What is a Category Rule?
A category rule applies spend policy by type — compute, data, SaaS, ads, payments — so an agent can buy API credits but never wire money.
How it works
Each transaction carries a category.
Rules set per-category ceilings, blocks, or flags.
It's one of the six rule types a spend firewall enforces.
Why it matters
Agents drift: a research agent starts buying compute.
Category rules make the budget explicit per spend type.
FAQ
What categories can I define?
Whatever maps to your ledger: compute, data, SaaS, ads, payments, inference.
What happens when a category is capped?
Transactions in that category over the cap are BLOCKED or FLAGGED — the agent stays in its lane.
