## Description

This project is a set of git pre-commit hooks designed to automate the formatting, linting, and validation of Terraform configurations. It functions as an infrastructure as code linter, security scanner, cost estimator, and documentation generator to ensure code quality before commits are finalized.

The tool distinguishes itself by providing specialized capabilities for infrastructure workflows, such as scanning templates for security vulnerabilities and hardcoded secrets, calculating projected cloud spending against budgets, and automatically extracting module definitions to populate readme files.

The broader capability surface covers infrastructure code formatting for Terraform and YAML files, dependency management for provider lockfiles and version constraints, and syntax validation for both Terraform and Terragrunt inputs.
