AI Security & the Agent-Ready Web: Experts Weigh In

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?

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 [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?

BONUS: DevCon London: Real Talk on AI ROI, Harnesses & Evals

From the expo floor of AI Native DevCon London, Simon Maple went straight to the developers — speakers, attendees, and sponsors — to ask what's actually working with AI in 2026. The verdict? Outcomes beat outputs every time, 4,000-hour workloads are collapsing to 20 minutes, and the real bottleneck isn't code. This is a conference floor walkthrough: honest, unscripted takes on harness engineering, evals, AI adoption mindsets, and the change management challenge that nobody talks about enough. What we cover: – Why measuring token usage, code commits, and outputs will lead your team astray – How NearForm cut a 4,000-hour AML backlog to 20 minutes using agents – Harness engineering and evals as the developer skills that matter most in 2026 – Why change management — not tooling — is the missing ingredient for real AI ROI – How AutonomyAI is letting PMs and designers ship directly to production Chapters: 00:00:00 - Welcome to AI Native DevCon London 00:01:03 - Chris Baty: Outcomes Over Outputs 00:05:15 - Martin: How Tooling Changed Everything 00:07:21 - Ryan: Harnesses, Evals and Skills 00:08:50 - Manny Saka: Plan Before You Prompt 00:11:58 - Cian O Maidin, NearForm: Real AI ROI 00:15:21 - Snyk: Building Trust at Scale 00:17:01 - AutonomyAI: Shipping Without Engineering 00:21:35 - Tessl Agent: Harness Engineering 00:22:41 - Closing Thoughts 🌐 Tessl: https://tessl.io 🔔 Subscribe for weekly episodes on AI-native development Whether you're cautious or YOLOing it with AI — drop where you land in the comments.

AI Security & the Agent-Ready Web: Experts Weigh In

What does it mean to build securely when agents can negotiate their own guardrails? And what happens to the web — CLIs, frameworks, even the browser itself — when the primary user is no longer human? At AI Native DevCon London, Simon Maple sat down with two panels of experts to find out.  First: a security roundtable with Joseph Katsioloudes from GitHub, Liran Tal from Snyk, and John Groetzinger from Cisco.  Then: a web AI conversation with Dana Lawson from Netlify, Maximiliano Firtman from codemia, and James Moss from Tessl.  What we cover:  – Why 83% of enterprises plan to deploy AI but only 29% feel ready to do so securely  – Prompt injection as a risk you have to accept — and how least privilege and sandboxing are your real defences  – The "agent experience" concept: why systems built for human eyes fail at machine scale  – Whether fundamentals like HTTP, semantic HTML, and accessibility still matter when agents do the heavy lifting  – How WebMCP lets websites expose tools directly to agents  — and why blocking them is like trying to turn off the sun Join the AI Native Dev Community on Discord: https://tessl.co/4ghikjh Ask us questions: podcast@tessl.io
