Trevin Chow is has more than 25 years of experience in product and design, held product leadership roles at Axon, Sketchy, Nike, and Microsoft, and co-founded Chewsy. He is a core maintainer of Compound Engineering, a plugin for Claude Code, Codex, and other agent harnesses.

Dan and Trevin discuss how AI changes the work of building software, especially design and product judgment. Trevin describes starting with a value proposition before generating designs, using visual references to guide exploration, and keeping humans involved in critique. His “AI sandwich” puts human attention on defining the work and polishing the result while agents handle implementation.

Concrete examples include illo's character packs for consistent illustrations and Compound Engineering's reviews across model families. Trevin explains why newer models call for clearer goals and fewer prescribed steps, while extensive evaluations, changing model behavior, and outdated plugins make maintenance costly.

The conversation also covers the supervised Hermes Agent setup Trevin built for his daughter, including boundaries around companionship and homework help. It closes with Jev-powered prototypes and Energon, his open source service for sharing documents and files across agents without losing control of the underlying context.

Allen Hutchison is the co-founder and CTO of Vycari, building AI agents for everyday tasks with Chris Perry. He spent 21 years at Google, most recently as a Distinguished Engineer at Google DeepMind, helped found Gemini CLI, and built the Antigravity SDK. His earlier leadership work included Google's mapping products, Core ML, and the AI Developer organization. He writes Letters from Silicon Valley. Dan and Allen discuss why consumer agents need familiar interfaces. Vycari embeds agents in mini apps, including a calendar booking tool that works with meeting preferences and buffer time. Allen wants users to think about the assistant's usefulness rather than the technology behind it. Vycari's two founders have landed well over a thousand PRs in roughly a month. Planning documents guide implementation, nightly jobs keep those documents aligned with code, and review follow-ups become issues that agents can implement. Independent reviews and reflection on user trajectories help identify problems, while Allen retains the final merge decision. Their engineering choices favor quick feedback and manageable costs. Vycari is separating microservices into their own repositories and runs Python and Postgres on VPSs. Allen explains how inexpensive models, stronger models writing their procedures, and deterministic integrations support the goal of a $5 monthly subscription. Full episode notes Transcript Chapters

Cory O'Daniel is CEO and co-founder of Massdriver, an internal developer platform and platform orchestrator for governed self-service infrastructure using Terraform, OpenTofu, and Helm. He has spent more than 20 years building teams and startups and working with cloud infrastructure. He created Bonny, an Elixir-based Kubernetes operator framework, and is a co-founder of OpenTofu. Dan and Cory discuss what infrastructure agents need to act safely. Massdriver models environments and resource relationships so agents can query context directly, while separate agent identities and attribute-based permissions constrain their access. Cory describes a staging workflow that tests infrastructure changes through real deployments before he promotes a release to production. Cory explains how a tested, consistent codebase supports his team's Claude Code workflow, why enforceable tooling matters more than long instruction files, and why human review still matters. He argues that engineers should build quality controls and deployment paths for domain experts who can now create software themselves, with collaboration and operational ownership still needing attention.
