The official billion-context plugin: a context-compression plugin for small context windows (a 100K context is enough), token savings (5x fewer tokens), and month-long single sessions (billions of tokens).

In-place conversation rewind in the same session window without forking (Claude Code /rewind semantics): a per-message ↶ button cuts the model context back to any user message, with an optional Claude-Code-style file restore from disk-persisted before-backups.

DeepSeek Harness session manager: delete, archive, move sessions across workspaces, migrate presets, favorites, review-later, search, filter, sort, prioritize, add tags & notes, and batch-manage sessions. | DSH 会话管理：删除、归档、跨工作区移动、预设迁移、收藏、待回看、搜索、筛选、排序、优先级、标签、备注及批量操作。

Session manager panel under Settings → Plugins: list all sessions with title, cwd, agent preset, updated time, turns and steps, expand a row to view message history, delete non-running sessions, and export a session as JSON or Markdown via a browser Blob URL.

Settings-page manager for archived DeepSeek Harness sessions: restore an archived session to its previous workspace position or permanently delete it (direct physical deletion, no backup layer). Adds a red permanently-delete item to the session context menu and three agent tools. Deleting an open session works immediately; the leftover in-memory copy is hidden behind an archive tombstone until the next restart.

Manages archived DSH chats with conversation search, restore, and confirmed safe permanent deletion.
