Give an agent a face: the DeepSeek Harness plugin

dsh-plugin-mynah lets a DeepSeek Harness agent drive a Mynah digital human: make it speak to the person watching, wave, interrupt, list who is connected, check health, feed the knowledge base. Repo: github.com/honwee/dsh-plugin-mynah.

Tools

Tool	Does	Needs admin login
mynah_speak	avatar says text; echo verbatim or chat through Mynah's brain; queues behind the current sentence unless interrupt=true	no
mynah_action	gesture such as wave	no
mynah_interrupt	stop talking	no
mynah_sessions	live sessions and their ids	yes
mynah_channels	published channels, URLs, available gestures	yes
mynah_status	health of core / engines / ASR / TTS / DB	yes
mynah_kb_add	add a text document to a knowledge base	yes

Install

dsh plugin --profile web add dsh-plugin-mynah

Then point it at your instance in the profile's cordis.patch.yml (or MYNAH_URL, MYNAH_ADMIN_URL, MYNAH_USER, MYNAH_PASSWORD in the environment):

- id: mynah
  name: dsh-plugin-mynah
  config:
    baseUrl: https://your-mynah:8443
    adminUrl: https://your-mynah:9443
    username: admin
    password: "********"

Open a channel page, click 开始对话, and ask the agent: "find the live Mynah session, wave, introduce yourself, then report system health."

Latency, measured

On the public demo (Qwen realtime brain): request to first cloud audio 0.37–0.52 s, to first lip-synced frame 0.73–1.07 s. Most of what you perceive in an agent demo is the agent's own reasoning between tool calls, not the avatar.

Other agent frameworks

The plugin is a thin wrapper over five HTTP routes; porting it to another framework is an afternoon. See Embed, level 3.
