<hr /> When I spun a <a target="_blank" rel="noopener noreferrer" href="https://podcasts.apple.com/us/podcast/a-tale-of-two-phils-exploring-umbracos-open/id1801794414?i=1000749874476">“Tale of Two Phils”</a> on an episode of <a target="_blank" rel="noopener noreferrer" href="https://podcasts.apple.com/us/podcast/cms-critic-the-critics-corner-podcast/id1801794414">The Critic’s Corner Podcast</a> earlier this year, I wasn’t prepared for how complementary my two guests would sound. If you listen to the conversation, there are multiple such intersections between <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/products/umbraco">Umbraco</a> CTO <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/in/filipbech/">Filip Bech-Larsen</a> and Staff Engineer (and resident AI guru) <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/in/phil-whittaker-82481716/">Phil Whitaker</a><a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/in/filipbech/">.</a> In many ways, the two complete each other, handing off thoughts like an MCP server connecting the dots. It elevated the knowledge on multiple levels.This makes the collaboration a solid one for Umbraco, an open source CMS that continues to diligently push forward on its agentic AI ambitions. The company’s steady pace of innovation just took another leap forward with the launch of new Backoffice Extension Skills, which are based on Anthropic’s <a target="_blank" rel="noopener noreferrer" href="https://resources.anthropic.com/hubfs/The-Complete-Guide-to-Building-Skill-for-Claude.pdf">Agent Skills</a>. <figure class="image image_resized" style="width:32.52%"><img src="https://cmscritic.com/ms-content/uploads/2026/04/phil-whittaker-2.jpg" alt="" /></figure>Umbraco Staff Engineer (AI) Phil Whitaker “We’re seeing a fundamental shift in how digital projects are delivered,” Whitaker said, driving home the key advantages of these new additions to Umbraco. “AI is becoming the starting point for new projects and is where developers explore ideas. Backoffice Extension Skills ensure that when your team uses an AI assistant, the correct Umbraco knowledge is available.”<img /><figure class="image image_resized" style="width:80.99%"><img src="https://cmscritic.com/ms-content/uploads/2026/04/umbraco-ai-platform-winter-2026.png" alt="" /></figure>Source: Umbraco Winter Keynote 2026 Umbraco’s aggressive AI product horizon was teased during its <a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=GK-eGhzZYpw">Winter Keynote in February,</a> and several digital agency partners are experimenting with creating AI-based workflows. This includes some strong use cases, such as <a target="_blank" rel="noopener noreferrer" href="https://digitalwonderlab.com/umbraco-agency/umbraco-lab-notes/alt-text-shouldnt-be-this-hard-so-we-fixed-it/">Digital Wonderlab’s automated Alt Text generator</a> for improving website accessibility.<h3 id="what-are-agent-skills?-">What are Agent Skills? </h3>In a nutshell, Anthopic’s Agent Skills are like “onboarding guides” that enable AI to execute specific, complex workflows – like data analysis or file creation – without overloading its context window. Agent Skills provide modular, reusable, and organized packages that contain instructions and scripts that help developers and users build, share, and deploy agents that are more effective and context-aware.Anthropic launched Agent Skills as an open standard in December 2025 under <a target="_blank" rel="noopener noreferrer" href="https://www.linuxfoundation.org/">The Linux Foundation.</a> Since then, they’ve been widely adopted, working across Claude and other AI platforms.<h3 id="maintaining-control-and-extensibility">Maintaining control and extensibility</h3>Umbraco’s Backoffice Extension Skills are like a roadmap for AI agents, guiding them to the most up-to-date Umbraco documentation, examples, and source code. Skills are exposed using a standardized endpoint that can be called by AI tools like <a target="_blank" rel="noopener noreferrer" href="https://claude.ai/">Claude</a>, <a target="_blank" rel="noopener noreferrer" href="https://chatgpt.com/">ChatGPT</a>, or custom <a target="_blank" rel="noopener noreferrer" href="https://www.langchain.com/langchain">LangChain agents</a> – making it incredibly extensible.With this guidance, LLMs and agents use the most current version of the Umbraco software and the essential modern frameworks – where they can effectively customize the backoffice or complete tasks like building dashboards or property editors. All of Umbraco’s Backoffice Extension points are registered, documented, and supported, ensuring that customizations are