Coordinate parallel code reviews across multiple quality dimensions with deduplication and severity calibration. \n \n Allocates reviews across five dimensions (Security, Performance, Architecture, Testing, Accessibility) with recommended combinations for different code change types \n Deduplicates findings from multiple reviewers using merge rules based on file location and issue type, with conflict resolution for severity ratings \n Provides severity calibration criteria (Critical, High, Mediu

Comprehensive testing framework for shell scripts using Bats with patterns, fixtures, and CI/CD integration. \n \n Covers core Bats concepts including test syntax, assertion patterns for exit codes and output, and setup/teardown lifecycle management \n Provides mocking and stubbing strategies for external commands, functions, and environment variables to isolate units under test \n Includes fixture management patterns, error condition testing, and shell compatibility validation across bash, sh,

Implement proven backend architecture patterns for maintainable, testable, and scalable systems. \n \n Covers three core patterns: Clean Architecture (layered dependency inward), Hexagonal Architecture (ports and adapters), and Domain-Driven Design (bounded contexts, aggregates, value objects) \n Includes complete directory structures, code examples, and implementation patterns for Python backends using FastAPI, asyncpg, and similar frameworks \n Demonstrates practical separation of concerns: do
