Model software around the business domain using bounded contexts, aggregates, and ubiquitous language, with scoring and diagnostic tools for evaluating domain model quality.

wondelai Bundle

Apply meta-principles of software craftsmanship: DRY, orthogonality, tracer bullets, and design by contract to build systems that are easy to change, understand, and trust.

wondelai Bundle

Apply named refactoring transformations to improve code structure without changing behavior, guided by code smells and safe transformation sequences.

wondelai Bundle

Safely change and test untested codebases using techniques from Feathers' 'Working Effectively with Legacy Code': seams, characterization tests, sprout/wrap, and dependency-breaking.

jeffallan Bundle

Writes, debugs, and refactors JavaScript code using modern ES2023+ features, async/await patterns, ESM module systems, and Node.js APIs.

jeffallan Bundle

Designs incremental migration strategies, identifies service boundaries, produces dependency maps and migration roadmaps, and generates API facade designs for aging codebases.

alirezarezvani Skill

Enforces a strict efficiency ladder—YAGNI, reuse, stdlib, native platform, existing deps—before writing any new code, preventing over-engineering and unnecessary dependencies.

antigravity Bundle

Compares two code versions for semantic equivalence by tracing both side-by-side, identifying divergences, and producing a structured verdict.

antigravity Bundle

Identifies, classifies, and prioritizes tech debt to build a refactoring roadmap, drawing on twelve classic engineering books.

antigravity Skill

Provides patterns and strategies for migrating imperative TypeScript code to fp-ts functional programming patterns, covering error handling, null checks, callbacks, dependency injection, and loops.

thedotmack Skill

Maps a codebase into feature-grouped flowcharts, identifies duplicated concerns across features, and proposes a unified architecture with handoff prompts for refactoring.

ecnu-icalk Skill

Scans classes in a specified package using Spring's ResourcePatternResolver and filters out abstract classes, interfaces, and classes without public constructors.

ecnu-icalk Skill

Migrates C# code from the legacy Nest library (1.x) to version 7.17.5, covering API changes, query syntax refactoring, source filtering, aggregations, and MultiSearch logic.

tinh2 Skill

Scans a codebase for Martin Fowler's catalog of code smells, reporting each with location, severity, and refactoring recommendations, and ranks files to build a prioritized refactoring queue.

tinh2 Skill

Applies the same change across multiple repositories in parallel using git worktrees, tests, and pull requests.

pranavnagrecha Bundle

Migrate LWC components from fragile querySelector lookups to typed lwc:ref handles, with guidance on lifecycle timing, shadow boundaries, and iterator limitations.
