Apply the Tell Don't Ask (TDA) principle when reviewing, writing, or refactoring object-oriented code. Use this skill whenever the user asks about OOP design, mentions getters/setters, wants to review a class for encapsulation issues, asks how to move logic closer to data, or asks why code feels "procedural" despite using classes. Also trigger when the user asks to refactor code that queries an object's state before making decisions externally. This skill should kick in for any code review or design question involving data access patterns, encapsulation, or how objects should collaborate.
Elevate a working PR: hindsight review, refactor, simplify, test audit, docs, quality gates. Composes: hindsight-reviewer agent, /refactor, /simplify, /update-docs, /check-quality, /distill. Use when: PR works but could be better. "How would we do this knowing what we know now?"
Enforce low Cognitive Complexity (SonarSource) and low Cyclomatic Complexity in ALL code written or modified, in any programming language, framework, or platform. This skill MUST activate automatically whenever code is being written, generated, modified, or refactored — no explicit trigger needed. Triggers include writing any function, method, class, module, script, handler, endpoint, test, or code block. Also triggers on "low complexity", "cognitive complexity", "cyclomatic complexity", "reduce complexity", "simplify code", "too complex", "refactor for readability", "clean code", "implement", "fix bug", "add feature", "generate test", "optimize", "rewrite", "scaffold".
Remove dead code and duplication pragmatically with a 5-phase systematic approach
Python coding standards and best practices. Applicable to code generation, code review, and code refactoring scenarios.
Apply Python style guide conventions to code
Use when you need to review, improve, or refactor Java code for type design quality — including establishing clear type hierarchies, applying consistent naming conventions, eliminating primitive obsession with domain-specific value objects, leveraging generic type parameters, creating type-safe wrappers, designing fluent interfaces, ensuring precision-appropriate numeric types (BigDecimal for financial calculations), and improving type contrast through interfaces and method signature alignment.

Simplify and refine recently modified code while preserving functionality. Use when asked to "deslop", "clean up code", "simplify code", or after making changes that could benefit from refinement.
ReactLynx best practices covering dual-thread architecture and React patterns. Provides rules reference for writing, static analysis for reviewing, and auto-fix for refactoring.
Convert Phoenix app hardcoded text to use gettext with domain-based translations
Automatically generate complete Python project deliverables from natural language requirements through collaboration among four virtual roles: autonomous learning, PM, architect, and senior programmer. Supports feature expansion, project refactoring, and skill invocation. Also supports web search, knowledge integration, version control, Python 3.11+ features, UV package management, loguru logging, and project size adaptation (folder/single file). It provides support for database design and implementation (SQLite, PostgreSQL, MongoDB, vector databases, graph databases), data layer abstraction (Repository pattern), and database switching. Suitable for scenarios such as software requirement clarification, rapid prototyping, project initialization, feature expansion, and code refactoring.
A CLI tool that searches inside class and className attributes and matches against each class name individually. Use this instead of grep when searching or replacing class names.
