Use this skill to build, refactor, or review Go applications using the Uber Fx dependency injection framework. It ensures idiomatic use of Fx for lifecycle management, module-based architecture, and boilerplate reduction.
wireframe
by Magdoub
Progressive UX generation — Phase 1 generates 5 B&W wireframe options instantly (1 safe + 4 exploratory), then Phase 2 renders Clean + Polished color variants via 5 parallel Task agents (one per option). Supports wireframes-only or wireframes+visuals. Extracts optimization intent from arguments when present. Maintains persistent design context. Use when user says "wireframe", "prototype", "UX options", or "layout exploration".

prompt-optimizer
by Aznatkoiny
Optimize prompts for Claude 4.x models using Anthropic's official best practices. Use when users want to improve, refine, or create effective prompts for Claude. Triggers include requests to optimize prompts, make prompts more effective, fix underperforming prompts, create system prompts, improve instruction following, reduce verbosity, control output formatting, or enhance agentic/tool-use behaviors. Also use when users report Claude is being too verbose, not following instructions, not using tools properly, or producing generic outputs.

tdd
by fellipeutaka
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
clean-code
by fellipeutaka
Write clean, readable, and maintainable code following principles from Robert C. Martin's "Clean Code" and Object Calisthenics. Use when writing, reviewing, or refactoring code to improve naming, function design, formatting, error handling, and class structure. Includes code smell detection and refactoring guidance.

tdd-methodology-expert
by rawveg
Use proactively when you need to implement features or fix bugs using strict Test-Driven Development (TDD) methodology. This agent should be activated for any coding task that requires writing new functionality, refactoring existing code, or ensuring comprehensive test coverage, but should not be used for any design-related tasks. The agent excels at breaking down complex requirements into testable increments and maintaining high code quality through disciplined TDD cycles. Use this agent proactively or if the user mentions 'TDD', 'tdd' or 'Test Driven Development'.
