The AI Native Dev - from Copilot today to AI Native Software Development tomorrow

Agentic coding has outgrown the text box. Maggie Appleton, staff research engineer at GitHub Next, argues that walls of CLI output and AGENTS.md files serve coding agents far better than the humans steering them. She walks through Chopin, the GitHub Next prototype where background agents turn a team's planning chat into a structured plan, and makes the case for agents that prompt you instead of waiting to be prompted.

What we cover:
– Why text-heavy agentic coding tools favor agents over humans
– Boundary objects: what AGENTS.md, skill files and MCP servers get right and wrong
– Multiplayer planning with coding agents in GitHub Next's Chopin
– Human-to-agent handoffs, formal verification and spec-driven development
– Why software quality is rising, not falling, with coding agents
– Which roles still matter: PMs, designers and engineers

AI attackers now move at machine speed, while most security teams still move at meeting speed. Former Robinhood CSO Caleb Sima has seen an AI attacker up close, and he argues the only way to keep up is to take humans out of the defense loop.

Caleb joins Guy Podjarny to unpack what changes when the attacker is an agent: one that hits every surface at once, reverses open-source code to find a 0-day, and once inside, burns your own AI tokens to keep going.

What we cover:
– Why AI attackers outran the red teamers' predictions, including 400 Linux 0-days found at 2.5 hours each
– Whether sandboxes can contain AI agents, and why external monitoring matters
– Who is accountable when your AI agent hacks someone else
– What actually changes when an AI attacker gets inside your company
– Deception, digital twins and forensic-grade detection
– Automating security: instant patching, one-way vs two-way doors, and security teams that ship the fix

Your coding agent should never hold a credential, and in a software factory that rule is only the start. Recorded live at the AI Security Summit in San Francisco, Simon Maple sits down with Eli Aleyner (Docker), Marcelo Sousa (Snyk) and Ian Livingstone (Keycard), co-authors of Agent Baseline, a security reference architecture for the AI software factory.

The panel unpacks why agents have to be treated as fundamentally unpredictable actors, why sandboxing alone is not enough when skills and MCP servers make the supply chain dynamic, and why approval prompts collapse into fatigue. Marcelo's verdict: sometimes these are kids with chainsaws.

What we cover:
– The three levels of autonomy, from coding agents to fully agent-directed workflows
– Sandboxing coding agents and injecting secrets at the egress point
– Why the agent supply chain is dynamic: skills, MCP servers and cloned repos
– Prompt injection, least privilege and agents monitoring other agents in the harness
– Approval fatigue: YOLO mode vs CYA mode
– Where to start securing your software factory on Monday morning

Which level of the software factory are you at today, and what are you locking down first? Tell us in the comments.

Skills and MCP servers are the new npm, and AI coding agents are pulling them into enterprise codebases faster than security can keep up. Manoj Nair, Chief Innovation Officer at Snyk, joins Guy Podjarny at the Snyk AI Security Summit to map where enterprise agentic coding really stands.

They get into why a 50,000-agent Claude Code rollout was pulled forward by weeks, why the autonomous attacker has some CISOs ready to accept an outage to patch faster, and how security is moving into the agent loop of the software factory.

What we cover:
– Why leadership and culture, not tooling, decide how fast enterprises adopt AI coding agents
– The three risks of agentic coding: insecure output, the skills and MCP server supply chain, and agent behavior
– Running coding agents locked down: sandboxes, agent identities and no open internet
– Who owns the code an agent writes, and why AI-native organizations treat it as shared risk
– Securing the software factory: security context in the agent loop and agentic remediation of the backlog
– What still has to be solved before enterprises trust agents: identity, intent and behavior

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 feedback loops
– Why agent context alone isn't enough, and where harness engineering comes in
– The three stages of a feedback loop: analyze a data stream, find the problem, request the fix
– Inner, middle and outer loops, from verifiers on every PR to self-healing in production
– How Tessl's "comment diet" loop catches drift that no single PR causes
– Operators and stewards: the human roles in a software factory

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 orchestrate many AI coding agents at once, from shared local dev resources to cloud agent setups
– An agentic loop that reproduces, fixes and tests bugs straight from Slack
– Why token maxing is a bad way to drive AI adoption, and what to measure instead
– Agent evaluation: regression testing the harness as models and prompts change every week
– Decision models, the verifier's rule, and where autonomy ends and human judgment begins

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 code review lets humans focus on design, not trivial bugs
– Using a decision model like Jev to decide which PRs are safe to auto-merge
– What makes a codebase ready for AI coding agents
– When to trust AI agents with production incidents, and when they're just throwing darts
– Why "Claude did it" isn't an excuse, and what ownership means with AI
– How open source maintainers can handle a flood of AI slop pull requests

Is your team's review capacity keeping up with your AI coding agents? Tell us in the comments.

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 there will always be alpha in reviewing something.

What we cover:
– How HumanLayer's "read the plan, skip the code" experiment quietly broke their own codebase
– Why context windows have a "dumb zone," and what that means for context engineering
– Sean Grove's idea that specs, not code, are becoming the durable artifact
– Building overnight agents that review and fix code before a human ever sees it
– Why treating software development like a factory changes how bugs compound
– What Dexter thinks his advice on reviewing AI-written code will look like in 12 months

Where do you land on the determinism-to-adaptability slider — plan tightly, or let the agent run? Tell us in the comments.

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 look perfectly healthy, and why he still won't let AI write a single word of his blog.

