# Glossary

> Current Phinite terms for the agent-first product model.

Primary reference for the **Agent Graph** mental model. Avoid legacy terms listed under [Dead terms](#dead-terms-do-not-use).

## Primary objects

| Term                   | Meaning                                                                                             |
| ---------------------- | --------------------------------------------------------------------------------------------------- |
| **Agent Graph**        | The workflow you design in Graph Studio. Types: Conversational or Autonomous.                       |
| **Conversational**     | Voice/chat graph for real-time user conversations.                                                  |
| **Autonomous**         | Background graph for scheduled tasks, monitoring, and automation without a live user.               |
| **Node**               | Canvas building block (Start, Master Agent, Child Agent, Tool, End, registry agent). Legacy: Block. |
| **Build**              | Immutable snapshot of an agent graph + pinned tool versions, ready to deploy.                       |
| **Agent Build**        | Same as **Build** — the deployable artifact created from the Build dialog.                          |
| **Environment**        | DEV, UAT, or PROD — where a build runs and which env variables apply.                               |
| **Channel**            | Messaging ingress (WhatsApp, Slack, Teams, web chat, voice, email, …) wired to a build.             |
| **Chat API**           | HTTP chat endpoint for Conversational graphs — deploy target separate from channels.                |
| **Trigger**            | Webhook or schedule that starts an Autonomous graph run (API, Cron, background task).               |
| **Session**            | One execution of an agent graph run, recorded in observability logs.                                |
| **Agent Card**         | Public identity + metadata for an agent exposed over A2A (skills, tags, visibility).                |
| **Agent Card version** | One expose registration; status **TEST** or **LIVE**.                                               |
| **Agent Registry**     | Workspace catalog of exposed A2A agents.                                                            |
| **Tool**               | Callable integration or custom function used by nodes in an agent graph.                            |
| **RAG Data**           | Workspace knowledge collections attached to agent nodes for retrieval.                              |
