Overview

Implement Docker sandbox container initialization with a predefined set of custom commands, accessible via /help.

Requirements

Features

1. Custom Container Initialization State

   • Container no longer starts in a blank state
   • Support predefined initialization commands (e.g., environment checks, dependency installation)
   • Initialization commands should be configurable

2. Custom Command Registry

   • Support registering multiple custom commands
   • Each command has a name, description, and execution content
   • Commands grouped by category

3. /help Command

   • Input /help to display all available commands
   • Show name and description for each command
   • Provide user-friendly formatted output

User Scenario

User: /help
Assistant: Available commands:
  /init    - Initialize environment
  /status  - Show current status
  /install - Install dependencies
  /help    - Show this help message

Technical Approach

• Add command configuration in OpenManusProperties
• Create command registry/mechanism
• Intercept /help command in ShellTool or AgentCoordinator
• Provide command execution framework

Open Questions

• Command configuration method (YAML/JSON/code)
• Command execution permission control
