An Agent is a versioned agent definition: model, instructions, tools, MCP servers, skills, memory stores, tool policy and budget. Each create or update that changes `spec` mints a new immutable AgentVersion; a session pins the version it started on, so a change never alters a running conversation.

**Service** Sylphx Agents · **Resource type** `agents.sylphx.com/Agent` · **Name pattern** `orgs/{org}/projects/{project}/envs/{env}/agents/{agent}` · **Shape** `spec_status`

**Not available yet.** Sylphx Agents is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

## Fields

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/agents/{agent}`. |
| `uid` | `string` | `agt_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `AgentSpec` | Desired state: the definition the next version takes. Required. |
| `status` | `AgentStatus` | Observed state. Output only. |

## Methods

Every method of the collection, in the registry's order, with the scope it
needs. The full request, response and examples are one link away.

| Method | Call | What it does |
| --- | --- | --- |
| `GET` | [`get`](/docs/api/agents#get) | Gets an agent. |
| `GET` | [`list`](/docs/api/agents#list) | Lists agents. |
| `POST` | [`create`](/docs/api/agents#create) | Creates an agent and its version 1. |
| `PATCH` | [`update`](/docs/api/agents#update) | Updates an agent. A change to `spec` mints the next AgentVersion; sessions already started keep the version they pinned. |
| `DELETE` | [`delete`](/docs/api/agents#delete) | Deletes an agent and its versions. An agent with sessions is refused with `INVALID_STATE` unless `force` is set, which deletes them too. |
