoration is idempotent (one button per row, blank rows skipped).
• The click is intercepted in the capture phase (stopPropagation + preventDefault), so archiving never opens the session.
• Archiving calls ctx.workspaces.archiveSession(id); the stock projection then removes the row from the list, and archiving the current session falls back to the same sweep the built-in action uses.

Why a button instead of a menu item

The stock row already archives in two clicks (hover → "…" → Archive). This plugin restores the Codex-style one-hover-one-click affordance. DeepSeek Harness 0.1.0-rc.6 exposes no public slot for extra session-row actions, so the button is injected into the row DOM — the same workaround community plugins such as dsh-session-manager and dsh-plugin-session-delete rely on.

Compatibility

• Built against DeepSeek Harness 0.1.0-rc.6 (the @deepseek-ai/dsh-client-runtime workspaces face).
• Platform: DSH Web. Any shell that renders the upstream web sidebar shows the button; a shell that replaces the sidebar with a native list may not.
• Older harness builds without workspaces.archiveSession are detected at runtime — the plugin logs a warning and disables itself instead of breaking the UI.
• Coexists with dsh-session-manager, dsh-plugin-session-delete and the built-in "…" menu: this plugin adds one more affordance on the same row and calls the same official API.
