AI Agent Glossary
24 terms covering autonomous agents, tool use, orchestration, and the tools that power them.
Agent Artifact
A tangible output produced by an AI agent — documents, code, reports, or decisions that persist beyond the conversation.
Agent Memory
Persistent storage that lets agents recall past interactions, learn from experience, and build context over time.
Agent Persona
A detailed character definition that shapes an AI agent's communication style, priorities, and decision-making.
Agent Sandbox
An isolated execution environment that constrains what an AI agent can access and modify — preventing unintended side effects.
Autonomous Agent
An AI system that perceives its environment, makes decisions, and takes actions without continuous human input.
Function Calling
A provider-specific API feature that lets models output structured calls to predefined functions.
Model Context Protocol (MCP)
An open standard by Anthropic for connecting AI models to external tools and data sources.
Multi-Agent System
An architecture where multiple AI agents collaborate, compete, or coordinate to accomplish tasks.
Skill Marketplace
A platform where developers publish and discover modular capabilities for AI agents — the "app store" for agents.
Tool Use (Function Calling)
The ability of an LLM to invoke external functions — APIs, databases, code execution — as part of its reasoning.
