When touching existing code and wanting to leave it better. Use when the user says "clean this up while I'm here," "should I fix this," "tech debt," "while I'm in this file," or "incremental improvement." For full refactoring, see solid or…
When organizing project structure, establishing patterns, or reducing configuration overhead. Use when the user says "how should I organize this," "what's the convention," "too much config," "project structure," "naming pattern," or "standardize this." For…
Analyze a codebase to detect its language, framework, conventions, and CI gates. Run this on first use in a project to generate stack context that all coding principle skills reference. Use when the user says "detect stack," "analyze this project," or "what's…
When writing or reviewing code to eliminate duplicated knowledge and business logic. Use when the user says "this is duplicated," "we have this in two places," "single source of truth," "DRY this up," or "shotgun surgery." For premature abstraction concerns,…
When writing or reviewing code to reduce complexity and improve readability. Use when the user says "simplify this," "too complex," "hard to read," "clean up," "what does this do," or "can't follow this code." For over-engineering concerns, see yagni. For…
When reviewing code for excessive coupling and deep object chains. Use when the user says "too coupled," "train wreck," "chained calls," "feature envy," "mocking is painful," or "this reaches too deep." For broader structural coupling, see solid.
When structuring code into layers and modules with clear boundaries. Use when the user says "this function does too much," "fat controller," "mixed concerns," "where should this logic go," or "separate the layers." For interface-level design, see solid. For…
When designing module boundaries, interfaces, or class hierarchies for maintainable architecture. Use when the user says "how should I structure this," "too coupled," "hard to test," "dependency injection," "single responsibility," or "interface design." For…
