Can I leave placeholders or TODOs in my code?

No, this skill strictly forbids placeholders and TODOs, requiring all functionality to be fully implemented and production-ready immediately.

Does this skill support different programming languages?

Yes, it provides standardized patterns and examples for multiple languages including TypeScript, Swift, and Go to ensure cross-stack consistency.

How does this skill handle testing and mocking?

It mandates real backend connections and prohibits mocking to ensure tests validate actual behavior, while requiring a 100% pass rate before any commit.

Why does this skill forbid the use of 'else' blocks?

It enforces the use of guard clauses, which reduce code indentation and cognitive load, ensuring the main logic (the 'happy path') is always at the lowest indentation level.

Developer Tools

Enforces high-discipline development rules including guard clauses, real-world testing, and zero-placeholder policies for production-ready codebases.

The Production Code Standards skill (core-rules) is designed for developers who prioritize software integrity over speed. It implements a strict architectural philosophy that eliminates nested logic through guard clauses, forbids the use of mocks in favor of real integration testing, and removes technical debt by prohibiting TODOs and placeholders. By enforcing Test-Driven Development (TDD) for bugs and requiring 100% test pass rates before commits, this skill ensures that every line of code is robust, maintainable, and ready for a production environment.
