An image-generation add-on for creating single illustrations or matching sets of images. It can make transparent-background images and prepare sets for resizing, reframing, or use as platform icons.

Use it to create illustrations, image sets, transparent assets, and platform icons. It may also help make visual assets for games or other software projects.

It helps avoid creating each related image separately when you need a consistent visual style. It also handles common preparation tasks such as transparent backgrounds and icon exports.

Getting it into your agent

Security

Grade A, and why

logospell scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
