A complete toolset that enables maximum level of human-(intention-)in-the-loop onto any long-running, multi-agentic AI workflows (like Ralph Loop!).

Single/multiple choice questions, custom options, multi-agent interoperability, question queueing, question rejection with explanation, elaboration requesting, quick recommendations auto-selection, themes, native OS notification, terminal progress bar, multi-language support, agent skills support... and more. You can customize them all too!

Can be used via MCP server / OpenCode plugin / Agent Skills.

What does it do?

AUQ lets your AI assistants ask clarifying questions consisting of multiple-choice/single-choice questions (with an "Other" option for custom input / rejection / ask for elaboration) while coding or working, and wait for your answers through a separate CLI window without messing up your workflow.

This lets you inject your intent into long-running autonomous AI tasks—no more switching windows or babysitting AIs. Turn on the CLI anytime, even remotely via SSH!

A no no fun background story

In AI-assisted coding, guiding LLMs to ask clarifying questions have been widely recognized as a powerful prompt engineering technique to overcome LLM hallucination and generate more contextually appropriate code [1].

On October 18th, Claude Code 2.0.21 introduced an internal AskUserQuestion tool. Inspired by it, I decided to build a similar tool that is:

• Integration-flexible - Works with MCP clients (Claude Desktop, Cursor, etc.) and has official OpenCode plugin support
• Non-invasive - Doesn't heavily integrate with your coding CLI workflow or occupy UI space
• Multi-agent friendly - Supports receiving questions from multiple agents simultaneously in parallel workflows

Setup Instructions

🚀 Install CLI Tool

First, install the AUQ CLI:

Global Installation (Recommended)

Bun (recommended — required for default OpenTUI renderer)

bun add -g auq-mcp-server

npm

npm install -g auq-mcp-server

pnpm

pnpm add -g auq-mcp-server

yarn

yarn global add auq-mcp-server

> Note: Bun is recommended for the default OpenTUI renderer. When installed via npm/pnpm/yarn, the shell wrapper auto-detects Bun at runtime. If Bun is not available, it falls back to Node.js with the legacy Ink renderer.

Local (Project-specific) Installation

# Install in your project
bun add auq-mcp-server

Sessions are stored globally regardless of installation method. See [Troubleshooting](#troubleshooting) for session locations.

🔌 Integrate to your AI

AUQ supports multiple AI environments. Choose between OpenCode plugin and MCP server.

Option A: MCP Server

> Note: Due to differences in how some MCP clients are implemented, AUQ may be forcibly cancelled in tools that do not allow extending the global MCP timeout. If that's the case, consider using [Agent Skills](#option-c-agent-skills-experimental). Use [OpenCode plugin](#option-b-opencode-plugin) if you use OpenCode.

Cursor

[](https://cursor.com/en-US/install-mcp?name=ask-user-questions&config=eyJlbnYiOnt9LCJjb21tYW5kIjoibnB4IC15IGF1cS1tY3Atc2VydmVyIHNlcnZlciJ9)

Claude Code

Method 1: Using CLI (Recommended)

claude mcp add --transport stdio ask-user-questions -- bunx -y auq-mcp-server server

> Note: npx also works if you prefer npm.

Method 2: Manual Configuration

Add to .mcp.json in your project root (for team-wide sharing):

{
  "mcpServers": {
    "ask-user-questions": {
      "type": "stdio",
      "command": "bunx",
      "args": ["-y", "auq-mcp-server", "server"]
    }
  }
}

Or add to ~/.claude.json for global access across all projects.

Note: Replace bunx if you don't use bun.

Verify setup: Type /mcp in Claude Code to check server status.

Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.ask-user-questions]
command = "bunx"
args = ["-y", "auq-mcp-server", "server"]
tool_timeout_sec = 99999  // Extend timeout for long sessions

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "ask-user-questions": {
      "command": "bunx",
      "args": ["-y", "auq-mcp-server", "server"]
    }
  }
}

> Replace bunx if you don't use bun.

Restart Claude Desktop after saving.

Option B: OpenCode Plugin

Direct integration for OpenCode users. Adds working directory viewability feature exclusively.

Configuration

Add to opencode.json:

{
  "plugin": ["@paulp-o/opencode-auq@latest"]
}

Option C: Agent Skills (Experimental)

Usage with Skills-Compatible Agents

Copy the skills/ask-user-questions/ folder to your agent's skills directory.

Limitations

This skill guides the AI to use AUQ CLI's hidden command, auq ask with raw JSON as parameters. Unlike MCP or proper tool harness systems, malformed JSON healing/schema enforcement aren't supported natively; therefore a less capable model could struggle to call properly.

---

💻 Usage

Starting the CLI tool

auq       # if installed globally (bun add -g)
# bunx auq
# npx auq

Start by defining your workflow to use AUQ tool for clarifying questions, on AGENTS.md (or CLAUDE.md), like:

Whenever you need clarification on what you are working on, never guess, and call AUQ(ask-user-questions).

When the AI asks questions, you'll see them appear in the AUQ TUI. Answer them at your convenience.

Renderer Selection

AUQ supports two terminal rendering engines:

| Renderer | Description | Status | | --------------------- | --------------------------------------------------- | ------------------- | | OpenTUI (default) | Native Zig-based renderer with improved performance | Stable (requires Bun) | | ink | React-based terminal renderer | Fallback (Node.js) |

OpenTUI is the default renderer and requires Bun runtime. When Bun is unavailable, AUQ automatically falls back to the Ink renderer.

