invariant-inference

Automatically infer loop invariants for code verification and correctness proofs. Use when analyzing loops to identify properties that hold throughout execution, generating assertions for verification, proving loop correctness, or documenting loop behavior. Supports Python, Java, C/C++, and language-agnostic analysis. Generates invariants as code assertions (assert statements). Triggers when users ask to infer invariants, find loop properties, generate loop assertions, prove loop correctness, or verify loop behavior.

# Invariant Inference

## Overview

Analyze loops and automatically infer invariants—properties that remain true throughout loop execution. Generate these as code assertions for verification and correctness proofs.

## Workflow

### 1. Identify the Loop

First, locate and understand the loop to analyze:

**Loop types to recognize:**
- `for` loops with index variables
