no-mocking-validation-gates

What problem does it solve?

This Skill prevents the creation of mock files and mock/stub code patterns that produce false-positive test results and hidden production bugs, ensuring validation is performed against real systems and real user interfaces.

Core Features & Use Cases

• Pre-tool-use Blocking: Rejects write/edit operations that would add test files, mock directories, or known mocking API usage.
• Mock Pattern Detection: Scans for language-specific mock APIs and test patterns to prevent accidental introduction of stubs and spies.
• Developer Workflow Correction: Guides developers through diagnose, fix, and verify steps to make real dependencies available and capture evidence.
• Use Case: Prevents a developer from committing a Jest mock that would hide an API contract regression and redirects them to run the real backend, seed data, and capture evidence.

Quick Start

Run the pre-tool-use hook to block any new mock or test artifacts and follow the three-step correction: diagnose the missing dependency, fix it so it runs, and verify using the real system.
