Software Development Skills

Create complete REST API CRUD operations using API Platform 4 with DDD and CQRS patterns.

Pragmatic test automation workflow. Detects the project's test framework, generates API tests (status codes, response structure) and E2E tests (user workflows, semantic locators) for existing features, runs them, and produces a coverage summary. Covers happy path + critical errors using standard framework APIs. Ship it and iterate. Use when 'qa automate', 'generate tests quickly', 'quick test generation', 'qa tests', 'automate qa' is mentioned.

Implement production-grade caching with cache keys/TTLs/consistency classes per query, SWR (stale-while-revalidate), explicit invalidation, HTTP cache headers, and…

Enforce code organization principles - "Directory X contains ONLY class type X", DDD naming patterns, PHP best practices, type safety, and SOLID principles. Use when reviewing code structure, placing classes, or ensuring proper organization.

Maintain and improve code quality using PHPInsights without decreasing quality thresholds. Use when PHPInsights fails, cyclomatic complexity is too high, code quality drops, or when refactoring for better maintainability. Always maintains 94% complexity and 100% quality/architecture/style scores.

Diagnose and fix Deptrac architectural violations automatically. Use when Deptrac reports dependency violations, layers are incorrectly coupled, or when refactoring code to respect hexagonal architecture boundaries. Never modifies deptrac.yaml - always fixes the code to match the architecture.

Guide for contributing to the OpenAPI layer using processor pattern, complexity management, and functional programming. Use when adding endpoint factories, processors, parameter descriptions, reducing cyclomatic complexity, or fixing OpenAPI validation errors. Covers architecture patterns from user-service repository.

Create comprehensive project documentation from scratch. Use when setting up INITIAL documentation for a new project or building a complete documentation suite. NOT for updating existing docs (use documentation-sync instead). Covers project analysis, documentation structure, templates, and verification.

Design and implement DDD patterns (entities, value objects, aggregates, CQRS). Use when creating new domain objects, implementing bounded contexts, designing repository interfaces, or learning proper layer separation. For fixing existing Deptrac violations, use the deptrac-fixer skill instead.

Configure verbosity levels, live log streaming, JSONL file export, model I/O logging, and audit trails for monitoring agent execution.
