We’re adding support for MCP Tasks and Elicitations in Claude. Tasks let Claude give plugins long-running jobs such as deep research and report back when they’re done.

Did you know that even one lying fsync() on just one node can make a distributed Raft cluster lose data?

Had a great time giving some live demos of the Temporal Agent Harness on @temporalio's Vibe Check livestream - thanks for having me @nyghtowl! youtube.com/live/PIKhDydUegY…

The 4th round of SIGMOD 2027 has *659* submissions. This is 2-3x more than previous years! I downloaded the abstracts & compared against last 10yrs of SIGMOD/VLDB papers. I then evaluated them to see how writing changed since ChatGPT in 2022. Many papers are clearly LLM written.

🥳 Google is donating Agent Substrate to CNCF, and our submissions is accepted today! This effort has now the full potential to become the underlying compute runtime layer for all agentic systems. github.com/cncf/sandbox/issu…

Preview of WIP at Temporal. Agent Harness is in a different category from coding harnesses like Pi, Codex, or Claude Code. It’s an outer harness providing durability and policy. It mediates how your agents interacts with the world and with one another. Please give feedback!

Network effects 💪
A painful part of working with your data has always been that your live data and historical data are stuck in separate systems: the order a customer just placed lives in your database, while their last five years of orders sit in a data lake in S3. And answering a real question usually needs both at once (is this a normal purchase for them, or should we flag it?), and to do that you had to move the data together first, copying history out of the data lake into your database (or the other way around), because the database couldn’t read it where it lived. That meant guessing ahead of time which data you’d want, keeping a second copy of it all, building pipelines to move it, and constantly syncing so the two didn’t drift apart. A lot of plumbing, and slow going, all before you could answer one question. And even then, the answers were only as fresh as your last sync. That now changes with Aurora PostgreSQL, which can call your live data and historical data in S3 together, in a single query. No copying, no pipelines to keep in sync. And it’s fast, because we’ve built in DuckDB, a popular open source engine that’s really good at reading and analyzing data right where it’s stored. DuckDB reads the open formats like Parquet and Iceberg already sitting in your data lake, so there’s nothing to convert or move. As folks build AI agents into their apps, the data their agent needs will depend on the task in front of it. Being able to query that specific data live, instead of copying it over just in case, is gonna be a big help for builders. aws.amazon.com/blogs/aws/ama…

long shot: person at portola who called me the jev guy, took a photo with the team, then gave us "hot" stickers - can you share it? 🙏 we don't leave the office much and I think we'd treasure the pic forever 🥹

Harnesses matter. The green dots are the new frontier.
Today we're excited to share Strands Harness. Strands Harness makes it easier to build reliable, cost-effective, agents with any model. It's open source, too! And equal or better performance to proprietary harnesses with 28% fewer tokens!

Emphasis on probabilities makes Jev natural for something like auto-approval / reviewer escalation. Follow @JasonSteving for more on this.
Jev powered "auto mode" in the Temporal Agent Harness is such a natural fit. Jev is a big unlock for efficient agent oversight. Very excited to see how straightforward it was to integrate along existing harness seams. More to come here for sure.

Started out playing a game with Jev but the capability unlock is serious. It's neat to see how easily it drops into Temporal's experimental Agent Harness. Will share more soon...

have feedback on @muse phone calls? send them to @jrlevine!
ok @Muse + 📞 is maybe the worst kept secret in the industry but also maybe my fave Muse feature. for those starting to get access, send feedback/requests! we're ramping sloooowly as we keep a close eye on quality/reliability.

Today we're launching the Agents API, a brand new way to build Agents in the cloud, backed by the Codex harness. Bring along all your favorite tools and connectors, connect it to any sandbox, and let Astra cook. Can't wait to see what you whip up 👨‍🍳 openai.com/index/introducing…
