60 minutesBuild your own coding agent
Custom coding agents are having a moment. [Ramp](https://www.infoq.com/news/2026/01/ramp-coding-agent-platform/) built one, so did [Stripe](https://stripe.dev/blog/minions-stripes-one-shot-end-to-end-coding-agents), and now you can too! I**n this workshop, you’ll learn how to build a Claude Code and OpenCode-inspired coding agent from first principles using** **[Mastra](https://mastra.ai)****.** We’re hosting this workshop to share what we learned from building Mastra Code. Yeah dawg, it’s a coding agent by Mastra, built with Mastra, and we’re using it to build Mastra 😂. It’s not quite ready to announce (more on that next week), but we just couldn’t wait to share what we’ve learned building it. We’ll walk through the Mastra building blocks that make this possible: * **Memory**, so the agent can remember important context without overfilling the context window * **Workspaces**, so it can read and modify files and execute commands safely * A **harness**, the layer that lets you run the agent, steer it, and see what it’s doing while it works We’ll also show you how we built the streaming **TUI** that lets you watch the agent in real time instead of treating it like a black box. Hosted by * Alex Booker, Developer Experience at Mastra * [x.com/bookercodes](https://x.com/bookercodes) * [linkedin.com/in/bookercodes](https://linkedin.com/in/bookercodes) * Abhi Aiyer, Founder and CTO at Mastra * [https://x.com/abhiaiyer](https://x.com/abhiaiyer) * [https://www.linkedin.com/in/abhi-aiyer-aa41bb42/](https://www.linkedin.com/in/abhi-aiyer-aa41bb42/) * Tyler Barnes, Founding Engineer at Mastra * [https://x.com/tylbar](https://x.com/tylbar) * [https://www.linkedin.com/in/tyler-barnes-882a61193/](https://www.linkedin.com/in/tyler-barnes-882a61193/) _Recording and code examples will be available to everyone who registers._

60 minutesBuild agents with human-like memory
We have been obsessing over agent memory because it is the line between chatbots that forget everything and assistants that actually feel persistent and useful. In this workshop, we will walk you through Mastra’s newly improved memory system, why we built it the way we did, and what we learned along the way, including the work that led to an industry-leading high score on LongMemEval. We will explain the different kinds of memory in Mastra and when to use each one: working memory for tracking user preferences and characteristics, semantic recall for long-term conversation history, and our newly released observational memory. We will share the real tradeoffs, the mistakes we made, and the practical techniques that came out of burning through billions of tokens to get this right. You will see how to build agents that remember users across sessions, recall relevant context from months of history, and reason correctly about time. We will walk through concrete implementation examples and talk about why RAG is still very much alive for agent memory, how formatting and retrieval choices affect accuracy, and what actually matters for performance and cost in production. This is a live, hands-on workshop focused on giving you the mental models and patterns you need to build agents with state-of-the-art memory, not just theory. **Hosted by** * Alex Booker, Developer Experience at Mastra * [x.com/bookercodes](https://x.com/bookercodes) * [linkedin.com/in/bookercodes](https://linkedin.com/in/bookercodes) * Tyler Barnes, Founding Engineer at Mastra * [https://x.com/tylbar](https://x.com/tylbar) * [https://www.linkedin.com/in/tyler-barnes-882a61193/](https://www.linkedin.com/in/tyler-barnes-882a61193/) _Recording and code examples will be available to everyone who registers._

60 minutesIntroduction to Workspaces
We just launched [Workspaces](https://mastra.ai/docs/workspace/overview) 🎉, and in this workshop we are going to walk you through why we built them and what they unlock. We'll share the problems we kept running into while building agents, how those led to Workspaces, and what this means for you as a builder. Along the way, we will cover core features like persistent environments, filesystem access, sandboxes for safe command execution, skills, and search, and how they fit together in practice. Think of this as a guided tour of the ideas behind Mastra Workspaces, focused on helping you build agents that are more reliable, more capable, and easier to reason about. **Hosted by** * Alex Booker, Developer Experience at Mastra * [x.com/bookercodes](https://x.com/bookercodes) * [linkedin.com/in/bookercodes](https://linkedin.com/in/bookercodes) * Nik Aiyer, Founding Engineer at Mastra * [linkedin.com/in/nik-aiyer-72aab7119/](https://www.linkedin.com/in/nik-aiyer-72aab7119/) _Recording and code examples will be available to everyone who registers._

