Worked on documentation maintenance for the coinbase/x402 repository, focusing on improving accuracy and clarity for developer onboarding. Addressed a documentation bug by updating the network identifier in the @x402/fetch README from Base Sepolia to Base Mainnet, ensuring the documentation accurately reflected the intended network for the fetch functionality. This change reduced the risk of misconfiguration and minimized support inquiries by aligning the documentation with the module’s actual behavior. Utilized Markdown for documentation updates and applied strong attention to detail in commit messaging, supporting easier audits and pull request reviews. The work emphasized documentation skills and careful repository maintenance.
