What platforms are supported?

The core logic applies to Rust projects globally, though the specific process management commands in this skill are currently optimized for Windows PowerShell environments.

How does it detect errors if the exit code is 0?

It parses the standard output and error logs for specific keywords like 'panic', 'error', or 'failed' which often occur during initialization even if the process doesn't crash immediately.

Does this work for long-running servers?

Yes, it is specifically designed for long-running processes like servers or daemons by using a timeout-based execution window to prevent the test from hanging.

Why is this skill better than just running 'cargo check'?

Unlike cargo check, this skill actually runs the binary for a short period to catch runtime errors, missing environment variables, and panics that compilation won't detect.

Security & Testing

Validates that Rust applications and daemons launch successfully without runtime errors or panics through automated execution testing.

This skill provides a comprehensive safety net for Rust developers building long-running applications like background daemons, system tray apps, and web servers. It automates a multi-step validation workflow that goes beyond simple compilation by executing unit tests, performing code checks, and then running the actual binary within a controlled 5-second window. By capturing and analyzing stdout and stderr logs for specific failure patterns like panics or configuration errors, it ensures that your application is truly ready for deployment and won't fail immediately upon startup due to runtime environment issues.
