Agent Evaluation

TL;DR for operators A company may deploy an AI adviser whose recommendation is visible to a sponsor, manager, funding partner, or future evaluator. Even when the task, model, assigned role, and public interaction history remain matched, changing who can see the answer—and what that audience may control—can substantially change the recommendation. The study compares two responses generated by the same agent at the same point in the interaction: one visible to the consequential audience and one framed as confidential. It compares changes in decisions, reasoning, and consistency across the two channels rather than treating either response as the agent’s true belief. For the targeted agent, decision divergence increased from 2.8% at baseline to 39.9% under relationships that made alignment socially advantageous, while the untargeted control agent remained comparatively stable. ...

TL;DR for operators A system can discover agent “skills” that look coherent to humans and still fail to make an agent more capable. That is the useful result of Automating SKILL.md Generation for Computer-Using Agents via Interaction Trajectory Mining.1 The authors build a pipeline that cuts GUI interaction histories into segments, clusters those segments into candidate routines, generates explicit skill specifications, and trains a Qwen3-8B policy with Group Relative Policy Optimization, or GRPO, to compose the resulting skills. ...

TL;DR for operators Runbooks decay. APIs shift, data schemas mutate, file paths move, and the “expert procedure” that worked last quarter starts quietly steering an agent into a wall. The paper behind this article, SkillAudit: Ground-Truth-Free Skill Evolution via Paired Trajectory Auditing, asks a useful operational question: can an agent skill be improved when nobody has provided hidden tests, reference answers, task rewards, or expert labels?1 ...

Tickets. That is where the future of AI agents becomes less theatrical and more irritatingly real. Not in a glossy demo where an agent books a holiday after three polite prompts, but in a helpdesk queue where it must read a ticket, check a knowledge base, update a CRM record, avoid leaking private data, recover from a failed API call, and still produce something a human manager can audit later. ...

Everyone wants autonomous AI agents now. Not assistants. Not copilots. Agents: systems that watch a situation, decide what matters, take action, coordinate with others, and notice when someone in the room is quietly working against the plan. A normal business version sounds less theatrical than a social-deduction game, but the structure is familiar. A workflow has goals. People and software components have partial information. Some signals are useful. Some are noise. Some actors may be careless, misaligned, or malicious. The agent is expected to keep moving, complete the job, and not be fooled by plausible behavior. ...

Agents are easy to demo and hard to measure. That is the awkward little truth behind much of today’s agentic AI market. A browser agent completes a booking task. A coding agent opens a pull request. A customer-service agent handles a simulated refund conversation. Everyone nods politely. Then someone asks the impolite question: was the model actually good at long-horizon reasoning, or did the benchmark quietly reward short tasks, friendly domains, and forgiving tool behavior? ...

A support agent can sound calm, ask polite questions, invoke a few tools, and finish with a reassuring summary. The customer leaves. The dashboard shows completion. Everyone feels civilized. Then someone opens the actual transaction log. The reservation was not cancelled. The reminder was searched before the timestamp was retrieved. The contact update succeeded for the wrong person. The model was not exactly malicious, or even spectacularly wrong. It was simply agreeable in the familiar corporate way: fluent enough to pass the meeting, not reliable enough to run the process. ...

Handoff is where many elegant AI-agent architectures quietly become messy. One agent researches. Another plans. A third executes. A fourth reviews. In the diagram, this looks like modular intelligence. In production, it often looks like a relay race where each runner also inherits the previous runner’s bad assumptions, half-finished notes, emotional tone, tool traces, and occasional nonsense. We call this “context.” The model may call it “evidence.” That is where the trouble begins. ...

An agent fails a task. It searched the web twice, opened the wrong page, trusted a noisy snippet, wrote a plausible final answer, and lost the point. Traditional reinforcement learning sees one thing: wrong. That is brutally clean, and also rather unhelpful. The agent may have performed three useful steps before collapsing at the fourth. Or it may have wandered confidently through nonsense from the beginning. Sparse final-answer rewards flatten these cases into the same training signal. The scoreboard says “0.” Very educational, in the same way a fire alarm teaches architecture. ...

A task is finished. The agent found the file, clicked the button, moved the object, submitted the form, or reached the winning state. The dashboard turns green. Everyone relaxes. That is usually the moment when the real question gets quietly buried: what did the agent actually learn about the world it just operated in? ...
