omdsh-sidepanel

The DeepSeek Harness web GUI gives you a tidy three-column frame—session list, conversation, details—but leaves a practical gap: nowhere to peek at the project's files and nowhere to run a quick command. omdsh-sidepanel fills exactly that gap with a right-edge file explorer and a bottom terminal, both scoped to the working directory of the current Work-mode conversation. Open them when you need them, collapse them when you don't, and in Chat mode they simply do not exist.

The file panel lists one directory level, previews a single text or image file on click, and lets you copy a path via the header button or a right-click menu. No editor, no git view, no tab strip—just a readable 320-pixel column. The terminal runs on node-pty so that a conversation's shell survives switching sessions, collapsing the panel, or even reloading the page; when you reconnect, the transcript replays and you land mid-command rather than at a fresh prompt. Both panels have an 8-pixel drag grip for resizing and a double-press to snap back to their shipped size, with dimensions stored in the browser's localStorage.

It is built for the "I just need one file or one shell next to my conversation" moment—developers who do not want a full IDE open but also do not want to hop to a separate terminal window to glance at a directory listing. Path and shell access are fenced to the session's working directory, keybindings are delegated to the omdsh-shortcuts service rather than hard-coded here, and the plugin contributes nothing to Chat mode.
