dsh-plugin-codex-ui

The default DeepSeek Harness web sidebar crams the browsing region, global panel rows, and the New Session button into one column. If you want a clean, Codex-style two-section layout (Projects + Recents) without hand-writing CSS overlays and client patches, this plugin replaces the entire browsing area in a single install while leaving the brand row, collapse animation, 36px rail, and settings foot untouched.

Three core interactions define the experience. First, the "New chat" row starts a real session with no project: the server allocates a fresh working directory, registers it as a Workspace, and opens the composer fully live from the first keystroke. If you abandon the session without using it, the plugin archives the session, drops the Workspace, and removes the directory, so rapid-fire clicks leave at most one leftover. Second, the Projects section lists registered working directories; clicking a row folds open its chats, a plus button adds a new directory via the OS folder chooser, and a trash icon removes only the registration. Third, Recents collects every project-less chat; archiving is deliberately a two-step confirm to prevent accidental one-way deletion.

This plugin suits Harness users who prefer a Codex or Cursor sidebar shape and a "chat first, file later" workflow, or anyone who wants a visual reskin without touching the core repository. If you need the native browser extras (session search, rename, fork, drag reorder, subagent lineage), simply uninstall the plugin and the shipped UI returns immediately.
