What problem does it solve? Design teams often reduce Brazilian identity to surface decoration like colors, motifs, and famous names. This Skill turns Brazilian design, architecture, and vernacular visual culture into concrete, testable interface rules grounded in the Cobogó OKF knowledge corpus. ## Core Features & Use Cases - Corpus-first research: Query the existing Cobogó knowledge bundle with okf-parser (check, inventory, graph) before searching externally for new references. - Rule derivation workflow: Separate observed phenomena from derived interface rules, then run surface-swap and accessibility tests before promoting anything to canon. - Consumer validation: Test rules against real interfaces like Astronauta and O Vigia to ensure family resemblance without uniform skins. - Use Case: When designing a dashboard that needs hierarchy without boxes, research cobogó and spatial-permeability references, derive a composition rule, validate accessibility, and persist the rule as a canon-rule concept in the OKF bundle. ## Quick Start Ask the agent to derive an interface rule from Brazilian design references for your current layout problem using the Cobogó corpus.
