How does this skill handle existing errors in legacy projects?

It follows a structured hierarchy: first refactoring for better design, then improving phpDoc, and only using baselines or neon ignores as a last resort.

Does it support the creation of PHPStan baselines?

Yes, it can invoke the baseline generator to capture existing errors in legacy projects, allowing you to prevent new errors without fixing thousands of old ones at once.

Is this skill exclusive to the Nette Framework?

While it includes specialized logic for Nette patterns and nette/phpstan-rules, the core PHPStan execution and resolution strategies work for any PHP project.

Why does the skill avoid @phpstan-ignore annotations?

The skill follows Nette standards which prefer keeping code clean of checker-specific annotations, opting for centralized ignore patterns in configuration files instead.

What PHPStan levels does this skill support?

The skill is optimized for high-level analysis, targeting Level 8 for maximum type safety, with Level 7 as the minimum baseline for Nette-based projects.

Security & Testing

Performs deep static analysis using PHPStan and provides structured strategies for resolving complex PHP type errors.

This skill enables Claude to manage the full PHPStan lifecycle within PHP projects, specifically optimized for Nette framework standards. It facilitates running analysis at high strictness levels (7 and 8), interpreting results, and implementing a 'Refactor First' resolution strategy. By prioritizing architectural improvements and precise phpDoc annotations over error suppression, it helps developers eliminate false positives and maintain robust type safety. It also includes specific guidance for Nette-specific patterns, DI extensions, and automated type testing using nette/phpstan-rules.
