/fassal

fassal · verb · “to design”
Writes a product's UX principles, so agents make interface decisions the way you would.

Without written UX principles, every agent makes interface decisions its own way.

Use it when a product with a UI has no UX principles yet, or they need refining. You get a UX_PRINCIPLES.md that /wettaq and the UI designer follow when they make interface decisions. It needs your answers to the few product questions the repository cannot answer.

Agent instructions

The agent follows the instructions below, from commands/fassal.md. Its one-line description is: Generate or refine the product's UX principles document.

Full agent instructions

Load the ux-principles skill and run it for the active repository. Treat $ARGUMENTS as optional product context or a requested area of refinement, not as a substitute for repository inspection and adaptive discovery.

Create or maintain UX_PRINCIPLES.md only. Do not implement product changes or modify implementation commands, execution workflows, or agents.

Old name: /ux.principles, which still works for one release.
