Loopyard's spacing/grouping + gutter rules for ANY UI (sidebars, chat cards, option lists, panels, forms). Load this BEFORE writing Tailwind spacing/margin/gap classes on a multi-item layout — it's the fix for the recurring mistake where within-group and between-group spacing look the same, so nothing reads as a group.
Run a setup eval — launch a project, monitor the agent, record results
Diagnose LiveView UI flashes, re-render loops, and state/view mismatches by introspecting the running app via mix loopyard.rpc. Use when the user reports anything that "flashes", "flickers", "keeps changing", "blinks", "keeps updating", or when an assign is suspected of being overwritten. RPC-based — no browser needed.
