The Essentialist. Ruthlessly simplifying code, removing dead features, and enforcing Clean Architecture.
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.
Guidance on Python code style optimization and Pythonic idioms; Based on the complete content of *One Python Craftsman* and the "Friendly Python" concept, covering variable naming, control flow, data types, container types, function design, exception handling, decorators, file operations, and SOLID principles; Providing user-friendly and maintainer-friendly design patterns, review checklists, and over 140 practical templates
State-machine driven orchestrator for structured software development. Invoke when user wants to develop features, fix bugs, or refactor code. Triggers: 'build a feature', 'fix this bug', 'implement', 'develop', 'refactor'.
Apply systematic code refactoring with small steps, clear boundaries, and proven techniques. Use when improving existing code, reducing technical debt, cleaning up legacy code, or when user mentions refactoring, code cleanup, or code improvement.
Use this skill whenever you are implementing a feature using TDD.
Refactors code following Ousterhout's design principles. Analyzes complexity, creates prioritized refactoring plan, and executes with safety-first approach. Optimized for Vite/React, Tauri/Rust, Zustand stack.
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?"
Evaluate and improve code modularization using the Balanced Coupling Model. Analyzes coupling strength, connascence types, and distance to identify refactoring opportunities and architectural improvements. Use when reviewing code architecture, refactoring modules, or designing new systems.
Systematic code refactoring following Martin Fowler's catalog. Methodologies: characterization tests, Red-Green-Refactor, incremental transformation. Capabilities: SOLID compliance, DRY cleanup, code smell detection, complexity reduction, legacy modernization, design patterns, functional programming patterns. Actions: refactor, extract, inline, rename, move, simplify code. Keywords: refactor, SOLID, DRY, code smell, complexity, extract method, inline, rename, move, clean code, technical debt, legacy code, design pattern, characterization test, Red-Green-Refactor, functional programming, higher-order function, immutability, pure function, composition, currying, side effects. Use when: improving code quality, reducing technical debt, applying SOLID principles, fixing DRY violations, removing code smells, modernizing legacy code, applying design patterns.
Review changes for test gaps, simplification, naming consistency, reuse opportunities, and TODO quality
Architecture optimization team skill. Analyzes codebase architecture, designs refactoring plans, implements changes, validates improvements, and reviews code quality via CSV wave pipeline with interactive review-fix cycles.
