In this episode, Cassidy and Abby are joined by Helen Hou-Sandí to discuss accessibility, the Model Context Protocol (MCP), and ‘Maintainer Tiny Wins’ at GitHub. The discussion features engineering improvements, open standards, and community-driven enhancements for developers.

GitHub’s Year in Review: Accessibility, MCP, and Tiny Wins

Hosts: Cassidy Williams, Abby, and guest Helen Hou-Sandí (GitHub Accessibility Engineering Manager, WordPress lead developer)

Topics Covered

• Maintainer Tiny Wins: Incremental, timeboxed improvements like smarter PR reviewer panels, one-click merge conflict resolution, and WebP support. These changes cumulatively save millions of developer minutes daily and improve user experience at scale.

• Accessibility Initiatives: Helen Hou-Sandí shares how small accessibility fixes (e.g., adjusting border colors) can drive larger UX improvements and spark systemic changes, benefiting all users.

• Model Context Protocol (MCP): The rise of MCP as an open standard for improved context sharing in codebases and across tools.

• Open Source Tools: Introduction of GitHub's new open source accessibility scanner GitHub Action, as well as other community-driven solutions like git-history-cleaner and Project Bluefin.

• Supporting Non-Code Contributors: Strategies and acknowledgments for those contributing beyond code—documentation, accessibility, and community initiatives.

• AI and Open Source: Discussion on the role of AI as a new contributor and how automation and assistive tools impact open source maintenance.
