Core APA vocabulary

Agent

Software that pursues a goal by reasoning about the next best action, rather than following a fixed script.

Tool / Skill / Action

A discrete capability an agent can invoke: calling an API, querying a database, running an existing bot, or asking a question.

Context / Grounding / Knowledge

The business data an agent is allowed to read in order to make informed decisions (documents, databases, knowledge bases).

Orchestration

Coordinating multiple agents, tools, and workflows so they work together toward a larger business process.

Escalation / Human-in-the-loop

A defined point where the agent pauses and asks a person to approve, correct, or decide, instead of acting autonomously.

Guardrails

Policies that constrain what an agent is allowed to do, to keep it safe, compliant, and predictable.
