Sessions & Messages

Read-only session-log projector (drsc) for DSH: scans ~/.dsh/sessions/**, decodes zstd/tiled-frame logs with a vendored leaf decoder and rewrites per-session projections into its own SQLite (node:sqlite, segments / replaces + FTS5), exposed through a single fenced HTTP route — surface ledger, recall/compression pair accounting and Chinese-capable full-text search. Token counts share the exact DeepSeek-V4 tokenizer and formula as CCI verify, falling back to a labelled chars/4 basis when assets are absent. Never writes session files; all output lands in its own data directory. Serves three consumer plugins: context-compression-improved (surface marking + recall reconciliation), session-steward (search-corpus switch), prime-memory (historical anchor backfill). Hosts 0.1.0-rc.2 .. 0.2.1-rc.2 (17-tag exact engines.dsh enum). npm: dsh-reference-session-collector.

Cross-session task delegation for DeepSeek Harness: spawn durable top-level sessions and send them tasks, read or steer them by base62 session alias, and approve their sandbox escalation requests through an approval bridge that refuses destructive deletes.

Talk about everything in one chat (the main chat): each message is routed automatically to the topic it belongs to, each topic runs in its own background session with its own context, and existing DSH chat history is organized into topics.

Message-level rollback, single-message deletion, and replay-based restore for DSH sessions; operations are append-only surface replacements, with confirmation prompts and a running-session guard. Requires Node.js 23.5+.

Compresses DSH time-context from ~280 chars to 46 chars by injecting a compact date line into the runtime-context snapshot; zero runtime dependencies.

Smart session titles for DSH: after each conversation turn an independent auxiliary LLM call summarizes the full user+assistant transcript into a title that follows the session's real topic instead of echoing the first message; the first message is titled instantly, failed built-in titles auto-retry on later turns, manual renames are never overwritten, and subagent/fork sessions are skipped.

Auto-resume for interrupted agent sessions: an ordered rule table routes by failure type (rate limit, quota, auth, context overflow, crashed orphan) to automatic backoff retry, model switch, resume after context compaction, or a stop-loss notification, with a visual rule editor and a full activity log.

Switch the language of the agent's thinking/reasoning process (chain-of-thought): 简体中文, English, Русский, Français, Deutsch, Español, 日本語, 한국어 and more, or auto-follow the system locale. Adds a Settings → General row, a system-prompt instruction (per-prompt assembly, applies to new sessions), and the /thinking-language command.

Move, archive, restore, portable backup/export and import sessions across workspaces in the DeepSeek Harness web UI.

Pause / resume / cancel the in-flight conversation task from the composer area: forced pause interrupts immediately and remembers the interrupted tool, safe pause lands after the tool or reasoning finishes, resume asks for confirmation, and the default pause granularity is configurable in the settings.

Bookmark assistant replies with notes and tags; browse every bookmark in one cross-session center and export to Markdown.

Replaces the dsh compaction backend with a Codex-style window reset: the checkpoint is a handoff assembled from the session log by code, not a model-written summary, so a reset costs no summarization calls. A task ledger with a two-check gate keeps intent, next steps and the files still in play across resets, and a new_context tool lets the model reset on its own. Re-declares the four built-in agent presets (standard, ptc, minimal, cordis) exactly as shipped in dsh 0.2.2-rc.1, so re-run sync-presets.mjs after a dsh upgrade; idle cache keepalive is on by default and sends real requests that use quota (keepalive: false turns it off).

Session Manager for DSH (formerly Session Steward): one console over active and archived sessions — grouped by workspace, domain and title filters, favorites, and batch archive / unarchive / purge archived files (destructive steps ask twice) — plus a four-gate health checkup (log integrity, projection cache, lossless JSON, cold read) that ends in a reversible, backup-first prescription. Search and indexing live in dsh-search-index; this plugin builds no index and never rewrites session logs.

Adds a trash for DSH sessions: nothing expires automatically. Delete or batch delete moves sessions there, where you can read, restore, or permanently delete them.

Delete a session from the UI (session-header button or sidebar row menu) or with the session_delete tool: stops and releases a running agent and its live session first, then removes the log directory, projection cache and workspace accounting, and cascades into the subagent sessions it owns while leaving forked branches untouched.

Imports local coding-agent session histories so work can continue in DSH.

DeepSeek Harness adapter for Context Mode: in-process ctx_* tools for sandboxed code execution and an FTS5 knowledge base, plus context-window routing guidance.

Git-style conversation branching that mirrors how real programmers collaborate: a secretary root branch dispatches tasks to child branches with their own contexts, merging back only compressed summaries via squash or rebase; ships /branch commands, a branch tab, branch-to-branch messaging, and a governance baseline pairing each session branch with a git worktree.

Manage conversation records from the DSH web GUI settings page: delete a whole session (archive plus physical log removal) or a single message (deleting a user message cascades to its assistant replies and tool results). Running and current sessions are protected.

Cross-session agent messaging for DeepSeek Harness with session discovery, offline delivery, delivery receipts, and sender-session navigation.

Import claude-code / codex / reasonix / zcode chat history into dsh sessions: workspace binding, tool calls preserved, oversized-session protection, zcode compaction restore.

File claim/release protection for parallel DSH sessions on the same workspace (heartbeat stale takeover, pending 3-way merge area).

Bring the deepseek.com web/app chat experience to DSH: edit your prompt and regenerate answers in place, with a per-message <i/N> version pager (tree model, stable across conversations).

A visual map for your sessions: every conversation is a card on an infinite whiteboard — workspaces become frames that fold their overflow into a drawer, card positions are never rearranged, lines between cards carry context (drag one to fork with an injected digest), and each card shows a status lamp for running, waiting, unread or interrupted.
