Next week, the Tessl team is heading to AI Engineering World's Fair 2026, and we couldn't be more excited to spend a few days with the community talking about the future of AI engineering.

If you're attending, come and find us at Booth L-G48. We'll be demoing our latest product, sharing what we've been building, and talking all things agentic development with engineering teams from around the world.

Come and meet the team

At Tessl, we believe skills are the new code. Treat them that way.

Tessl enables development teams to continuously build, test, distribute and optimize agent skills with the security and governance of enterprise software.

Throughout the event, our technical team will be running live demos at the booth and chatting with attendees about everything from coding agents and agent workflows to evaluation, context management and harness engineering. Whether you're just getting started or already deploying agents in production, we'd love to hear what you're building.

We're also running a competition throughout the conference, with prizes including:

• 🎁 Ray-Ban Meta Smart Glasses
• 🎟️ A ticket to AI DevCon in New York this November

Unveiling Tessl Agent

AI agents shouldn't just write software—they should continuously improve how software gets built.

At AI Engineering World's Fair, we'll be unveiling Tessl Agent.

Build your software factory, one workflow at a time.

Tessl Agent makes your agents more autonomous over time. It continuously scans your pull requests, session logs and tickets for recurring mistakes and opportunities, automatically opens improvement PRs, turns repeated patterns into automated workflows, and ships them through GitHub Actions—creating a software factory that compounds week after week without slowing feature delivery.

If you'd like to see it in action, stop by the booth for a live demo.

The conversation we're most excited about: Harness Engineering

Every conference has a theme. This year, we think it'll be Harness Engineering.

AI models are getting smarter every month. The challenge is everything around them.

Agents need context. They need evaluation, testing, guardrails, observability and workflows that help them operate reliably in production. In short, they need a harness.

We believe Harness Engineering is becoming one of the defining disciplines of modern AI engineering, and we're looking forward to hearing how the community is tackling these challenges.

Catch our talks

We're delighted to have two Tessl speakers presenting on Thursday, July 2.

Coding Agents Don't Scale Themselves. Neither Do Your Teams: The Rise of Agent Enablement

🕜 1:30–1:50 PM

Patrick Debois, AI Product Engineer

Coding agents are transforming software development, but the context that drives them is still managed with ad hoc prompts, copied rule files and undocumented practices.

Patrick introduces the Context Development Lifecycle—a framework for treating context with the same engineering discipline we've spent decades applying to code—and explores how teams can build a feedback loop that continuously improves agent performance over time.

Harness Engineering: The New Core Skill for Agentic Developers

🕝 2:50–3:10 PM

Dru Knox, Head of Product & Design

As coding agents become more capable, success depends less on writing code and more on upgrading your codebase so agents can reliably succeed.

Dru introduces the core loop of Harness Engineering, the common improvements teams are making today, and how Tessl's Harness Engineering Agent helps developers scale those improvements across their software factory.

Join our community event

We're also hosting an evening fireside discussion:

Harness Engineering: Building Reliable AI Systems

📅 Wednesday, July 1 | 6:00 PM

Featuring Steve Yegge and Dru Knox, this conversation explores the emerging discipline of Harness Engineering and what it takes to move AI systems beyond experimentation into reliable production software.

Together they'll discuss the systems surrounding AI models—from context and evaluation to testing, observability and guardrails—followed by audience Q&A and networking with the AI engineering community.

Leadership dinner

Alongside the conference, we're also hosting an invite-only leadership dinner, bringing together engineering leaders and AI practitioners for an evening of conversation about the future of agentic development.

We're looking forward to sharing ideas with some of the people helping define where this industry goes next.

See you next week

AI Engineering World's Fair has become one of the best places to connect with the people shaping the future of software engineering, and we can't wait to be part of it.

Whether you want to see Tessl Agent in action, chat about Harness Engineering, attend one of our talks, or simply swap ideas about building reliable AI systems, we'd love to meet you.

Come and see us at Booth L-G48.

Or, if you'd like to guarantee some time with the team, book a meeting with us through the AI Engineering World's Fair app.
