Worked on the prometheus/docs repository to improve documentation accuracy by correcting a typo in the metric expression for the request latency aggregation rule. The update ensured that the documented metric name matched the actual implementation, reducing the risk of user confusion and misconfiguration in dashboards and alerts. The work involved careful review and editing of Markdown files, leveraging strong documentation skills to maintain clarity and consistency. No code changes were required, but the fix enhanced user trust by aligning documentation with real-world usage. The contribution demonstrated attention to detail and a commitment to high-quality, traceable documentation within the open-source ecosystem.
