    Design Docs, Nightly Audits, and Vycari's Agent Development Loop

    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.

    Why AI Can Generate a Song but Struggles with Music Theory

    Ben Morss is a Developer Advocate at Mistral. He previously spent 9.5 years at Google as a Product Manager for advanced APIs in Chrome and a Developer Advocate for the web. He earned a bachelor's degree in Computer Science and Music from Harvard University and a doctorate in Music Composition from the University of California at Davis. He continues to make music and write about music theory. Dan and Ben discuss how LLMs help people learn while still missing context and intent. Their discussion of information theory and training data leads into a debate about software craft when agents make code much cheaper to produce. Ben describes Chat Invaders, a cat-themed demo game, and a reunion sing-along app that broke with forty people present. He had not load-tested the app and did not determine what caused the failure. They explore why working output does not guarantee value for a business or an audience. Ben wants musical assistance that can develop ideas and handle arranging work, but finds music theory explanations unreliable. The conversation ends with the human experience behind fiction and songs, and open questions about whether models could be conscious.

    Agents, Engineers, and Citizen Developers

    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.

    Building a Software Factory with Gas City

    Stephanie Jarmak is an AI Engineer at Omni working on multi-agent orchestration and code intelligence. She is a research affiliate for NASA's Science Explorer (SciX) and a maintainer of Gas City, an open-source orchestration builder for multi-agent coding workflows. Dan and Stephanie discuss how she became a Gas City maintainer by learning from review agents, encoding contribution standards in skills, and building an issue-triage workflow. Automating those steps exposed new reliability problems, from failures across dependencies to excessive alerts and agents that overreact to hypothetical risks. Their conversation connects these experiments to Stephanie's move from planetary science into search and AI engineering. They examine the appeal of building with agents, the responsibility for maintaining what those agents produce, and the mixed emotions of seeing models solve once-difficult research tasks. Personal game projects and Omni's approach to shaping her role show how her curiosity carries across both work and home.

    Agentic Data Science in a Reproducible Marimo Notebook

    Eric Ma is a Senior Principal Data Scientist at Moderna, where he leads the Data Science and Artificial Intelligence (Research) team. Previously, he conducted biomedical data science research at the Novartis Institutes for Biomedical Research and earned his doctorate in Biological Engineering from MIT. Eric is also an open-source software developer known for leading pyjanitor and nxviz and contributing to NetworkX and PyMC. Dan and Eric discuss Eric's rapidly changing practice of agentic data science, centered on Marimo Pair and reproducible Python notebooks. Eric demonstrates an analysis of protein activity and stereoselectivity data, explains why canonical sources and inline environment metadata matter, and shows how agents make ambitious custom visualizations more approachable even when a live demo fails. The conversation then turns to design documents, testable specifications, repository conventions, and the attention-management practices Eric uses to keep agent work from becoming a context-switching trap.

    AI Agents for Bayesian Data Science

    Thomas Wiecki, Founder, PyMC Labs, is the author of PyMC, one of the most popular frameworks for Bayesian modeling, and the founder of PyMC Labs, a Bayesian AI consultancy. He holds a PhD in Computational Cognitive Neuroscience from Brown University and previously served as VP of Data Science and Head of Research at Quantopian Inc., where he built and led a team of data scientists to develop a hedge fund leveraging insights from a crowd-sourced pool of 300,000 researchers. In this episode, we explore how AI agents have made Bayesian methods more accessible to non-experts. Bayesian models are useful for both forecasting and decision-making under uncertainty. These models can act as scenario simulators, making it possible to ask what-if questions about marketing, seasonality, or health interventions while exposing the mechanisms behind an outcome. We also discuss how agentic engineering has finally helped deliver on some of the original promises of data science, how to effectively embedding agents in tools like Slack or Discord to democratize access to company information, and what parts of data science still require talking with humans to understand the problem. Full episode notes Transcript Chapters (00:00) - Agentic engineering meets Bayesian decision science (05:27) - Bayesian models versus black-box prediction (10:22) - Confounders and causal mechanisms (12:41) - From notebooks to model-aware agents (15:41) - The rise of agentic interfaces (19:18) - Alchemize and verified code translation (29:49) - Agentic data science beyond the silo (34:25) - Daimon and collaborative multiplayer AI (37:43) - Verification and unsettled methods (42:53) - Parallel agents and PyMC Forecast (51:08) - The Bayesian method of software engineering (53:59) - Agents as software's primary users (57:08) - Institutional knowledge and bus-factor risk (01:03:56) - Faster research and open source (01:12:05) - Causal models for AI's future ⠀ Links from the show -------------------- Master Agentic Data ScienceShow Us Your Agent SkillsPyMCPyMC LabsBayesian modelingcausal questionsmedia mix modelingDaimonAlchemizePyMC Forecastprior data fitted networksNumPyro ForecastStanJAXPyTorch⠀ Guests ------- Thomas Wiecki, Founder, PyMC Labs WebsiteLinkedInGitHubTwitter⠀ Follow the podcast ------------------- LinkedInThreadsInstagramTikTok⠀ Follow Dan Gerlanc ------------------- XLinkedInThreadsBluesky
