TL; DR: Vibe Coding Best Practices — Food for Agile Thought #538
Welcome to the 538th edition of the Food for Agile Thought newsletter, shared with 35,647 peers. This week, Teresa Torres shows non-engineers how to embrace vibe coding best practices, for example, by upfront Markdown planning and a separate review agent, while Ethan Mollick identifies interface design, not model capability, as AI’s real bottleneck. Lenny Rachitsky interviews Simon Willison on why November 2025 marks AI’s inflection point and why mid-career engineers face the greatest displacement risk. David Pereira and Jason Knight, Janna Bastow, and Saeed Khan all warn that product managers lean on AI to ship faster while abandoning discovery and strategy, and Maarten Dalmijn reminds us that deliberately chosen constraints are what make great products possible.
Next, Martin Eriksson warns that strategy drift is silent, with executives believing they are 82% aligned, while actual alignment sits at just 23%, and Kyle Poyar adds that AI agents are becoming B2B buyers who will actively disqualify products with opaque pricing and “contact sales” CTAs. Viktor Cessan argues that LLMs are exposing large codebases and headcounts as liabilities. Also, Jack Dorsey, Roelof Botha, and Joost Minnaar each propose that AI makes traditional hierarchies obsolete in favor of small, autonomous, radically transparent teams. Jeff Gothelf rounds things out by offering a four-dimensional rubric to make product judgment visible and teachable as AI collapses execution costs.
Lastly, Nate Herk extracts eight practical insights from the leaked Claude Code source code, from hidden slash commands to multi-agent architecture, and Sachin Rekhi outlines ten AI-powered discovery workflows that accelerate customer research without replacing human judgment. Janelle Teng sees Physical AI approaching an inflection point as six catalysts converge, and Tristan Kromer frames the gap between AI deployment and business impact as a practice problem, mapping six maturity levels from passive consumer to multi-agent architect. Finally, Tracy St.Dic shows how Zapier has already operationalized that shift by raising its hiring bar to require embedded AI use and provable adoption leadership.
