    Inside the Dark Factory: AI That Ships Code Solo

    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 – The queue bug that took dozens of pull requests to fix, and the from-scratch Elixir rewrite that stress-tested the whole system – How to start building your own software factory, one verification layer at a time Chapters: 00:00:00 - Introduction 00:01:44 - Rob Willoughby joins: Tessl's PR numbers 00:04:01 - Live demo: kicking off two pull requests 00:14:03 - Building the Dark Factory: orchestrator vs. context 00:19:01 - Code review layers: Code Rabbit, Tessl Change Verify, and verifiers 00:29:58 - Earning trust: accountability in an autonomous system 00:33:20 - What broke: the queue bug and the Elixir rewrite experiment 00:39:56 - Onboarding new engineers into the factory 00:42:58 - Advice for teams starting their own software factory 00:52:03 - Back to the demo, and the road to 100% adoption 🌐 Tessl: https://tessl.io 🔔 Subscribe for weekly episodes on AI-native development What would your own verification layer catch, and where would it break?

    From Living Room Hack to 30 AI Agents at Cyera

    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 Chapters: 00:00:00 - Introduction 00:02:04 - Meet Ori Shoshan and what Cyera does 00:06:50 - The living-room spark: why Ori built his own agent 00:11:09 - Whitelisting tools instead of blacklisting them 00:12:55 - Why every claim needs a citation 00:15:35 - Reducing hallucinations with clean-context verification 00:21:04 - Taking Borg to Slack: the first agents at work 00:25:33 - Why naming your agent drives adoption 00:39:53 - Knowledge graphs over RAG 00:52:00 - The AI Captains: scaling adoption with carrots, not sticks 🌐 Tessl: https://tessl.io 🔔 Subscribe for weekly episodes on AI-native development Have you built guardrails like this into your own agents?

    Inside Anthropic: How Claude Tag Is Changing Agentic Work

    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 Watch Lamis' talk from AI Native DevCon London 2026 here: https://youtu.be/tTcxVv8HHNw Chapters: 00:00:00 - Introduction 00:01:46 - Meet Lamis Mukta from Anthropic 00:02:56 - What is Claude Tag? 00:10:07 - From single-player to multiplayer agentic coding 00:15:50 - Trust, capability, and the METR chart 00:21:02 - How the industry is really using Claude Code 00:26:33 - The Claude Code origin story 00:33:47 - Agent identities and permissioning at scale 00:40:23 - Claude beyond engineering at Anthropic 00:48:16 - Dreaming and practical tips for rolling out Claude Tag 🌐 Tessl: https://tessl.io 🔔 Subscribe for weekly episodes on AI-native development What's the one thing your team would delegate to an AI teammate first?

    The Tessl Agent: Build Your Software Factory on Autopilot

    What if the whole point of your AI agent was to eventually make itself redundant? Dru Knox, Head of Product at Tessl, introduces the Tessl agent — a new interface built not just for AI-assisted coding, but for building the software factory that keeps improving without constant human input. This is a conversation about loop engineering: how to set up automated feedback cycles so your agents get smarter, your code review gets tighter, and your team ships more without adding more toil. What we cover: – What the Tessl agent is and how it fits into the broader Tessl platform – Loop engineering: why building automated feedback loops is the right place to start – How the agent sets up and continuously improves agentic code review – Why optimising your AI agent costs is usually the wrong lever to pull – The case for open, modular software factories — and the risk of vendor lock-in – UX expectations in the AI era: why outcome-oriented interfaces are now the baseline 🌐 Tessl: https://tessl.io 🔔 Subscribe for weekly episodes on AI-native development What's your approach to building feedback loops into your agent workflows? Drop a comment — we'd love to hear how teams are thinking about this.

    Why Agents Are Forcing Enterprises to Finally Fix Their Dev Process

    Enterprises are finally being forced to care about their software development lifecycle — not because anyone suddenly got disciplined, but because agents cost money and the waste is now visible. When it was humans, it was "Timmy's just lazy." Now it's a line item.  Simon Maple sat down with Patrick Debois (the godfather of DevOps, now DevRel at Tessl), Tammuz Dubnov (co-founder and CEO of Autonomy AI), and Daniel Jones (Head of Product at re:cinq) at AI Native DevCon London for a wide-ranging panel on AI enablement — who owns it, what's breaking, and what the organisations getting it right are actually doing differently.  What we cover:  – Who should own agentic coding adoption inside an enterprise, and why platform teams are already filling the vacuum  – The "Timmy's lazy" problem: why agent cost visibility is forcing process discipline that humans never got  – Why PR-based workflows are an anti-pattern inside enterprises once you're moving at agent speed  – The PUMP framework (Plan, merge, polish): how one team is shipping features with developers, PMs, and designers all opening PRs –  Rethinking what a "test" is in an agentic world — and why feedback loops matter more than first-pass correctness  – The biggest mistake enterprises are making right now: piecemeal adoption with no mandate and no shared tooling   🌐 Tessl: https://tessl.io  🔔 Subscribe for weekly episodes on AI-native development  What's your team's approach to AI enablement — central mandate or letting individuals find their own way?
