YOU NEED TO REWRITE YOUR CLI FOR AI AGENTS

Summary from the TLDR Dev newsletter

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.
