Property Test Designer

Agent skill
1 skill

Design property-based tests — generate hundreds of random inputs and assert invariants that must hold for ALL of them — to surface the edge cases hand-picked examples never reach. Use when code has a large input space (parsers, serializers, encoders, math, data transforms), when a bug keeps slipping through despite green example tests, or when you can't enumerate every case worth checking.

Install with

Supported by the Atlas install prompt. Skill-specific requirements vary.
