tlaplus-guided-code-repair

Automatically repair C/C++ code violations detected by TLA+ model checking. Takes a program, TLA+ specification, and TLC counterexample trace as input, then generates minimal code modifications to eliminate the violation. Use when: (1) TLC model checker reports an invariant violation, deadlock, or temporal property failure, (2) You have a counterexample trace and need to fix the corresponding code, (3) You need to understand how a TLA+ violation maps to program-level bugs, (4) You want to validate repairs by re-running TLC. Supports safety properties (invariants), liveness properties (temporal logic), and deadlock detection.

# TLA+ Guided Code Repair

Automatically repair C/C++ code based on TLA+ model checking violations. This skill analyzes TLC counterexamples, identifies root causes in the implementation, and generates semantically justified repairs.

## Repair Workflow

Follow this sequential process when given a TLA+ violation:

### 1. Parse the Counterexample

Use `scripts/parse_tlc_trace.py` to extract structured information from TLC output:

```bash
python scripts/parse_tlc_trace.py trace.txt
