red-phase-verifier — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited red-phase-verifier (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Ensures tests are written BEFORE implementation and fail initially.
In TDD:
This skill enforces Step 1.
This skill activates when:
# 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!

Red phase confirmed!
Implementation may now proceed.WARNING: Tests passed before implementation!
Failing tests: 0/5
This indicates:
1. Tests don't test new functionality
2. Tests have trivial assertions
3. Implementation already exists
Action: Regenerate stricter testsPARTIAL RED PHASE
Tests failing: 3/5
Tests passing: 2/5
Passing tests may be:
1. Testing existing functionality (OK)
2. Trivial assertions (NOT OK)
Review passing tests:
- test_helper_exists: assert helper <- TRIVIAL
- test_constant: assert X == X <- TRIVIAL
Action: Strengthen or remove trivial testsUNEXPECTED FAILURE TYPE
test_create_user: SyntaxError in test file
Tests should fail due to:
- AssertionError (expected behavior not met)
- AttributeError (method doesn't exist yet)
- NotImplementedError (placeholder)
NOT due to:
- SyntaxError (test file broken)
- ImportError (missing dependency)
- TypeError (wrong arguments)
Action: Fix test file syntaxWhen red phase not verified:
CANNOT PROCEED TO GREEN PHASE
Red phase requirements not met:
- 2 tests passed before implementation
- 1 test has syntax error
