Overview
Human DX focuses on discoverability and forgiveness, while Agent DX prioritizes predictability and defense-in-depth. Retrofitting a human-first CLI for AI agents is ineffective, necessitating a design specifically tailored for AI agents from the outset.

- Praise: The notion that LLM assistants could drive a shift towards making all app features accessible via textual interfaces highlights the potential for improved user interaction with AI.
- Praise: Adapting GUIs to be wrappers around command line interfaces could streamline AI interactions, making it easier for AI agents to leverage existing tools.
- Concern: The speculative nature of the proposed CLI design raises concerns about its actual effectiveness and practicality in real-world applications.
- Concern: Relying on JSON schemas for AI agents may lead to inefficiencies, as it could consume excessive tokens in context, limiting the model's performance.
- Concern: The assumption that agents work better with JSON over documented flags lacks validation, creating skepticism about its reliability.
