Apply Martin Fowler-inspired refactoring rules to improve existing code structure while preserving observable behavior. Covers code smells, small safe refactoring steps, test-backed cleanup, and separating refactoring from feature changes.

This skill applies Refactoring.Guru-inspired rules for diagnosing code smells and selecting appropriate refactoring techniques. It helps preserve behavior while avoiding uncontrolled redesign. Before making design or code decisions, read the mini rules first. Use the full guide only as a deeper reference when needed. It ensures targeted cleanup without over-engineering.

This skill allows delegating self-contained coding tasks to assistants like Codex or Claude Code via non-interactive background processes. It supports feature development, code review, and refactoring. Use OpenSquilla's exec_command and process tools to manage sessions, poll output, and send inputs without blocking the main workflow. Ideal for tasks requiring substantial file exploration.

A set of behavioral guidelines derived from Andrej Karpathy's observations to help users writing, reviewing, or refactoring code with Large Language Models (LLMs). It guides developers to avoid overcomplication, make surgical changes, explicitly surface assumptions, and define verifiable success criteria, promoting clean, simple, and robust code development.

This skill provides a comprehensive guide for optimizing Angular applications. It covers performance bottlenecks, bundle size reduction, and rendering efficiency. Use it when writing, reviewing, or refactoring Angular code to ensure optimal speed and load times.

This skill provides expertise in proven backend architectural patterns, including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design (DDD). It guides users in building highly maintainable, testable, and scalable systems. Use it when designing new services, refactoring complex monoliths, establishing team standards, or planning microservice decompositions. It emphasizes defining clear boundaries and handling complex, durable workflows.

This skill performs a comprehensive architecture audit on codebases by mapping module dependencies and checking layering integrity. It identifies structural decay using principles from classic engineering books. The tool generates Mermaid dependency graphs, assesses testability seams, and applies Conway's Law checks to ensure architectural health. It is suitable for developers needing to understand codebase structure, review folder organization, or detect circular imports before refactoring.

Identifies, classifies, and prioritizes maintainability problems to help teams build a refactoring roadmap, drawing on twelve classic engineering books.

This skill guides users to resume interrupted work and reconstruct prior decisions during code refactoring. It involves locating task ledgers, reading relevant files, and separating verified work from unfinished tasks. Users must validate volatile facts against the current codebase and resolve conflicting notes. It provides a procedure for stating the next verifiable action without installing external tools or memory systems.

Refactor tangled or hard-to-maintain code into clean, testable modules using SOLID principles. Assess code smells, plan incremental changes, and verify with tests for safer long-term maintenance.

This skill helps identify technical debt in software projects by analyzing code and change history. It estimates impact, prioritizes improvements, and creates actionable remediation plans. Focuses on code quality, architecture, testing, and infrastructure issues to reduce maintenance costs and improve development velocity.

This expert analyzes and refactors existing codebases to enhance quality, maintainability, and performance. It specializes in applying clean code principles, SOLID design patterns, and modern software engineering best practices. Use it to clean up technical debt, simplify complex modules, or prepare a codebase for new feature development.
