# Rename or redescribe an inline sub-agent

`PATCH /api/v1/agents/{agent_id}/sub-agents/{sub_agent_id}`

## Request

- Base URL: `https://cp.xenovia.io` (the document declares no server; this is the origin it was published from)
- URL: `https://cp.xenovia.io/api/v1/agents/{agent_id}/sub-agents/{sub_agent_id}`
- Auth: none declared

``{name?, description?}``. Its guardrails, capabilities and keys refer
to it by id and stay with it. Audited ``agent.sub_agent.update`` with
each changed field before and after. A rename also drops the runtime's
cached verifications of its keys, which name it.

## Path parameters

- `sub_agent_id` string, uuid, required
- `agent_id` string, uuid, required

## Headers

- `Authorization` string, nullable
- `X-Request-ID` string, nullable

## Request body

- SubAgentUpdate: An inline sub-agent's name or description. Renaming changes nothing else: its guardrails, capabilities and keys refer to it by id.
  - `name` string, nullable
  - `description` string, nullable

## Response `200`
