Session Workbench: full-text search past sessions, recall up to 3 as @references, and manage conversation-view tabs (show/hide + drag reorder).

Search, list and read past and current sessions through the harness's own `sessionQuery` service: uses the SQLite FTS5 index where a deployment enables it, and falls back to a bounded newest-first scan where it does not.

Search stored DSH conversation text across all or selected workspaces and sessions, with exact, regular-expression, typo-tolerant or word-internal subsequence matching.

Sidebar session-search toggle between title and content: title filters by session title, content searches historical messages through DSH's built-in full-text index, grouped per session with the strongest snippet and message-type tags.

Full-text search of all local sessions: sessiongraph finds conversations in any workspace, Chinese two-character terms included; sessiongraph_index builds it.

Cross-session and in-chat keyword search with context highlighting, keyboard navigation, and instant message jumping.

Spotlight & IntelliJ-style centered search dialog for sessions and chat messages, replacing sidebar search.

Bundle for the sessiongraph capability — install this package to add local conversation-history search to a DeepSeek Harness profile

Persistent search bar in the conversation header: keyword-search the message bodies of past sessions, then open the session at the matched text.

Literal full-text search across every DSH session log (Chinese sentences work, where the built-in FTS5 tokenizer fails), as a right-sidebar panel that scrolls to the matching line, plus a session_find model tool.

Agent-facing keyword search over local DSH session logs: session_search returns matching sessions with timestamps and excerpts, session_read dumps one conversation, and both skip injected context such as memory snapshots; no index is built.

Select a statement in an AI answer, find candidate support in earlier chat and tool records, classify support, and jump to original passages for review.

Cross-session full-text search over persisted DSH session logs: builds an incremental message-level index and returns sessionId, seq, and a short excerpt; exposes an agent tool and a standalone panel. Requires Node.js 23.5+.

DeepSeek Harness agent tool (session_search) for full-text search across historical sessions backed by core SQLite FTS5 engine without memory overhead.
