dsh-persona

dsh-persona is a DeepSeek Harness dual-end plugin that adds a configurable collaboration-style layer to model requests. It is built for people installing or using DSH Web, with a small settings page for choosing how the coding agent communicates.

The plugin contributes one style-oriented system prompt section at order 5, after DSH's core identity and deployment persona prefix. It shapes tone, progress reporting, validation language, and collaboration habits; DSH still owns the core prompt, tool policy, safety rules, and runtime behavior.

What It Adds

• Profile-backed dsh-persona plugin settings for the selected style and shared prompt.
• A host-side system prompt section named dsh-persona:style.
• A DSH Web settings section for style configuration while the plugin row is running.
• Two built-in style options shown in Chinese: 友好协作 and 务实直接.
• An editable common prompt block that is prepended to the selected style.

The current UI intentionally does not include a final injected-prompt preview. Users configure the shared block and chosen style separately; the host renders the final prompt section at request time.

Install

Requires Node.js 22 or newer. The compatibility baseline is DSH 0.2.0-rc.2, matching the development dependencies. The CI Web smoke test uses the same release to verify package installation and startup.

Install the plugin into the DSH Web profile from the repository:

dsh plugin --profile web add github:Diluka/dsh-persona

Restart the DSH Web profile so the Cordis patch mounts the plugin, then open the existing DSH Web GUI.

If the package is later published to npm, it can be installed by package name with the same profile target:

dsh plugin --profile web add dsh-persona

Settings Page

Use the dsh-persona component row in the DSH Plugins manager to start or stop the plugin. While the row is running, open DSH Web and go to:

Settings -> 沟通风格

Depending on the active UI language or navigation labels, the section may also appear as Communication Style.

The dedicated page currently provides:

• preset: stores the selected built-in style.
• style selector: uses a DSH-style dropdown trigger instead of the browser's native select control.
• style prompt preview: shows the complete read-only style prompt directly after the selector.
• shared: edits the common prompt block applied before the style; this editor appears at the end.
• reset action: restores the common prompt to the plugin default.

Changes are persisted through the selected profile's DSH Settings forms and apply to subsequent model requests. If an agent preset registers a complete system-prompt section, DSH intentionally omits additional sections, including this style layer; the plugin does not bypass that preset contract.

Runtime Storage

Runtime options live in the profile's dsh-persona plugin entry and are edited through DSH Settings forms. The root Config is marked volatile so edits update the prompt layer without a restart.

Composition defaults may still be supplied when mounting the plugin:

- id: dsh-persona
  name: dsh-persona
  config:
    preset: pragmatic
    shared: |-
      # Work Presentation

      - Keep the user clearly informed about ongoing actions without unnecessary detail.

Settings-page edits persist to the selected profile's Cordis composition. Clearing an override restores the value inherited from the composition.

Safety And Scope

dsh-persona is a style layer, not a control plane for agent behavior.

• It appends one additional system-prompt section; it does not replace DSH's core prompt.
• It focuses on communication style, collaboration tone, progress updates, validation summaries, and next-step wording.
• It does not implement memory, preference learning, chat history distillation, or long-term user profiling.
• It does not grant tools, change sandbox or approval policy, or widen file/network access.
• Built-in style text is read-only so installed behavior remains predictable; users customize the shared block instead.

The effective authority remains with DSH's host composition, active agent configuration, tool definitions, sandbox policy, approval policy, and model routing.

Styles

The default common prompt is a larger Codex-style output guidance block rewritten for DSH. It covers concise teammate tone, concrete progress updates, command-output summaries, validation status, and natural next steps while preserving DSH-specific wording.

The style selector adds a complete DSH-adapted Codex personality template:

• friendly / 友好协作: optimizes for team morale, supportive collaboration, pairing, onboarding, and gentle escalation.
• pragmatic / 务实直接: acts as a deeply pragmatic, effective DSH coding teammate with explicit reasoning, rigor, and concise tradeoff discussion.

The DSH component-row switch is the no-style-layer case; the plugin Config contains only the selected style and shared prompt.

Architecture Overview

This repository is a DSH plugin package, not a standalone web app.

• Host entry: registers settings-backed runtime behavior and contributes the rendered systemPrompt section.
• Prompt model: keeps shared/style rendering logic separate from DSH side effects.
• Client entry: registers a settings.section UI inside DSH Web, reads the dsh-persona entry through configForms, and writes only volatile fields.
• Profile patch: mounts the plugin into a DSH composition with optional defaults.

At runtime the host reads the volatile plugin Config, combines the common prompt block with the selected read-only style prompt, and appends the result as a style section for future model requests. The client edits profile configuration only; it does not own prompt injection.

Uninstall

Remove the plugin from the DSH Web profile:

dsh plugin --profile web remove dsh-persona

Restart the DSH Web profile after removal so the composition no longer mounts the plugin.

The style options are part of the profile's plugin configuration rather than a separate runtime settings store. Any remaining composition defaults or overrides are governed by that profile's Cordis patch.

Development And Verification

Install dependencies and run the project checks:

pnpm install --frozen-lockfile
pnpm check

Verify package contents without publishing:

pnpm pack:dry-run

Tests cover pure prompt logic, mocked Host wiring, real Cordis/system-prompt registration, volatile Config resolution, settings-form policy cleanup, literal {{...}} text, and complete-prompt precedence.

CI packs the plugin, installs that tarball into a temporary DSH Web profile using DSH 0.2.0-rc.2, starts dsh web, and fails if the server does not become reachable or exits early. This smoke test proves package installation and server startup, not browser interaction.

Useful local validation flow:

1. Install or link the plugin into a DSH Web profile.
2. Restart that DSH profile so the Cordis patch is mounted.
3. Open the existing DSH Web GUI, normally http://127.0.0.1:3080.
4. Confirm the DSH Plugins manager shows dsh-persona as running and Settings -> 沟通风格 is available.
5. Choose a style, edit shared, and verify subsequent model requests reflect the style layer.
6. Disable the dsh-persona component row in the DSH Plugins manager and confirm the settings page and style layer disappear; re-enable the row to restore them.

Do not validate this package by starting a replacement Vite server; DSH Web provides the runtime boot context for the plugin.

Current Scope

Included now:

• global DSH style prompt layer;
• profile-backed preset and shared configuration in dsh-persona;
• dedicated DSH Web settings section while the component row is running;
• DSH-style custom dropdown for choosing a style;
• editable common prompt block with reset;
• read-only friendly and pragmatic style prompts;
• Chinese style labels 友好协作 and 务实直接;
• no final injected-prompt preview in the settings UI.

Deferred until there is a concrete need:

• custom user-created styles;
• import/export of style packs;
• per-agent, per-session, or per-workspace overrides;
• prompt diff/history UI;
• memory or preference-learning features;
• richer browser E2E coverage against a running DSH profile.
