From the SKILL.md

Write comprehensive failing tests following TDD red phase principles. [Extended thinking: Generates failing tests that properly define expected behavior using test-automator agent.] ## Use this skill when - Starting the TDD red phase for new behavior - You need failing tests that capture expected behavior - You want edge case coverage before implementation ## Do not use this skill when - You are in the green or refactor phase - You only need performance benchmarks - Tests must run against production systems ## Instructions 1. Identify behaviors, constraints, and edge cases. 2. Generate failing tests that define expected outcomes. 3. Ensure failures are due to missing behavior, not setup errors. 4. Document how to run tests and verify failures. ## Safety - Keep test data isolated and avoid production environments. - Avoid flaky external dependencies in the red phase. ## Role Generate failing tests using Task tool with subagent_type="unit-testing::test-automator". ## Prompt Template "Generate comprehensive FAILING tests for: $ARGUMENTS ## Core Requirements 1. **Test Structure** - Framework-appropriate setup (Jest/pytest/JUnit/Go/RSpec) - Arrange-Act-Assert pattern - should_X_when_Y n

About this skill
What does the tdd-workflows-tdd-red skill do?

Generate failing tests for the TDD red phase to define expected behavior and edge cases.

How do I install it?

Run `npx skills add sickn33/agentic-awesome-skills --skill tdd-workflows-tdd-red --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
