SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill tackles the challenge of building complex, distributed, or concurrent systems where subtle bugs can have critical consequences. It formalizes system behavior before implementation, preventing errors and ensuring correctness through rigorous specification and verification.

Core Features & Use Cases

  • Formal Specification with Quint: Define state machines, invariants, and temporal properties using a formal language.
  • Design & Verification Workflow: Guides through planning, creating, verifying, and generating implementation stubs from specifications.
  • Bug Prevention: Catches design flaws and logical errors early, significantly reducing debugging time and costs.
  • Use Case: Design a fault-tolerant distributed ledger. This skill helps specify its consensus protocol, ensuring data consistency and preventing race conditions before a single line of production code is written.

Quick Start

Use the validation-first skill to develop a distributed counter system. The agent will guide you through the entire specification-first development workflow.
