What problem does it solve?
This Skill addresses the pain points of legacy Perl codebases that are difficult to maintain, prone to security vulnerabilities (such as shell injection from two-argument file opens), and fail to leverage modern language features that improve code readability and reliability.
Core Features & Use Cases
- Modern Perl Idioms: Provides up-to-date patterns for Perl 5.36+ including subroutine signatures, postfix dereferencing, native type checking, and context-aware operations.
- Secure & Maintainable Code: Includes best practices for error handling, object-oriented design with Moo, safe file I/O, and common anti-patterns to avoid.
- Use Case: For example, when refactoring a legacy Perl script that uses manual argument unpacking and outdated open calls, this Skill guides you to update it to use the v5.36 pragma, subroutine signatures, and three-argument open with autodie for cleaner, safer code.
Quick Start
Use the perl-patterns skill to update your existing Perl module to use modern v5.36 idioms including subroutine signatures and Moo for object-oriented design.
