## Update Agent Config

**patch** `/v5/agent_configs/{agent_config_id}`

Partially update a stored agent config; only fields present in the request body are changed.

`persistent_workspace` and `repos` are both patchable — an explicit null on
`repos` clears the override back to the deployment default, while the
always-present fields (name, system_prompt, harness, allowed_tools, model, and
persistent_workspace) reject an explicit null. Because `persistent_workspace`
and `repos` are read when a task is created and are fixed for a task's life,
changing them affects only tasks created afterward, not one already running. The
optional `task_id` query parameter opts into a live-config side effect: after
the row is persisted, the changed pass-through fields (system_prompt, model,
harness, and allowed_tools split into harness tools versus MCP servers) are
shallow-merged into that running task's params on Agentex in a background task so
the worker picks them up on its next turn; `persistent_workspace` and `repos`
are intentionally not forwarded to a running task. That side effect runs after
the response is sent, is best-effort, and no-ops if the task does not exist or the
caller does not own it. A user caller can only update a config they created unless
fine-grained access control grants access.

### Path Parameters

- `agent_config_id: string`

### Query Parameters

- `task_id: optional string`

  If set, after persisting the patch we shallow-merge the changed fields into this task's params column on Agentex so the worker picks up the new values on its next turn. Caller-provided context — Agentex enforces task ownership via its own auth, so the side-effect no-ops if the caller doesn't own the task.
