Can it detect errors that only happen while the game is running?

Yes, the skill includes a Runtime Check step that enters Play Mode, monitors for exceptions for several seconds, and reports any issues found before stopping the editor.

How does the self-correction loop work?

If an error is detected during compilation or testing, the skill analyzes the console output and attempts to fix the code, repeating the verification process for up to three rounds.

When should I use this skill?

It is best used after editing .cs files, shaders, .asmdef files, or package manifests to ensure that your changes haven't broken the project's build or runtime state.

Does this skill require external tools?

Yes, it requires the unity-cli tool to be accessible, which allows Claude to communicate with the Unity Editor via the command line.

What does the Unity Preflight Check skill do?

It automates a sequence of verification steps in the Unity Editor, including checking for compilation errors, running unit tests, and validating runtime stability after code changes.

Game Development

Automates Unity Editor verification workflows including compilation checks, console log analysis, and automated testing.

Unity Preflight Check is a specialized skill designed to streamline the game development cycle by automating essential verification steps after script or asset modifications. It manages the entire 'edit-compile-test' loop by polling the Unity Editor state, clearing and analyzing console logs for errors, executing EditMode tests, and even performing runtime checks in Play Mode. By providing Claude with direct control over the Unity CLI, it enables an autonomous feedback loop where the AI can detect, analyze, and attempt to fix compilation and runtime errors before they disrupt the development flow.