What we cover:
– Why spec-driven development is turning testing into the hardest part of software
– What metastable failures are, and why they keep taking healthy-looking systems down
– How agentic coding tools can learn from postmortems and build their own memory
– Why classic authorization breaks down once you're writing agentic policy
– Why Marc won't let AI write his blog, but is fully comfortable with AI-generated code
– What it takes to bring junior engineers up to speed in an AI-native industry

Do you trust an agent to run its own on-call rotation yet? Tell us in the comments.

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 a year ago, and that hiring them anyway is the only way the industry gets its next generation of architects.

What we cover:
– Why "agentic workflow" is a contradiction, and when agentic coding is the wrong tool for the job
– Where a human still has to sign off, and what coding agent reliability actually depends on
– What a software factory changed about delivery times, pricing and the client backlog
– Why you no longer need juniors for their coding skills, and why you should hire them anyway
– Teachable knowledge vs earned knowledge, and the experience agents cannot compress
– The law firm model: why dev agencies may end up looking more like Kirkland & Ellis than a SaaS startup

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:
– What a software factory actually is, and how it differs from a pile of disconnected automations
– Loop engineering: turning a skill into something that gets better every time it runs
– Why context engineering has to come before automation, and what stalls when it doesn't
– The two gains nobody forecasts from extra agent capacity: quality and fungibility
– Verifiers and evals, or how you enforce a standard that agents are free to ignore
– Context-driven code review, and why a general-purpose reviewer plateaus

If you've hit the plateau Dru describes, tell us where it stopped compounding for you.

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 with, starting with an instruction to stop trying to please her. Along the way she explains why she trusts AI-written tests less than AI-written code, why the description field in an agent skill was never meant for humans, and why most teams chasing a software factory are about to drown in garbage.

What we cover:
– Why agent ground rules have to give the model a mission to disagree with you
– The refinement loop that gets to quality when the first attempt never does
– Why an agent harness only works if it does one thing at a time
– Sketch prototypes: replacing your code with a markdown file and an agent
– Why AI-generated tests are more dangerous than AI-generated code
– Software factories, and what happens when you try to switch into one overnight

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-bUs

What we cover:
– What continuous AI is, and why it sits beside CI/CD rather than inside it
– Why bounding the context is what stops automated agents going off the rails
– Whether the repo is really the right unit for a software factory, and where monorepos break it
– One workflow or an agent zoo? Cost control, scheduling and model exams
– Quality gates, human review, and equipping the reviewer instead of drowning them

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 authentication was enough in the cloud era and stops being enough with agents
– The background check you can't run on an agent, and what has to replace it
– Mission identity: who is acting, on whose behalf, and for what purpose
– Cross App Access, Agent Auth and the protocols trying to fix OAuth
– Consent fatigue, LLM as a judge, and where hard boundaries still belong

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 rebuild trust from scratch.

What we cover:
– How Tessl routes 65-70% of its own pull requests through an autonomous "Dark Factory"
– Why context in the repo matters more to output quality than which model you use
– How natural language "verifiers" turn code review taste into fast, cheap checks agents can pass or fail

What's the riskiest skill you've installed without checking it first? Let us know in the comments.

An engineer builds an AI agent to manage his own life, decides an unrestricted "does everything" agent is too dangerous to trust, and ends up creating the internal agent platform that now runs 30 agents across his entire company.

Ori Shoshan, tech lead at Cyera, walks through the guardrails, citation system, and knowledge graph that turned "let the agent do anything" into "let the agent do exactly what it's supposed to, and nothing else."

What we cover:
– Why one engineer built his own AI agent in his living room, and how it grew into Cyera's internal agent platform
– Whitelisting tools instead of blacklisting them, plus the "escape hatch" that keeps agents honest
– Backing every claim with a citation and using a second model to catch hallucinations before they reach a human
– Trading RAG for a knowledge graph the agent can walk like a wiki
– Turning "use this platform" into "build your own agent" to drive adoption across an entire engineering org
– Running agents on confidential data that can investigate everything but can only ever say what's been cleared

After DevOps, Patrick Debois has a new map. The godfather of DevOps returns to walk through his AI patterns research: how he tracks where AI-native development is heading by mining social signals instead of surveys, why the stack is settling into patterns worth learning, and why your AI budget problem is really an optimization problem.

What we cover:
– Inside the AI patterns site at Tessl.io/patterns and how it's auto-generated
– The four layers of AI enablement: agent, team, platform, and organization
– Solo, shared, and multiplayer modes: the compounding effect of shared context
– Managing agent costs: budgets as a forcing function for optimization
– Scaling adoption: find the success story, don't fight the skeptics
– Hiring system thinkers instead of elegant coders

Six people reacted to Boris's side-project Slack post. A year later, Claude Code is ubiquitous, and the company just launched its next evolution: Claude Tag, an AI teammate that lives in Slack.

Lamis Mukta, Member of Technical Staff at Anthropic, joins Simon Maple to unpack how Claude Tag works, why Anthropic built it, and what it took internally to go from a scrappy side project to a company-wide habit.

What we cover:
– What Claude Tag actually is, and how it differs from Claude Code and Cowork
– Why trust in AI agents is really a function of model capability, not just comfort
– The internal "dogfooding" culture that shaped Claude Code and Claude Tag
– How Anthropic secures multiplayer AI with agent identities and channel-level permissioning
– Where Claude and Claude Tag show up outside of engineering at Anthropic
– Dreaming: how Anthropic's managed agents continually improve their own memory
