dsh-prompt-polish

English | 中文

A DeepSeek Harness (DSH) plugin that adds a ✨ sparkle button to the web composer's tool row. Click it, pick a rewrite style, and the already-connected LLM rewrites your draft prompt to be more professional and easier for an AI to understand — then replaces the draft so you can review before sending.

• Icon-only button — a sparkle glyph in the composer tool row; no text, tooltip gives the full description.
• Four rewrite styles — balanced / concise / detailed / code-oriented.
• Multi-language UI — menu copy follows your browser language (zh, en, ja, ko, fr, de, es, pt, ru, it, tr, vi; falls back to English).
• Uses your connected model — resolves the current default agent model (agentDefaultModel), or an explicit provider/model from config.

Requirements

• DeepSeek Harness (@deepseek-ai/dsh) web profile running, with a model adapter configured (e.g. the DeepSeek provider with an API key in Settings).

Install

# from a checkout of this repository (or the directory containing it)
dsh plugin --profile web add ./dsh-prompt-polish

Then restart dsh web so the profile picks up the new bundle:

dsh web

Open the web UI, type a draft, and click the sparkle button in the composer tool row.

Configuration

The plugin accepts optional config in the profile's cordis.patch.yml (user layer, applied after the bundle layer):

- id: prompt-polish
  config:
    provider: deepseek-official   # explicit route (optional)
    model: deepseek-v4-flash      # must be paired with provider
    style: balanced               # default rewrite style: balanced | concise | detailed | code
    maxTokens: 2048               # output cap for the rewrite call
    # system: '...'               # custom rewrite instruction (replaces the built-in per-style prompts)

Without provider/model, the plugin uses agentDefaultModel.currentSelection() — the same default model the session uses.

How it works

Half	File	Role
Host	lib/index.js	Registers POST /prompt-polish on the web server; streams one LLM rewrite via ctx.llm
Browser	lib/client.js	Registers the sparkle button into conversation.input.right; opens a style menu; posts the draft and replaces it with the polished text

The bundle's package.json declares both faces of the dual-face plugin:

• dsh.bundle — the profile patch layer (cordis.patch.yml) that inserts the prompt-polish loader row.
• dsh.client — the web boot row; client-modules serves lib/client.js at /plugins/dsh-prompt-polish/client.js.

Development

Edit lib/index.js (host) and lib/client.js (browser). The browser bundle is a hand-built closure-factory artifact (window.__ModuleLoader__.load({ id, factory })) — keep externals limited to the platform modules (react, @deepseek-ai/dsh-client-ui-primitives) and inline everything else, matching the loader's module-table rules.

Verify on a scratch port before touching the live profile:

dsh web --port 3099
curl -s http://127.0.0.1:3099/plugins/dsh-prompt-polish/client.js | head
curl -s -X POST http://127.0.0.1:3099/prompt-polish \
  -H 'content-type: application/json' \
  -d '{"text":"read a.csv and sort by b","style":"code"}'
