In-conversation text search for the DeepSeek Harness web UI — the Ctrl+F you already know, scoped to the current chat session. A floating search bar highlights every match in the rendered transcript and walks between them, without touching a single line of harness core code.

Problems it solves

• Long sessions are unsearchable: the browser's native find searches the whole page (sidebar, composer, chrome) and cannot follow a conversation that keeps streaming. This plugin searches only the active conversation scrollport and stays in sync while the model is still writing.
• No way to jump between occurrences: native find gives no "n / total" navigation. This plugin provides Enter / Shift+Enter and prev/next buttons with wrap-around, centering each match in view.
• Highlighting must not fight React: the transcript DOM is React-owned and re-renders continuously during streaming. Instead of wrapping matches in <mark> nodes (which would mutate React-managed text and break reconciliation), the plugin paints ranges through the CSS Custom Highlight API — an overlay that survives every re-render and needs zero DOM cleanup.

Features

• Ctrl/Cmd+F opens the floating search bar (only when a conversation is rendered — otherwise the browser's native find stays untouched); Esc closes it from anywhere, including while the input holds focus.
• Matching across every rendered chat node: user messages, assistant text, tool cards, and paged-in history. Two toggles mirror the browser/IDE find bar: Aa (match case) and ab (whole word) — essential for hunting error codes, function names, and API identifiers.
• Live n / total counter with Enter (next) / Shift+Enter (previous) navigation and wrap-around; F3 / Ctrl+G work too, the browser/IDE find-bar convention.
• Query history: ArrowUp / ArrowDown cycle through your recent queries (most recent first, deduplicated), restoring the draft you were typing when you walk back past the newest entry.
• Zero-result queries answer back: the count turns red, the bar border follows, and the bar gives a one-shot shake (honoring prefers-reduced-motion). Repeated Enter on no results re-shakes instead of staying silent.
• The active match is painted in a stronger color and scrolled into view automatically.
• The header action button mirrors the open state (aria-pressed), so you always know whether search is active.
• Streaming-aware: a MutationObserver re-runs the search (debounced) while output streams or older pages load, without stealing your scroll position. The active match is anchored by identity (text node + offset), so a paged-in older page or a streamed delta never jumps your cursor to a different occurrence.
• Scope discipline: the composer seat and the plugin's own bar are excluded, so your draft text never produces phantom hits.
• Follows the harness theme through --dsw-alias-* design tokens; Chinese/English UI picked from the document language.
• Session header action button (search icon) registered through the conversation.session.header.actions slot — the additive, unload-safe composition route.
