Class is back in session 🎓 The Kiro University Challenge starts today. A one week crash course for Kiro. 📚 7 lessons: steering, hooks, MCP, Powers + more 🛠️ Build a project as you go 🏆 Up to 5,250 credits Syllabus here: spr.ly/6011BGbvT5 #KiroUniversity

Back to school. 📚 New semester, new lessons. Something exciting is coming to Kiro next week. Build as you learn. Stay tuned. Open to everyone. Not just students. #KiroUniversity

Kiro Web + cloud sessions are generally available, with cloud configuration. Build from the browser, or start a new session from the CLI or IDE. Pick up the same session later from your browser, CLI, IDE, mobile, or another machine. What changed 👉 spr.ly/6010BG6kYE

Are AI coding agents actually getting better? Six months of diagnostics data say yes, with caveats. Kiro’s agents use LSP-based diagnostics to catch type errors, unresolved imports, and undefined symbols. Newer models aren’t just making fewer errors, they’re checking broader sets of files and self-correcting better. Full breakdown 👉 spr.ly/6018B1x1dG

System prompt behavior is hard to predict. An instruction that looks fine in isolation can break in cases nobody tested for. We built an LLM-judge pipeline to catch it before it ships. 27 candidates screened. Kiro CLI behavioral quality issues down 32%. Full breakdown 👉 spr.ly/6016B1Qlyg

Kiro powers now support Agent Plugins. ⚡ No more packaging the same skill three different ways for three different clients. Publish once to the open specification (built by AWS, Cursor, Microsoft, OpenAI, Vercel), install anywhere the standard is supported. Existing powers still work, nothing breaks.

1/ Introducing Kiro Crew. 👻 An open source, persistent development workspace that runs on your hardware and works wherever you are. It started as an internal tool called MeshClaw, shaped by hundreds of contributors across the company. Now it’s yours to build on too. Read the full story → spr.ly/6016BEhBkK

Mark your calendars. Tuesday is going to be a good one. Comment below your guesses?👀👇

Today is Kiro's birthday, and we come bearing a gift.🎁 GPT-5.6 (Sol, Terra, Luna) just went live across Kiro IDE, CLI, and Web, three tiers built to match the task in front of you: max performance with Sol, balanced cost and capability with Terra, high-volume speed with Luna. Available now for Pro, Pro+, Pro Max, and Power. Here's to year one, and to shipping like this all year two.🎈 spr.ly/6016BEnp74

Sonnet 5 is live in Kiro 👻 Anthropic’s most agentic Sonnet yet, stronger reasoning, tool use, and coding than 4.6, at the same Sonnet-class pricing. Plans before it edits, runs longer without supervision, checks its own output. Experimental support for Pro, Pro+, Pro Max, and Power. Sign in with AWS IAM Identity Center, Google, GitHub, or AWS Builder ID. Learn more 👉 spr.ly/6019BDL2Wf

Could Kiro build a complete MCP server from one prompt? @VitorHansen ran the experiment. The output was impressive. The architecture it chose was more so 👉 spr.ly/6014BDQdO8

API docs. Framework quirks. Semicolons in the wrong place. Every developer absorbs that tax. Johannes Koch, Principal Architect at FICO, found a solution with Kiro. Spec-driven development that generates detailed design docs automatically. Structured enough to actually ship from. What part of your SDLC would you automate first?

4/ 📱 Kiro is now on iOS. Native app built for real engineering work that gives developers a new surface to kick off, monitor, steer, and interact with their Kiro sessions directly from their phone. Check in while you grab coffee. Available in preview for Pro, Pro+, Pro Max, and Power customers. iOS 26+ required. → spr.ly/6017BDPpht
