This page is larger than the 256 KiB this site keeps, so one side of the diff below stops where the stored text does.

406406| `agents` | `Record<string, [`AgentDefinition`](#agentdefinition)>` | `undefined` | Programmatically define subagents |
407407| `agentProgressSummaries` | `boolean` | `false` | When `true`, generate one-line progress summaries for subagents and forward them on [`task_progress`](#sdktaskprogressmessage) events via the `summary` field. Applies to foreground and background subagents |
408408| `allowDangerouslySkipPermissions` | `boolean` | `false` | Enable bypassing permissions. Required when using `permissionMode: 'bypassPermissions'` |
409| `allowedTools` | `string[]` | `[]` | Tools to auto-approve without prompting. This does not restrict Claude to only these tools; unlisted tools fall through to `permissionMode` and `canUseTool`. Use `disallowedTools` to block tools. See [Permissions](/docs/en/agent-sdk/permissions#allow-and-deny-rules) |
409| `allowedTools` | `string[]` | `[]` | Tools to auto-approve without prompting. This does not restrict Claude to only these tools. If you name one of the [task-tracking tools](/docs/en/agent-sdk/todo-tracking#model-availability) here, Claude Code also opts the session in. Other unlisted tools fall through to `permissionMode` and `canUseTool`. Use `disallowedTools` to block tools. See [Permissions](/docs/en/agent-sdk/permissions#allow-and-deny-rules) |
410410| `betas` | [`SdkBeta`](#sdkbeta)`[]` | `[]` | Enable beta features |
411411| `canUseTool` | [`CanUseTool`](#canusetool) | `undefined` | Custom permission function, invoked only when the [permission flow](/docs/en/agent-sdk/permissions#how-permissions-are-evaluated) falls through to a prompt. Not invoked for calls auto-approved by `allowedTools`, allow rules, or `permissionMode`. `AskUserQuestion`, connector tools [your organization set to `ask`](/docs/en/mcp#organization-controls-on-connector-tools), and MCP tools marked [`requiresUserInteraction`](/docs/en/mcp#require-approval-for-a-specific-tool) reach it even if you've allowed them; in `dontAsk` mode these are denied instead. See [`CanUseTool`](#canusetool) for details |
