fitts-law skillA

fitts-law is agent-read markdown (skill) from the-artificer-of-ciphers-llc/skills-from-the-artificer: Apply Fitts's Law whenever someone is designing or critiquing a user interface—button placement, click targets, menu design, touch UI, navigation, or any interactive element. Trigger on phrases like "where should I put this button?", "users are missing this control", "the click target feels small", "how should I design this menu?", or any UX/UI discussion about the effort required to interact with an element. Fitts's Law is one of the oldest and most empirically reliable principles in human-comp.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
