What problem does it solve?

This Skill eliminates inconsistent development practices across different programming languages in OSE-style Nx monorepos, ensuring all developer agents follow the same standardized processes for tooling, version control, testing, and code quality.

Core Features & Use Cases

• Universal Nx Monorepo Guidance: Standardized commands for development, building, testing, and affected project analysis, plus best practices for app/library separation, dependency management, and avoiding circular dependencies.
• Standardized Git & Commit Workflow: Trunk-based development rules, conventional commit formatting requirements, and pre-commit automation (Husky, lint-staged, commitlint) configuration to enforce code quality.
• TDD & Environment Standards: Mandatory Red→Green→Refactor cycle for all code changes, plus step-by-step environment setup using npm run doctor and rhino-cli for toolchain convergence and environment file management.
• Use Case: A developer working on both a Go backend microservice and a Next.js frontend can follow the exact same workflow, commit standards, and testing practices without learning separate language-specific processes.

Quick Start

Use this skill to follow the standardized 6-step development workflow when building a new feature in any OSE monorepo project, including writing failing tests first, using canonical Nx commands, and adhering to conventional commit formatting.
