Agentic traces contain perfect information about an agent’s behavior with every plan, action, and retry. But that information gets lost in a sea of JSON. So we built AgentPrism: open source React components that turn traces into visual diagrams for debugging AI agents. You can plug in your OpenTelemetry data and see your agent’s process unfold: messages, tool calls, retries. @QuotientAI automatically monitors, analyzes, and improves AI agents. Being able to review traces quickly is paramount for their research, and for their customers. “Dealing with agent traces was one of the biggest frustrations for our researchers and a huge time sink. All of that has gone away since adding AgentPrism, and we’re excited to bring that functionality to our users.” — @JuliaANeagu

Can’t wait for this event and to share how we’re leveraging Rails + Inertia + SQLite with activerecord-tenanted to build enterprise software! Some fun parts in running this stack on edge computers for offline first and syncing seamlessly to multi-tenant dbs per customer on the cloud server. Seems complex, but can’t wait to share how Rails has all the building blocks to make this so simple.

Entering the speaker lounge: Jason Bosco (@jasonbosco) He's the founder of Typesense, a bootstrapped, open-source search engine built on Rails. It handles 10+ billion searches every month. We're excited to have him on stage.

A massive thanks to everyone who bought early bird tickets for @sfrubyconf. We sold out this tier! General and support tickets for the conference are available: luma.com/sfrubyconf2026

Are you back from RubyConf and already missing the Ruby community? Come join us in SF this November. Expert speakers, organized networking sessions, and a day of fun community events. Grab your tickets: luma.com/sfrubyconf2026

A few months ago we shared a skill for making your app discoverable by LLMs, but does it really work? We measured two months of server-side LLM traffic to our website to answer the question. Find out which agents read HTML, which read Markdown, what llms.txt actually does, and the technique that got zero hits: evilmartians.com/chronicles/whi…

@sfrubyconf CFP is open for just one more week! This year's edition is framed around startups, so we're looking, first of all, for talks on building, launching and growing with Ruby/Rails. Share your story! cfp.sfruby.com

We're building the conference around human connection. Organized networking sessions will give Ruby engineers the chance to: - Learn from the best and get to know them in small groups - Find users for their OSS - Land a new job See you there: shorturl.at/7nLdY

Your coding agent can now install our engineering best practices packed as skills and code like a Martian. Examples of what you can find inside this page: - llms-visibility to make your site discoverable by Claude, ChatGPT, Perplexity. - storybook-workbench to audit your React and Vite UI, see hidden components, and learn the state of your design system health - layered-rails to write, refactor, and review Rails code based on the principles from the Layered Design for Ruby on Rails Applications book by @palkan_tula Also, skills for using Inertia Rails, writing good read me pages, and realising an npm package with no token left to steal. All here: evilmartians.com/agent-skills

You can't know what to fix if you don't audit your UI. The issue with vibe-coded apps is that they're written in a way that doesn't break any builds, but they're still full of dead components. For designers who weren't used to working primarily on the codebase, this makes slop feel hidden. That's why @strongeron, one of our product designers, created Storybook Workbench. It's a set of agent skills that work one command at a time and turn your codebase into stories in Storybook. There, you can see exactly what's inside your repo, what are all the icon and components used, and what's dead code. This tool makes it so much easier to clean up after. See how it works in the link below.

The real winners are the ones who sold out the early bird tickets and are coming to the conference. 😅 Get general tickets: luma.com/sfrubyconf2026

I've vibe coded a useful thing for Rubyists over the weekend. Audition is a linter/fixer that gets your code Ractor-ready: static analysis powered by Shopify's rubydex, plus dynamic probes that actually run your code inside Ractors and report what breaks github.com/yaroslav/audit…

Have had this setup for our @HiSaeloun blog and all sites including miru.so earlier this year! Also setup MCP agents where possible. Most sites are being interacted more with AI and this is a checklist you should go over from @evilmartians !

Install it once and run each command whenever you need: evilmartians.com/chronicles/sto…

Only 4 tickets left in the early bird sale! Share this with your Ruby friends and invite them to come. Let's sell out! luma.com/sfrubyconf2026

A huge THANK YOU to everyone who's already bought tickets to the conference. 🫶 Every notification from Luma puts a smile on our faces. See you in a few months!

Just got my ticket to @sfrubyconf!

We decided to extend early bird sale for the SF Ruby Conference for a day. There are only 15 tickets left at $350. Grab them before the price goes up: luma.com/sfrubyconf2026
