dsh-conversation-minimap

English | 中文

A DeepSeek Harness (DSH) Web GUI plugin: Prompt-based Conversation Minimap — a ChatGPT-desktop-style navigation rail for long conversations.

• Anchors: one capsule per user prompt, evenly spaced, centered in the rail
• Fish-eye: bars magnify on a Gaussian bell curve toward the right under the cursor (44px peak), stay magnified while the pointer moves inside the enlarged area, slide smoothly
• Edge fade: the rail fades at the top/bottom via a mask — overflowing anchors fade out and never exceed the rail bounds
• Position tracking: a blue glowing highlight follows the current prompt (switches when the prompt's center crosses the viewport center); after window resizes the view snaps back to the bottom and the visible anchors always follow where you are
• Interaction: hover shows the full prompt preview; click smooth-scrolls to that message and highlights it for 2s (no stuck highlights on rapid clicks)
• Full history: pulls the entire conversation via the official loadOlder API, so every prompt in a long conversation is reachable

Installation

dsh plugin --profile web add github:Braidy-Wu/dsh-conversation-minimap

Restart dsh web.

Configuration (cordis.patch.yml, all optional — restart dsh web after changes)

- insert:
    - id: conversation-minimap
      name: dsh-conversation-minimap
      config:
        enabled: true    # master switch (false = never loads)
        minPrompts: 4    # show the rail once the session has at least this many user prompts (default 4, range 0-100)
        anchorSize: 3    # anchor bar height in px (default 3, range 2-8)

How it works

• Data: pulls full history through the official ctx.sessions + conversation.loadOlder() API; observes the rendered conversation DOM — user messages carry data-chat-flow-kind="user" (and steering), jump targets use the rows' data-chat-anchor-key (the same mechanism the official UI scrolls by)
• Mounting: an absolutely positioned seat on the conversation viewport wrapper — no layout impact; edge clipping + mask fade
• Updates: MutationObserver on the message list (debounced + key-set diff, no jitter while streaming); polling handles session switches; nothing renders during history sync — the full rail appears at once
• Safety: everything is guarded by try/catch; any unexpected failure only disables the minimap, never the GUI

A plain-vanilla-JS client plugin (inject: ['sessions'], mirroring the dsh-theme-plugin shape) with no build step and no dependencies.

Development

node --check client.js index.js   # syntax check
# smoke test: test/smoke.html + python3 -m http.server
