dsh-sidebar-files

A sidebar file tree for DeepSeek Harness. Adds a Sessions / Files tab strip to the left sidebar and an inline, lazy-loaded file tree over the active workspace — with per-extension brand icons, copy-path, and send-to-agent actions.

Plugin status. Built and verified against the published harness (0.1.0-rc.6, the web profile). It runs entirely as an out-of-tree bundle: the node half serves directory listings through its own HTTP route, the browser half renders the tree. No core changes required.

Features

• Sessions / Files tab strip injected below the New Session button (wide sidebar). The tree renders inline in the sidebar region — same presentation as the harness's own browsing surfaces.
• Lazy listing: one directory level is fetched on demand (the workspace root on open, a directory on first expand), through the plugin's own GET /dsh-sidebar-files/list?path=… route. Wire cost follows what you actually open.
• Per-extension icons: 47 brand-style glyphs for common extensions (ts/js/json/yml/yaml/css/html/md/ico/png/zip/log/…), plus a generic document fallback. Icon path data from Material Icon Theme (MIT, © Material Extensions 2025) — see LICENSE.
• Hidden by default: dot-led names, node_modules, and .git are filtered out; the 显示隐藏项 toggle reveals them. node_modules/.git stay hidden until the toggle is on.
• Row actions (hover): copy path (with one-second "copied" feedback) and send the file to the current session's agent (a queued "please read this file" prompt).
• Resilient fallback: if the shell's sidebar structure is ever unrecognizable, the plugin degrades to a footer action button + centered modal instead of the tab strip — never a blank screen.
• Bilingual (中文 / English), following the harness locale.
