DeepAgents CLI is a versatile tool designed to facilitate coding, research, and agent-building with persistent memory capabilities, allowing users to create and manage custom DeepAgents directly from the terminal. It enables users to read, write, and edit project files, execute shell commands with approval, search the web, and make HTTP requests, among other tasks. The tool supports models from Anthropic and OpenAI, with Claude Sonnet 4 as the default and Tavily for web searches, and requires setting up API keys in a .env file for seamless integration. A standout feature is the persistent memory system, which allows agents to learn and recall information across sessions, storing knowledge in organized memory files that can be manually verified or queried by the agent. Users can create specialized agents for various projects or roles, manage these agents, and reset them to default states as needed. The CLI encourages best practices for memory management, such as using descriptive filenames and organizing by topic, to ensure efficient and reliable use of stored knowledge.
