Detects and repairs critical exception handling flaws in PHP code to prevent silent failures and data loss.
The PHP Exception Guard skill enables Claude to perform deep static analysis on PHP codebases, specifically targeting risky error-handling patterns. It identifies common but dangerous practices such as swallowed exceptions, generic catch-all blocks, and broken exception chains that obscure the root cause of failures. By surfacing these issues, the skill helps developers maintain robust, observable, and reliable PHP architectures that align with Clean Architecture and SOLID principles, ensuring that errors are handled gracefully rather than ignored.
Key Features
01Checks for missing @throws documentation in PHP method headers.
02Warns against 'return' or exceptions inside finally blocks that suppress errors.
03Detects lost context in exception re-throwing to preserve stack traces.
0445 GitHub stars
05Flags generic Exception or Throwable catching that masks fatal system errors.
06Identifies swallowed exceptions and empty catch blocks that hide bugs.
Use Cases
01Debugging silent application failures where errors are being caught but not reported.
02Refactoring legacy PHP codebases to improve error observability and system reliability.
03Automating architectural code reviews to enforce strict error handling standards.
