Maria Gorinova: Feedback Loops That Fix Your Codebase
Maria Gorinova: Feedback Loops That Fix Your Codebase Oct 13, 2026 2277 Agent feedback loops are how a software factory maintains itself: agents mining their own session logs, PR comments and production signals, then fixing what they find. Maria Gorinova, member of technical staff at Tessl, explains how to build them, and why vague intent turns a loop into a mess.What we cover:– What a software factory is: repeatable workflows, a shared execution environment and agent
Legora CTO: Why AI Agents Need More Than a Chat Window
Legora CTO: Why AI Agents Need More Than a Chat Window Oct 6, 2026 2662 AI coding agents now write almost all of Legora's code, with engineers running up to ten in parallel. Yet the CTO behind that shift thinks measuring adoption by tokens burned is a mistake. Jacob Lauritzen, CTO of Legora, joins Simon Maple to unpack what actually scales when agents do the typing, and where human judgment still has to stay in charge.What we cover:– How Legora's engineers o
Liz Fong-Jones: 2x the PRs, 1.5x the Incidents
Liz Fong-Jones: 2x the PRs, 1.5x the Incidents Sep 29, 2026 2978 Honeycomb went from 30 to 70 merged pull requests a day in three months. The catch: automated code review, not code generation, became the real bottleneck of software automation. Liz Fong-Jones, Technical Fellow at Honeycomb, explains why incidents still rose 1.5x, how their internal bot Autobot now reviews every PR, and why AI amplifies whatever org you already have.What we cover:– How automated
Dexter Horthy: Why We Stopped Trusting AI to Write the Plan
Dexter Horthy: Why We Stopped Trusting AI to Write the Plan Sep 22, 2026 3372 HumanLayer CEO Dexter Horthy on why his team's bet on spec driven development nearly wrecked their own codebase, and what changed his mind about reviewing AI-written code. Dexter walks through the "YOLO pull request" experiment that ran for months before the codebase became unusable, the "dumb zone" that limits how much context you can hand a model, and why he now believes
AWS's Marc Brooker: Specs, Not Code, Are the Hard Part
AWS's Marc Brooker: Specs, Not Code, Are the Hard Part Sep 16, 2026 3409 Spec-driven development is reshaping what software engineers actually do all day, and Marc Brooker, VP and Distinguished Engineer at AWS, has read 3,000 to 4,000 postmortems that convinced him the code was never the hard part. In this episode of The AI Native Dev, Marc explains why testing and specification are now the real engineering work, why metastable failures keep taking down systems that lo
You Don't Need Juniors to Code. Hire Them Anyway.
You Don't Need Juniors to Code. Hire Them Anyway. Sep 8, 2026 3142 Coding agent reliability isn't a model problem, it's a gates problem. Ran Aroussi, creator of yfinance and founder of Automaze, argues that an "agentic workflow" is a contradiction in terms, and that the only thing standing between you and full autonomy is deciding where a human still signs off. He also thinks you stopped needing junior developers for their coding skills about
850 PRs a Week: How Tessl Runs a Software Factory
850 PRs a Week: How Tessl Runs a Software Factory Sep 2, 2026 3077 The software factory that put up 850 pull requests in a week, with 85 to 90% of them handled by agents end to end. Tessl's Head of Product Dru Knox on how it actually got built, why it started with skills rather than automation, and the two things nobody expects a factory to change. Guy Podjarny digs into the skills-to-loops-to-factory path, and what breaks when you skip a step.What we cover:
Lada Kesseler: I Trust AI Tests Less Than AI Code
Lada Kesseler: I Trust AI Tests Less Than AI Code Aug 25, 2026 2750 Lada Kesseler's approach to loop engineering is brutally simple: give the agent one step, make it write the result to a file, then read it back and go again. She calls it a centrifuge. Spin fast enough and the stupid comes out.The Logic20/20 principal engineer has spent the last year and a half building the ground rules, skills and refinement loops that fight the defaults coding agents ship w
Every Repo Is a Software Factory Now | Don Syme, GitHub
Every Repo Is a Software Factory Now | Don Syme, GitHub Aug 18, 2026 3875 Turning every repo into a software factory sounds like marketing until you see the machinery underneath. Don Syme, Principal Researcher at GitHub, breaks down continuous AI and GitHub Agentic Workflows, now in public preview. The short version: the agents are the easy part, the quality gates and guardrails are the work.Watch Don's AI DevCon Talk here: https://youtu.be/kbvqRWY-bUsWhat we cover
The Background Check You Can't Run on an AI Agent
The Background Check You Can't Run on an AI Agent Aug 11, 2026 2862 The thing that makes an agent useful is the exact thing that makes it dangerous. Keycard co-founder Ian Livingstone breaks down why non-determinism is both the feature and the bug, and why identity, not model quality, is what really gates how much autonomy you can hand an agent. If you have ever clicked "always allow" without reading it, this one is about you.What we cover:– Why authenti
Datadog Deleted All Its AI Context. It Worked.
Datadog Deleted All Its AI Context. It Worked. Aug 4, 2026 3683 Datadog's Language Foundations team deleted an entire folder of AI context files that had been carefully written and maintained for over a year, expecting a performance hit. Instead, their evals got better. Simon Boudrias, who runs Language Foundations at Datadog, walks Guy through what that taught his team about context rot, and the full journey of scaling AI coding agents to 4,000 engineers
Inside the Dark Factory: AI That Ships Code Solo
Inside the Dark Factory: AI That Ships Code Solo Jul 28, 2026 3518 At Tessl, 95% of the code shipped by their internal "Dark Factory" has never been looked at by a human, and the team still ships hundreds of pull requests a week, including through entire weekends. Rob Willoughby, who leads AI engineering at Tessl, joins Simon to open up the hood on how it actually works: the orchestrator, the verification layers, and the failures that forced the team to
