Doctrine engineering, supervision trees, and the operating model underneath. en-us noreply@dangrafham.com (Dan Grafham) noreply@dangrafham.com (Dan Grafham) https://dangrafham.com/supervisor-tier https://dangrafham.com/supervisor-tier Thu, 21 May 2026 12:00:00 +0000 Dan Grafham Most agent systems bubble every failure up to a human supervisor at the top of the stack. Erlang solved this in 1986. EVE Online re-derived it for 1000-pilot battles in 2008. The agent layer is the third domain to need the pattern. The novelty is the port. https://dangrafham.com/prompt-injection-privilege-problem https://dangrafham.com/prompt-injection-privilege-problem Thu, 21 May 2026 10:00:00 +0000 Dan Grafham Most current prompt-injection mitigation is security theater. Software security solved the same kind of bug class structurally in 1995. The agent industry is repeating the wrong path, and the structural answer is the same: make the dangerous path not exist. https://dangrafham.com/pixel-pushing-trap https://dangrafham.com/pixel-pushing-trap Tue, 19 May 2026 12:00:00 +0000 Dan Grafham AI makes it easy to build more. You need to make sure you're building the right things. Why frictionless implementation aims the factory at cosmetics while the business engine sits unwritten, and the four disciplines that hold the line. https://dangrafham.com/b2a-business-to-agent https://dangrafham.com/b2a-business-to-agent Tue, 19 May 2026 08:00:00 +0000 Dan Grafham The third distribution model after B2B and B2C. Your customers are AI agents finding you before a human ever sees your URL. MCP is the new SEO, and the conversion funnel is a JSON schema. https://dangrafham.com/doctrine-bifurcation https://dangrafham.com/doctrine-bifurcation Mon, 18 May 2026 12:00:00 +0000 Dan Grafham The deeper structure under Doctrine Engineering: why the rules split into two registers (the ones the runtime enforces and the ones agents read), and why that split is what makes audit-by-construction enforceable rather than aspirational. https://dangrafham.com/doctrine-engineering https://dangrafham.com/doctrine-engineering Sun, 17 May 2026 12:00:00 +0000 Dan Grafham Prompt engineering scales to one agent. Doctrine engineering scales to one hundred. The next discipline, the practice that emerges when probabilistic compliance breaks at scale, and why the term-of-art slot is open right now. https://dangrafham.com/shipping-paralysis https://dangrafham.com/shipping-paralysis Fri, 08 May 2026 12:00:00 +0000 Dan Grafham Why AI making code free didn't make shipping easier, and the specific traps that keep a genuinely good project permanently local. https://dangrafham.com/ai-debt https://dangrafham.com/ai-debt Sat, 25 Apr 2026 12:00:00 +0000 Dan Grafham What happens when the framework starts serving itself instead of shipping the product. Distinct from technical debt; AI Debt lives in the prose, scaffolding, and meta-process around the code. https://dangrafham.com/humans-moving-upchain https://dangrafham.com/humans-moving-upchain Mon, 20 Apr 2026 12:00:00 +0000 Dan Grafham The substrate-level shift that the entire AI moment is producing. Agents move in below. Humans relocate above. https://dangrafham.com/cambrian-explosion-of-software https://dangrafham.com/cambrian-explosion-of-software Wed, 15 Apr 2026 12:00:00 +0000 Dan Grafham Software was stuck single-celled for fifty years. AI is the oxygen. Why every software category is about to be re-founded, and how to tell which game you're playing. https://dangrafham.com/level-5-dark-factory https://dangrafham.com/level-5-dark-factory Wed, 08 Apr 2026 12:00:00 +0000 Dan Grafham A deep dive into Level 5: what it actually requires, what it looks like in practice, and what kind of person could architect one. https://dangrafham.com/five-levels-of-ai-programming https://dangrafham.com/five-levels-of-ai-programming Fri, 03 Apr 2026 12:00:00 +0000 Dan Grafham A working framework for the current state of AI-assisted development, and a clear map of where the industry is heading.
