Overview

TODO: Should probably just be a comprehensive single page on linting, and then reference rules separately.

This section contains guides and reference documentation for Acton's linter.

acton check helps catch common issues and enforce best practices in Tolk code. It supports project-wide checks, target-specific checks, automatic fixes, JSON output, SARIF reports, GitHub annotations, and GitLab Code Quality reports.

Basic Usage
