How do I disable assertions in production?

You can disable assertions by setting the PERL_ASSERT_ENABLED environment variable to 0 before your module is loaded.

What is the Syntax-Keyword-Assert skill?

It is a specialized Claude Code skill that helps developers implement zero-cost runtime assertions in Perl using the Syntax::Keyword::Assert library.

Can I use this for object type checking?

Yes, it is highly effective for asserting that objects are of a specific class or can perform specific methods using 'isa' or 'can' checks.

How does 'zero-cost' benefit my Perl application?

When assertions are disabled (e.g., in production), the code within the assert statements is completely removed at compile-time, meaning there is zero performance overhead.

Does Claude help write the assertion logic?

Yes, Claude uses this skill to analyze your logic and automatically suggest appropriate invariants and preconditions to improve code reliability.

安全与测试

Implements zero-cost runtime assertions for Perl applications using Syntax::Keyword::Assert for high-performance debugging.

关于

This skill enables Claude to implement and manage Syntax::Keyword::Assert within Perl projects, providing a powerful mechanism for runtime debugging and contract programming. It allows developers to define critical invariants and preconditions that are strictly enforced during development but completely removed at compile-time in production environments via environment variables, ensuring there is no performance penalty. It is particularly useful for complex algorithms, data validation, and ensuring object-oriented integrity without compromising execution speed in live environments.
