TDD Enforcement Algorithm

What problem does it solve?

Developers (and AI agents) often bypass Test-Driven Development (TDD) under pressure, leading to untested code and technical debt. This Skill provides a strict algorithmic decision tree to enforce test-first development, including mandatory deletion of untested code, ensuring robust, well-tested software.

Core Features & Use Cases

• Test-First Mandate: Algorithmically checks for a failing test before allowing implementation code to be written.
• Untested Code Deletion: Provides a recovery algorithm that mandates deleting any code written without a preceding failing test, overriding "sunk cost" rationalizations.
• Invalid Conditions List: Explicitly invalidates common excuses for skipping TDD (e.g., "too simple," "time pressure"), ensuring compliance.
• Use Case: When an agent is about to write a new function, this Skill ensures it first writes a failing test. If the agent accidentally writes code without a test, the Skill forces deletion, guaranteeing TDD compliance and preventing untested code from entering the codebase.

Quick Start

Before writing any implementation code:

The Skill will check: "Does a failing test exist for this code?"

If NO: STOP writing code. Write the failing test first.

If you've already written code without tests:

The Skill will prompt: "Delete the untested code. Execute: git reset --hard OR rm [files]."
