Chat Find adds a browser/IDE-style find bar to the DeepSeek Harness conversation view. It searches every rendered chat node — user messages, assistant output, tool cards, and older pages already loaded into the transcript — without touching the composer draft or the find bar itself.

Features

• Open with Ctrl+F / Cmd+F or the find button in the conversation header.
• Esc closes from anywhere, including while the search input or the composer has focus.
• All rendered chat nodes are searched: user messages, assistant text, tool cards, and paginated history already in the DOM.
• Match case (Aa) and whole word (ab) toggles for error codes, function names, and API identifiers.
• Live n / total count, with Enter / Shift+Enter navigation that wraps at both ends.
• F3 / Shift+F3 and Ctrl+G / Ctrl+Shift+G do the same as the next/previous buttons.
• Search history with ArrowUp / ArrowDown: newest first, deduplicated, and the in-progress draft is restored when moving past the newest entry.
• Zero-result feedback: the count and bar border turn red and the bar shakes once. Repeatedly pressing Enter shakes it again. Motion is disabled under prefers-reduced-motion.
• Streaming-aware: a debounced MutationObserver re-runs the search while a response streams or older pages load. The active match is anchored by its text node and offset, so newly prepended history or appended tokens do not move the cursor to a different match. Re-searches never take over the scroll position.
• Scoped safely: input fields, contenteditable drafts, hidden nodes, and the plugin's own bar are excluded, so draft text cannot create ghost matches.
• Theme-native UI built from --dsw-alias-* tokens, with English and Chinese copy.

Requirements

• DeepSeek Harness Desktop with a Chromium engine that supports the CSS Custom Highlight API (Chromium 105+).
• Tested against DeepSeek Harness 0.2.1-rc.5.

Install

Clone the repository somewhere stable:

git clone https://github.com/bulzz1233/dsh-chat-find.git

Then install the folder as a bundle in the current DSH profile. From a DSH session, ask the agent to install the local bundle, passing the absolute path, for example:

Install this local plugin bundle: /absolute/path/to/dsh-chat-find

The agent uses plugin_manager with install_bundle and the absolute directory. The bundle is linked into the profile, so later git pull updates are picked up after the client reloads.

If the plugin does not appear immediately, reload the DSH window once.

Usage

Action	Shortcut
Open find bar	Ctrl+F / Cmd+F, or the header find icon
Close	Esc
Next match	Enter, F3, Ctrl+G
Previous match	Shift+Enter, Shift+F3, Ctrl+Shift+G
Previous / next search term	ArrowUp / ArrowDown
Toggle match case	Aa button
Toggle whole word	ab button

The active match is highlighted in the brand color; all other matches use a translucent brand highlight.

How it works

• Text is collected from the active [data-conversation-scroll] view, using the rendered conversation.chat.flow subtree.
• Text nodes are joined into a logical string with block boundaries preserved, so matches can cross inline <span> boundaries (useful for syntax-highlighted code) without matching across unrelated blocks.
• Matches are painted with CSS.highlights and Range objects rather than <mark> elements, so React-owned DOM is never mutated.
• The active match is identified by { text node, offset }. On a mutation-triggered rescan, that identity is looked up again before any index fallback, and the view is not scrolled.
• The search bar itself is a root-level overlay; the header trigger lives in conversation.session.header.utilities.

Limitations

• Only text that is currently rendered is searchable. Virtualized or collapsed nodes that are not mounted cannot be matched.
• The query is literal text, not a regular expression.
• JavaScript/Unicode word boundaries are used for whole-word mode; this is not a language-specific tokenizer.
