DSH Image Gen

Adds gpt-image-2 generation to DeepSeek Harness by calling any third-party
OpenAI Images compatible endpoint. Fill in baseURL and API Key and use
text-to-image and image-to-image tools directly in conversation.

中文

This plugin is a rewritten, fixed fork of
dsh-image2-draw. It fixes a
load-time bug that broke the original (see "Bug fix" below).

Features

• A dedicated Image Gen card under Settings → Plugins → Plugin settings.
• Only baseURL and API Key are required; the default model is gpt-image-2.
• baseURL accepts shorthands like https://example.com/v1; the plugin appends
  /images/generations automatically.
• The edit endpoint defaults to /images/edits derived from baseURL, or can be
  set explicitly via editURL.
• image-generate (text-to-image) tool, generating 1–8 images sequentially.
• image-edit (image-to-image) tool with 1–8 PNG / JPEG / WebP reference images.
• Adaptive portrait / landscape / square sizes, plus validated custom sizes.
• Results render inline in conversation with thumbnails, lightbox zoom, and save-as.
• Images are also written to outputs/image-gen/ in the session working directory
  (auto-numbered, never overwriting existing files).
• API Key is written only to DSH credentials (default ref IMAGE_GEN_API_KEY); it is
  never echoed or stored in the settings document.
• Validates config writes, response sizes, timeouts, and reference files; 524/timeout
  is not auto-retried to avoid duplicate billing.

Install

Prerequisites

• Node.js (24 LTS recommended).
• Git.
• pnpm.

Via npx

npx --yes -p @deepseek-ai/dsh dsh plugin --profile web add github:Anyway-one/dsh-image-gen
npx --yes -p @deepseek-ai/dsh dsh web

Pin a release with github:Anyway-one/dsh-image-gen#v0.1.0.

Via pnpm + Harness source

cd <deepseek-harness>
pnpm dsh plugin --profile web add github:Anyway-one/dsh-image-gen
pnpm dsh web

Configuration

1. Open Settings → Plugins → Plugin settings and expand the Image Gen card.
2. Fill in Endpoint (baseURL), e.g. https://example.com/v1.
3. Fill in API Key (stored in credentials, default ref IMAGE_GEN_API_KEY).
4. Optionally adjust Model (default gpt-image-2), Edit endpoint, or Timeout.
5. Save, then use image-generate / image-edit in conversation.

Use Case

Development

pnpm test   # pure-function unit tests (no DSH boot required)

Layout:

• lib/index.js — Host half: image-gen settings namespace, image-generate /
  image-edit tools, /image-gen/* HTTP routes.
• lib/client.js — Browser half: settings.plugin.item config card (keyed), and
  tool.call.toolview result cards.
• cordis.patch.yml — mounts both halves (entry id image-gen).
