Worked on targeted documentation improvements in the CockroachDB docs repository, focusing on correcting the JSONB containment operator guidance. Addressed a documentation bug by updating jsonb.md to replace the incorrect @> symbol with the correct <@ operator, ensuring that the documentation accurately reflects JSONB containment semantics and aligns with actual testing behavior. Collaborated with another contributor to review and validate the change, demonstrating attention to detail and cross-functional teamwork. Utilized Markdown for technical writing and documentation updates, resulting in clearer onboarding materials and more reliable developer guidance. The work emphasized correctness, clarity, and collaborative documentation practices within the repository.
