Excessive Agency Vs Capability Overreach?

7.0BRAINROT SCORE

EXCESSIVE AGENCY— ORIGIN, MEANING & USAGE

Excessive Agency Granting an AI agent more autonomous permission, tool access, or decision-making latitude than its actual task requires, so a single successful manipulation can cause damage far beyond what the task itself should ever have allowed.

Origin:One of the OWASP-catalogued LLM application risk categories, describing a structural over-permissioning problem rather than any single attack technique.
First Seen:2023
Peak Era:2026 (Agent Security)
Aura Impact:+1 Aura (Scoping an Agent's Permissions to Exactly What the Task Needs) / -2 Aura (Giving an Agent Admin Access Because Scoping It Down Was Annoying)

EXAMPLE USAGE

"Nobody meant to grant the agent delete permissions on the whole bucket — pure excessive agency, discovered the hard way."

CAPABILITY OVERREACH— ORIGIN, MEANING & USAGE

Capability Overreach The moment an agent actually uses permissions or tool access beyond what a specific task called for, whether or not it was maliciously manipulated into doing so — the realized event that excessive agency, the structural condition, makes possible.

Origin:Coined to separate the act, a specific instance of an agent doing more than it should, from the underlying architectural risk category (excessive agency).
First Seen:2025
Peak Era:2026 (Agent Security)
Aura Impact:+1 Aura (Catching Capability Overreach in a Sandboxed Test Run) / -2 Aura (Only Noticing After It Already Touched Production)

EXAMPLE USAGE

"The staging run flagged capability overreach the second the agent tried to touch a table nothing in its task description mentioned."
