Your agent's blast radius matters more than your prompt injection defence

An internal-agent developer argues the more important question than prompt injection defense is what an agent can reach if it goes rogue. Their debugging helper ended up with read access to an entire database (needing one table), tokens for internal services that trust it by default, secrets in environment variables, and standing access requiring no escalation. The takeaway: scope agent tool access by least privilege and isolate secrets, or injection just detonates an already-armed bomb. The author asks how others scope agent access and secrets without neutering them.