60 minutesBeyond vibes: Measuring your agent with evals
**Relying on “vibes” to see if your agent works doesn’t scale.** In this session, you’ll learn how to build a clear, repeatable signal for how your agent really performs - using evals. Hosted by: \- Alex Booker (Developer Educator @ Mastra) \- Yujohn Nattrass (Software Engineer, working on Evals @ Mastra) We’ll break down what evals are, how they differ from traditional tests, and how they show up in real systems with concrete examples and demos. You’ll see practical patterns for getting started - including LLM-as-a-Judge - and how to use evals to reliably iterate on agents powered by techniques like RAG. We’ll also go deeper into why rigorous evaluation matters - where built-in evals are powerful, where they break down or mislead, and how to pair them with data analysis and a technique called open coding to truly understand and improve your agent’s behaviour over time. Expect a grounded, no-hype look at automated evals designed for people who ship, with time for questions throughout and at the end. _Recording and code examples will be available to everyone who registers._

60 minutesBuild a Slack Agent with Mastra
In this hands-on workshop, Alex Booker and Grayson Hicks from Mastra will show you how to build a Slack AI agent from scratch using Mastra. You will jump straight into code and ship a production-ready agent in around 40 minutes. Slack is an ideal interface for AI agents. It works across web, desktop, and mobile, supports rich inputs like files and media, and keeps context clean through threads. You can work directly with APIs or plug into existing Slack integrations. The session ends by demonstrating how to connect a Mastra agent to Slack with zero code using Mastra Cloud, followed by time for questions.

60 minutesBuild Multi-Agent Networks with Mastra
If you've been working with individual AI agents but find yourself wishing they could collaborate more intelligently, this workshop is for you! Agent Networks in Mastra let you create teams of specialized agents that dynamically work together to solve complex tasks. This session will teach you how to build Agent Networks using Mastra's new Agent Network feature. Unlike traditional workflows where you control every step, Agent Networks use LLM-based routing to automatically decide which agent should handle each part of a task. Build a research network that coordinates web search agents with data analysis agents, or create a content team where writing agents collaborate with editing and fact-checking agents. You'll learn when to use Agent Networks versus Workflows, how to design effective agent collaboration, and how to debug multi-agent interactions. This event is open to all devs and aspiring AI engineers, regardless of background, so feel free to share the invite link. You should be comfortable with basic JavaScript and the command line. This isn't a talk; it's a live workshop where you'll walk away with your own multi-agent network ready to tackle complex, collaborative tasks.

45 minutesBuild agentic workflows with Mastra
2025 has seen AI agents evolve rapidly, but orchestrating complex AI operations remains a challenge. This session is your chance to master Mastra’s battle-tested workflow system to create sophisticated, multi-step AI processes that actually work in production. Workflows in Mastra help you orchestrate complex sequences of operations with powerful features like branching, parallel execution, and state management. The Mastra team will show you how to build resilient, observable AI workflows in less than an hour. Use workflows to create systems like a content generation pipeline that coordinates research, writing, and editing steps. Or design an AI recruiting workflow that gracefully handles user input, database lookups, and external API calls while maintaining context throughout the process. This event is hosted by Alex at Mastra, and joined by Tony — Founding Engineer at @mastra\_ai; previously co‑founder at @vercel, co‑authored @nextjs, developer on @gatsbyjs and Socket.IO. This event is open to all devs and aspiring AI engineers, regardless of background, so feel free to share the invite link. You should be comfortable with basic JavaScript and the command line.

60 minutesBuild and deploy your first agent with Mastra
2025 might be the year of AI agents but this session is your chance to actually build and deploy an agent yourself. AI agents are autonomous systems that can perceive their environments, make decisions, and independently take actions to achieve specific goals. With today’s tools and frameworks, it’s never been easier to build them, and Alex at Mastra how to do it in less than an hour. Use agents to build things like a personalized travel agent that puts together vacations for you. Or use multiple-agents to simulate a ‘team’ of writers and editors that seamlessly collaborate on content. This event is open to all devs and aspiring AI engineers, regardless of background, so feel free to share the invite link. It’s recommended that you have a code editor and node v20+ installed prior to the session. You should be comfortable with basic JavaScript and the command line. This isn’t a talk; it’s a live workshop where you’ll walk away having built and deployed your first AI agent.
