Worked on the thoughtbot/guides repository to enhance documentation accuracy and maintain cross-file consistency. Focused on resolving a documentation bug by updating the ai-rules README to correctly reference CLAUDE.md after the CLAUDE instructions were relocated. This Markdown-based change improved user navigation and reduced potential confusion, directly addressing support issues related to outdated links. Leveraged version control best practices to ensure the update was traceable and aligned with recent pull request changes. Demonstrated attention to detail in documentation structure and collaborative workflows, emphasizing Markdown proficiency and disciplined use of Git for managing documentation updates within an evolving open-source project environment.
