Identifies and fixes subtle logic flaws, comparison errors, and edge-case bugs in PHP codebases.
This skill empowers Claude to perform deep static analysis of PHP code, specifically targeting 'hidden' bugs that traditional linters might miss. It detects common pitfalls such as assignment within conditionals, inverted logic, missing match/switch cases, and off-by-one errors. By using sophisticated grep patterns and structural analysis, it helps developers prevent runtime crashes and unexpected behavior by ensuring boolean expressions, short-circuit evaluations, and return values are handled correctly according to PHP best practices.
