What is the primary purpose of the TLA+ Spec Review skill?

It is designed to help users review TLA+ specifications for logical correctness, structural integrity, and readiness for model checking using a systematic checklist.

Can it detect common TLA+ syntax errors?

Yes, it specifically checks for frequent mistakes such as incorrect EXCEPT syntax and the improper use of primed variables in Init predicates or invariants.

Is this skill useful for beginners in formal methods?

Absolutely. It enforces best practices and highlights common pitfalls, making it an excellent educational tool for those learning TLA+ and formal system modeling.

Does this skill integrate with actual TLA+ tools?

Yes, it provides guidance and checklists for using MCP tools like sany_parse for syntax checking and tlc_check for model validation.

Security & Testing

Reviews and validates TLA+ specifications for correctness, completeness, and adherence to formal verification best practices.

The TLA+ Specification Reviewer is a specialized skill designed to audit formal models of concurrent and distributed systems. It provides a systematic framework for checking TLA+ formulas, module structures, and state transitions, ensuring that specifications are logically sound before they undergo intensive model checking. By identifying common pitfalls such as incorrect EXCEPT syntax, misplaced primed variables, and incomplete initializations, this skill helps engineers build more robust formal models and streamline the verification process with SANY and TLC tools.
