This skill should be used when the user asks to "write tests first", "run TDD", "verify red phase", "check failing tests", or when practicing test-driven development. Ensures tests fail before implementation.
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 Phase Verifier
Ensures tests are written BEFORE implementation and fail initially.
## Purpose
In TDD:
1. **RED**: Write failing tests
2. **GREEN**: Implement to pass
3. **REFACTOR**: Improve while green
This skill enforces Step 1.
## Activation Triggers
This skill activates when:
- Running /dev-loop command
- Creating test files before implementation
- Mentioning "write tests first"
## Verification Process
### Step 1: Check Implementation Exists
```python
# If implementing UserService.create_user:
# Check if method exists and has logic
import inspect
from app.services import UserService
method = getattr(UserService, 'create_user', None)
if method:
source = inspect.getsource(method)
if 'pass' not in source and 'raise NotImplementedError' not in source:
# Implementation exists!
WARN: "Implementation found before tests"
```
### Step 2: Run Tests
```bash
pytest tests/test_new_feature.py -v --tb=short
```
### Step 3: Verify Failures
Expected output:
```
FAILED tests/test_new_feature.py::test_create - AssertionError
FAILED tests/test_new_feature.py::test_validate - AttributeError
```
### Step 4: Report
```

How to install
mdr add smicolon/ai-kit/red-phase-verifier@sha256:0b30b717a30c732cThe line at the top of this page pins the label git:20260215.92455aa, 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.
