#Key Highlights

• Cross-App Automation: Executes testing workflows and everyday tasks on Android from natural language instructions.
• Multimodal Targeting: Uses element indices when available, with coordinate and visual locating fallbacks for custom interfaces.
• IDE Diagnostics: Model Context Protocol (MCP) integration lets Antigravity, Claude Code, and Windsurf drive test devices and collect Logcat output and screenshots.
• Flash Execution: A reactive observe-and-act loop with asynchronous history summaries, typically 3–5s per step.
• Pro Exploration: Checks targets before individual actions and returns blocked actions to the Operator for recovery. Supports long-running exploratory and stability tests.
• AndroidWorld Results: 99%+ task completion on Google Research's AndroidWorld benchmark (100+ multi-step tasks).

#Antigravity × ARTEMIS: Autonomous Testing Workflow

Antigravity uses ARTEMIS through MCP to turn a test request into a plan, device execution, and a diagnostic report:

1. Prompt Input (Task Dispatch) Describe your test scenario and target metrics in Antigravity	2. Test Plan Generation Formulates a step-by-step test plan & architecture for review
3. Autonomous Test Execution Drives real device, navigates UI, and profiles performance	4. Final Report Delivers structured audit findings, metric tables, and raw datasets

#Quick Start

Ensure an Android device (with USB Debugging enabled) or emulator is connected. The one-click startup script will automatically:

• Install System Toolchains: Detect and auto-install ADB, scrcpy, FFmpeg, and Python (uv) dependencies.
• Mount Global MCP Server & AI Agent Rules: Prompt to automatically install global MCP configurations and the Artemis Mobile Testing Mindset (rules.md) into your AI IDEs (Antigravity, Cursor, Claude Code, Codex, Windsurf, VS Code, Cline/Roo, OpenClaw).

#macOS and Linux

# 1. Clone repo & navigate to directory
git clone https://github.com/google/artemis.git && cd artemis

# 2. One-click launch
./start.sh

#Windows PowerShell

# 1. Clone repo & navigate to directory
git clone https://github.com/google/artemis.git
cd artemis

# 2. One-click launch
.\start.bat

PowerShell does not search the current directory for executable scripts by default, so use .\start.bat without a trailing \. In Command Prompt (CMD), use start.bat instead.

Tip: Opens http://localhost:8000 in your default browser with a device connection wizard, live screen mirroring, prompt sandbox, and execution replays. You can also run directly from CLI: uv run artemis run "Open Settings, find Battery and tell me current level" --profile flash.

# Auto-install MCP server & global rules for Antigravity / Jetski:
uv run artemis mcp --install antigravity

# Or install for all supported AI IDEs (including Codex):
uv run artemis mcp --install all

#Usage Modes

_{Console Overview: ① View Switcher (Home / Workspace) · ② Model & Replay (Flash/Pro status & video replay) · ③ Live Agent Stream (Action perception, target coordinates & structured results) · ④ Prompt Dock (Natural language dispatch) · ⑤ Task Queue & Dashboard (Lifecycle & history)}

• Web Visual Test Console (uv run artemis ui): Real-time screen projection and interactive panel, supporting natural language test dispatch, live reasoning telemetry, action trajectories, and execution replay; manage server lifecycle anytime from any terminal using uv run artemis restart, uv run artemis stop, and uv run artemis status;
• MCP Server: Connects Antigravity, Claude Code, Windsurf, and other MCP clients to real devices for bug reproduction and test execution;
• Developer CLI (uv run artemis run): Direct terminal execution for automated test cases, exploratory stability inspection, or AndroidWorld benchmarks with high-fidelity structured terminal output;
• Python SDK: Integrates as a standard Python library into existing automated testing frameworks (e.g., pytest) or CI/CD pipelines with strongly typed Pydantic structured outputs and assertion support.

