semgrep-rule-variant-creator

To port Semgrep rules to a different programming language, this Skill analyzes applicability for equivalent constructs, generates test files first, and translates the rule into the target language directory structure.

Automating Semgrep rule creation for multiple languages is handled by analyzing target language constructs, writing tests before rule translation, and automatically generating the required rule and test directories.

Yes, you need Python and Semgrep installed as dependencies to execute tasks, analyze applicability, and generate the rule and test files required for language porting.

Yes, applicability analysis checks whether a Semgrep rule applies to a target language by verifying equivalent constructs before the rule translation and test generation process begins.

Writing tests before creating Semgrep rule variants ensures accuracy and coverage by establishing expected results first, allowing the translated rule to be validated immediately against the target language constructs.

Porting Semgrep rules across languages is limited to target languages with equivalent constructs, meaning rules relying on language-specific features without direct equivalents cannot be automatically translated.