maintained.According to Filip Bech-Larsen, Umbraco’s Backoffice Extension Skills are the first series of skills, aimed at supporting developers using AI agents for building and extending their digital projects. <figure class="image image_resized" style="width:32.75%"><img src="https://cmscritic.com/ms-content/uploads/2026/04/filip-bech-larsen-1777422652939.jpg" alt="" /></figure>Umbraco CTO Filip Bech-Larsen “Agent Skills mirror the way that Umbraco’s Backoffice Extension points work,” he added. “Each Backoffice Extension point links AI Skills to the latest Umbraco documentation, source code, and examples. This supports safer development and positions Umbraco as one of the first major CMS platforms to deliver a comprehensive, agent-ready architecture.”Ready to level up your skills? <a target="_blank" rel="noopener noreferrer" href="https://umbraco.com/blog/the-agent-ready-cms-introducing-agent-skills-umbraco-backoffice-extension/">Learn more here.</a><h3 id="building-on-an-agentic-ai-foundation">Building on an agentic AI foundation</h3>The proof is in the pudding, as they say – and Umbraco’s partners are putting its growing AI capabilities to work. Several use cases are nominated for the <a target="_blank" rel="noopener noreferrer" href="https://codegarden.umbraco.com/awards/">Umbraco Awards</a> at the upcoming <a target="_blank" rel="noopener noreferrer" href="https://codegarden.umbraco.com/">Codegarden 2026,</a> which is being held June 10-11 in Copenhagen. Case in point: <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/in/dennis-adolfi/">Dennis Adolfi</a>, head of technology at <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/knowit-experience/">Knowit Experience,</a> a leading digital agency based in the Nordics, recently shared an innovative agentic solution for <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/company/bewigroup/">BEWI Group.</a> In the use case, agents assist or fully manage complete workflows in the dev cycle, from design to code to deployment – even through content creation. The solution relies on <a target="_blank" rel="noopener noreferrer" href="http://umbraco.ai/">Umbraco.AI</a> and Umbraco’s MCP to deliver transformative results, the kind that have earned Knowit a nomination for Umbraco’s Best Innovation with AI Award. “[Umbraco] really is a CMS built for AI,” Adolfi said. Another contender for this category comes from <a target="_blank" rel="noopener noreferrer" href="https://www.perplex.nl/en/">Perplex Digital</a>, which developed an AI-powered solution for <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/company/autolease-van-centraal-beheer/">Autolease van Centraal Beheer,</a> allowing users to literally “talk” to their website. The agency replaced the company’s static navigation with conversation, making it easier for customers to use the site when they’re unable to manually browse for information. They can fill out forms simply by using their voice, making the company’s services more accessible. <a target="_blank" rel="noopener noreferrer" href="https://nxtds.com">NXT Digital Solutions Ltd </a>is also nominated for a dynamic CMS migration project for <a target="_blank" rel="noopener noreferrer" href="https://www.exclusive-networks.com/">Exclusive Networks</a>. NXT introduced Umbraco's Backoffice Agents to automate content tagging, publishing pipelines, and version control to resolve critical indexing failures that were affecting over 1,300 pages – making content more discoverable to search engines and users.<h3 id="why-it-matters">Why it matters</h3>Umbraco continues to introduce high-value tooling for its AI capabilities, and the alignment with Anthropic's Agent Skills is a sage move. By embedding an agent-ready architecture directly into its flexible and extensible CMS, it's moving beyond bolt-on assistants to guided, governed solutions – the kind that provide solid ground for faster and safer agent performance. As is evidenced by the use cases above, it's clear that Umbraco's partners are proving out the potential for how AI and agents can be successfully applied. My bet is that the “Two Phils” are seeing some innovative outcomes they weren't even anticipating. And I'm sure they would agree that's a good thing. <hr /><h3 id="upcoming-events">Upcoming Events</h3> <img style="width:34.15%" src="https://cmscritic.com/ms-content/uploads/2026/01/logo_jday_hor.png" /><h4 id="joomladay-usa-2026"><a target="_blank" rel="noopener noreferrer" href="https://www.jdayusa.com/">JoomlaDay USA 2026</a></h4>April 29 - May 2, 2026 – Delray Beach, FloridaBe part of the Joomla community in one of the most iconic cities in the world!
