What problem does it solve? Manually figuring out which test command a project uses and interpreting raw test output is repetitive and error-prone, especially when switching between Rust, Swift, and Python codebases. This Skill detects the right framework, runs the appropriate tests, and presents results in a clear, consistent format. ## Core Features & Use Cases - Framework Detection: Inspects Cargo.toml, Package.swift, Xcode projects, pyproject.toml, pytest.ini, and Makefiles to pick the correct test command automatically. - Scoped Test Runs: Runs only tests related to changed files where possible, falling back to the full suite when needed. - Failure Diagnosis: Reports failing test names, assertions, and file locations, then helps investigate the root cause without modifying source code. - Use Case: Before committing changes to a Rust workspace, ask the assistant to run the tests; it executes cargo test, summarizes 42 passed and 0 failed, and confirms the suite is green. ## Quick Start Ask the assistant to run the tests and tell you whether they all pass before you commit your changes.
