Agent teams: spawn named long-lived teammates, coordinate them with a shared task list, member mailbox, and virtual workspaces, and watch the team live in a team-room tab.

Runtime extension suite for DeepSeek Harness: cross-session mailbox with wake cold-start, agent teams (captain + members + dependency task board + team_wait), subagent spawn policy with escalation approval, task-aware routing preset, plugin market, skill manager and runtime injector.

Orchestrates durable multi-agent teams from one DSH session: a captain spawns member subagents, drives a dependency-aware task DAG with quality gates, and coordinates through persistent mailboxes, with a live activity panel.

Verifies letters signed by other agents: a canonical field order, digest and HMAC checks, and fail-closed handling of missing or unregistered fields. Off by default; when enabled, a letter that fails any check is refused rather than delivered.

File-backed post office between DeepSeek Harness sessions: every letter is sealed with an HMAC and a body digest, recipients are resolved through a roster interface, and delivery is offline-first, so an undeliverable letter waits in the mailbox instead of being lost.

Daily sending quotas and quiet hours for agent mailboxes: letters are counted in named buckets that each carry a per-day limit, the day boundary is configurable, and a quiet window tells the core to hold online letters rather than deliver them.

Kizuna agent letterbox: four tools that let an agent read its own inbox (mailbox status, pending letters, one letter in full) and answer a letter with completed / failed / input-required / working state. Kizuna is an agent directory with a reliable task relay: a per-agent kizuna-box on the same machine holds the inbox, retries unanswered deliveries after 3 / 10 / 30 / 60 / 120 minutes and records every delivery attempt in an append-only trail. The plugin talks to the local loopback box only and holds no credential.

dsh (DeepSeek Harness) 跨 agent 信箱插件：让 dsh 会话内的 agent 通过 agent-mailbox 与本机其他 agent（Claude Code / OpenCode / Hermes…）互发消息、收任务卡、卡动即唤醒。零 npm 依赖，Node 22 即装即用。

An AI collaboration mailbox in DeepSeek Harness for messaging, task handoffs and delivery receipts. One package includes MCP integration and a mailbox UI. Version 0.2.2 requires DSH 0.2.0-rc.2. Requires a separately installed Agent Mail 1.0.0-alpha.7 provider; no automatic model wake or continuous online status.

DailyBoard — a daily work task board for the DSH Web GUI with a one-month calendar of colored timeline bars and day tasks, a daily checklist, a seven-day week view with completion checkboxes and drag-to-reschedule, a draggable 24-hour day timeline, ordered per-day subtasks, weekly and every-N-days recurring tasks with per-occurrence result records, a long-term progress view opened from the calendar header, per-day completion for long-term tasks, a collapsible daily email reminder for any mailbox, and AI extraction of tasks from natural language.

IMAP mail triage and cleanup for DeepSeek Harness: incremental read-only scan, a hard-protection rule layer plus optional local-model classification, a Markdown report and a hashed manifest, an explicit approval card, and only then a move to the Trash mailbox — no expunge.

Mailbox for DeepSeek Harness: sessions pass letters through a shared folder, and an hourly randomized scheduler can wake a session on its own (mutual letters between two sessions, or a gentle nudge to the owner). Per-recipient hourly rate limit and a UTF-8 log.

Runs the local Codex CLI from DSH as four tools (codex_run, codex_resume, codex_queue, codex_probe), and ships a standalone loopback bridge with an HTTP API and a file mailbox.

Personal task board for the DSH Web GUI with a one-month calendar of colored timeline bars and day tasks, a daily checklist, a seven-day week view with completion checkboxes and drag-to-reschedule, a draggable 24-hour day timeline, ordered per-day subtasks, weekly and every-N-days recurring tasks with per-occurrence result records, a long-term progress view opened from the calendar header, per-day completion for long-term tasks, a collapsible daily email reminder for any mailbox, and AI extraction of tasks from natural language.

Emails you when a long turn finishes or errors, when a goal completes or blocks, and when an approval or a question has waited past a timeout; each new notification deletes the previous one from the inbox over IMAP, so the inbox holds at most one.

QQ Mail (and any IMAP/SMTP mailbox) for DeepSeek Harness: registers qqmail_* agent tools that list, search, read, send, reply to, flag and download mail through IMAP/SMTP with a QQ Mail authorization code (no OAuth, no 2FA redirect), plus a `qqmail` CLI a
