From the source SKILL.md

Test-driven development is a rhythm, not a ritual you perform for the commit log. The value comes from writing the test first and watching it fail for the right reason, which forces you to state the behavior before you build it. Writing the code first and backfilling tests that pass on the first run is theater: those tests echo the code's own mistakes and are blind to what it got wrong.

What this skill does

Tdd Rhythm is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/tdd-rhythm/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when building code with a clear behavioral spec and you want the tests to drive the design.

Who uses this skill

The Tdd Rhythm Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems.
