principle-subtract-before-you-add

TheOnlyFusionCube/potetos-for-everyone/skills/principle-subtract-before-you-add/SKILL.md

statechart

TheOnlyFusionCube/potetos-for-everyone/skills/statechart/SKILL.md

Draw what an app's user sees as a Mermaid statechart from a TLA+ model. States are gray if they work, red if still wrong, and green if fixed. Each bug TLC finds is a numbered path. Use for /statechart, \"show the PM the bug\", or to turn an agreed chart into a TLA+ skeleton.

claude-motion

TheOnlyFusionCube/claude-motion/SKILL.md

Make polished, continuously moving short films in code (product launch films, UI walkthroughs, animated explainers, motion-design reels and sizzles, kinetic typography posters, app and brand promos, 3D product and character scenes, data stories) and export frame-exact MP4 with an original score. Use when asked to make an animation, motion graphic, promo, teaser, launch video, demo video, explainer, showreel or animated chart, to edit one, or to critique one. Asks style, colours and length up front; offers six style presets. Built on a deterministic DOM + Three.js stage with camera, cursor, typing, hand-drawn marks and a synth, and a direction method that produces films rather than animated slideshows.

rust-rewrite-reliable

TheOnlyFusionCube/rust-rewrite-skill/.cursor/skills/rust-rewrite-reliable/SKILL.md

Use this when porting a working reference (often Python or C) into Rust on mid-tier/inferior LLMs: inject port guide + API surface, force early edit of rust/src, chunked RIIR milestone gates, frozen-test oracle, differential selfcheck, auto-resume on no-edit, multi-turn polish (esp. content-type 422), anti-cheat fingerprints; never weaken tests.
