ui-first-principles skillA

ui-first-principles is agent-read markdown (skill) from sd0xdev/sd0x-harness: First-principles UI/IA reasoning: turns a `<scenario>` + API field set into JTBD analysis, principle-anchored field-priority decisions, anti-pattern findings, and a bidirectional UI↔API gap report. Trigger: UI、UX、資訊架構、IA、scenario-driven UI、欄位優先級、information hierarchy. Not for: visual/CSS work (use `/frontend-design`), post-build critique (use `/critique`), or simplifying existing layouts (use `/distill`)..

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.

How to install

Latest version
mdr add sd0xdev/sd0x-harness/ui-first-principles@git:20260905.a2f4303
Exact content
mdr add sd0xdev/sd0x-harness/ui-first-principles@sha256:b118323818e5c77b

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
