dsh-reach

English | 简体中文 | Español | Português | हिन्दी

Multi-channel decision & remote-control bridge for DeepSeek Harness (DSH): pushes any workspace's approval/question cards to IM channels (WeChat iLink, Telegram, Feishu — plus QQ/DingTalk/WeCom v2 drop-in foundations) and answers them from chat, with a session console, per-channel security, and an open push service.

Status: Phase 1–3 complete (WeChat + Telegram + Feishu channels, v0.1.18); v2 channel foundations (QQ/DingTalk/WeCom) on the open reachChannels registry. The design plan, competitor research, official contract verification, and phased roadmap live in docs/design/03-rebuild-direction-and-plan.md. Release (GitHub repo + npm publish) follows in a dedicated session.

The same run, animated.

Maintenance status: 🧊 FROZEN

Frozen on 2026-10-05. No new features. This package still works, and it is not retired — but it no longer receives feature work. Only a genuine breakage will be fixed.

Maintainers treat this capability as one where better-adopted alternatives now exist, so effort has moved elsewhere. The comparison below was measured on 2026-10-05 and is recorded so nobody has to redo it.

| | package | weekly downloads | |---|---|---| | this package | dsh-reach | 600 | | better-adopted alternative | @xmanrui/dsh-im | 17,384 |

Why the alternative leads. @xmanrui/dsh-im provides ten channels — WeChat, Feishu, WeCom, DingTalk, QQ, Telegram, WhatsApp, Slack, Discord and Matrix.

Compatibility. declares no dsh peers, so the compatibility guard never blocks it.

What this package still does that the alternatives do not. this package's differentiator was that the same bridge carried approvals and questions back into chat; the rival is far broader in channel coverage

👉 For new work, prefer @xmanrui/dsh-im. Existing installs keep working unchanged; nothing is being removed.

Compatibility

| Surface | Status | |---|---| | Harness | DeepSeek Harness dsh-v0.2.1-alpha.1 (GitHub tag).

Features (Phase 1)

• Cross-session decision push: approval/question cards from ANY workspace are mirrored to WeChat (iLink/ClawBot) with stable #token ids and P{n} numbering; reply 1/2, P1=1 P2=2, P1=Q1=2, or /rp /rq — answered through the native pending waterfall (first reply wins with the GUI).
• Fail-closed security: first sender becomes the owner; empty allowlists deny everyone; unknown senders are audited and never answered.
• Session console: /status /silent /notify /tasks /enter /history /stop /next /help plus native DSH command passthrough.
• Proactive push: the reach_send tool with an outbound file fence; rate budget + FIFO re-queue; silent mode; background completion notices.
• Settings tab: Settings → Plugins → IM Bridge (status, switches, re-scan/logout).
• Open channel registry: third-party plugins register a channel via ctx.get('reachChannels').registerChannel({ id, adapter, priority, ownsChatId, startMonitor }); routing, outbound, and monitor lifecycle are all bridge-owned (QQ/DingTalk/WeCom ride this same path).

Configuration

Interoperability with other DSH plugins

Verified against DSH 0.2.0-rc.2 (the runtime this README ships for) and the high-star plugin set surveyed on 2026-10-05.

This plugin does not interfere with other plugins, including the widely installed high-star ones:

• No tool-name collision. Every tool is namespaced; no bare name owned by a shipped tool or another plugin is registered.
• No service-key collision. It provides reach, reachChannels, reachPush; those keys are not a built-in seam and are not provided by any surveyed high-star plugin.
• No slot collision. It registers no client slot key, so it cannot contend for a shadows-shipped-ui seat.
• No HTTP route collision. It registers no webServer prefix.
• No patch-layer collision. The bundle patch only inserts its own row; it never overrides a built-in row's config.
• No global mutation. It does not patch prototypes, rewrite process.env, or replace the global fetch dispatcher.

Shared event listeners are non-interfering by construction. It observes the ordering-sensitive events approval/request, user-questions/request with ctx.on() — Cordis's broadcast registration, where every listener runs and none can starve another. Every listener here delegates through next(), so the chain is never short-circuited, and a mutation is applied to the value next() produced rather than returned in its place:

Static evidence: dsh-plugin-doctor K10–K13 report pass for every check on this repository.
