Mid-level interview question
What kinds of tools can an agent have, and which need the most care?
Model answer
Knowledge augmentation (retrievers, SQL, web search), capability extension (calculators, code interpreters), and write actions (send email, update a database, move money).
Reads change what the agent knows; writes change the world, so writes need the most trust and guarding.
