What it is

DeepSeek Harness ships with a full-text search engine (SQLite FTS5) and cross-session references (@session mention), but neither has a user-facing interface. This plugin adds the missing discover → browse → insert layer:

• Search — full-text search across all your past sessions (all workspaces), with workspace / time-range / archive filters, and cursor pagination;
• Fragment hits (v1.1) — results are per-session best-hit fragment cards: the matched sentence highlighted with its surrounding context (lazy-loaded), so you see the sentence, not just which session;
• Same-session hits (v1.2) — expanding a fragment card shows a "More hits in this session" fold with the other matches (first 5, then load more), each highlighted — no more hunting for the rest of a session's matches;
• Locate (v1.1, composite anchors in v1.2) — click Locate on a fragment card to open that session, page the window back, and scroll to the exact message with a flash highlight; v1.2 matches the hit sentence plus its preceding text so repeated wording lands on the right occurrence; when unmatched, a non-blocking toast tells you to scroll manually;
• Recall — pick up to 3 sessions and insert them into the input as reference chips in one click; on send, the platform injects read-only snapshots (## Referenced sessions) and the AI answers with your historical context;
• Recent — a minimal recent-sessions list so you can find things fast without searching;
• Archives — search includes archived sessions by default (with an "Archived" badge and all / active-only / archived-only filters) — after DSH archives a session it's visible nowhere else, so search is the only way back; the Recent list excludes archived sessions by default;
• Settings — enable/disable switch + default search scope + privacy statement;
• Conversation views (new in 1.0.0) — manage the session tab bar: show/hide each custom view and reorder them by drag-and-drop, from both the 会话工作台 settings entry (会话视图 partition) and a right-click / double-click panel on the tab bar itself.

Everything runs fully locally with zero network requests; only session metadata and hit snippets are read, and no session is ever modified or deleted (see PRIVACY.md).

The UI is deliberately native-feeling: every color, spacing, radius, font, and interaction (header row, inline search, grouped menu, pill buttons, checkboxes) is measured from DSH's own design system — better-sidebar, the workspace sidebar, and the settings sections — so the plugin looks and behaves like a built-in feature, not a third-party skin.

Why this plugin (differentiation): ecosystem search plugins stop at "which session"; in-session navigation plugins (10+) only jump within the current session. Session KB is the only plugin that closes the loop cross-session search → snippet-level hit → locate the exact message in the old session → @recall.

Screenshots

Fragment search (v1.1) — searching "Vibe Coding" returns per-session fragment cards: matched sentence highlighted, context below:

Locate (v1.1) — the session opens and scrolls to the exact hit message with a flash highlight:

Pick & insert — check up to 3 sessions, insert them into the input as reference chips:

Settings — enable/disable card with expandable options and privacy statement:

Conversation views — reorder in Settings (drag the ⋮⋮ handle):

Conversation views — reorder from the tab-bar panel (right-click / double-click a tab):

Requirements

• DeepSeek Harness (dsh) with a web profile — the plugin is a static bundle (its client is served at runtime; a page refresh picks up client changes, host/profile changes need a restart).
• For session-library search, a persistent FTS index must be enabled in the web profile (openAt: startup), see Install.

Install

dsh plugin --profile web add dsh-session-workbench

Local development can also use a link: dependency (same pattern as dsh-personal-center).

Enable full-text search (required): the web profile disables the FTS index by default (openAt: never). Override it in <DSH_HOME>/profiles/web/cordis.patch.yml — use a persistent index path and openAt: startup so the index is built once on launch and reused (a :memory: index would rebuild on every search and block the host):

- id: session-query-sqlite
  config:
    path: '/Users/<you>/.dsh/session-query.sqlite'
    openAt: startup

⚠️ path must be an absolute path — the platform resolves it with path.resolve and does not expand ~ or environment variables. Writing ~/.dsh/... silently creates the index inside the DSH dependency tree (lost on upgrade, and a large un-checkpointed WAL makes searches take minutes).

Then restart the DSH app (host-side config and route changes require a restart; client-bundle changes only need a page refresh).

