Worked on the nodejs/node repository to update the CLI documentation for the --cpu-prof-name option, focusing on clarifying which value patterns are supported. Used Markdown and technical writing skills to explicitly state that patterns such as ${hhmmss} and ${pid} are not accepted, ensuring the documentation accurately reflects the CLI’s actual behavior. This update aimed to reduce user misconfigurations and lower support overhead related to CPU profiling. The work demonstrated attention to documentation standards, cross-team validation between code and docs, and a methodical approach to aligning user guidance with real-world tool functionality, ultimately improving onboarding for performance profiling workflows.
