cfix: Architecting a seamless diagnostic bridge between Linux runtime errors and GitHub Copilot’s LLM-powered intelligence

This is a submission for the GitHub Copilot CLI Challenge What I Built I have engineered cfix , a sophisticated, high-performance command-line interface (CLI) wrapper specifically designed for the Linux ecosystem, with a primary focus on the Ubuntu distribution, to mitigate the cognitive load associated with troubleshooting complex system-level execution failures. In the contemporary software development landscape, the persistent friction caused by cryptic terminal errors often forces engineers into a suboptimal cycle of context-switching, where the transition from the terminal environment to a web browser for error research significantly degrades productivity and disrupts the psychological state of "flow". By architecting cfix as a transparent interception layer, I have created a system that monitors the execution lifecycle of any arbitrary shell command and programmatically captures the standard error (stderr) streams upon process termination with a non-zero exit code.
