dsh-sidepanel

A Codex-style right side panel for the DSH (DeepSeek Harness) web UI at http://127.0.0.1:3080/: an Artifacts view and a Side chat, both bound to the current task session. Ships as a static profile plugin that auto-loads with DSH — no core code changes.

• Artifacts: folds the session log (~/.dsh/sessions/…/session.jsonl.zstd, multi-frame zstd) and lists every file the session created or modified through write / edit / str_replace_editor tools — name, kind, path, size, mtime, source, change count. Search, source filter, copy path, reveal in Finder, safe text/code/Markdown/image preview, and an opt-in workspace mtime scan that catches bash-created files.
• Side chat: a continuable fork subagent child (native ctx.subagents) — inherits the session's completed-turn context and model, never touches the main transcript. SSE streaming, stop, retry, interrupted markers, replay across refreshes and DSH restarts. A persona keeps it answering directly instead of running off on tool sprees.
• Panel: toggle button in the session-header utilities (top-right); dock mode appends a fourth track to the frame's inline grid-template-columns so the main content is squeezed, never covered; narrow viewports fall back to a shadowed overlay. Drag or ←/→ to resize; Esc closes preview → clears search → collapses the panel and restores focus. Open/width/tab/scan persist in localStorage.

Install

cd <this directory>
node scripts/install.mjs              # idempotent: symlink + cordis.patch.yml insert row
node scripts/install.mjs --restart    # also kickstart DSH so it loads immediately
curl http://127.0.0.1:3080/sidepanel/health   # → {"ok":true,"addon":"dsh-sidepanel",...,"chat":true}

Enable / disable / uninstall

• Enabled = installed (insert row + symlink present).
• Disable: remove the - id: sidepanel / name: dsh-sidepanel row from ~/.dsh/profiles/web/cordis.patch.yml, then launchctl kickstart -k gui/$(id -u)/com.deepseek.dsh.
• Uninstall: node scripts/install.mjs --uninstall (removes the row and symlink, restarts DSH).

See README.zh.md for the full troubleshooting table and known limitations (Chinese).

Tests

node --test test/host.test.mjs test/safety.test.mjs test/client.test.mjs

Covers artifact attribution folding, fork seed boundary (seedLength), path containment math, real-filesystem preview safety (traversal / symlink escape / mismatched ids), multi-frame zstd, panel state sanitization and persistence, grid-track math (dock/overlay/closed), the chat state machine, and idempotent slot registration.

What's new in 1.1.0

• Side-chat model picker: a model button above the composer opens a listbox populated from the same LLM catalog the main chat uses (via the harness llm service). The current model is highlighted; "Follow main chat" restores the inherited routing. The choice persists in localStorage["dsh-sidepanel.v1"].
• Switching takes effect on send: the send payload carries the chosen model. The harness pins a child's routing at creation (followup cannot change it), so a different routing transparently starts a new fork child; older side-chat exchanges are preserved and merged in replay order.
• Send-to-bottom & smart scroll: after sending, the view sticks to the newest message; streaming keeps following while pinned to the bottom; scrolling up pauses auto-follow (no more yanking), showing a "Jump to latest" pill until you return to the bottom.
• New host route GET /sidepanel/chat/models; POST /sidepanel/chat/send accepts an optional model; /sidepanel/chat/state merges multi-child replays and reports childModel.
• 26 unit tests (model catalog normalization, stick-mode math, persisted-choice sanitization added).
