Agents Hour

Abhi walks through Mastra Code, a new open-source coding agent with observational memory that compresses context without losing it.
When we built Observational Memory, we needed a way to test it in production. Instead of a standard bot, we dogfooded it: we built a coding agent and used it ourselves. Writing code every day quickly revealed whether the memory actually worked.
Eventually, something clicked. Long, multi-day coding sessions ran smoothly, without hitting the compaction limits that trip up other agents. The agent actually seemed to understand the conversation. That gave us confidence to release Observational Memory... and the agent itself also became something worth sharing.
The core innovation is the Harness primitive. Rather than just a coding agent, Harness can power any type of agentic workflow: customer support, design tools, electrical engineering, and more.
In this demo, you’ll see the Mastra Code CLI, a production-ready coding agent, and how Corbin from Artifact used the Harness to create an in-app agent for electrical engineering. Same primitive, completely different use case.

Shane and Abhi break down the biggest AI news from the past few days. 
Anthropic identified industrial-scale distillation attacks on Claude by DeepSeek, Moonshot AI, and MiniMax. Anthropic also released a groundbreaking report analyzing millions of AI agent interactions using Claude. Software engineering makes up ~50% of all agentic tool calls, but there's emerging use across back office automation, marketing, finance, and more. Claude Code Security launched in a limited research preview.
Stripe is shipping 1,300+ AI-generated PRs per week. And they're made by... Minions?
Code Mode for MCP is becoming a standard part of the MCP ecosystem. Amp claims the coding agent is dead. We also cover skills benchmarks (smaller models with high-quality skills beat raw Opus), trajectory explorer for agent traces, Vercel AI Gateway video support, Taalas custom silicon for AI inference, Google's Pomelli Photoshoot feature, and the GitHub Star Party pick: superpowers framework.

Shane and Abhi welcome Charlie Holtz from Conductor to AI Agents Hour. Charlie shares how frustration with managing multiple Claude Code instances led to building Conductor. They discuss Conductor's July 2025 launch as the first agent orchestration Mac app, early design choices, and its impact on the market.
Charlie outlines a future in which agents run 10x longer and require less supervision, along with new tools such as Kanban boards and a CEO dashboard. The conversation covers multi-agent coordination, designing for both humans and AI, and the importance of user feedback.Watch a live demo showcasing Conductor's parallel agents, code review, GitHub integration, and continuous deployment with GitHub Actions and Vercel. They also explore ways to keep users within the app while allowing flexibility, code-editing strategies, and upcoming remote workstation support.

It's time for another AI News roundup with Shane and Abhi! This week was absolutely massive. Matt Shumer's viral article about AI automation, which describes his own job being automated in real time, has reached 84 million views. Anthropic raised $30 billion at a $380B valuation (one of the largest private raises in tech history). Claude Sonnet 4.6 launched with a 1M token context window. And the Chinese model tsunami is real: Qwen 3.5, GLM 5.0, MiniMax M2.5 (nearly Opus-level at 1/8 the cost), and DeepSeek v4 rumors.
We also cover Google's Gemini 3.1 Pro, WebMCP native browser support in Chrome 146, OpenAI's agent workflow tips, Peter Steinberger joining OpenAI, Lyria 3 music generation, Kimi Claw integration, and the explosion of agent platforms (Oz, Browserbase Functions, and a former GitHub CEO raising $60M for "version control for agents").
Plus: Real production stats from Ramp (57% of merged PRs from background agents), Letta's context repositories, and why Mastra's Observational Memory is becoming the reference implementation for agent memory.

Tyler Barnes, founding engineer at Mastra, introduces Observational Memory. It is a new memory system for AI agents that achieves state-of-the-art results on LongMemEval with a completely stable context window.
Unlike semantic recall (which uses RAG and invalidates prompt caching), Observational Memory compresses conversations into dense observations while maintaining a stable, fully cacheable context.
The result: 94.87% accuracy on LongMemEval with GPT-5 mini. This is the highest score recorded by any memory system to date.
In this conversation, Tyler explains how the system works, why it outperforms raw context, and how you can integrate it into your agents in under 20 minutes. We also dive into the research, the benchmarks, and what's next for Observational Memory.

Shane and Abhi welcome Kiet Ho, cofounder of Superset, to discuss how Superset evolved from simple WorkTree management into a full-featured tool with file editing, automation, cloud support, and multi-agent orchestration.

Shane and Abhi cover this week's top AI developments. The OpenClaw agent goes viral amid growing security concerns over its shifting identity. Moonshot AI's Kimi K2.5 ties for first place on Design Arena. Google DeepMind unveils Project Genie, advancing world model technology. Anthropic previews a new model and explores AI coding with Claude Cowork plugins. Plus, updates on developer tools, humanoid robots, and emerging AI models.

Today we discuss the Mastra 1.0 launch, we talk about the things we are learning, we discuss ClawdBot (renamed to MoltBot and now OpenClaw). We also discuss agent skills, new models, and how agents are reading more docs pages than humans.

Today we announce Mastra is officially 1.0! We talk with Kyle from ElectricSQL (and formerly Gatsby) about Durable Streams. Allie joins us to discuss the code review security problem that can be caused by generated AI code. Finally, we cover all the AI news from the last week including ads in ChatGPT, the Langfuse/Clickhouse acquisition, and the OpenAI / Cerebres partnership.
