dsh-pure-chat

Pure chat mode for DeepSeek Harness: hide every global tool so the agent only talks. Toggle per session with /pure-chat on and /pure-chat off.

纯聊天模式插件：隐藏全部全局工具，让 agent 只对话。每条会话可用 /pure-chat on|off 开/关。

Install / 安装

dsh plugin --profile web add dsh-pure-chat
dsh web

Requires a dsh web profile on the 0.1.x line (published 0.1.0-rc.6 / 0.1.1-rc.2, or a source checkout such as 0.1.2-alpha.1). 需要 dsh 0.1.x 线的 web profile（npm 的 rc 版本或源码版 alpha 均可）。

Usage / 用法

/pure-chat — toggle for the current session:

• /pure-chat or /pure-chat on — hide all global tools (bash/fs/web/…); the agent can only receive and reply with text.
• /pure-chat off — restore the session's tools.

How it works / 原理

On enable, the plugin applies three layers to the receiving agent: tools.restrict({ allow: [] }) hides inherited global tools from the model's view, a tools.guard denies any tool execution that still happens (Tools are disabled: pure chat mode is active.), and a systemPrompt.section instructs the model not to call tools. Disabling (/pure-chat off) disposes all three. The /pure-chat command itself is registered against the commands service, declared via the loader entry's inject: [commands].

启用时对当前 agent 施加三层保护：tools.restrict({ allow: [] }) 从模型视野隐藏继承的全局工具；tools.guard 对仍在发生的调用一律拒绝（返回 Tools are disabled: pure chat mode is active.）；systemPrompt.section 提示模型不要调用工具。/pure-chat off 会一并回收这三层。命令注册通过 loader entry 的 inject: [commands] 声明 commands 服务。

Notes / 说明

• Tools are restricted per agent/session, not globally; new sessions start with tools enabled — opt in where you want pure chat. 工具限制是按会话的；新会话默认有工具，需要时再 /pure-chat on。
