Awesome DeepSeek Harness Plugin

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).

Adds an archived-sessions page in Settings to search, restore, and delete archived DeepSeek Harness sessions by workspace.

Session-level superagent: watch one GitHub repository and wake this session when an issue or pull request changes; requires a logged-in gh CLI, and the credential never reaches the model.

Conversation rewind: one click back to any earlier user message, in the same window — no new branch, no leftover copy; the target message is refilled into the composer, with optional workspace-file restore — the full Claude Code /rewind semantics.

Adds /btw for one-off, context-aware side questions without tool execution, with independent answer bubbles that can be copied, collapsed, or closed without adding answers to the main conversation.

Same-origin in mechanism with the two loudest lines in context compression. The code-skeleton gate follows the skeletonization approach of Headroom (Apache-2.0), whose published headline is 20% fewer tokens for coding agents and 60–95% fewer tokens for JSON, same answers. The estimator channel follows TokenPilot (arXiv:2606.17016), which reports up to 60% lower cost for long-session agents. Both figures are theirs, quoted as-is; this plugin ships no benchmark of its own and claims no reduction of its own. What it adds for DeepSeek Harness: choose a compression profile, set the Auto Compact trigger level and toggle code-skeleton compression from one settings section, with exact DeepSeek V4 tokenizer measurement, same-revision count verification, and fail-open behaviour that keeps the original tool results on unsupported models. Within a turn it supports skeletonized information compression with a low original-text retrieval rate; at the tail of a turn it supports a turn-tail intent summary implemented purely by content substitution; context content stays safe, and the whole process runs inside the official JSONL compression.

Import full-fidelity chat histories from 13 coding agents (Claude Code, Codex, ChatGPT, Cursor, Gemini, opencode, and more) as resumable DeepSeek Harness sessions, with reverse export back to Claude Code.

DeepSeek Harness session and workspace manager —— Workspaces: archive and visibility. Sessions: move, migrate presets, delete, favorite, review later, prioritize, tag, and annotate. Batch operations.

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.

Sidebar session search that builds its own index instead of reusing DSH's full-text one: title to content toggle in one entry, results grouped per session with the strongest snippet and user/reply/tool tags, plus watermark-based incremental sync, archive-driven pruning of archived sessions, and a shadow rebuild that never blocks the live index.

Peak-hour auto session gate: weekend mode + global peak auto-pause + session-level freeze/resume + backend auto-retry, auto-resume on off-peak.

One header button stops running turns, goals and background jobs and writes the plan to disk; after a restart the same button picks the work up again.

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

Sidebar session management for DeepSeek Harness: workspace groups sorted by latest activity, history folded behind one control, a global pinned section, running/unread/follow-up marks, delete into a restorable trash whose panel also manages archived sessions, per-session token statistics split by tool (arguments vs results), moving a session to another workspace, and a scan that re-attaches sessions missing from every workspace.

One-click prompt enhancement in the composer — rewrites the draft into a structured prompt (role and goal, executable steps, output format, acceptance criteria, edge cases) with before/after preview, fill-back, and undo. Never changes intent, never fabricates requirements.

DeepSeek Harness Default System Prompt Management Plugin: Browse, search, and override the final system prompt assembled into each session round within the Web GUI "Settings".

Recall any user message: rolls the conversation (official session fork) and workspace files (per-message shadow git snapshots) back to before it, with a diff-preview confirmation panel.

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.

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+.

Rewind conversation and workspace state, powered by a persistent Change Ledger.

DeepSeek Harness plugin: restart without losing work. It waits until every conversation is idle, restarts the host, and picks the interrupted work back up instead of dying with it; where a supervisor already manages the host it asks that supervisor, and it never starts a second host next to a running one. It also fixes a common one: stale login cookies pile up on every launch until the request header overflows and the host will not start; the plugin clears them before each restart. Every restart is preceded by a snapshot of the configuration and the installed plugins - 2 are kept by default, up to 10 are allowed, and old or incomplete ones are pruned. That snapshot is never applied automatically: the plugin does not watch the host and does not restore anything on its own; it is only there for you to look at, or to roll back by hand. When the work is done it counts down and powers the machine off, so nobody has to stay up at night. It works on the Windows desktop client, and on a hosted dsh web instance - verified on WSL with systemd; Windows-hosted web, WSL without systemd, and native Linux are untested.

Delete a DSH conversation from its sidebar menu or the conversation header, optionally cascading into that conversation's associated memory nodes when you tick the box (the confirmation dialog shows the hit count before you commit); deletes land in a plugin recycle bin with restore, every action is appended to an audit log, and batch deletes are rate-limited with per-conversation rollback.

Session management for DSH: archive/restore, batch & conditional delete, AI auto-rename, interrupted-session auto-resume, workspace grouping, undo last message, repair damaged session logs (seq-gap/EIO/dual-format), value analysis and full-text search — plus plan/closing template injection (system prompt + context).

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