How do I resolve a 'Java heap space' error during checking?

You can increase the memory limit by adding a higher -Xmx value (e.g., -Xmx8192m) to the extraJavaOpts or by reducing the constants in your .cfg file to limit the state space.

What are symmetry sets in TLA+ model checking?

Symmetry sets tell TLC that certain values (like a set of identical server IDs) are interchangeable, allowing it to skip redundant state evaluations and speed up verification.

How do I generate a TLC configuration file?

You can use the /tla-symbols command within this skill to automatically generate a template .cfg file based on the symbols defined in your TLA+ specification.

What is the difference between /tla-smoke and /tla-check?

/tla-smoke performs a quick validation to catch obvious bugs in seconds, whereas /tla-check runs an exhaustive exploration of all reachable states for full verification.

Can Claude help me interpret an invariant violation?

Yes, this skill includes guidance for using the trace-analyzer agent to break down counterexample traces and identify the exact sequence of actions that led to the failure.

Seguridad y Pruebas

Verifies TLA+ specifications using the TLC model checker to identify logic bugs, invariant violations, and temporal property failures.

The TLA+ Model Checking skill provides a comprehensive workflow for formal verification of distributed systems and complex algorithms. It guides users through preparing specifications, generating and optimizing TLC configuration files (.cfg), running exhaustive state-space explorations, and interpreting complex counterexamples. Whether you are debugging concurrency issues, validating safety invariants, or tuning model checker performance for large state spaces, this skill ensures your system designs are mathematically sound before implementation begins.