#What ARTEMIS Installs on Your Phone

The first task on a device installs the Artemis Accessibility Helper, a small accessibility service that reads the screen layout without taking the UiAutomation connection. Tools using UiAutomation can suppress the helper unless they enable FLAG_DONT_SUPPRESS_ACCESSIBILITY_SERVICES. You will see a collapsed "Artemis test helper is running" notification and a new entry under Settings > Accessibility; both are that helper. It listens only on the phone itself and sends nothing elsewhere.

• Pre-install it (avoids the ~3 s delay on the first task): uv run artemis helper install
• Inspect it: uv run artemis helper status / uv run artemis doctor
• Remove it any time: uv run artemis helper uninstall
• Use UIAutomator2 instead: ARTEMIS_HIERARCHY_BACKEND=uiautomator in .env
• Prevent automatic installation: ARTEMIS_HELPER_AUTO_INSTALL=false in .env

If the helper ever fails mid-task, ARTEMIS falls back to UIAutomator2 and says so in the task timeline, in mobile_manage_task status, and in the final report.

#Benchmarks: AndroidWorld (SOTA 99%+)

Artemis achieved a 99%+ completion rate on AndroidWorld, Google Research's benchmark spanning 20+ apps and 100+ multi-step tasks.

#How ARTEMIS is Architected

• Pre-Execution Checks and Action Bursts: Pro checks the target against the live UI tree and pixels before dispatching an individual action. Action bursts handle transient controls without waiting for another model turn.
• Element Locating: Combines accessibility hierarchies and OCR with visual models for custom Canvas, Compose, and Flutter interfaces.
• Shared History Compression: Flash and Pro replace older screenshots with visual summaries and compress completed steps into searchable history chunks. Context thresholds control when raw turns are replaced.

#Execution Profiles: Flash vs. Pro

ARTEMIS supports two execution profiles tailored for different automation requirements:

• Flash Profile (--profile flash): Fast and token-efficient reactive loop (~3–5s per step): one model observes the live screen, thinks, and acts, with no graph orchestration. Ideal for routine, deterministic UI tasks. The loop is unbounded by default (agent.flash.max_turns, 0 = unlimited) because history is compressed rather than capped: Flash shares the Pro session transcript ledger (session-relative T+mm:ss clock, screenshots folded into visual summaries, older steps chunked into eras and recallable on demand via search_history / replay_steps) and can query the session recording through video_analyzer. Transient UI (auto-fading control bars, toasts) is handled by chaining taps into one click_sequence. Limitations: No task plan or notes, no pre-execution safety net, no checkpoint verification or final report, and no ADB shell.
• Pro Profile (--profile pro): A planning and verification workflow (~15–40s per step), built as a multi-agent graph. A Planner maintains a living Markdown task plan with milestones and verify / assert check items; the Operator executes it with the full toolset (Explorer grounding whose flash / pro / ultra tier is a user setting per profile — pro.explorer.mode / flash.explorer_mode in config/artemis.jsonc or --explorer-pro-mode — never chosen by the agent; notes, history recall, video analysis, ADB diagnostics). Every single action passes a pre-execution Safety Net (XML-first, pixel fallback), while multi-action fast-action bursts fire back to back to beat turn latency on transient UI. A blocked or failed action opens an execution incident that stays in the Operator's context until a later action succeeds, so recovery is handled by the Operator itself with no separate repair agent. A read-only Checker verifies plan checkpoints and runs an exit final review against the original goal (--verification-level: off / final (default) / checkpoints / strict), and plan milestone edits get an advisory review. Handles 100+ step long-horizon workflows, [Loop:continuous] monitoring, and an optional written report.

#Roadmap

• Android Studio Integration: Native IDE plugin and workflow integration to enable in-editor debugging, test recording, and automated device control directly within Android Studio.
• iOS Platform Expansion: Extending multimodal perception and mobile automation to iOS devices and simulators.
• On-Device Lightweight VLMs: Local execution with lightweight edge vision models for low-latency, privacy-first automation.
• Real-time Duplex Voice Interaction: Voice-driven task dispatch with real-time conversational control and interruption handling.
