Agent terms, in plain language

Every term stated honestly. No hype.

• Agent

  Software that can take actions for you — not just answer questions: it plans steps and uses tools (search, files, code) to finish a task.

• Tool call

  The moment an agent uses a tool — a structured request to run a function: fetch a page, query a database, send a message.

• MCP

  Model Context Protocol — an open standard plug that lets any agent talk to any tool server.

• Orchestrator

  The manager that decides which agent does what: a host program that routes work between models and tools and enforces the rules.

• Guardrail

  A hard rule an agent cannot cross — a check outside the model (a validator, allowlist, or gate) that blocks unsafe actions.

• Small language model (SLM)

  A model small enough to run on your own device — a few billion parameters handling routine agent steps cheaply and privately.

• Context window

  How much an agent can keep in mind at once — the amount of text a model can consider in one go.

• RAG

  Retrieval-augmented generation — the agent looks up real documents before answering, so answers cite facts instead of memory.

• Verifier

  A second check on an agent's work — a test, build, or reviewer that decides whether the output is accepted.

• Human in the loop

  A person approves before anything important happens — consequential actions wait for human confirmation.
