One thing to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Use when implementing any feature or bugfix. Routes to the core Red-Green-Refactor loop, test quality guidance, rationalization handling, examples, or stuck-state recovery.

Test-Driven Development (TDD)

TL;DR

Use when writing or fixing code
Cycle: Red → Green → Refactor
Rule: no production code without a failing test first
Next: cm-execution or cm-code-review

When to Use

new features
bug fixes
refactors
behavior changes

The Iron Law

NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST

Choose the Need

Need to execute the normal TDD loop?
└─ YES → Red-Green-Refactor

Need help designing or reviewing test quality?
└─ YES → Test Quality

Need to counter "skip TDD" rationalizations?
└─ YES → Rationalizations

Need a worked bug-fix example?
└─ YES → Bugfix Example

Are you blocked or unsure how to continue?
└─ YES → Stuck / Debugging

Need	Summary	Load
Normal execution	core TDD loop and verification	`references/red-green-refactor.md`
Test quality	what good tests look like	`references/test-quality.md`
Reinforcement	anti-rationalization guidance	`references/rationalizations.md`
Example	concrete bug-fix walkthrough	`references/bugfix-example.md`
Recovery	how to proceed when stuck	`references/stuck-debugging.md`

Load Rules

Load red-green-refactor.md for normal execution.
Load test-quality.md when designing or reviewing tests.
Load rationalizations.md only when the user or agent is trying to bypass TDD discipline.
Load bugfix-example.md only for coaching or example use.
Load stuck-debugging.md only when blocked.

Non-Negotiables

Watch the test fail before writing production code.
Keep implementation minimal until green.
Refactor only after green.
Re-run verification after each meaningful change.

The Bottom Line

Write the failing test first. Pass it minimally. Refactor only after green.
