This week, Chris, Andrew, and David dig into a packed mix of Rails news, developer tooling, and the increasingly complicated role AI is playing in everyday coding. They talk about Herb making its way into Rails, the realities of Rails upgrades and stacked PRs, new approaches to Git hosting and object storage, and how Rails is being evaluated in the age of AI agents. They also get into improvements coming to Action Text, Podia’s approach to “flavored” Markdown, the never-ending frustrations of HTML email, and why tools like ArchSpec and Rubydex could become especially useful as more code is generated by LLMs. Hit download now to hear more!

Andrew and David catch up on everything from wild weather and the upcoming Rails World conference to Andrew’s latest deep dive into MCPs (Model Context Protocols). Andrew shares what he’s learned while building an MCP for a Rails side project, including choosing the official Ruby MCP SDK, discovering the limitations of resources versus tools, and wrestling with OAuth and Doorkeeper authorization. They also look ahead to Rails World in Austin, highlighting talks on Active Search, Ractors, Herb, Action Text, Solid Cable, custom Rails generators, and appropriately enough MCPs.

Ernesto Tagwerker joins Chris, Andrew, and David, to talk about how AI is changing Rails development, consulting, and the way teams approach upgrades and maintenance. They discuss using Claude Code for Rails upgrades, the risks of relying too heavily on AI-generated tests and code, and why strong development standards are becoming even more important. The conversation also explores code quality, open AI models, team consistency, and how developers can use AI to work more efficiently without giving up the experience and judgment that good software still requires.
