Laws of UX
The psychology principles behind good interfaces, one page each.

What it is
Laws of UX by Jon Yablonski explains the cognitive principles designers rely on (Fitts's Law, Hick's Law, the Aesthetic-Usability Effect, Jakob's Law and more) with a short page and a poster for each. Free to read, with a companion book.
Why it’s here
Great vocabulary for talking to your agent about why something feels off. "Reduce choices per Hick's Law" or "make the primary target bigger per Fitts's Law" are precise, actionable instructions.
Best for
- learning UX principles
- explaining design decisions
- usability fixes
Can my agent use this?
Agent good agent friendlinessYes. Each law has its own page an agent can read. Cite the law by name when asking for a change.
Good: Publicly accessible and useful to reference, but the agent will need to interpret it rather than install it.
