Worked on the docker/cli repository to improve documentation accuracy and user experience, focusing on clarifying the semantics of exit code 126 for the docker run command. Addressed a documentation bug by updating Markdown files to specify that exit code 126 reflects the exit status of the executed container command, reducing potential confusion for users and support teams. The technical approach involved careful review and revision of existing documentation to ensure alignment with actual CLI behavior. Leveraged skills in documentation and Markdown to enhance onboarding materials, ultimately decreasing the risk of misinterpretation for common command-line usage scenarios within the Docker ecosystem.
