ARTEMIS ☕📱

Autonomous Multimodal Android Agent & Mobile UI Automation Platform

ARTEMIS is a next-generation, production-grade autonomous agent and testing framework engineered for Android devices and emulators. Combining state-of-the-art multimodal Large Vision-Language Models (VLMs) with hierarchical closed-loop planning, resilient self-healing, and deep Android subsystem integration (ADB, UIAutomator2, accessibility trees), ARTEMIS enables autonomous UI navigation, robust automated testing, and intelligent device diagnostics.

✨ Key Features

• Dual-Engine Execution:
  • ARTEMIS Flash: High-speed, reactive single-agent loop for deterministic, low-latency tasks (< 35 steps).
  • ARTEMIS Pro: Multi-agent closed-loop graph orchestration (Planner \rightarrow Operator \rightarrow Failure Analyzer \rightarrow Summarizer) powered by LangGraph.
• Multimodal Perception:
  • Combined visual screenshot grounding, real-time OCR, accessibility hierarchy (XML) parsing, and dynamic video analysis.
• Resilient Locating Strategy ("Dynamic-First, Coordinate-Fallback"):
  • Prioritizes semantic IDs, XPath, and accessibility text matching to withstand UI layout drift; seamlessly falls back to calibrated absolute/relative coordinates.
• Autonomous Self-Healing:
  • Built-in failure analyzer and safety net detect blocked flows, system dialogs, app crashes, or unexpected states and auto-recover in real time.
• App Locking & Session Boundaries:
  • Restricts execution context to target application packages with automatic foreground recovery.
• Model Context Protocol (MCP) Native:
  • Exposes Android automation, state inspection, and trace querying as MCP tools for IDEs and AI orchestrators.
• Structured Pydantic Outputs:
  • Automatically parses agent observations and findings into validated Pydantic schemas.

artemis doctor

(Alternatively, copy .env.example to .env and set GEMINI_API_KEY for LLM reasoning and OCR_API_KEY for Vision perception.)

---

💡 Quick Start

Command Line Interface (CLI)

ARTEMIS installs a unified command-line tool artemis:

# 1. Environment & Device Diagnostics
artemis doctor

# 2. Interactive Setup Wizard
artemis init

# 3. Basic task execution (ARTEMIS Pro by default)
artemis run "Open YouTube and search for Lo-Fi Hip Hop"

# 4. Fast reactive profile (ARTEMIS Flash)
artemis run "Open Settings and verify Airplane Mode is turned off" --profile flash

# 5. Execute with trace recording and structured output
artemis run "Open Maps, search for coffee shops, and extract the top 3 results" \
  --test-name "coffee_search_test" \
  --traces-path "./traces" \
  --output-description '{"places": "list of shop names", "ratings": "list of rating scores"}'

# 6. Enable dynamic video recording analysis
artemis run "Play the latest video in the feed and verify playback" --with-video-recording-tools

Python SDK

Use the fluent SDK to integrate ARTEMIS into your test suites or automation workflows:

import asyncio
from pydantic import BaseModel, Field
from artemis.sdk import Agent


class VideoSearchResult(BaseModel):
    query: str = Field(..., description="The search term used")
    top_video_title: str = Field(..., description="Title of the first video result")
    channel_name: str = Field(..., description="Channel name of the first video")


async def main():
    # 1. Initialize the agent
    agent = Agent()
    await agent.init()

    try:
        # 2. Build task specification
        task = (
            agent.new_task("Search for 'Pixel 9 Pro' and get the first video details")
            .with_name("youtube_search_verification")
            .with_locked_app_package("com.google.android.youtube")
            .with_output_format(VideoSearchResult)
            .with_max_steps(50)
            .build()
        )

        # 3. Execute task
        result: VideoSearchResult = await agent.run_task(request=task)

        if result:
            print("Search Results:")
            print(f"- Query: {result.query}")
            print(f"- First Video: {result.top_video_title}")
            print(f"- Channel: {result.channel_name}")
        else:
            print("Task did not complete successfully.")

    finally:
        # 4. Clean up agent session & device connections
        await agent.clean()


if __name__ == "__main__":
    asyncio.run(main())

🔌 Model Context Protocol (MCP) Integration

ARTEMIS includes built-in MCP servers and tools to allow AI IDEs (such as Claude Desktop, Cursor, and Gemini Jetski) to control Android devices directly:

Tool Name	Description
mobile_run_task	Launches an autonomous background automation task on the connected device.
mobile_manage_task	Inspects status, terminates tasks, or injects real-time steering instructions.
mobile_get_device_state	Retrieves real-time screenshots or simplified accessibility UI trees.
mobile_inspect_trace	Inspects step-by-step screenshots, visual action overlays, and execution logs.

