[new @arxiv paper] There’s a huge gap between playing with AI skills in a demo and ⚙️ engineering them for production.
In a simple setup, semantic routing feels like enough: the user asks something, the LLM matches the text to a skill description, and executes it. But in real-world production at scale (like @Wix Customer Care), semantic matching alone isn't enough. 🚩
Why? Because semantic matching only looks at what the user says, completely ignoring what the user is actually allowed or able to do.
A user asking to "connect a domain" is a 100% semantic match for the Domain Skill. But if they don't have an active premium plan, executing that skill is a dead end.
In a new arXiv paper by @AshkenaziOrtal, Vitalii Kloz, and Mykhailo Ulianchenko, we present Helpmate’s (Wix’s Customer Care AI agent) architecture: introducing a deterministic executability gate that evaluates account state before candidate skills reach the LLM.
Tested across 756K+ user messages in production:
🎯 59.4% of semantically matched candidates were filtered out because the account state made them non-executable
📉 90.5% reduction in skill context size 228.8M tokens saved
🛡️ In a targeted replay of 1,000 risky conversations, removing the gate caused the model to select a non-executable skill in 7.8% of cases.

The @Wix plugin for @grok Build is here.
Now builders can create apps and sites, connect any frontend to Wix business services through Wix Headless, manage Wix business solutions, and work with Wix MCP, all from the Grok CLI.
We are making it easier to build with Wix wherever developers are already creating. Builders, go build.

"Every morning, these agents have a meeting. They assess what's happening, look at your goals, and build a plan. The business is moving even when you're not looking at a dashboard. That's Symphony" @RonnyElkayam, COO at Wix.

Today is #Headless Day at @Wix! 🚀
The day was kicked off by @IShmool, setting the tone for a company-wide building sprint.
Across Wix, teams are taking this unique day to build real Wix Headless sites - with one big goal: 1,000 awesome sites in a single day.
Why? Wix Headless opens a different way to build on Wix: fully custom frontends powered by Wix’s business infrastructure - eCommerce, bookings, payments, events, and more - all through APIs.
But it’s more 🚩 than building sites.
Every project created today becomes part of a public GitHub repo, helping developers and AI agents discover real examples of how to build with Wix APIs.
1,000 sites. One day. Let’s build! 🏁

"For years, small businesses were promised enterprise tools but got watered-down versions instead. AI changes that equation entirely. And Wix is the mechanism through which it changes." @nirzo , President of Wix.
