YOU NEED TO REWRITE YOUR CLI FOR AI AGENTS

CLIs need to be redesigned specifically for AI agents, as their requirements for predictability and defense-in-depth differ a lot from human user needs. Agent-first CLIs should prioritize raw JSON payloads for inputs and offer runtime schema introspection for documentation, and practice context window discipline through field masks and pagination. Good input hardening is necessary to defend against agent hallucinations, alongside explicit documentation to guide agent behavior.

WHERE THINGS STAND WITH THE DEPARTMENT OF WAR

Anthropic announced it has been designated a "supply chain risk" to national security by the Department of War (in the US), a decision the company believes is legally unsound and plans to challenge in court. They clarified that this designation has a narrow scope, applying only to the direct use of their AI models in Department of War contracts, not all customers or broader business relationships.
