# Practical ways to use the Claude Agent SDK ✅ Request user approval before dangerous operations with 6 flexible response patterns. Approval and User Input uses the `canUseTool` callback to intercept dangerous operations and `AskUserQuestion` for requirements gathering. 📌 Title: Handling Approvals and User Input 🔗 URL: 🧩 Overview `canUseTool` intercepts each tool call with 6 response patterns: approve, approve with modifications, approve and remember, deny, suggest alternative, or full redirect. `AskUserQuestion` lets Claude present multiple-choice questions to users. 🛠 How to use it Define a `canUseTool` callback that returns `PermissionResultAllow` or `PermissionResultDeny` based on tool name and arguments. 🏗 Practical usage - Build an interactive approval UI that detects file deletions or Bash execution and prompts y/n. You can approve with modifications like "scope all Bash commands to /tmp/sandbox". - Use "approve and remember" with `updated_permissions` to persist rules in `.claude/settings.local.json`. - Combine `AskUserQuestion` with `plan` mode to gather requirements before making changes: "Which tech stack for the mobile app?" with multiple choice options. 💡 Use cases 🛡 Interactive approval UI for dangerous operations 📋 Multi-choice requirements gathering 🔐 Persistent approval rule learning ⚠️ Watch out AskUserQuestion is not available in sub-agents. Questions are limited to 1-4, choices to 2-4. In Python, `can_use_tool` requires streaming mode plus a dummy PreToolUse hook. #ClaudeAgentSDK# #AI#
