Performs dynamic, reflective problem-solving through iterative thought chains. Use for complex planning requiring revision, branching, backtracking, or hypothesis verification. Ideal for multi-step analysis where context maintenance is required or the full scope isn't initially clear.

Spring Boot 3.x framework patterns: constructor-based DI, Spring Data JPA, REST controllers with RFC 7807 error handling, Actuator observability, and slice testing. Use when building or maintaining Spring Boot microservices. Pair with java-idioms.

SQL coding standards: CTEs, explicit JOINs, index optimization, query execution plan analysis, transaction locking, and zero-downtime migration patterns. Use when writing complex queries, analyzing performance, or drafting database migrations.
Skill Claude CodeCodex
Write, review, validate, or parse structured specification documents — PRDs, SDDs (design docs), implementation plans, TSDs (technical specs), BDD specs, and ADRs (architecture decision records) — using the Structured Spec standard (YAML frontmatter + Markdown narrative + HTML-comment annotations for…
Skill Claude CodeCodex
SBOM generation, CVE scanning, supply chain attack detection, license compliance, dependency pinning, and artifact verification.
Skill Claude CodeCodex
Swift idioms and best practices: value types, Optionals hygiene, protocol-oriented design, async/await and Actor concurrency, and XCTest. Use when writing, refactoring, or reviewing Swift iOS, macOS, or server-side code.
Skill Claude CodeCodex
Implementation examples for the three testability rules (I/O isolation, pure logic, dependency direction) across Go, TypeScript, Python, Rust, and Dart. Loaded by reference from architectural-pattern.md — not triggered by file patterns.
Skill Claude CodeCodex
Detailed testing reference material: test doubles strategy, integration test infrastructure (Testcontainers, Firebase emulator), naming conventions per language, test organization patterns. Load when writing tests or setting up test infrastructure. The core mandates (TDD, AAA, pyramid) are in the testing-strategy rule…
Skill Claude CodeCodex
TypeScript strict typing: type narrowing, discriminated unions, Zod runtime validation, generic utility types, and Vitest testing. Use when writing or refactoring TypeScript across frontend, backend, or full-stack projects.
