Test-driven development with vertical slices, behavior-focused tests, and incremental red-green-refactor cycles. Emphasizes integration-style tests that verify behavior through public APIs, not implementation details; tests should survive refactors unchanged Requires vertical slicing (one test → one implementation → repeat) instead of horizontal slicing (all tests first, then all code), preventing brittle, behavior-insensitive test suites Includes planning phase to confirm interface changes, prioritize behaviors to test, and design for testability before writing code Provides refactoring guidelines covering duplication extraction, module deepening, and SOLID principles, applied only after all tests pass

Cuando usarlo

• Use this skill when the task matches the package name, repository context, or skills.sh topic: tdd.
• Prefer it when a repeatable workflow is better than a one-off prompt: setup, review, design, deployment, automation, research, media generation, or operational checks.
• For production work, read the linked repository and install command before allowing the agent to run scripts or modify files.

FAQ

Is tdd an agent, a prompt, or a skill?
It is a skill: a reusable package of task-specific instructions and supporting files that an agent can load when the user's request matches the workflow.

Should I install it automatically?
Only after checking the repository, install command, audit status, and whether the user wants this capability in the current agent environment.

What makes it useful for AIDreamHub users?
It helps users discover practical agent capabilities from the open skills ecosystem and compare them by task, source, install count, and operational risk.
