Use when implementing any feature or bugfix, before writing implementation code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<skill>
<purpose>
Write the test first. Watch it fail. Write minimal code to pass. If you didn't watch the test fail, you don't know if it tests the right thing.
</purpose>
<triggers>
<rule>Use when implementing any new feature, before writing implementation code.</rule>
<rule>Use when fixing any bug — write a failing test that reproduces it first.</rule>
<rule>Use when refactoring or changing behavior in existing code.</rule>
</triggers>
<warning level="hard">
NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST. Violating the letter of the rules is violating the spirit. Write code before the test? Delete it. Start over. No exceptions without your human partner's permission.
</warning>
<rules>
<rule>Test-first is non-negotiable. RED before GREEN.</rule>
<rule>Wrote code before the test? Delete it. Don't keep it as "reference", don't "adapt" it, don't look at it. Delete means delete. Implement fresh from tests.</rule>
<rule>Exceptions (ask your human partner first): throwaway prototypes, generated code, configuration files.</rule>
</rules>

How to install
mdr add brandonfla/bearpaws/test-driven-development@sha256:714509918e831732The line at the top of this page pins the label git:20260501.88e4ec8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
