SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Credo static analysis helps you catch code quality problems in Elixir early, but manually running, interpreting, and fixing issues can be slow and error-prone.

Core Features & Use Cases

Run strict Credo checks: Execute Credo with --strict to surface consistency, design, readability, refactor, and warning issues.
Report actionable results: Summarize issue counts and list each issue with file and line context.
Fix detected issues: Auto-fix style/readability/refactor issues where safe, then re-verify with a clean strict run.

Quick Start

Run the Credo strict check and fix mode by asking for: "Use the credo skill to fix all Credo warnings and verify the project passes mix credo --strict."