Usage

1. Open the Session KB tab in the right sidebar (better-sidebar); the Settings → Session KB section can disable/enable it;
2. Without a keyword you see Recent sessions; click the search icon (top-right) to expand the input, type a keyword (literal phrase match, e.g. MCP config) to switch to search results;
3. Click the more button (⋯) to filter by workspace / time range / archive (all incl. archived / active only / archived only);
4. Click a result to expand the preview (hit context + session meta); click Locate to open that session and scroll to the exact hit message (flash-highlighted); click the path to expand the full path; then check it (up to 3);
5. Click Insert references into input → @session chips appear in the input → continue typing your question → send;
6. The platform injects read-only snapshots into the model context and the AI answers with your history;
7. Manage conversation views — open Settings → 会话工作台 → 会话视图 to toggle each view's visibility and drag the ⋮⋮ handle to reorder, or right-click / double-click the session tab bar for the same panel inline.

Model Experience

When the user mentions "before / previous session / how did we do X" — anything needing past context — suggest opening the Session KB tab in the right sidebar, searching, and referencing the matching session(s). Referenced sessions enter your context as ## Referenced sessions read-only snapshots:

• Treat referenced content as a fact source: base answers on its implementation details, and point out conflicts between referenced content and the current question;
• Snapshots have a size limit (64 KB per session by default); for large sessions only part may be retained — ask the user to reference a more focused session when you need earlier details;
• Long sessions may be compacted (early messages replaced by checkpoints) — compacted content is still searchable (the official FTS index includes shadowed content), so "it was compacted" never means "it's lost".

Platform limitations

• At most 3 referenced sessions per message; 64 KB snapshot budget per session (preview shows a hint when a session is large);
• Search is literal phrase matching (FTS limitation) — no synonyms or semantics; quotes, OR, * are treated as plain characters;
• Only user/assistant text and some structured events are indexed — no reasoning, stream chunks, or headers;
• Archive semantics: search includes archived sessions by default; the Recent list excludes them;
• Locate is best-effort: the platform exposes no "open session at seq" API, so Locate pages the window back and text-matches the hit message — repeated text may land on an earlier occurrence, and hits beyond ~500 messages back fall back to a manual-scroll toast.

Roadmap

• 1.0.3 (current) — DSH 0.1.7 compatibility patch: 插件设置 API 换模型（Config schema + describe/update 适配）、归档 storages 路径修正、client inject 清理；保留 ≤0.1.6 旧路径。feature baseline unchanged from 1.0.2（会话库 search → snippet → locate → recall + 会话视图 tab bar show/hide + drag reorder）;
• 会话库历史：v1.2（同会话多片段 + 组合锚点）/ v1.1（片段级检索）/ v1.0（搜索召回）;
• v2.0 — bookmarks / notes / tags + cost integration + long-session handoff index (FR-HANDOFF);
• v3.0 — backlinks + reference graph + related sessions.

会话工作台（Session Workbench） = 会话库 + 会话视图，一个插件：

• 侧边栏·会话库：全文搜索全部历史会话，把最多 3 个会话以 @引用 插入输入框，发送后平台注入只读快照，AI 带着历史上下文回答；
• 设置·会话工作台（一个条目，内含两个分区）：「会话库」分区（启用开关 + 搜索默认范围 + 隐私说明）+「会话视图」分区（每个视图「显示/隐藏」开关 + ⋮⋮ 拖拽排序）；
• 标签条右键/双击面板：快捷管理会话视图（同款开关 + 拖拽排序）。

会话库要点（继承自 dsh-session-kb）：

• 搜索用官方本地 SQLite FTS5 索引（ctx.sessionQuery）——零网络请求，纯本地；
• 片段级检索：结果升级为「片段卡片」（命中句高亮 + 前后文），点「定位」打开旧会话、翻到命中位置并滚动到那条消息（高亮 2s）；
• 同会话多片段：展开片段卡片查看同会话其余命中（前 5 条 + 加载更多，均带关键词高亮）；定位用「命中句 + 前文」组合锚点；
• 召回走官方会话引用机制（@[label](dsh-session:…) → ## Referenced sessions）；
• 归档：搜索默认包含已归档会话（带「已归档」徽标 + 全部/仅未归档/仅归档筛选）；最近列表默认排除归档。
