Refactorització
Reestructuració i optimització del codi
clean-code
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.
Architecture Review
itzikiusa
A focused, single-lens review of a change's design and structure — not its defects. Judges separation of concerns and SOLID, coupling and cohesion, module/layer boundaries and dependency direction, whether the right abstraction is present (and the wrong/early one is absent), files and functions that have grown too large or do too much, leaky abstractions, intent-hiding names, duplication that wants to be a shared unit, and whether the change fits how this codebase is already built. Every finding cites file/module:line, a severity, the future cost it imposes, and a concrete refactor direction. Constructive and pragmatic — flags structure that will cost future change, never taste.
implementing-communitytoolkit-mvvm
christian289
"Implements MVVM pattern using CommunityToolkit.Mvvm with ObservableProperty attributes. Use when building ViewModels with source generators or implementing commands in WPF."
compiler-performance
marius-townhouse
Use when build times are slow. Use when optimizing TypeScript projects. Use when configuring project references. Use when dealing with large codebases. Use when improving IDE responsiveness.
5d-reflect
tapania
"Extract learning from completed work to improve future cycles. Use when: (1) After VERIFY phase shows feature complete, (2) End of development iteration, (3) User asks for 'retrospective,' 'lessons learned,' or 'what went well/wrong,' (4) Before starting next major feature. This phase prevents repeating mistakes and compounds learning."
module-augmentation
marius-townhouse
Use when extending third-party types. Use when adding properties to existing interfaces. Use when plugins extend core types. Use when declaration merging is needed. Use when augmenting global types.
markdown-formatter
maxvaega
Format and clean up markdown documents following best practices
test-driven-development
julianromli
Use when implementing any feature or bugfix, before writing implementation code
performance-profiling
xenitV1
Performance profiling principles. Measurement, analysis, and optimization techniques.
product-photography
sanky369
Generate professional product photography and hero shots using AI. Use when creating product images for e-commerce, landing pages, or marketing materials.
tdd-workflow
xenitV1
Test-Driven Development workflow principles. RED-GREEN-REFACTOR cycle.
simplify
jankneumann
Review changed code for reuse, quality, and efficiency, then apply low-risk simplifications that preserve behavior exactly. Requires a coverage gate and characterization tests when the surface is unpinned; dual-run verification proves the suite stays green without changing test expectations.
applying-solid-principles
BenjaminG
This skill should be used when implementing code that requires SOLID principles and clean code practices. It provides detailed guidance on Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion principles with comparison examples in TypeScript.
ask-questions-if-underspecified
M4n5ter
Clarify requirements before implementing. Do not use automatically, only when invoked explicitly.
deprecation-and-migration
jankneumann
Manage the lifecycle of removing systems, APIs, features, and dependencies. Use when sunsetting a capability, replacing one implementation with another, consolidating duplicates, killing zombie code, or planning the eventual deprecation of something new at design time. Covers the Churn Rule (owners fund migration cost), the strangler / adapter / feature-flag patterns, the five-question decision matrix, advisory-vs-compulsory deprecation, and how to drive it through an OpenSpec change.
code-polisher
k1lgor
Use this when the user asks to refactor, clean up, optimize, or improve code quality.
dough-post-change-refactor
terryyin
Refactors concepts implicated by the current uncommitted change before commit. Includes untouched representations and orchestration needed for coherence, stops before unapproved cross-subsystem refactoring or disputed plan behavior, and tests only after edits. Use after a slice, for post-change refactoring, or to clean up the current change.
anti-ai-writing
cdeistopened
Transform AI-assisted drafts into authentic, human-sounding content. This skill provides patterns to detect and eliminate AI tells, frameworks for natural writing, and techniques for creating prose that reads as genuinely human. Use when reviewing any AI-generated content or when writing content that must not appear AI-assisted.
Clean Build Artifacts
Sounder25
Removes ignored build artifacts (bin, obj, node_modules) to reclaim space and fix ghost build errors. Safely respects .gitignore.
Context Window Pruner
Sounder25
Optimize information density by filtering workspace files based on relevance to the current task. Excludes high-noise files (lockfiles, assets) and prioritizes source code matching semantic queries.
prompt-optimizer
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.
refactordjango
agusabas
Refactor Django/Python code to improve maintainability, readability, and adherence to best practices. Transforms fat views into Clean Architecture with Use Cases and Services. Applies SOLID principles, Clean Code patterns, Python 3.12+ features like type parameter syntax and @override decorator, Django 5+ patterns like GeneratedField and async views. Fixes N+1 queries, extracts business logic from views, separates Read/Write serializers, and converts exception-based error handling to explicit return values. Use when refactoring Django code, applying Clean Architecture, or modernizing legacy Django projects.
technical-architecture-council
antonioc-cl
Expert software architecture council with 6 advisors (Fowler, Beck, Uncle Bob, Newman, Hightower, Kim) for code design, architecture patterns, infrastructure, and development practices.
code-simplify
HJewkes
Simplify and refine code for clarity, consistency, and maintainability. Use after writing or modifying code to clean it up while preserving all functionality.
