2. **Claude asks a question**: Claude calls the `AskUserQuestion` tool. Check if `tool_name == "AskUserQuestion"` to handle it differently. If you specify a `tools` array, include `AskUserQuestion` for this to work. See [Handle clarifying questions](#handle-clarifying-questions) for details. <Warning> - **The callback never fires for auto-approved tools.** Any approval earlier in the [permission evaluation flow](/docs/en/agent-sdk/permissions#how-permissions-are-evaluated), an allow rule or a mode like `acceptEdits` or `bypassPermissions`, resolves the call before `canUseTool` is consulted. If you list a tool bare in `allowed_tools`, a `canUseTool` check for that tool never runs unless an ask rule or `plan` mode routes the call back to a prompt. For logic that must apply to every tool call, use a [`PreToolUse` hook](/docs/en/agent-sdk/hooks), which executes before the rest of the flow and can allow, deny, or modify requests. + **The callback never fires for auto-approved tools.** Any approval earlier in the [permission evaluation flow](/docs/en/agent-sdk/permissions#how-permissions-are-evaluated), an allow rule or a mode like `acceptEdits` or `bypassPermissions`, resolves the call before `canUseTool` is consulted. If you list a tool bare in `allowed_tools`, a `canUseTool` check for that tool runs only when the [evaluation flow](/docs/en/agent-sdk/permissions#how-permissions-are-evaluated) routes the call back to a prompt, such as an ask rule or `plan` mode. For logic that must apply to every tool call, use a [`PreToolUse` hook](/docs/en/agent-sdk/hooks), which executes before the rest of the flow and can allow, deny, or modify requests. - `AskUserQuestion`, MCP tools marked [`requiresUserInteraction`](/docs/en/mcp#require-approval-for-a-specific-tool), and connector tools [your organization set to `ask`](/docs/en/mcp#organization-controls-on-connector-tools) reach the callback even when an allow rule matches. In `dontAsk` mode these calls are denied instead, without invoking the callback. + An allow rule doesn't pre-approve the [actions no mode auto-approves](/docs/en/permission-modes#actions-no-mode-auto-approves); see [How permissions are evaluated](/docs/en/agent-sdk/permissions#how-permissions-are-evaluated) for which of them reach the callback and what happens in `dontAsk` and `auto` mode. </Warning> You can also use the [`PermissionRequest` hook](/docs/en/agent-sdk/hooks#available-hooks) to send external notifications (Slack, email, push) when Claude is waiting for approval.
