System design patterns for scalability, reliability, and performance. Use when: (1) designing distributed systems, (2) planning for scale, (3) making architecture decisions, (4) evaluating trade-offs.

REST APIs, GraphQL, FastAPI, data service design, and integration

Verify constructive alignment between objectives, activities, and assessments; validate instructional design quality and learning science principles. Use when reviewing curriculum quality, checking alignment, or validating pedagogical soundness. Activates on "review alignment", "check pedagogy", "validate curriculum", or "quality review".

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

Vision and multimodal capabilities for Claude including image analysis, PDF processing, and document understanding. Activate for image input, base64 encoding, multiple images, and visual analysis.

Comprehensive repository initialization and scaffolding for new projects. Use when setting up a new repository from scratch with git, GitHub, CI/CD workflows, branch protection, validation checks (format, lint, type-check, tests, builds), git hooks (husky/lefthook), GitHub Actions for PR and main branch validation, automated versioning and tagging, and project-specific release workflows. Ideal for solo developers who want production-ready repository setup including (1) Git initialization with main branch, (2) GitHub repository creation and configuration, (3) Branch protection rules, (4) PR workflow with squash merging and auto-delete branches, (5) Comprehensive validation checks, (6) Git hooks for pre-commit and pre-push validation, (7) GitHub Actions CI/CD pipelines, (8) Automated releases with GitHub Releases integration.

Enable HTTPS for local development with trusted SSL certificates. Use when developers need to test SSL/TLS features, work with third-party APIs requiring HTTPS, or simulate production environments. Supports mkcert, OpenSSL, and automatic certificate trust configuration for macOS, Linux, and Windows.

MUST be loaded before working with any Skill. Covers creating, building, reviewing, assessing, checking, auditing, evaluating, updating, modifying, and improving skills. Invoke PROACTIVELY before writing or changing any SKILL.md file. Provides structure, workflows, and validation for skill development. Supports both personal skills and standalone distributable skills (GitHub repos). (user)

Generate React components following DevPortfolio patterns with automatic scaffolding. Use when asked to create components, generate UI elements, scaffold new features, or create React components. Generates TypeScript components with proper structure, translations, tests, and animations.

Playwright best practices including selectors, wait strategies, accessibility testing, responsive design, and flaky-test prevention. Use when writing or improving Playwright E2E tests.

Assess technical, financial, operational, and organizational feasibility of learning projects including resource requirements, budget, timeline, and risk analysis. Use when evaluating project viability before committing resources. Activates on "feasibility study", "project viability", "resource planning", or "can we do this".

Analyze and optimize grammar learning progression, identify dependencies between concepts, and generate structured learning paths. Use for curriculum planning, content organization, and grammar exercise generation.

Especialista em design de APIs RESTful e GraphQL, documentação e boas práticas de arquitetura de APIs

Guide for creating effective skills. Use this skill when you want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Technical specification writing for implementation details. Use when documenting how to build a solution (post-decision), API contracts, schemas, and system design. Complements RFC skill which handles decision-making.
