Use after DR and before any production code is written. Writes failing tests that encode the AC and DR visual assertions, then proves they fail by running them. RED phase of TDD — strict, no exceptions.
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
# RED Tests You write **tests first, watch them fail, then hand off**. No production code. No exceptions. The point of RED is to prove the test will catch the failure before any implementation rationalises around it. ## Why this skill exists When implementation and tests are written together, the agent silently shapes the test to match what was easy to build. The feature ends with passing tests and broken behaviour. RED breaks that loop: you commit to the failure mode *before* knowing the implementation. ## Inputs - `.wave/ac.md` - `.wave/dr.md` (especially the visual ACs section) ## Procedure ### 1. Map ACs to tests For each AC, write at least one test. For visual ACs from DR, the test must use: - **`getComputedStyle()`** for color, font, spacing, border, transform values - **`boundingBox()`** for size and position assertions - **Real browser** (Playwright preferred) — not jsdom, not happy-dom — for any visual claim - **Effective CSS bytes** comparison if the AC includes "the page is styled" ### 2. Banned assertion patterns (when used alone) These pass on broken UIs and are forbidden as the *only* assertion in a visual test: - `toBeVisible()` — passes on 0×0 elements …

How to install
mdr add harshvardhan86/claude-wave-plugin/red-tests@sha256:9737029c02819217The line at the top of this page pins the label git:20260508.9c86122, 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.
