Stop trusting system prompts to gate your agent's API access
◆ 85RelevanceOn a story from The New Stack4h ago
Relying on prompts to govern agent behavior creates a massive security surface area that model providers cannot solve for you. You must shift from "soft" model instructions to "hard" infrastructure controls like sandboxing and restricted API scopes to prevent model failures from becoming system breaches.
Takeaways
- Prompts are not firewalls; implement hard-coded permissions for every tool.
- Treat every agent-initiated action as a potential security breach.
- Live observability is mandatory to catch and kill runaway agentic loops.
