<Note>
  Setup steps and authentication are in the [Overview](/cli-sdk/overview). This page focuses on the agent resource itself.
</Note>

An **agent** is the AI voice assistant under test. It links to a provider (Vapi, Retell, ElevenLabs, LiveKit, Pipecat, or a custom integration), a system prompt, mock tools, a knowledge base, and a set of personalities. Most evaluation workflows start by creating or selecting an agent.

## Create

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    cekura agents create \
      --project-id 742 \
      --name "Support Bot" \
      --description "Inbound customer support agent" \
      --provider vapi \
      --vapi-assistant-id asst_abc123
    ```

    For complex configs, write a JSON file and pass it:

    ```bash theme={null}
    cekura agents create --from-file agent.json
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    from cekura import Cekura

    client = Cekura()

    agent = client.agents.create(
        project=742,
        agent_name="Support Bot",
        description="Inbound customer support agent",
        provider="vapi",
        vapi_assistant_id="asst_abc123",
    )
    ```
  </Tab>
</Tabs>

## List, get, update

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    # List agents in a project
    cekura agents list --project-id 742

    # Inspect one
    cekura agents get 123

    # Patch fields inline
    cekura agents update 123 --json '{"description": "v2 prompt rolled out"}'

    # Or from a file
    cekura agents update 123 --from-file patch.json
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    # List
    agents = client.agents.list(project_id=742)

    # Fetch one
    detail = client.agents.get(agent_id=123)

    # Partial update
    client.agents.update(
        agent_id=123,
        description="v2 prompt rolled out",
    )
    ```

    `replace()` performs a full PUT instead of a PATCH — use it when you want to overwrite the entire agent definition.
  </Tab>
</Tabs>

## Mock tools

Mock tools let evaluations run without hitting your real backend.

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    # List existing tools
    cekura agents tools-list 123

    # Add a tool
    cekura agents tool-create 123 --from-file booking_tool.json

    # Update / remove
    cekura agents tool-update 123 book_appointment --from-file new.json
    cekura agents tool-destroy 123 book_appointment
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    # List
    tools = client.agents.tools_list(123)

    # Create
    client.agents.tools_create(
        agent_id=123,
        name="book_appointment",
        description="Books an appointment for the caller",
        parameters={"date": "string", "time": "string"},
        mock_response={"confirmation_id": "ABC123"},
    )

    # Update by tool name
    client.agents.tool_update(
        123, tool_name="book_appointment", mock_response={...},
    )

    # Remove
    client.agents.tool_destroy(123, tool_name="book_appointment")
    ```
  </Tab>
</Tabs>

## Knowledge base

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    cekura agents upload-knowledge-base 123 --file ./policies.pdf
    cekura agents get-knowledge-base 123
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    with open("policies.pdf", "rb") as f:
        client.agents.upload_knowledge_base(123, file=f)

    kb = client.agents.get_knowledge_base(123)
    ```
  </Tab>
</Tabs>

## Personalities

Personalities apply across an agent's evaluation runs (e.g. "interruptive", "soft-spoken").

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    cekura personalities enable-for-project 742 --personalities 3,29
    cekura personalities disable-for-project 742 --personalities 3
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    client.agents.enable_personalities(123, personalities=[3, 29])
    client.agents.disable_personalities(123, personalities=[3])
    ```
  </Tab>
</Tabs>

## Duplicate

Quickly fork an agent for A/B testing or a new prompt variant:

<Tabs>
  <Tab title="CLI">
    ```bash theme={null}
    cekura agents duplicate 123
    ```
  </Tab>

  <Tab title="SDK">
    ```python theme={null}
    client.agents.duplicate(agent_id=123)
    ```
  </Tab>
</Tabs>

## Dynamic variables

Dynamic variables let you inject runtime values into an agent's description using `{{ variable_name }}` syntax. You define the variables on the agent and supply their values when sending call data to the observability endpoint.

### List

```bash theme={null}
GET /test_framework/v1/aiagents/{agent_id}/dynamic-variables/
```

Returns all variable definitions for the agent, ordered by name.

**Response**

```json theme={null}
[
  { "id": 1, "name": "prompt", "description": "Full system prompt for this call", "created_at": "...", "updated_at": "..." },
  { "id": 2, "name": "agent_type", "description": "Role of the agent (sales, support, ...)", "created_at": "...", "updated_at": "..." }
]
```

### Create / update

```bash theme={null}
POST /test_framework/v1/aiagents/{agent_id}/dynamic-variables/
```

Accepts a **list** of `{ name, description }` objects. Each entry is upserted by name — existing variables are updated, new ones are created. Returns the full list of definitions after the operation.

```json theme={null}
[
  { "name": "prompt", "description": "Full system prompt override" },
  { "name": "agent_type", "description": "Agent role for this session" }
]
```

### Update one

```bash theme={null}
PATCH /test_framework/v1/aiagents/{agent_id}/dynamic-variable/{id}/
```

Updates a single variable definition (partial update).

```json theme={null}
{ "description": "Updated description" }
```

### Delete

```bash theme={null}
DELETE /test_framework/v1/aiagents/{agent_id}/dynamic-variable/{id}/
```

Returns `204 No Content`.

***

See [Dynamic Agent Description](/documentation/guides/observability/dynamic-prompting) for how to use these variables at call time.
