Use this skill when running or interpreting VCSDD adversarial reviews. Provides calibration guidance for the Adversary agent, finding severity classification, and anti-leniency enforcement patterns.
Run Phase 3 (adversarial review) for the active VCSDD feature. Spawns a fresh vcsdd-adversary agent with zero Builder context to review implementation against spec. Produces binary PASS/FAIL verdict per dimension.
Create a git commit for the current VCSDD phase. Auto-generates a conventional commit message from state.json including phase, sprint, gate verdict, and affected bead IDs. Tags with vcsdd/<feature>/phase-<id>.
Run the strict-mode sprint contract review after Phase 2c. Spawns a fresh vcsdd-adversary instance to review `contracts/sprint-N.md` and writes a PASS/FAIL verdict under `reviews/contracts/sprint-N/output/`.
Run Phase 6 (convergence check) for the active VCSDD feature. Validates four-dimensional convergence: finding diminishment, finding specificity, criteria coverage, and duplicate detection.
Use this skill during Phase 6 convergence checks. Provides four-dimensional convergence analysis, hallucination detection, and duplicate finding identification.

| origin | VCSDD |
Every requirement MUST use EARS (Easy Approach to Requirements Syntax):
| Pattern | Syntax | Example |
|---|---|---|
| Ubiquitous | THE SYSTEM SHALL [action] | THE SYSTEM SHALL log all authentication attempts |
| Event-driven | WHEN [trigger] THE SYSTEM SHALL [action] | WHEN user submits empty form THE SYSTEM SHALL return ErrorCode.EMPTY |
| State-driven | WHILE [state] THE SYSTEM SHALL [action] | WHILE user is authenticated THE SYSTEM SHALL display dashboard |
| Conditional | IF [condition] THEN THE SYSTEM SHALL [action] | IF retry count exceeds 3 THEN THE SYSTEM SHALL lock account |
| Optional | WHERE [feature] THE SYSTEM SHALL [action] | WHERE audit mode enabled THE SYSTEM SHALL record all reads |
Separate code into:
## Edge Cases
### Input Edge Cases
- Empty input: [expected behavior]
- Maximum length input: [expected behavior]
- Special characters / unicode: [expected behavior]
- Null / undefined: [expected behavior]
### State Edge Cases
- First-time run (no state): [expected behavior]
- Concurrent modification: [expected behavior]
- Interrupted operation: [expected behavior]
### Error Edge Cases
- External dependency unavailable: [expected behavior]
- Partial failure: [expected behavior]
- Timeout: [expected behavior]