⚙️ Configuration Guide

All model configurations, thinking budgets, agent capabilities, and tool filtering are consolidated into a single self-explanatory configuration file: config/artemis.jsonc.

{
  // 1. Global Default Model (Applied across all sub-agents unless overridden)
  "default": {
    "provider": "google",
    "model": "gemini-3.6-flash",
    "thinking_level": "medium",
    "fallback": {
      "provider": "google",
      "model": "gemini-3.5-flash"
    }
  },

  // 2. Built-in Presets
  "presets": {
    "gemini-flagship": { "provider": "google", "model": "gemini-3.6-flash" },
    "openai-gpt4o": { "provider": "openai", "model": "gpt-4o" },
    "cost-saving": { "provider": "google", "model": "gemini-3.5-flash-lite" },
    "local-ollama": { "provider": "openai", "model": "llama3.2-vision" }
  },

  // 3. Agent & Sub-Agent Node Customizations (Optional overrides)
  "nodes": {
    // 🧠 Planner: High-level goal decomposition and strategic step planning
    "planner": { "thinking_level": "medium" },

    // 🎯 Operator: Screen perception, element interaction, and direct execution
    "operator": { "thinking_level": "medium", "include_thoughts": true },

    // 🛡️ Validator & Failure Analyzer: Self-healing and auto-recovery
    "validator_failure_analyzer": { "thinking_level": "medium" }
  },

  // 4. Agent Capabilities & Tool Filtering
  "agent": {
    "explorer_versions": { "operator": "flash", "validator": "flash" },
    "blacklisted_tools": {
      "explorer": ["ask_image_processor", "get_ocr_list", "inspect_region"]
    }
  }
}

Tip

Zero-Friction Global Change: To switch the entire platform from Gemini to GPT-4o or Claude, simply edit the "default" block once in config/artemis.jsonc. All 15 sub-agents automatically inherit the new model!

Using Non-Google LLMs

ARTEMIS supports multi-provider LLM backends via standard LangChain integrations (Google Gemini, OpenAI, OpenRouter, xAI / Grok, or Google Vertex AI).

Supported Providers & API Key Setup

Provider	Provider Key	Environment Variable	Base URL Override	Example Models
Google Gemini	google (default)	GEMINI_API_KEY	N/A	gemini-3.6-flash, gemini-3.5-flash
Google Vision OCR	ocr	OCR_API_KEY	N/A	Google Cloud Vision Text Detection
Google Vertex AI	vertexai	Google ADC (gcloud auth application-default login)	N/A	gemini-3.6-flash
OpenAI	openai	OPENAI_API_KEY	OPENAI_BASE_URL	gpt-4o, gpt-4o-mini, o3
OpenRouter	openrouter	OPEN_ROUTER_API_KEY	N/A	anthropic/claude-3.5-sonnet, meta-llama/llama-3.3-70b-instruct
xAI (Grok)	xai	XAI_API_KEY	N/A	grok-2-vision-1212, grok-beta

Note

ARTEMIS uses multimodal visual grounding (screenshots) for UI navigation. When assigning non-Google models to vision-dependent agents (such as operator), ensure the selected model supports image/vision inputs.

Switching Provider in config/artemis.jsonc

To use OpenAI or Claude globally, simply change the default section in config/artemis.jsonc:

{
  "default": {
    "provider": "openai",
    "model": "gpt-4o",
    "fallback": {
      "provider": "openai",
      "model": "gpt-4o-mini"
    }
  }
}

Custom / Local OpenAI-Compatible Endpoints (Ollama, vLLM, LocalAI)

To connect ARTEMIS to local or self-hosted LLM endpoints (e.g., Ollama or vLLM), set OPENAI_BASE_URL in .env and specify openai as the provider in your configuration:

# Route OpenAI provider calls to local Ollama / vLLM endpoint
OPENAI_API_KEY=ollama  # dummy key if required by client
OPENAI_BASE_URL=http://localhost:11434/v1

---

📊 Trace Inspection & Observability

Every task execution can record rich execution artifacts stored in ./traces/<trace_id>/:

• notes/: High-level planner notes, step summaries, and generated reports (output.md).
• screenshots/:
  • before_screenshot.jpg: Initial screen observed by the agent.
  • action_overlay_screenshot.jpg: Screen with visual tap markers (red circles) and swipe vectors (red arrows).
• logs/: Raw framework, operator, and failure analyzer diagnostic logs.

---
