에이전트 업데이트

Parameters
agentID: string
description?:optional string

Description. Omit to preserve; send empty string or null to clear.

mcpServers?:optional list<BetaManagedAgentsURLMCPServerParams>

MCP servers. Full replacement. Omit to preserve; send empty array or null to clear. Names must be unique. Maximum 20. Every server must be referenced by an mcp_toolset in the agent's resulting tools; unreferenced servers are rejected. See the MCP connector guide.

metadata?:optional array<string,string>

Metadata patch. Set a key to a string to upsert it, or to null to delete it. Omit the field to preserve. The stored bag is limited to 16 keys (up to 64 chars each) with values up to 512 chars.

model?:optional Model

Model identifier. Accepts the model string, e.g. claude-opus-5, or a model_config object for additional configuration control. Omit to preserve. Cannot be cleared.

multiagent?:optional BetaManagedAgentsMultiagentParams

A coordinator topology: the session's primary thread orchestrates work by spawning session threads, each running an agent drawn from the agents roster.

name?:optional string

Human-readable name. Must be non-empty. Omit to preserve. Cannot be cleared.

skills?:optional list<BetaManagedAgentsSkillParams>

Skills. Full replacement. Omit to preserve; send empty array or null to clear.

system?:optional string

System prompt. Omit to preserve; send empty string or null to clear.

tools?:optional list<Tool>

Tool configurations available to the agent. Full replacement. Omit to preserve; send empty array or null to clear. Maximum of 128 tools across all toolsets allowed.

version?:optional int

The agent's current version, used to prevent concurrent overwrites. Obtain this value from a create or retrieve response. Must be at least 1 if specified. When supplied, the request fails if it does not match the server's current version; omit to apply the update unconditionally.

betas?:optional list<AnthropicBeta>

Optional header to specify the beta version(s) you want to use.

workspaceID?:optional string
Returns
class BetaManagedAgentsAgent { $type; $id; $archivedAt; /* 12 more */ }
