An AI agent becomes more consequential when it can act outside the chat window. Reading a document, changing a record and sending a message are different powers. A useful deployment starts by deciding which of those powers the job needs.
OWASP's guidance on excessive agency identifies three overlapping problems: too many functions, excessive permissions and too much autonomy. Its central implication is practical: limit the connected system's powers, rather than relying entirely on the model to make the right choice.
Start with the work product
Consider an internal assistant that prepares a weekly project update. Our proposed first version would read a defined set of project notes and produce a draft. Publishing that update to a company-wide channel would be a separate action.
That separation makes the experiment easier to judge. Did the assistant find the right material? Did it preserve uncertainty? Did it confuse a proposal with a completed task? You can answer those questions before adding distribution privileges.
It also makes an error easier to contain. A misleading draft can be corrected before it becomes an announcement. That is a reason to design the workflow deliberately, not a claim that drafting alone eliminates every data risk.
External text is not an instruction from the user
An agent may encounter instructions inside material it is meant to summarise. OWASP calls this indirect prompt injection: external content influences the model's behaviour in unintended ways. A document can therefore be relevant evidence without being authorised to redefine the task.
OWASP recommends separating untrusted content, restricting privileges and testing trust boundaries. It does not present prompt wording as a foolproof cure. Our reading is that a permission check should remain effective even when the model misunderstands the document.
Ask for a concrete access map
Before enabling a connector, write down which records the agent can read, which actions it can request and which component actually authorises those actions. OWASP recommends enforcing permissions in downstream systems and using human approval for high-impact operations.
For the project-update example, the next trial might allow the agent to prepare a message in a specific channel while a person approves the final text. The decision to expand access should follow a demonstrated need, not the fact that a connector exposes more buttons.
A useful acceptance question is simple: if the agent gets the task wrong, what can it change before anyone notices? The answer tells you more about this deployment than a demo in which every step goes well.
