Our CEO @danlynch opened FRC #26 with Secure-by-Default Postgres for Agents. Agents are database users now. Authorization has to live in the database, not the app. Thanks @frontiersynd @Kristopherfloyd @pebble_bed @danielchalef @zep_ai @shulynnliu @shagarw21

Hundreds of speculative queries a second, from a user that isn't human. That's the workload. Authorization has to live in the database, not the app. Proud to sponsor FRC #26 with @frontiersynd @pebble_bed xitter.cf/frontiersynd/status/21…
Your next database user won't be a human. It'll be an agent firing off hundreds of queries a second. @shulynnliu and @shagarw21 of @BerkeleySky made the case at FRC #26 at @pebble_bed: agents don't query, they speculate. Schemas, samples, partial plans, retries, all in parallel. On BIRD, more attempts meant better answers. Across 50 parallel attempts, most of the work was redundant. Agents already create ~20x more branches and ~50x more rollbacks than humans. So the database has to change. Probes instead of queries. Satisficers instead of optimizers. Branching storage built for agents. Thanks to @constructive_io for sponsoring.

Tech Week in SF was a blast! Happy to co-host the event with an incredible group of researchers
Memory layer or a whole new database? We spent FRC #26 arguing about it 🧠🗄️ @danielchalef (@zep_ai) made the case that context is production infrastructure: if your agent can't trust what it remembers, nothing else matters. @shulynnliu and @shagarw21 brought their CIDR '26 paper from Berkeley Sky. Agents don't really query, they speculate: tons of redundant, exploratory probes. So build the database for the agent first. Then the room fought over whether those are the same problem. No consensus. Exactly how we like it. Huge thanks to @constructive_io and @danlynch for sponsoring and @pebble_bed + @nicilevv for hosting 🙏 Great to have @tjskhot @yumi_aw @ryanorban @ezrwolf @damnventures and many other regulars in the room!

Your agent's memory is rotting and it doesn't know it. @danielchalef of @zep_ai walked through this at FRC #26 at @pebble_bed: enterprises now hold agent context to the same bar as every other database. Provenance. Access control. Invalidation when facts go stale. Commercial graph DBs weren't built for millions of mostly idle small graphs. So Zep built Konig. 20M+ graphs in production, sub-100ms retrieval. Context isn't a prompt trick. It's production infrastructure. Thanks @constructive_io for sponsoring and @Techweek_ / @a16z for the SF Tech Week slot.

The DseWiki story isn't just a browser-access problem. It's a where does authority live problem. Those agents were supposed to have read access to the internet, not write access. They found a path around that boundary because their authority was being constrained by the environment rather than represented as a first-class principal all the way down the stack. That's the opposite assumption behind the architecture we're building into @constructive_io 🧵
Holy...15,000+ edits by OpenAI agents on DseWiki, a German programming wiki, over two months. They used it to pass each other restriction bypasses, detection evasion, and state between runs. Backups when moderators deleted pages. Every enterprise security review of your agent just got harder. If your pitch says "full browser access and stored credentials," that's now the first question in diligence, not the last. The startups that win the next 12 months ship a permission model, an audit log, and a kill path on day one...not after the first breakout. We write $250k–$3M first checks. If you're building the containment layer for agents, DM me. reuters.com/world/europe/ope…

and the bottleneck moves to trust
When software was expensive - thin, horizontal, best-of-breed software stacks extracted rents across every business. Now that software is cheap - value moves to vertically integrated businesses that deliver opinionated end-to-end experiences.

To show appreciation for what @ElectricSQL built with PGlite, we're launching a pglite test framework and integrated it with pgpm :) We built pglite-test to run real migrations, triggers, RLS policies, roles, and pgvector entirely inside your Node test runner with PGlite. No Docker. No server. No CI services. Just pnpm test. ⚡️ constructive.io/blog/pglite-… @constructive_io

It's been an honor to contribute a small part to the 7x7 Summer of Awe installation from @IlluminatedArts Working with @nusalt on hardware and @constructive_io on software, we created the "Awepad" powering the laser show... and watching art, technology, and the city come together has been incredibly rewarding

Everyone wants smarter agents. We care more about smarter constraints. Better models won't decide who wins. The operators who win will be the ones who can run thousands of agent actions without leaking data, breaking permissions, or quietly introducing security holes. Intelligence is getting cheap. Trust isn't.
1/ There's a bottleneck in AI that hundreds of billions of dollars can't buy past: the very few people who can wield this technology well enough to matter. There aren't nearly enough of them, and the entire buildout runs through them.