To force a specific renderer, set one of the following (in priority order):

1. Environment variable (highest priority):

``bash AUQ_RENDERER=ink auq # force ink AUQ_RENDERER=opentui auq # force opentui ``

1. Config file (.auqrc.json):

``json { "renderer": "ink" } ``

1. CLI command:

``bash auq config set renderer ink ``

> Note: OpenTUI provides native CJK character support, built-in markdown rendering with syntax highlighting, and mouse support. The shell wrapper (bin/auq) auto-detects Bun at runtime.

Markdown rendering in question prompts

Question prompts now support Markdown formatting in the prompt text.

• Supported: bold, italic, ~~strikethrough~~, inline code, links, and fenced code blocks (with syntax highlighting)
• Links render as text (url) for broad terminal compatibility
• Code blocks use theme-aware colors (background/text/border)
• Always enabled (no configuration needed)
• Plain text prompts pass through unchanged
• Graceful fallback: if Markdown parsing fails, the raw text is shown

> Note: AUQ is an unopinionated tool and doesn't include prompts on HOW AI should leverage it. It is expected that you do your own prompt engineering to make the most out of it in your own workflows. > I personally enjoy prompting it to ask at least 30 questions repeatedly before action!

Recommended Setups

It is recommended to disable the built-in questioning tool in your harness (like the question tool in OpenCode or AskUserQuestion in Claude Code) to avoid AI from mixing them up.

📋 Full CLI Reference

CLI Commands

AUQ provides headless CLI commands for managing sessions and configuration without the TUI. Run auq --help for the complete reference.

Answer Sessions

auq answer  --answers '{"0": {"selectedOption": "option1"}}'
auq answer  --answers '{"0": {"selectedOptions": ["A", "B"]}}'  # multi-select
auq answer  --answers '{"0": {"customText": "free text"}}'  # custom text
auq answer  --reject --reason "Not applicable"
auq answer  --answers '...' --force  # abandoned session
auq answer  --answers '...' --json

Manage Sessions

auq sessions list                    # pending sessions (default)
auq sessions list --stale             # stale sessions only
auq sessions list --all               # all sessions
auq sessions show          # session details
auq sessions dismiss       # dismiss stale session
auq sessions dismiss  --force
auq sessions list --limit 10 --page 2 # pagination
auq sessions list --json

Session History

auq history                           # list session history
auq history --all                     # include abandoned
auq history --unread                  # unread only
auq history --search "deploy"          # search
auq history --limit 10 --page 2       # pagination
auq history show           # full Q&A detail
auq history --json

Fetch Answers (Programmatic)

auq fetch-answers --unread            # list unread answered sessions
auq fetch-answers          # fetch specific session
auq fetch-answers  --blocking  # wait until answered
auq fetch-answers --limit 10 --page 2
auq fetch-answers --json

Configuration

auq config get                        # view all
auq config get staleThreshold         # view specific
auq config set staleThreshold 3600000 # set local
auq config set staleThreshold 3600000 --global  # set global

Update

auq update        # interactive update check
auq update -y     # skip confirmation

Pagination

List commands (sessions list, history, fetch-answers) support:

• --limit — Max items per page (default: 20)
• --page — Page number (default: 1)

🌍 Environment Variables

| Variable | Description | | -------------------- | ------------------------------------------------ | | AUQ_RENDERER | Override renderer ("ink" or "opentui") | | AUQ_SESSION_DIR | Custom session storage directory | | XDG_CONFIG_HOME | Custom config directory (default: ~/.config) | | NO_UPDATE_NOTIFIER | Set to "1" to disable update checks |

Stale Session Detection

Sessions that remain unanswered longer than the configured threshold are marked as "stale" (potentially orphaned). This helps identify sessions where the AI may have disconnected or timed out.

• Visual indicators: Stale sessions show a ⚠ warning icon and yellow highlighting in the TUI
• Toast notifications: A notification appears when a session becomes stale (configurable)
• Grace period: Interacting with a stale session provides a 30-minute grace period
• Configurable threshold: Default is 2 hours (7,200,000ms)

---

Abandoned Session Handling

When an AI client disconnects, associated sessions are marked as "abandoned". These sessions:

• Remain visible in the TUI with a red indicator
• Show a confirmation dialog before answering ("AI가 disconnect되었습니다")
• Can still be answered via CLI with the --force flag
• Are detectable via auq sessions list --all

---

Auto-Update

AUQ automatically checks for updates and keeps itself up to date.

How it works

• All updates (patch, minor, major): A fullscreen overlay is shown with changelog and options to update, skip, or defer.
• Update checks: Run on every TUI launch (no delay/cache).
• CLI notification: When running non-TUI commands, a one-line update notification is shown if a newer version is available.

Manual update

Run auq update to manually check for and install updates:

auq update        # Interactive update check
auq update -y     # Skip confirmation prompt

Disabling update checks

Disable automatic update checks via config:

auq config set updateCheck false

Or set the environment variable:

NO_UPDATE_NOTIFIER=1 auq ask "question"

Update checks are automatically disabled in CI environments (CI=true).

The auq update command always works regardless of these settings.

Theme System

AUQ supports 16 built-in color themes with automatic persistence. Press Ctrl+T to cycle through themes.
