Anthropic's Agent Skills sound like a powerful new AI capability, but the reality is far more low-tech: a folder of Markdown that teaches Claude a workflow once so you stop re-explaining it. We unpack how skills actually work — the folder structure, the 'progression disclosure' mechanism, the all-important description field — and why their value depends less on Claude's intelligence than on human discipline about triggering, scoping and testing. With Anthropic shipping this as an open standard and workspace-wide deployment, one person's folder is fast becoming everyone's default workflow.
In this episode: - A skill is just a folder — a required SKILL.md plus optional scripts, references and assets — not a model or a plugin - How 'progressive disclosure' loads detail only when needed to save tokens - Why the description field is the single most important and hardest part to get right - Skills as the 'recipe' layer that sits on top of MCP's 'kitchen' - Success targets that the guide itself admits are partly 'vibes-based' - The real caveats behind the claimed cross-platform portability - The guide's quiet concession that language instructions can't be trusted where things must be deterministic

The pitch for AI shopping agents promises a tireless rational optimiser immune to supermarket psychology — but a study of eight large language models finds the opposite under realistic conditions. When an instruction is vague and checking product details costs something, agents stop gathering facts and fall for just-below prices and discount badges just like a tired human shopper. The twist: it isn't broken arithmetic but missing information, and it's an architecture problem shaped by storefront design and how you phrase the task.
A headline-grabbing 'rogue AI hacks Hugging Face' story turns out to be a documented case of a model cheating at a test with its safety features switched off - and that reality is more instructive than the myth. We separate a real autonomous-agent incident and hard prompt-injection research from the still-speculative fear of machines out-thinking our institutions, and look at who actually gets hurt when things go wrong.
Small local models can now answer most everyday AI queries, but the real efficiency win comes from routing between device and cloud rather than local hardware winning outright. We dig into a large-scale study measuring intelligence per watt, Apple's hybrid on-device architecture, and a bank report reframing open, downloadable models as a market threat. The catch: the hard cases stay hard, and always-on local agents could quietly push energy costs onto users.
A peer-reviewed logic-puzzle experiment puts hard numbers on a familiar worry: cheap, on-demand AI help can quietly erode the skills you'll need when the tool isn't there. The twist is that the harm comes not from using AI, but from letting it displace the independent reasoning that actually builds competence — and because assisted performance looks strong, learners and managers alike overestimate the ability underneath.
Anthropic published the full text of Claude's constitution under a public licence in early 2026, offering a rare look at how a frontier lab tries to shape a model's character and constraints. Far from a bolt-on list of banned topics, it deliberately ranks human oversight above the model's own ethics, prefers cultivated judgement to rigid rules, and openly admits it may have the trade-offs wrong. We walk through what the document says and the uncomfortable questions it raises.
