Perception-First Design — psychology-backed design framework. 5-layer dependency stack derives requirements from cognitive constraints before proposing solutions.
Perception-First Design (PFD) — psychology-backed design framework. Auto-activates on design, marketing, copywriting, and communication tasks. Four commands: /perception-first-design:solve (derive a solution from cognitive constraints), /perception-first-design:evaluate (corpus-backed audit of an existing artifact), /perception-first-design:analyze (descriptive cascade for hypotheticals and mechanism questions), /perception-first-design:all (run all three modes on the same input). Mode auto-detection routes bare 'pfd this' invocations to the right mode based on input shape.
