Can the agent execute shell or terminal commands?

Codex, Claude Code, Gemini CLI, and Cursor document terminal or shell execution in their coding-agent surfaces. The selected evidence also describes configuration-dependent approval, permission, confirmation, or sandbox boundaries. The selected evidence for ChatGPT and Claude does not establish general shell execution, so those answers do not infer it from broader tool or product capabilities.

Six product answers

What the selected evidence establishes

Know whether command execution is established for the covered surface and whether confirmation or permission rules affect it.
