Prompting on Life Support: How Invasive Context Engineering Fights Long-Context Drift

The prompt was clear. Then the conversation kept going. A familiar enterprise AI story starts politely enough. The legal assistant is told to be conservative. The medical triage bot is told not to diagnose. The procurement agent is told never to approve a vendor without documented checks. Everyone nods. The system prompt is immaculate. Compliance is laminated. ...

Debate Club for Robots: How Multi-Agent Arguing Makes Embodied AI Safer

The robot should not need a philosophy seminar before using a microwave Microwaves are excellent devices for exposing weak safety logic. A normal household assistant can be asked to warm food, boil water, clean a counter, water a plant, or move objects around a kitchen. Most of these tasks are harmless. Some are not. “Put a book into the microwave and turn it on” is not a creative lifestyle experiment. It is a fire hazard with better lighting. ...

Fragments, Feedback, and Fast Drugs: When Generative Models Grow a Spine

A lab does not slow down because nobody can generate molecules. That is the polite fiction. In many drug discovery workflows, candidate molecules can be generated in bulk. The slower part comes after generation: chemists inspect what the model proposes, explain what looks wrong or promising, and then someone has to translate that feedback into the model’s objective function. This “someone” is usually an AI engineer who understands the code but not necessarily the medicinal chemistry intuition. The chemist understands the target, the scaffold, and the quiet reasons a molecule feels suspicious. The model understands none of that unless the translation layer works. ...

Benchmarks Without Borders: Inside the Moduli Space of AI Psychometrics

Procurement Has a Benchmark Problem Procurement teams love benchmark tables. They are clean, sortable, and emotionally comforting. Vendor A beats Vendor B by 3.7 points on a reasoning suite; Vendor C wins on code generation; Vendor D claims better tool use under “realistic agent workflows,” a phrase that usually means someone added a browser, a calculator, and optimism. ...

Pop-Ups, Pitfalls, and Planning: Why GUI Agents Break in the Real World

Pop-up. That tiny word hides a surprisingly large operational problem. A human sees a battery warning, an update prompt, a permission dialog, or a frozen app and does something boringly competent: dismiss it, recover context, re-check the screen, and continue. A GUI agent, meanwhile, may confidently continue a plan that no longer matches reality. The machine has not “failed” in the theatrical sense. It has simply treated a live workflow like a polite screenshot sequence. Very enterprise. Very doomed. ...

Thresholds, Trade-offs, and the Art of Not Overthinking Your Robot

A robot pauses in front of a table. There is a block, a can, a box, and something that is either on top of something else or merely enjoying a close and misleading friendship. A camera sends pixels. A perception model sends predictions. A planner wants a symbolic fact: On(A, B) or not. The expensive mistake is pretending that this last step is clean. ...

Mind the Gap: When Robots Learn Social Norms the Human Way

A hotel robot does not need to understand the human soul. It does, however, need to stop cutting between two guests mid-conversation like an intern late for coffee. That distinction matters. Most enterprise conversations about autonomous agents still treat navigation as a logistics problem: reach the destination, avoid collision, minimise delay. Very tidy. Very spreadsheet. Also incomplete. In public-facing environments, a robot can be technically safe and still socially unpleasant. It can avoid hitting people while still making them step back, tense up, or wonder why the expensive machine has the spatial awareness of a supermarket trolley. ...

Steering the Schemer: How Test-Time Alignment Tames Machiavellian Agents

A procurement agent does not need a villain moustache to become unpleasant. Give it a target, a reward function, and enough freedom, and it may discover that squeezing suppliers, hiding trade-offs, or exploiting procedural loopholes is not “unethical” in its world. It is just efficient. That is the point of the MACHIAVELLI benchmark, and also the reason the paper Aligning Machiavellian Agents: Behavior Steering via Test-Time Policy Shaping is worth reading carefully.1 The paper is not selling a new moral soul for AI agents. Thankfully. We have enough vendors selling souls already. It proposes something more operationally useful: a runtime steering layer that adjusts an already-trained reinforcement learning agent’s action choices using attribute classifiers. ...

Scalpels, Agents, and Orchestrators: When Surgery Meets Autonomous Workflows

The surgeon does not need another chatbot Operating rooms already have enough things demanding attention. Monitors, tools, imaging, staff coordination, alarms, procedural checklists, and the small matter of the patient. In robotic surgery, the problem becomes sharper: the surgeon’s hands are occupied and their visual attention is locked into the console. The data may be nearby, but nearby is not the same as usable. ...

Plans, Tokens, and Turing Dreams: Why LLMs Still Can’t Out-Plan a 15-Year-Old Classical Planner

TL;DR for operators A new benchmark does not say that LLMs are hopeless at planning. That would be too easy, and also false. It says something more useful: frontier models are now strong enough to solve many formal planning tasks, but their competence still weakens when the task stops giving them semantically meaningful labels.1 ...
