🚀 High-performing teams don’t just work harder — they move faster. What’s the difference? 👉 Communication that actually works. When teams communicate clearly, decisions speed up, problems surface earlier, and collaboration becomes frictionless. Research consistently shows that strong communication and trust are at the core of high-performing teams. That’s exactly what this blog from Neat explores — how removing communication barriers unlocks real momentum for teams. 💡 If your team is dealing with: • Endless meetings with little progress • Misalignment across functions • Slow decision-making …this is worth a read. neat.no/stories/high-p… #Leadership #Teamwork #Collaboration #FutureOfWork #Productivity #HybridWork

And using the Kotlin MCP SDK for that server (github.com/modelcontextpr…)....part of shared KMP code in the project and using Ktor to make requests to @ClimateTRACE endpoint to get the data

The interactive chart support in @claudeai is really nice. This is based on data from an MCP server in the ClimateTrace KMP sample (github.com/joreilly/Clima…)

@riggaroo @zsmb13 Are tickets transferrable....though would need to head directly to Munich after it's over 😃

@zsmb13 Sorry it didn't work out this year 🫠

After almost a decade in the community, contributing as a GDE for years and even being a Googler (and an I/O speaker!) at some point, this is the first time I got this invitation. While it's nice to get it, you'll find me in Munich instead 😉 kotlinconf.com

@JamesWard @claudeai @ClimateTRACE Just data. Claude came up with UI based on the data.

@joreilly @claudeai @ClimateTRACE Nice! Are you returning structured data or the actual UI with MCP UI?
