VisionCraft Skill

VisionCraft

Generate images and videos via Agnes AI APIs. Calls PowerShell scripts in scripts/. API key is read from environment variable AGNES_API_KEY.

First time? See Prerequisites. For prompt-writing tips and parameter details, see references/.

Quick Reference

Task	Command
Text-to-Image	scripts/gen_image.ps1 -Prompt "..."
Image-to-Image	scripts/gen_image.ps1 -Prompt "..." -ImageUrl "https://..."
Text-to-Video	scripts/gen_video.ps1 -Prompt "..."
Image-to-Video	scripts/gen_video.ps1 -Prompt "..." -Image "https://..."
Multi-image Video	scripts/gen_video.ps1 -Prompt "..." -Image "https://a.png","https://b.png"
Keyframes Animation	scripts/gen_video.ps1 -Prompt "..." -Image "https://a.png","https://b.png" -Mode keyframes

Defaults: Images 2048x2048. Videos 1920x1080 @ 60fps, 241 frames (~4s).

Prerequisites

Set the API key once (persists across sessions):

[System.Environment]::SetEnvironmentVariable("AGNES_API_KEY", "sk-your-key-here", "User")

Or for the current session only:

$env:AGNES_API_KEY = "sk-your-key-here"

Verify with echo $env:AGNES_API_KEY.

How to Use This Skill

1. Identify the request

User says	Mode
"make/draw/generate a picture of..."	Text-to-Image
"edit/transform/restyle this image..." (URL provided)	Image-to-Image
"make a video / animate / generate a clip of..."	Text-to-Video
"animate this photo / make this image move" (1 image)	Image-to-Video
"blend these images into a video" (multiple images)	Multi-image Video
"smooth transition / morph from A to B" (2+ images)	Keyframes Animation

2. Refine the prompt if needed

If the request is vague, briefly suggest a richer prompt before running. For prompt structure and best practices see references/prompt-guide.md.

3. Run the script

Pass aspect ratio with -Ratio and duration with -Seconds for the simplest control. See references/parameters.md for all parameters.

# Examples:
scripts/gen_image.ps1 -Prompt "..." -Ratio 16:9
scripts/gen_video.ps1 -Prompt "..." -Ratio 9:16 -Seconds 8

4. Surface the result

The scripts print a MEDIA:<url> line on success. Always echo the URL on its own line — never bury it in a paragraph. If the platform supports inline media rendering, embed it; otherwise the URL alone is enough.

Never download the result to local disk unless the user explicitly asks.

Output Format

Image:

✅ Image generated.

MEDIA:https://platform-outputs.agnes-ai.space/images/...

Video:

🎬 Video generated (4.0s, 1920x1080).

MEDIA:https://platform-outputs.agnes-ai.space/videos/...

Errors & Troubleshooting

Error	Fix
AGNES_API_KEY not set	Set it (see Prerequisites). Restart terminal if needed.
401 Unauthorized	API key invalid or expired.
400 Bad Request	Check prompt, size format, frame count rule (8n+1, ≤441).
503 Service Unavailable	Service busy. Wait 30s, retry.
Video timeout (15 min)	Script prints the video_id — re-query later, the task is not abandoned.
