🎨 VideoAgent Image Studio

Use when: User asks to generate, draw, create, or make any kind of image, photo, illustration, icon, logo, or artwork.

Generate images with 8 state-of-the-art AI models. This skill automatically picks the best model for the job and handles all the complexity — including Midjourney's async polling — so you can focus on the conversation.

How to Generate an Image

Step 1 — Enhance the prompt

Before calling the script, expand the user's prompt with style, lighting, and quality descriptors appropriate for the chosen model.

• Midjourney: Add cinematic lighting, ultra detailed, --v 7, --style raw
• Flux: Add masterpiece, highly detailed, sharp focus, professional photography
• Ideogram: Be explicit about text content, font style, and layout
• Recraft: Specify vector illustration, flat design, icon style

Step 2 — Run the script

node {baseDir}/tools/generate.js \
  --model <model_id> \
  --prompt "<enhanced prompt>" \
  --aspect-ratio <ratio>

All parameters:

Parameter	Default	Description
--model	flux-dev	Model ID from the table above
--prompt	(required)	The image generation prompt
--aspect-ratio	1:1	1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 21:9
--num-images	1	Number of images (1–4; Midjourney always returns 4)
--negative-prompt	—	Things to avoid (not supported by Midjourney)
--seed	—	Seed for reproducibility

Step 3 — Return the result

The script always waits and returns the final image URL(s). No polling required.

{
  "success": true,
  "model": "flux-pro",
  "imageUrl": "https://...",
  "images": ["https://..."]
}

Send the imageUrl to the user.

Midjourney Actions

After generating a 4-image grid with Midjourney, offer the user these options:

# Upscale image #2 (subtle, preserves details)
node {baseDir}/tools/generate.js \
  --model midjourney \
  --action upscale \
  --index 2 \
  --job-id <job_id>

# Create a strong variation of image #3
node {baseDir}/tools/generate.js \
  --model midjourney \
  --action variation \
  --index 3 \
  --job-id <job_id> \
  --variation-type 1

# Regenerate with same prompt
node {baseDir}/tools/generate.js \
  --model midjourney \
  --action reroll \
  --job-id <job_id>

Upscale types: 0 = Subtle (default, best for photos), 1 = Creative (best for illustrations)

Variation types: 0 = Subtle (default), 1 = Strong (dramatic changes)

Example Conversations

User: "Draw a snow leopard on a snowy mountain with cinematic lighting"

# Choose midjourney for artistic quality
node {baseDir}/tools/generate.js \
  --model midjourney \
  --prompt "a majestic snow leopard on a snowy mountain peak, cinematic lighting, dramatic atmosphere, ultra detailed --ar 16:9 --v 7" \
  --aspect-ratio 16:9

🎨 Done! Which one to upscale? (U1-U4) Or create a variant? (V1-V4)

---

User: "Use Flux to generate a perfume product poster, white background"

# Choose flux-pro for photorealistic product shots
node {baseDir}/tools/generate.js \
  --model flux-pro \
  --prompt "a luxury perfume bottle on a clean white background, professional product photography, soft shadows, 8k, highly detailed" \
  --aspect-ratio 3:4

---

User: "Show me a quick draft"

# flux-schnell for instant previews
node {baseDir}/tools/generate.js \
  --model flux-schnell \
  --prompt "..." \
  --aspect-ratio 1:1

---

User: "Make me an App icon, flat style, blue theme"

# recraft for vector/icon style
node {baseDir}/tools/generate.js \
  --model recraft \
  --prompt "a minimal flat design app icon, blue color scheme, simple geometric shapes, vector style, white background"

---

Setup

Zero API keys needed! All requests go through a hosted proxy that handles authentication server-side.

The skill works out of the box — just install and use.

Advanced: Custom proxy or token

If you want to use your own proxy or a persistent token, set these environment variables:

{
  "skills": {
    "entries": {
      "videoagent-image-studio": {
        "enabled": true,
        "env": {
          "IMAGE_STUDIO_PROXY_URL": "https://your-proxy.vercel.app",
          "IMAGE_STUDIO_TOKEN": "your_token_here"
        }
      }
    }
  }
}

Variable	Required	Description
IMAGE_STUDIO_PROXY_URL	No	Custom proxy base URL (default: https://image-gen-proxy.vercel.app)
IMAGE_STUDIO_TOKEN	No	Persistent token (auto-obtained if not set, 100 free uses per token)

To deploy your own proxy, see the videoagent-audio-studio proxy as a reference implementation. You'll need FAL_KEY and LEGNEXT_KEY as Vercel environment variables.
