✨ Key Features

🌟 UNIQUE: Universal AI Tool Configuration Hub

The killer feature no other tool offers: Juno Agent configures ALL your AI coding tools to work smarter with one command.

• One Setup, 26+ Tools: Single /setup command configures Cursor, Claude Code, Windsurf, VS Code, GitHub Copilot, and 21+ other AI tools
• Version-Specific Context: Automatically fetches current documentation for your exact dependency versions
• Smart Configuration: Creates appropriate config files (CLAUDE.md, .cursorrules, .windsurfrules, AGENTS.md) for each tool
• External Context System: Establishes external_context/ symlinks so every AI tool accesses current documentation
• MCP Server Installation: Automatically configures VibeContext MCP server across all supported tools
• Local-First Privacy: Documentation cached locally at ~/.ASKBUDI/{project}/, never sent to AI providers

Example: Instead of AI suggesting React 16 patterns for your React 18.3.1 project, every AI tool now knows your exact versions and current best practices.

🧠 REVOLUTIONARY: Complete System Prompt Control

Unprecedented AI behavior customization: Take full control over how AI models behave and respond.

• Hierarchical Override System: 7-level priority chain from global defaults to project-specific customizations
• Model-Specific Prompts: Different prompts for different models (GPT-5, Claude-4, coding subagents)
• Real-time Prompt Switching: Change AI behavior without restarting or losing context
• Template Variables: Dynamic prompts with project context, reasoning levels, and environment info
• Override Locations: Local project (.askbudi/), global user (~/.ASKBUDI/), and repository-level overrides
• Subagent Specialization: Dedicated prompts for coding subagents vs. main conversation agents

Example: Use a creative prompt for brainstorming, switch to a strict coding prompt for implementation, then use a review-focused prompt for code analysis—all in the same conversation.

🛠️ Setup Modes

Juno Agent supports both an interactive TUI setup and a fully automated headless setup. Use the mode that best fits your workflow.

Headless Mode

Run end‑to‑end setup without launching the UI. This will:

• Scan your project and initialize external_context/
• Fetch dependency docs via the Agentic Dependency Resolver
• Generate JUNO.md and IDE‑specific guide (AGENTS.md or CLAUDE.md)
• Install and verify MCP server for your editor (Claude Code via CLI; Cursor via .cursor/mcp.json)
• Produce a verification report

Prerequisites:

• Activate your virtualenv and export API keys (at minimum ASKBUDI_API_KEY)
• Optional: put keys in a .env and source it

Examples:

# Claude Code
. .venv/bin/activate
set -a && source .env && set +a
juno-agent setup --headless --editor "Claude Code" --report-file headless_report.md

# Cursor
. .venv/bin/activate
set -a && source .env && set +a
juno-agent setup --headless --editor "Cursor" --report-file headless_report.md

Outputs:

• JUNO.md, AGENTS.md or CLAUDE.md in project root
• external_context/ symlinked to ~/.ASKBUDI/<project>/external_context
• MCP config (Claude via claude mcp add; Cursor via .cursor/mcp.json)
• Verification summary printed, full report written to --report-file
• Detailed logs in app_run.log (resolver traces, MCP install, verification)

Tips:

• Ensure a requirements.txt/package.json exists so the resolver can detect dependencies
• To review resolver activity, grep app_run.log for resolver_ entries

TUI Mode

Use the Textual interface for guided setup and visibility into progress.

# Launch TUI
juno-agent

# Inside the app, start the guided setup
/setup

# Shortcuts
/setup --docs-only    # Agentic Dependency Resolver only
/setup --verify-only  # Verification only (no changes)

TUI flow mirrors headless behavior:

• Analyze project → fetch docs → generate guides → install MCP → verify
• Non‑blocking background work using Textual workers for responsiveness
• Rich status panels and step‑by‑step results

Key Bindings

• Enter: Submit message
• Ctrl+J: New line in multiline input
• Ctrl+N: Start new conversation
• F1: Show conversation history
• F2/F3: Copy message content
• Escape: Cancel current action
• Tab: Autocomplete commands

🎯 System Prompt Customization

Take complete control over AI behavior with Juno Agent's advanced system prompt management system.

Priority Chain (Highest to Lowest)

Juno Agent uses a sophisticated 7-level priority system for loading system prompts:

1. Local Project Override (./.askbudi/prompts/model_slug.md) - Highest priority
2. Global User Override (~/.ASKBUDI/prompts/model_slug.md) - User-wide settings
3. Repository Override (./prompts/overrides/model_slug.md) - Team-shared prompts
4. Model Direct Prompt (juno_config.system_prompt) - Inline definition
5. Model File Reference (juno_config.system_prompt_file) - File path reference
6. Prompt Garden Reference (juno_config.system_prompt_ref) - Built-in prompt library
7. Default Prompts - default_agent or coding_subagent fallbacks

Quick Start Examples

# Create a project-specific prompt (highest priority)
mkdir -p .askbudi/prompts
echo "You are a senior Python expert focused on clean, maintainable code." > .askbudi/prompts/gpt-5-minimal.md

# Create a global user prompt (second priority)
mkdir -p ~/.ASKBUDI/prompts  
echo "You are my personal coding assistant. Be concise and direct." > ~/.ASKBUDI/prompts/gpt-5-minimal.md

# Create a team-shared prompt (third priority)
mkdir -p prompts/overrides
echo "Follow our team's coding standards and include comprehensive tests." > prompts/overrides/gpt-5-minimal.md

Template Variables

Use dynamic variables in your prompts for context-aware AI behavior:

# Custom Development Assistant

You are an expert ${REASONING_EFFORT} assistant for ${PROJECT_CONTEXT}.

## Environment
- Working directory: ${WORKING_DIRECTORY}
- Platform: ${PLATFORM}
- Date: ${CURRENT_DATE}

## Project Context
${PROJECT_CONTEXT}

Be ${REASONING_EFFORT} in your responses and focus on ${PROJECT_CONTEXT} best practices.

Model-Specific Prompts

Customize prompts for different models and use cases:

# GPT-5 for creative brainstorming
echo "Be creative and explore multiple solutions." > .askbudi/prompts/gpt-5-high.md

# Claude-4 for code review  
echo "Focus on code quality, security, and maintainability." > .askbudi/prompts/claude-opus-4-1.md

# Coding subagents for implementation
echo "You are a focused implementation specialist." > .askbudi/prompts/coding-subagent.md
