Self-contained Agent Skills collection with a shared body horror mascot. Skills are Markdown instructions. There is no runtime build step. Every skill must work when its directory is copied alone. Keep required references, scripts, templates, and licenses inside that directory. Use relative paths for bundled files. Do not depend on another skill from a personal collection.

Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,542 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

- Read brand rules before changing visual assets.

Skill boundaries
Every skill must work when its directory is copied alone. Keep required references, scripts, templates, and licenses inside that directory. Use relative paths for bundled files. Do not depend on another skill from a personal collection. Do not require a private account or personal checkout.
Use the standard name and description frontmatter fields. The name must match the containing directory. Describe the task and its trigger in plain words. Keep the main instructions short and move detailed material into references when useful.
Branding
The corrected full-arm banner is the canonical banner. Use assets/brand for current artwork. Use assets/source for high-resolution masters. Use assets/archive only for historical design reference. Preserve the four arms, two legs, and two wings. Confirm additional public slogans and decorative text with the owner.
