Does it support checking specific directories?

Absolutely. You can use the --files flag to point to specific directories like 'app/Services' or target individual files to speed up the feedback loop.

Can I specify the PHPStan analysis level?

Yes, you can use the --level flag to set any valid PHPStan analysis level (e.g., --level=7) to match your project's strictness requirements.

Why does this skill run in a fork context?

Static analysis can be resource-intensive. Running it in a forked sub-agent keeps your main conversation responsive and prevents the analysis results from overwhelming your main context window.

Will this skill help me fix the errors it finds?

Yes, the skill provides a summary of suggested fixes and can use the --fix=true flag to help generate and suggest specific code corrections.
