Agents Prefer CLIs To Improve Tooling Accuracy
6.8
Relevance ScoreJeremy Daer of 37signals says agents should use command-line interface (CLI) tools instead of REST APIs to reduce context-window demands and improve accuracy when chaining multiple tool calls. He argues CLIs let cheaper, faster models (gpt-5-nano, haiku-4.5) reliably succeed, while raw API use requires costly strong models (gpt-5.2, opus-4.5) and increases token costs for autonomous agents.
