dsh-sidebar

DSH's web workbench already ships a right sidebar, file tree, and native terminal, but a day-to-day frontend workflow still leaves gaps: editing code in the browser, reviewing Git changes line by line, juggling multiple worktrees, and running a persistent terminal without leaving the page. dsh-sidebar slots those capabilities into the host's existing sidebar, tabs, and bottom dock — no second sidebar, no host source-code modifications.

On the editing side, CodeMirror 6 powers every text or code file opened from the host Files panel, chat file links, or tool results: syntax highlighting, line numbers, an independent undo stack, and Cmd/Ctrl+S quick-save are all there; unsaved files show a dot on the native tab, while images and PDFs keep the host's native preview. The Git surface covers unstaged, staged, a specific commit, and branch-range scopes, with per-file add/delete counts, line-level diffs, collapsible context, and a filterable changed-file tree. The commit dialog supports model-generated commit messages, commit-and-push, and push retry; a failed branch switch surfaces the reason instead of failing silently. The Worktree card lists the main tree, active linked trees, and stale records, creates new trees as persistent sibling directories with their own branches, and reuses or creates a Session at the target path — uncommitted changes stay in the original tree.

The terminal runs xterm.js over a persistent zsh PTY in a dock below the chat input, resizes smoothly with the conversation area, supports multiple tabs, draggable height, and full ANSI/256/True Color output. Ideal for developers who already work in DSH's web workbench and want the full edit → review → commit → switch-worktree → run-terminal loop to stay in the browser without forking the host. The plugin relies only on the host's public Sidebar, Slot, Session, fs, subprocess, and Client Module APIs, requires DSH ≥ 0.1.6-alpha.1, and is distributed under the MIT license via npm.
