invariant-analysis

What problem does it solve?

This Skill helps you rigorously define and assess the security guarantees of a system by formalizing claims as invariants and evaluating the feasibility of their verification.

Core Features & Use Cases

• Claim Enumeration: Identifies explicit and implicit security claims within system designs.
• Invariant Formalization: Translates claims into precise mathematical predicates.
• Assumption Analysis: Uncovers and classifies hidden assumptions required for claims to hold.
• Feasibility Assessment: Evaluates the practicality of formally verifying these invariants using various tools and techniques.
• Use Case: When designing a new financial transaction system, use this Skill to ensure that claims like "no double-spending" and "all transactions are eventually confirmed" are precisely defined, their underlying assumptions (e.g., network reliability) are understood, and a practical verification strategy is proposed.

Quick Start

Analyze the security claims in the provided system design document and formalize them as invariants.
