suggest-tests

To find missing unit tests, this Skill analyzes your source code and existing test suites to identify uncovered public functions and important edge cases, outputting a prioritized list of test suggestions grouped by source file.

The best way to suggest test coverage improvements is to analyze source code against existing tests to identify untested serialization gaps and missing integration points, producing a grouped list of actionable test suggestions prioritized by likely bug-catching value.

Test discovery works with repositories using standard build or manifest files and common testing frameworks where test and source directories can be discovered by globbing, automatically detecting your language and directory conventions.

You cannot generate test code automatically, as this Skill outputs a numbered, grouped list of suggested tests with descriptive names and explanations without writing code, helping you focus QA efforts on high-risk code paths.

Focusing on high-impact missing tests reduces regression risks by targeting untested public functions, edge cases, and serialization gaps that matter most, rather than simply increasing overall coverage percentages.
