What's inside
- Skill name
jnk-attack- Description
- Generate adversarial tests that try to break a feature — boundary values, invalid classes, error guessing, property invariants, state and concurrency attacks — so a green suite is as close to ironclad as tests get. User-invoked only via /skill:jnk-attack. Point it at a feature or change; it writes and runs the attack suite, proves each test can fail, and reports the residual risk.
