# Glossary

The words Falcon uses, in plain language, in alphabetical order.

Each term links to the guide that explains it in full. The API and MCP keep a few older names: a workflow is a `pipeline` there.

**Agent**: A named assistant that talks to your customers or does work for your team. You shape it in plain words: instructions, skills, knowledge, tools, memory, voice and channels. See [Agents](https://falcon.com/docs/agents).

**Built on**: An agent can build on another agent, so a change to the one underneath reaches every agent built on it. Falcon shows which agents a change would affect before you make it. See [Built on this](https://falcon.com/docs/agents#built-on).

**Check**: A test Falcon runs on what people type, such as an identity's details, before it is saved or used. A workflow step can also be a check instead of an agent. See [Checks](https://falcon.com/docs/company-settings#checks).

**Draft**: The version of an agent or workflow that people are still changing. Customers never meet a draft; you can test it at any time. See [Make a version Live](https://falcon.com/docs/agents#publishing).

**Engagement**: What your company counts as someone engaging, such as replying or booking a meeting. Each engagement can start a side chain. See [Engagements](https://falcon.com/docs/workflows#engagements).

**Identity**: A person or a place an agent acts for, such as Dana in sales or the Downtown store. Identities are records your company keeps; they never sign in and are not users. See [Identities](https://falcon.com/docs/identities).

**Live**: The version of an agent or workflow that customers meet and that runs for real. Only someone with permission makes a version Live, and you can go back to an earlier one. See [Publish and roll back](https://falcon.com/docs/workflows#workflow-publish).

**Side chain**: Extra steps that hang off one step of a workflow and run only when something happens: someone is interested, replies STOP, or the step fails. See [Side chains and retries](https://falcon.com/docs/workflows#side-chains).

**Start**: What makes a workflow run: a schedule, an event from a connected app, a conversation arriving, another system calling it, or another workflow failing. A workflow can have more than one start. See [How a workflow starts](https://falcon.com/docs/workflows#workflow-starts).

**Waiting for you**: One place for the drafts that need a person before they are sent, from every workflow. You send a draft as it is, edit it first, or decide not to send it. See [Waiting for you](https://falcon.com/docs/workflows#waiting-for-you).

**Workflow**: A series of steps that runs when something happens, such as a new email, a form, a call or a time of day. Each step is an agent or a check. Like agents, workflows have drafts and a Live version. See [Workflows](https://falcon.com/docs/workflows).
