Agent Guide: ask-user-mcp-app

This document helps AI agents understand and navigate the codebase efficiently.

Quick Overview

This is an MCP App that provides an ask_user tool for AI agents to ask users multiple questions with tab-based navigation and keyboard support. The UI renders inline in the host client (Claude, ChatGPT, etc.).

Key features:

• Multi-question tabs: Ask multiple questions displayed as navigable tabs
• Keyboard navigation: Tab/Shift+Tab for tabs, Arrow keys for options, Enter to select/submit
• "Other" input handling: When user clicks "Other", textbox auto-focuses; Arrow keys work for editing; Tab/Escape blur the input
• Auto-navigation: Single-select questions auto-advance to next tab
• Response format: question -> answer format for clear output

Documentation Requirements

IMPORTANT: You MUST update the documentation when making changes to the codebase.

Update README.md when:

• Adding or modifying tool parameters/schema
• Changing installation or usage instructions
• Adding new features users need to know about
• Modifying CLI commands or flags
• Changing default behavior

Update AGENTS.md when:

• Adding or modifying files in the project structure
• Changing implementation patterns or architecture
• Adding new common tasks or workflows
• Updating build output or dependencies
• Discovering new debugging tips

This ensures both users and future agents have accurate, up-to-date information.
