Individual skill
specification-generator
Generate formal specifications including preconditions, postconditions, invariants, and contracts from code or requirements. Use this skill when documenting APIs, creating formal verification annotations, defining function contracts, specifying class invariants, writing design-by-contract code, or preparing code for formal verification. Supports multiple specification languages including JML, ACSL, Dafny, Eiffel contracts, and documentation annotations.

# Specification Generator
Systematically generate formal specifications from code and requirements. Produces preconditions, postconditions, invariants, and behavioral contracts that enable verification, documentation, and design-by-contract programming.
## Core Capabilities
### 1. Precondition Generation
Define required conditions before execution:
- **Parameter validation** - Valid ranges, types, states
- **Object state requirements** - Required object states
- **Resource availability** - Files exist, connections open
- **Authorization checks** - Permission requirements
- **Null safety** - Non-null parameter requirements
