# Agent (/docs/concepts/agent)



An Agent is the core working unit in Buda. It combines identity, instructions, files, tools, and connected channels into one operational AI worker.

What an Agent includes [#what-an-agent-includes]

| Part         | Role                                                        |
| ------------ | ----------------------------------------------------------- |
| Identity     | Name, description, and role of the Agent                    |
| Instructions | System prompt, behavior rules, and operating constraints    |
| Drive        | Private SSD workspace (`/agent`) the Agent can reference    |
| Skills       | Extra capabilities the Agent can call when needed           |
| Channels     | External communication surfaces bound to the Agent          |
| Sessions     | Independent conversation contexts created as users interact |

What each Agent means for billing [#what-each-agent-means-for-billing]

Each Agent you purchase includes three things:

1. **One human member slot** — invite one team member per Agent
2. **One dedicated compute sandbox** — isolated CPU + RAM + SSD (`/agent` directory)
3. **Monthly credits added to the Space pool** — not a per-Agent cap; credits accumulate at the Space level

**Example:** A Pro Space with 5 Agents gets 5 × 20,000 = 100,000 credits/month shared across all Agents.

How an Agent fits into the product [#how-an-agent-fits-into-the-product]

```
Workspace / Space
    -> Agent
        -> Drive
        -> Skills
        -> Channels
        -> Chat Sessions
```

One workspace can have multiple Agents. Each Agent can focus on a different job, such as customer support, finance ops, recruiting, or investment research.

When to create a new Agent [#when-to-create-a-new-agent]

Create a separate Agent when you need:

* A different knowledge base
* A different tone or role
* Different channel routing
* Different permissions or skills
* Cleaner isolation between teams or workflows

Good Agent design [#good-agent-design]

* Keep one Agent focused on one job
* Give it a clear name and mission
* Upload only the files it should actually use
* Add channels after the core behavior is already stable
* Install skills deliberately instead of turning everything on
