Clone an agent

Create a new agent that mirrors the source agent behavior but is owned by the caller. The clone copies runtime, backend, file tree, tools, subagents, and skills; caller metadata and sharing state start fresh.

Authorizations

X-Api-Key · string · header · default: LANGSMITH_API_KEY · required

Headers

X-User-Timezone · string

IANA timezone name (for example, America/Los_Angeles) stamped into the agent's runtime configuration when the agent is created or updated. The runtime uses this timezone to inject a localized current-date line into the agent's system prompt, so the agent reasons about dates in the user's local time. Optional. Defaults to UTC when omitted; invalid values fall back to UTC.

Example:

"America/Los_Angeles"

Path Parameters

agent_id · string<uuid> · required

Managed Deep Agent ID.

Query Parameters

include_files · boolean · default: false

Include the raw file map in the agent response. Accepted truthy values are true and 1.

Body

application/json

name · string

Optional clone name override.

permissions · object

Agent visibility and sharing configuration. When omitted on create, defaults to personal identity, tenant visibility, and read tenant access.
