I thought we were going to have to do our own finetune for this tbh

The worst agent failures don't always throw errors. We're building Runtype Trace Signals with @Cloudflare's Clairic + Clef Flash to find frustration and unanswered questions. The goal: analyze every trace, at scale, without breaking the bank. runtype.com/changelog/trace-…

Trace Signals: your agent finished. Did it actually help?

Find frustration, repeated requests, and unanswered questions in your agent traces. Cloudflare's specialized models make broad trace analysis affordable.

Using decision models to help AI agents in shared spaces pass the vibe check

@RuntypeLabsOct 19
Putting an AI agent behind an @mention in Slack doesn't solve the noise problem. It just moves the routing work onto your team. Someone still has to notice a message matters, remember which bot handles it, and tag it in. Here's how we're using Jev and small decision models to move beyond the @mention: runtype.com/blog/jev-in-the-…

Beyond the @mention

Decision models let channel agents listen continuously, pull in the right scrollback, and step in without waiting for an @mention.

Hope to do more events like this! Moving to the bay area for me was mostly about feeling like I was closer to the cutting edge when everything's changing, and sharing what I've learned feels like giving back.

Last night our CPO @Runtypical joined @Cloudflare and @stripe at Cloudflare's SF HQ to talk about selling to agents. The room was full of tech leaders, startup founders, and retailers. 🧵

Big fan of @mattpocockuk 'grill me' skill but the new version asks a bunch of questions at once, which is better but also means a lot of typing and it doesn't fit inside Claude Code's AskUserQuestion limits. So I built a UI for it that uses MCP Elicitation to pop up. github.com/bookernath/grill-…

Cloud platforms gave developers reliable primitives for compute, unlocking tremendous productivity and giving birth to the modern SaaS era. Agentic products need a different set of tools in order to get maximum leverage out of LLMs; models by themselves are unrefined ore, waiting to be formed into useful things by the right forge. I wrote about how we think about this emerging layer at Runtype, and propose a set of the new primitives: runtype.com/blog/new-primiti…

The new primitives

Cloud platforms gave developers compute, storage, databases, networks, queues, and observability. Agentic products still depend on that foundation, but a new application layer is emerging above it.

Great to see how teams are deploying Runtype at Agent Native Builders Hackathon at @Cloudflare HQ! Dozens of agents were built in 2 days in this room. Huge thanks to the teams who participated as well as the sponsors @Cotal_AI @MitosisLabs @nebiusai @tenki @immersivecommon

Cold startup time on Cloudflare workers IS harmed by a larger bundle, even if it has dead or lazy code. This is not expressed by the startup time metric in wrangler.

The context mentions and commands I was working through on persona.js are live 😎 Very helpful if you are building agent UI related to documents or code All of it's open source and plugable Check it: - persona-chat.dev/context-men… - persona-chat.dev/slash-comma…
