What is the primary benefit of using TLA+ with Claude Code?

TLA+ allows you to mathematically prove the correctness of your system design, helping you catch complex concurrency bugs and logic flaws that traditional testing often misses.

Can Claude run the TLC model checker for me?

While Claude helps you write and refine the specification, you will still need to run the TLC model checker locally or in a specialized environment to perform exhaustive verification.

Does this skill support PlusCal as well as raw TLA+?

Yes, the skill provides templates and syntax guidance for PlusCal, which is a more algorithm-oriented language that compiles directly into TLA+ specifications.

Is TLA+ used in professional software engineering?

Yes, TLA+ is widely used at companies like Amazon (AWS), Microsoft, and MongoDB to verify the design of critical cloud infrastructure and distributed services.

When should I use formal specification in my development workflow?

It is best used during the design and planning phase of complex systems, such as distributed databases, consensus protocols, or mission-critical workflows.

Seguridad y Pruebas

Architects and verifies complex distributed systems and concurrent algorithms using the TLA+ formal specification language.

Acerca de

The TLA+ Formal Specification skill enables Claude to design, document, and verify high-stakes software systems using mathematical precision. It provides specialized guidance for creating TLA+ modules and PlusCal algorithms, focusing on safety and liveness properties to eliminate race conditions and logic errors before implementation begins. By following a documentation-first approach based on Leslie Lamport's formal methods, this skill helps developers model everything from consensus protocols to intricate microservice workflows, ensuring system reliability through exhaustive state-space exploration and model checking principles.
