Hey team!
If you’re developing for Ring, or thinking about trying it out, it’s a big week with a new OAuth 2.0 account-linking flow, free trials that now convert to paid automatically, and word that the team is making this community an active channel for their updates. It’s a great time to jump into their community and say hi!
On the Fire TV side, Phynd launched a free cloud-gaming beta, a new no-hardware surface if you publish games to the living room.
Principal Product Manager for Vega Christian Van Boven published an announcement for React Native 0.83 on Vega. While this went live last week, so you’re already probably aware, the new announcement has a lot of great details, like a list of the new features and a FAQ. I highly recommend reading it over.
Looking ahead, we’re at Gamescom in Cologne later this month, and the fall agent-conference run kicks off with Sr. Dev Advocate Giovanni Laquidara at AGNTCon in Shanghai, and Dev Advocates Kourtney Meiss, Anisha Malde, and Giovanni at Agent Conf in Warsaw, so we hope to see you there!
I also pulled a couple of reads I liked this week, on getting more out of Claude Code and picking the right Kiro app.
Let’s dive in!
Dev Updates
React Native 0.83 is now in early access on Vega SDK v0.24 — It bundles React 19.2 with concurrent rendering on by default and better tooling (React Compiler and RN DevTools), and Amazon Devices Builder Tools ships an MCP server to help you upgrade from RN 0.72.
Ring adds Partner-Initiated OAuth 2.0 account linking — A second linking method lets partners start the flow from their own app using the standard OAuth 2.0 authorization code flow with PKCE, instead of only from the Ring App Store.
Ring free trials now convert to paid automatically — For trials starting on or after August 7, a finished trial rolls into your app’s paid plan unless the customer cancels first, shortening the path from trial to paid.
React Native 0.87 ships upstream — The core release adds a Strict TypeScript API, a Metro update, Swift Package Manager support, and AGP 9 compatibility, worth tracking ahead of the Vega SDK picking it up.
Announcements
The Ring team is making this community an active channel for developers
- Ring will now post product announcements, release notes, Knowledge Base guides, and Q&A here, giving a shared place to ask questions and see platform changes explained alongside the official docs.
Phynd launches a free cloud-gaming beta on Fire TV
- The ad-supported streaming service is in beta on Fire TV Sticks and Ember smart TVs in the US, installable from the Amazon Appstore, opening a no-hardware distribution surface for publishers bringing games to the living room. Phynd’s 60-second launch trailer is in Dev Posts below.
Fire TV’s Adaptive Display is now available for everyone
- VP of Fire TV, Ads, and Appstore Aidan Marcuss shared that the Adaptive Display is now available for everyone using a Vega device (Fire TV Stick 4K Select or Fire TV Stick HD): switch it on and text, menus, and content get bigger and easier to navigate. See the Adaptive Display instructions to enable it. Worth turning on to see how your own app’s layouts hold up at larger sizes.

Dev Posts
If you read two things this week, make it these: Which Kiro app should I pick? maps Kiro’s new IDE, CLI, web, mobile, and Crew surfaces so you can pick the right one per task, and Maximizing the value of your Claude Code sessions is a practical guide to keeping long sessions lean so your tokens go to the work, not stale context.
Which Kiro app should I pick?
Kiro isn’t one thing anymore. It’s now a family of surfaces sharing a single agent harness: the IDE and CLI are generally available, Web and Mobile are in preview, and Crew (open source, and originally an internal Amazon tool called MeshClaw) handles the most autonomous work with persistent memory, scheduled jobs, and async multi-agent orchestration. Because they all draw on the same engine, your setup and sessions travel across them, so you pick per task rather than once and forever. If you’ve only known Kiro as an IDE, this is a good map of where it’s gone.
Amazon Alexa+ assistance is the way consumers ‘actually want to shop’: VP
Daniel Rausch, VP of Alexa and Echo, sits down with Yahoo Finance’s Josh Lipton and brings numbers: customers who try Alexa+ are 25% more likely to sign up for Prime, music listening is up 25%, and shoppers who use Alexa inside the Amazon app spend more than 40% more per order since Alexa for shopping launched about 90 days ago. The part worth a builder’s attention is the pattern he keeps returning to — getting someone “all the way to done” instead of handling one step of the journey, with services like Uber and OpenTable finishing the task inside a single conversation. Three minutes, and a clear read on what Amazon wants integrations to do.
Maximizing the value of your Claude Code sessions
By Lydia Hallie

Everything you read into a Claude Code conversation gets re-sent on every turn, so efficiency comes from keeping the context relevant, not from minimizing tokens. The piece walks through the habits that get you there: run /clear between unrelated tasks, set /model and /effort up front since changing them mid-session breaks the prompt cache, @-mention files instead of typing paths, and push noisy commands to a subagent (or add quiet flags) so their output doesn’t linger. It also covers /context to audit what’s loaded and /compact before a break while the cache is still warm. Worth a read if your sessions run long and you’ve watched the context window fill up.
MCP: When to Use It (And When You Shouldn’t)
AWS Dev Advocate Ramses Mata makes the case for when MCP earns its place and when it doesn’t. MCP is the right call for reusable, shared, or remote tools, but every capability you expose sits in the context window every turn whether the model uses it or not, so a plain function call is sometimes the better trade. He walks the N-agents-by-M-tools integration problem, how the protocol works, a before/after demo (stale training answer vs live docs), and when lighter alternatives win.
