What it does
When you ask for transparent artwork such as ornaments, sprites, emblems or UI graphics, the agent follows a structured workflow: it writes a detailed image prompt, asks the built-in Codex image tool to generate the picture, and then runs a small Python helper to confirm the PNG really has transparent areas. It also keeps the original file, records the prompt and file hashes, and can copy assets into a project's folders. The skill itself does not create images; it directs the agent to the image tool and checks the results.
Great for
- Game developers who need transparent PNG sprites, corners or crests for interface layouts
- Designers producing isolated UI graphics that must stack cleanly over backgrounds
- Teams that want a documented record of how each generated asset was made and verified
Skip it if
- Anyone needing a model choice or a specific model version: the built-in tool exposes no model selector, so the skill cannot guarantee which model ran.
- Environments without the built-in Codex image generation tool: the skill says to stop and explain the blocker rather than switch providers.
- Users who need vector or hand-drawn SVG output: the skill explicitly avoids substituting vector assets.
Try asking
- “Generate a transparent PNG corner ornament for my fantasy game menu and verify its alpha channel.”
- “Create a centered crest emblem with transparent holes for my UI, and save the prompt and hashes alongside it.”
- “Edit this existing sprite with the built-in image tool, keeping the original as a reference, then check transparency.”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Describe the silhouette, padding and transparent openings explicitly in your request so the generated image needs fewer edits.
- Ask for one asset per request when you need separate usable files; the skill avoids sprite sheets unless you ask.
- Always visually check enclosed gaps on a checkerboard or your real background, since the helper only measures alpha values.
