DeepSeek Harness settings plugin for the tool policy of agent presets. It adds an Agent Manager settings section; it does not manage model providers or model metadata.

Shows only the tools explicitly declared by the selected preset with agentTool.label.
Lets a user toggle static disabled: true / disabled: false rows in a locally authored preset.
Keeps shipped and other system-owned presets read-only, with a copy-to-user-preset path before editing.
Shows whether a declared row is host-controlled, not mounted, available, unavailable, or stale.
Makes clear that a policy change applies to later sessions; an existing session keeps the composition it started with.

The plugin delegates roster discovery, validation, locking, atomic writes, and runtime status to the Host's ctx.agentPresets service. The client retains only the currently selected preset in local browser storage.

Compatibility

This plugin requires a DeepSeek Harness build whose @deepseek-ai/dsh-agent-presets service provides inspectTools() and setToolEnabled(). It is packaged as a normal DSH plugin bundle and contributes one settings section through the public client injection points.

Declaring a tool

Preset authors opt a model-facing row into this Manager explicitly:

- id: persistent-bash
  name: '@deepseek-ai/dsh-tool-bash-persistent'
  disabled: false
  agentTool:
    label: Persistent Bash

Rows without agentTool.label stay outside the interface, even if their package happens to provide a tool. Conditional values such as disabled: !!js process.platform === 'win32' remain visible as Host-controlled but are not browser-switchable.
