Last night Golang Tokyo held its May meetup at Le Wagon Tokyo in Meguro. Two talks, Q&A, and pizza. Thanks to Ondrej for organizing and to Le Wagon for hosting. Good turnout, sharp questions, the right kind of energy for a Wednesday night.

Recap:

Talk 1 — Jason Mooberry: Agentic Coding in Go Using Semantic Tools

I opened with a tour of Go's semantic tooling tradition — go fix, go guru, gopls, gopls MCP, the new pkg.go.dev API, and used it to frame the work Sumato AI has been doing on spath and splan. The thesis: semantic tools for AI agents aren't an exotic ask in Go, they're the next chapter of a tradition this language already has.

We looked at some of the tools we're getting ready to open source that leverage this semantic workflow and a screencap of the side by side comparison using wildcat.

Talk 2 — Yan Shi: database/sql From The Inside

Yan Shi followed with a source-code tour of Go's database/sql package — the standard interface every Go developer who touches SQL ends up working through. The frame was: read the source, learn the design. It was a great deep-dive and I encourage anyone wanting to understand this staple of the Go stdlib to review his deck.

Thanks

Really enjoyed meeting everyone, and getting to discuss how we're all working with AI in Go.

If semantic workflows for AI agents connects to something you're working on, would love to hear from you. More soon!
