dsh-chat-history

A "History" tab in the DeepSeek Harness session header: turns the user messages of the current session into a clickable directory. Click any entry to jump back to the Chat view and scroll to that message.

• Auto-generated: only real user questions (user messages) are listed — Tool / Thinking / Command / injected-context noise is filtered out, so even long agent sessions stay navigable.
• Auto-paging: while the tab is active it keeps loading older history (50 messages per page) until the whole session log is in the client window — the directory is complete without manually scrolling the chat area.
• Click-to-jump: switches back to the Chat tab, smooth-scrolls to the target message, and flashes it for 1.5s.
• Zero conflicts: registered as a conversation.view session tab (side by side with the official "Trajectory" tab) — it does not occupy the details slot, so the official tool-call detail panel keeps working untouched.

Install

# install into a profile (e.g. web)
dsh plugin --profile web add dsh-chat-history

After restarting dsh web, open any session: the header tab bar shows Chat / Trajectory / History. Click History to use the directory.

Usage

1. Open a session and click the History tab in the header. 2. The directory lists every user message in order (number + single-line truncated title; hover shows the full text). 3. The header shows loading state: "Loading earlier history…" while older pages are being fetched, or the total entry count once complete. 4. Click any entry — it switches back to the Chat tab, scrolls to the message, and flashes it.

Development

• Pure client plugin: a hand-written window.__ModuleLoader__.load({ id, factory }) bundle — no build step required.
• No restart needed after editing lib/client.js: the profile's built-in client-hmr stat-polls bundles every 500ms and hot-reloads on change (roughly 1s).
• A restart is required when: adding a new plugin package, changing the dsh.client declaration in package.json, or toggling enable/disable in cordis.patch.yml.

How it works

• Data source: session snapshot s.chat.order + s.chat.nodes.get(key), filtered to kind === "user".
• DOM targeting: ui-conversation already stamps every message node with data-chat-anchor-key — lookup by key directly.
• Paging: session.loadOlder() pulls 50 messages per page, driven by hasMore / loadingOlder; stops after 3 no-progress pages to avoid looping on a stuck host.
• Jump: since only the active view renders, first simulate a click on the Chat tab, then poll for the target DOM and scrollIntoView + flash.
