Using skills with Deep Agents

Generalist AI agents can perform complex actions by using a small set of tools that give them access to a computer's filesystem and shell. Anthropic introduced the concept of "agent skills," which are folders containing instructions that an agent can dynamically discover and load to perform specific tasks. This approach is more token-efficient and reduces the agent's cognitive load compared to using many distinct, pre-defined tools. LangChain has now added support for these skills to its open-source deepagents-CLI, enabling agents to use a growing library of public skills for tasks like web research.
