What problem does it solve? Reviewers of pull requests need a quick, per-test verdict on the tests a PR adds or changes, but full suite-audit reports are too long to post as a PR comment. This skill grades each specified test method individually and produces a compact table mapping every test to a letter grade (A–F), a score band, and a one-line note. ## Core Features & Use Cases - Per-test grading rubric: Scores each test on assertion strength, structure & focus, and anti-pattern hygiene, then combines them into a capped overall letter grade with a score band. - Polyglot support: Handles .NET, Python, TypeScript/JavaScript, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, and C++ by loading language-specific extension guidance before scoring. - PR-comment-ready output: Produces a short summary plus a markdown table with row caps, deterministic ordering, and (new)/(modified) markers when diff context is provided. - Use Case: A CI workflow lists the test methods changed in a pull request; the skill grades each one and posts a table reviewers can scan in seconds to spot tests with no assertions, tautological checks, or wall-clock sleeps. ## Quick Start Grade the test methods OrderServiceTests.CreateOrder_ValidInput_ReturnsOrder and OrderServiceTests.CreateOrder_NullInput_Throws in OrderTests.cs and give me the per-test grade table.
