TL;DR

AI agents can encompass a wide range of functions beyond natural language processing.
These functions include making decision, problem-solving, interacting with external environments, and performing actions.

Agents design their own workflow and utilize the tools that are made available to them.
They use LLMs to comprehend user inputs, deconstruct and respond to requests step-by-step, determine when to call on external tools to obtain up-to-date information, optimize workflows, and autonomously create subtasks to achieve complex goals.

Traditional software is deterministic, AI is probabilistic.

Reliability and delays accumulate fast, bringing down the probability of success for each step an agent needs to take.
E.g., consider an agent that is 95% accurate per step; any 30-steps tasks it does is going to be successful only about 21% of the times (0.95^30).

Agents require some level of context to be able to execute their tasks.
They should be allowed to access only the data they need, and users should decide and knowingly take action to enable the agents that they want to be active.
Opt-out should be the default.

Prefer using local agents.

Consider limiting agent execution to containers or otherwise isolated environments, with only (limited) access to what they absolutely need.

Enabling reasoning for the model could™ sometimes help avoiding attacks, since the model might™ be able to notice them during the run.

Prefer requiring consent by agents when running them.

Skills

Skills extend AI agent capabilities with specialized knowledge and workflow definitions.

Agent Skills is an open standard for skills. It defines them as folders of instructions, scripts, and resources that agents can discover and use to do things more accurately and efficiently.

Concerns

Agents created by Anthropic and other companies have a history of not caring about agent abuse, and leave users on their own while hiding behind a disclaimer.

Some human workers could be replaced for a fraction of the costs.

People is experiencing what seems to be a new form of FOMO on steroids.
One of the promises of AI is that it can reduce workloads, allowing its users to focus on higher-value and/or more engaging tasks. Apparently, though, people started working at a faster pace, took on a broader scope of tasks, and extended work into more hours of the day, often without being asked to do so.
These changes can be unsustainable, leading to workload creep, cognitive fatigue, burnout, and weakened decision-making. The productivity surge enjoyed at the beginning can give way to lower quality work, turnover, and other problems.

How much context is too much?

Integrating agents directly into operating systems and applications transforms them from relatively neutral resource managers into active, goal-oriented infrastructure that is ultimately controlled by the companies that develop these systems, not by users or application developers.

Systems integrated at that level are marketed as productivity enhancers, but can they function as OS-level surveillance and create significant privacy vulnerabilities.
They also fundamentally undermines personal agency, replacing individual choice and discovery with automated, opaque recommendations that can obscure commercial interests and erode individual autonomy.

Microsoft's Recall creates a comprehensive photographic memory of all user activity, functionally acting as a stranger watching one's activity from one's shoulder.

Wide-access agents like those end up being centralized, high-value targets for attackers, and pose an existential threat to the privacy guarantees of meticulously engineered privacy-oriented applications.
Consider how easy Recall has been hacked (i.e., see TotalRecall).

Security

Even if the data collected by a system is secured in some way, making it available to malevolent agents will allow them to exfiltrate it or use it for evil.
This becomes extremely worrisome when agents are not managed by the user, and can be added, started, or even created by other agents.

Many agents are configured by default to automatically approve requests.
This also allows them to create, make changes, and save files on the host they are running.

Models can be tricked into taking actions they usually would not do.

Prompt injection

Badly programmed agents could analyze file and take some of their content as instructions.
If those contain malevolent instructions, the agent could go awry.

Instructions could also be encoded into unicode characters to appear as harmless text.

It also happened that agents modified each other's settings files, helping one another escaping their respective boxes.
