channels

DeepSeek Harness DSH Bundle — built-in messaging channels:

• Weixin / 微信
• QQ Bot
• DingTalk / 钉钉
• Lark / Feishu / 飞书
• Telegram / 电报（Bot API）

Install

npx @deepseek-ai/dsh plugin --profile web add -w @wsz987/dsh-channels@latest

The profile directory is itself a pnpm workspace, so -w (--workspace-root) is required to add the bundle to the workspace root (otherwise pnpm fails with ERR_PNPM_ADDING_TO_ROOT). @latest selects the stable release. Run npm view @wsz987/dsh-channels dist-tags to inspect the current beta and latest targets.

The bundle patch (cordis.patch.yml) references only entrypoints exported by @wsz987/dsh-channels itself. Those entrypoints delegate to the ChannelService, generic-file extension, Harness bridge, control plane, Web settings panel and the five channel adapters through the bundle's own dependency tree. Every channel can be disabled through its plugin config.

Quick start

# 1. add the bundle to a profile
npx @deepseek-ai/dsh plugin --profile web add -w @wsz987/dsh-channels@latest

# 2. confirm the merged config inserted the channel plugins
npx @deepseek-ai/dsh --profile web --dump-config

# 3. start the profile — all five channels load
npx @deepseek-ai/dsh web

Update and uninstall

# Install or switch package.json to the latest stable release
npx @deepseek-ai/dsh plugin --profile web add -w @wsz987/dsh-channels@latest

# Update within the package.json semver range
npx @deepseek-ai/dsh plugin --profile web update -w @wsz987/dsh-channels

# Remove the bundle; also remove any channels-* overrides from your profile patch
npx @deepseek-ai/dsh plugin --profile web remove -w @wsz987/dsh-channels

Disable a channel you don't use by setting its plugin enabled flag to false in your profile patch, e.g. plugins.channels-weixin.enabled = false. See apps/example/minimal-profile/ in the repository for a reference profile.

Verify your install

Use a clean profile to confirm the bundle loads end to end (never reuse a dirty profile for release validation):

# 1. add the bundle to a clean profile (auto-initializes it on first use)
npx @deepseek-ai/dsh plugin --profile release-validation add -w @wsz987/dsh-channels@latest

# 2. dump the merged config — verify the channel plugins were inserted
npx @deepseek-ai/dsh --profile release-validation --dump-config

# 3. start the profile — channels-service / -harness / -control and the five
#    adapters (plus channels-web) should all load without error
npx @deepseek-ai/dsh --profile release-validation

Dependencies

The bundle owns every Harness loader entry and its Web client face. Its npm dependencies provide the implementations behind those entries, so you only ever install @wsz987/dsh-channels:

Package	Role
@wsz987/channel-core	Cross-channel contract + ChannelService (ctx.channels)
@wsz987/channel-harness	Harness bridge (SessionBinding, AgentManager, reply pipeline)
@wsz987/channel-control	Config / credentials / auth-session control plane
@wsz987/channel-files	Optional generic-file extension (store / extract / read_channel_attachment)
@wsz987/channel-web	Web dashboard (Settings > Channels) for GUI setup
@wsz987/channel-weixin/qq/dingtalk/lark/telegram	The five channel adapters

The Web dashboard (@wsz987/channel-web) declares one dynamic client dependency (@deepseek-ai/dsh-client-locale, provider of the locale service); React, @deepseek-ai/cordis and the static UI libraries (-ui-primitives, -ui-slots) are shell-owned identities the Harness web app compiles in — nothing extra to install for that panel beyond a Harness version that ships them.

Selecting adapters

The individual adapter packages do not currently carry their own dsh.bundle profile patches, so installing one with plugin add is not a complete Harness setup. Install @wsz987/dsh-channels, then disable or override unwanted channels-* rows in the profile patch. See apps/example/minimal-profile/ for the complete row shapes.

DeepSeek Harness Agent / Session

• Adapters never touch ctx.agents.
• The Harness bridge is the only place allowed to import Harness public APIs.
• Replies flow from session/event back through the bridge to the adapters.
