L0 regularization for neural network sparsification and intelligent sampling - used in survey calibration

Writes explanatory comments to code to improve readability for developers and AI systems. Use when documenting code or improving code comprehension.

Prepare git changes for commit by staging appropriate files, excluding agent-generated documentation, and crafting a perfect commit message. Use when ready to stage changes, preparing a commit, or need help with commit messages. NEVER commits - staging only.

Enterprise practical workflows, context engineering strategies, JIT (Just-In-Time) retrieval optimization, real-world execution examples, debugging patterns, and moai-adk workflow mastery; activates for workflow pattern learning, context optimization, debugging issue resolution, feature implementation end-to-end, and team knowledge transfer

Pixel-perfect implementation of Figma designs. When Claude needs to translate Figma designs into code with precise attention to autolayout, variables, and styles.

Deep expertise for documentation content creation. Templates, platform formatting guides, and style principles. Auto-loads for doc-writer agent.

Installs Claude Code hooks for automatic skill usage measurement.Use when setting up skill tracking infrastructure in a new project.NOT when hooks are already installed (run verify.py to check).

Mobile-first responsive design specialist for SARAISE React/TypeScript/Tailwind applications. Provides guidance on breakpoints, fluid typography, flexible layouts, touch targets, and progressive enhancement. Use when creating responsive layouts, optimizing for mobile, or ensuring cross-device compatibility.

Use when creating or developing, before writing code or implementation plans - refines rough ideas into fully-formed designs through collaborative questioning, alternative exploration, and incremental validation. Don't use during clear 'mechanical' processes

Review React 19 test quality including coverage, patterns, and React 19 API testing. Use when reviewing tests or test coverage.

This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol, (2) Systematically evaluating each dimension with specific criteria, (3) Providing actionable findings with file:line references. Triggers when users request: code analysis, design review, refactoring opportunities, code quality assessment, architecture evaluation.

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

Garantir que testes de integração usem MySQL 9.5 via Testcontainers com isolamento, migrations e secrets corretos.

Kailash Core SDK fundamentals including workflow creation, node patterns, connections, runtime execution, parameter passing, error handling, cyclic workflows, async patterns, MCP integration, and installation. Use when asking about 'workflow basics', 'core sdk', 'create workflow', 'workflow builder', 'node patterns', 'connections', 'runtime', 'parameters', 'imports', 'installation', 'getting started', 'workflow execution', 'async workflows', 'error handling', 'cyclic workflows', 'PythonCode node', 'SwitchNode', or 'MCP integration'.

Decomposes a decision-complete PRD into a clear, minimal set of user-meaningful features with explicit dependencies, producing a roadmap-ready structure without prioritization, scheduling, or implementation detail.

Method implementation finder and analyzer for Pharo Smalltalk. Provides expertise in discovering implementors across class hierarchies (search_implementors), analyzing implementation patterns, learning coding idioms from existing implementations, assessing refactoring impact (counting implementors and references), finding duplicate code for consolidation, understanding abstract method implementations (subclassResponsibility), and tracing method overrides through inheritance chains. Use when analyzing method implementations across classes, learning implementation idioms, assessing refactoring risk before changes, finding duplicate implementations for consolidation, understanding how abstract methods are implemented in concrete classes, or tracing which classes override specific methods.

Implement CQRS (Command Query Responsibility Segregation) pattern for Electron services. Use when creating service methods, separating read/write operations, or implementing reactive data streams with Observable for queries and ResultAsync for commands.

Manage Tailscale VPN, Serve, and Funnel from the CLI.

Create Buck2 tests with local resources (processes, services, databases) using LocalResourceInfo and ExternalRunnerTestInfo. Use when tests need external dependencies like databases, HTTP servers, message queues, or Unix sockets that Buck2 should manage automatically. (project)

This skill should be used when creating or refactoring Claude Code skills, guiding an interactive questionnaire, selecting an archetype (workflow/tool/domain), scaffolding from templates, and validating the result.
