Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Use when assessing team resilience, planning for developer departures, calculating bus/truck factor, identifying knowledge silos, or evaluating organizational risk - maps code ownership from git history and identifies single points of failure using research-backed thresholds (>80% ownership = silo)

Vue 3 and Nuxt 3 development with TDD workflow, QA gates, and E2E test generation. Enforces unit testing before implementation, generates Playwright E2E tests from Gherkin acceptance criteria, and produces JSON reports.

Clerk and Supabase integration patterns for user sync, JWT authentication, and RLS policies. Use when integrating Clerk authentication with Supabase, syncing user data between platforms, configuring RLS with Clerk JWT tokens, setting up webhooks for user events, implementing secure database access with Clerk identity, or when user mentions Clerk Supabase sync, user synchronization, JWT RLS, authentication webhooks, or database user management.

Comprehensive guide to Learning Path patterns for the Plataforma B2B de treinamento técnico corporativo educational platform. This skill covers the conceptual difference between Study Areas (courses) and Proposed Paths (sequences of courses), data modeling, UI/UX patterns, and implementation guidelines. Learn how to structure Learning Paths correctly: a Proposed Path is NOT a container of loose flashcards, but a curated sequence of Study Areas (courses). Each path references existing courses with metadata like order, availability status, and estimated hours. Real-world examples are taken from the Hub MVP implementation (US-044), including caminhoExemploData.js, HubView.jsx, and LearningPathView.jsx. The skill demonstrates the reference pattern used for "Desenvolvedor Backend" path that sequences Bash, Linux, Docker, and DevOps courses. Key topics include data schema design (cursos array with ordem, areaId, disponivel flags), computed properties (getters for statistics), navigation patterns (path -> course -> lesson), availability states (disponivel: true/false with badges), and how to add new paths without duplicating course data. This skill is essential for implementing new Learning Paths, maintaining the Hub MVP pattern, scaling to multiple paths, and ensuring UI/UX consistency across the educational platform. Includes the correct mental model for Course vs Path separation.
