What problem does it solve?

This Skill helps you add a new variable to a TLA+ specification without changing its behavior, ensuring the new variable is properly declared, initialized, and integrated into all relevant constraints.

Core Features & Use Cases

  • Update the VARIABLE declaration block to include the new variable.
  • Initialize the new variable in Init.
  • Update all UNCHANGED statements (including converting single-variable UNCHANGED to a tuple) and ensure the new variable is included.
  • Update the vars tuple (if it exists) to include the new variable.
  • Optionally extend TypeOk invariants to constrain the new variable.

Quick Start

Provide the TLA+ specification and the desired variable name, and I will add the variable, initialize it, and update all UNCHANGED statements and related structures to preserve the model's semantics.
