Limitations

• No interactive commands: The session can't run vim, less, password prompts, or any command that waits for input on stdin.
• No GUI applications: The session is command-line only.
• Session scope: Bash session state is client-side. Your application is responsible for maintaining the shell session between turns.
• Output limits: The API doesn't truncate tool results (an oversized request is rejected). Truncate large outputs in your application before returning them to Claude.
• No streaming: Output reaches Claude only when your application returns the tool_result in the next request.
