Definition
Excessive agency is a privilege problem wearing AI clothing. The system holds authority beyond what its task needs: broader data access, write permissions, or the ability to take consequential action without confirmation.
Why it compounds every other AI weakness
Prompt injection, jailbreaks and simple model error all become more serious in proportion to what the system may do. Reduce the authority and every one of those failures becomes less costly, without having to solve any of them.
Where the excess accumulates
- Credentials scoped to the application rather than the user
- Write or delete access where read would suffice
- Tools retained after the feature that needed them shipped
- Irreversible operations available without confirmation
- Access to data the task never requires
- Untrusted Input
- AI Agent
- Excessive Permission
