Every LLM provider keys its prompt cache on the prefix of the request. Mutate the system prompt, tool schema, or message history mid-conversation and you invalidate the cache for the rest of the session — a single slip can 10x the cost. The four forbidden mutations, the permitted ones, and how to enforce them statically.

An autonomous agent holds an API key, a shell, and the ability to send messages as you — running while you sleep. The security question is not whether it can be jailbroken; it is what the blast radius is when it misbehaves. The controls that make unattended safe.

Part 1 treated AI as a Junior+ teammate you prompt. This is the leap to an agent that runs every 15 minutes with no one watching: the anatomy of an autonomous loop, the model-routing economics that keep it cheap, and the kill switches that keep an unattended agent from doing damage.
