# DSH Prompt Optimization

DeepSeek Harness web plugin that adds a prompt optimization action beside the composer. The optimized draft replaces the current input and can be restored with one click. A dedicated optimizer model can be selected in **Settings → Prompt Optimization**.

## Features

- **One-click optimization** — sends the current draft through a one-off host-side model request and writes the result back to the composer.
- **Undo** — restores the original draft for the current session.
- **Default model** — uses the current session model when no optimizer model is configured, otherwise falls back to the deployment default.
- **Prompt Optimization settings** — lists the same providers and models available in **Settings → Models**.

## Install

```sh
dsh plugin --profile web add github:du-u-uck/DSH-Prompt-Optimization
```

Restart DSH Web after installation.

## Local development

```powershell
pnpm install
pnpm build
powershell -NoProfile -File scripts/install-web.ps1
```

## Architecture

- Host half: `lib/index.js`
- Browser client: `lib/client.js`
- Bundle manifest: `cordis.patch.yml`

## Limits

- Replacing the draft loses reference chips such as `@file`; undo restores the saved text draft.
- Optimization rewrites wording but does not add requirements that were not present in the draft.
- Requests are capped at 256 KB input, 4096 output tokens, and a 120-second timeout.
