# TDD
This is a Critique Marketplace source link for a public agent skill. It does not vendor the upstream SKILL.md; use the links below to inspect and install the maintained source.
## Upstream links
- Source: https://github.com/mattpocock/skills
- skills.sh listing: https://www.skills.sh/mattpocock/skills/tdd
- Upstream install: `npx skills add mattpocock/skills`
## Use this when
- A behavior change needs a tight regression test before implementation.
- A review finding should be locked down with a failing test before the fix lands.
## Review before installing
- Keep tests proportional to risk; do not force a full TDD loop for copy-only or mechanical changes.
- Ask the agent to show the failing assertion before the implementation when practical.
## Critique usage
When this skill shapes a PR review, cite the exact upstream version or commit you inspected. Treat source-linked skills as discovery entries until your team has reviewed the upstream SKILL.md and any scripts it brings with it.Version history
