# 在 Harness profile 的 node_modules 下
cd ~/.dsh/profiles/<你的profile>/node_modules
npm install hermes-dsh-bridge

git clone https://github.com/Emilia-awa/hermes-dsh-bridge.git
cd hermes-dsh-bridge
npm install && npm run build   # 产出 lib/index.js
# 把构建产物放进 Harness profile:
#   ~/.dsh/profiles/<你的profile>/node_modules/hermes-dsh-bridge

# ① 安装插件到 profile
cd ~/.dsh/profiles/<PROFILE>/node_modules
npm install hermes-dsh-bridge        # 未发布到 npm 前用方式 B（源码）

# ② 修复 dual-package hazard: 把所有 @deepseek-ai/* 和 cordis-plugin-* symlink 到全局树
GLOBAL_TREE=$(npm root -g)/@deepseek-ai/dsh/node_modules/@deepseek-ai
for pkg in cordis cosmokit dsh-agent dsh-llm dsh-session dsh-tools dsh-scope \

        provider: opencode-go      # ← 换成你自己的 provider id
        model: deepseek-v4-flash   # ← 换成你自己的 model id

# ④ 重启 Harness(注意: 若你正跑在 Harness 里, 用 systemd-run 脱离进程树重启)
systemctl restart dsh.service

# ⑤ 验证: 等 8 秒后检查 MCP server 起来 + 工具列表
