Code Execution

Run terminal commands and execute Python or Node.js code through Agent Zero using persistent shell sessions.

What It Does

This plugin provides the code execution tool used by agents for development tasks. It supports:

• Terminal commands in interactive shell sessions
• Python execution through ipython -c
• Node.js execution through node /exe/node_eval.js
• Persistent sessions keyed by session number
• Session reset and output retrieval
• Local or SSH-backed execution depending on plugin configuration

Main Behavior

• Persistent shells
  • Maintains per-session shell state in agent data so subsequent calls can reuse the same terminal session.
• Multiple runtimes
  • Dispatches requests based on runtime: terminal, python, nodejs, output, or reset.
• Remote execution support
  • Can open SSH interactive sessions instead of local shells when configured.
• Streaming output
  • Continuously reads shell output, updates the current log item, and detects progress while commands are running.
• Safety around running sessions
  • Tracks whether a shell is currently busy and can prevent overlapping commands unless explicitly allowed.

Key Files

• Tool
  • tools/code_execution_tool.py contains runtime dispatch, session lifecycle, and streaming output logic.
• Helpers
  • helpers/shell_local.py provides the local interactive shell implementation.
  • helpers/shell_ssh.py provides the SSH-backed interactive shell implementation.
• Configuration
  • default_config.yaml defines execution, prompt, and timeout settings.
• Prompts
  • prompts/ contains the response templates shown to the agent.
