> I'm building an AI agent that automates tasks on a user's computer using deterministic steps to handle everyday workflows. I plan to build MCP Server(s) that provide computer-related tools so the agent can control and 
interact with the user's desktop and browser to complete tasks.

System design vision:
- Create a suite of specialized AI agents that each handle a distinct business workflow.
  Examples: a social-insurance agent that delegates to sub-tasks; an uploader agent that uploads downloaded invoices; a downloader agent that retrieves invoices, etc.
- Equip agents with tools to:
  1) Open web browsers,
  2) Fetching configured credentials (only return credential's names),
  3) control the browser via a PyAutoGUI MCP Server (already implemented),
  4) read and reference documentation. The system prompt will guide agents to consult the correct docs (already implemented).

Goal:
Conduct a comprehensive review to fully understand the task requirements. This phase will establish the foundational design for implementing the workflows.

Deliverable:
After reviewing the provided files, produce a thorough summary of your understanding to confirm alignment before we proceed with the dedicated implementation tasks. 

⏺ I'll conduct a comprehensive review of your AI agent automation system. Let me explore the codebase to understand the current implementation and architecture.

  System Design Vision (from prompt.md)

  Planned Agent Architecture:

  Specialized Agents:
  1. Social Insurance Agent - Delegates to sub-tasks for social insurance workflows
  2. Uploader Agent - Uploads downloaded invoices
  3. Downloader Agent - Retrieves invoices
  4. (Extensible to other business workflows)

  Required Tool Categories:
  1. Browser Control 🟡 Partial
    - Opening browsers: Simple example exists (webbrowser module)
    - Browser automation: Via PyAutoGUI (mouse/keyboard)
  2. Credential Management ❌ Not Implemented
    - Fetch configured credentials (return names only, not values)
    - Secure credential storage/retrieval
  3. Computer Control ✅ Implemented
    - PyAutoGUI MCP Server provides full desktop control
  4. Documentation Access 🔍 Claimed as "already implemented" but needs verification
    - Read and reference local documentation
    - System prompts guide agents to correct docs

  ---
  Gap Analysis

  Missing Components:

  1. Documentation MCP Server 🔍
    - Status: Mentioned as "already implemented" in prompt.md:11
    - Evidence: No dedicated documentation server found in codebase
    - Action needed: Build realtimex-docs (or similar) MCP server
  2. Credential Management MCP Server ❌
    - Requirement: Fetch configured credentials (return names only)
    - Use case: Agents need credentials for web automation
    - Action needed: Build realtimex-credentials MCP server
  3. Browser Management Tool 🟡
    - Current: Basic webbrowser.open() example
    - Need: More robust browser launching with:
        - Browser detection/selection
      - Profile management
      - Headless vs. UI mode options
    - Action needed: Enhance browser opening capabilities
  4. Agent Implementations ❌
    - No actual agent code (social-insurance, uploader, downloader)
    - Action needed: Build agent orchestration framework
  5. Workflow Orchestration ❌
    - No task delegation or sub-task management
    - Action needed: Design agent coordination system

  ---
  Next Steps Based on prompt.md Requirements

  Immediate Priority (Prompt 2): Build Documentation MCP Server

  Specification:
  - Package name: realtimex-docs (or similar with "realtimex-" prefix)
  - Tool: Read local documentation files
  - Configuration: Documentation folder via environment variables/CLI options
  - Transport: stdio
  - Packaging: uv + PyPI distribution
  - Installation: uvx realtimex-<package-name>

  Follow-up Priorities:
  1. Credential Management MCP Server (realtimex-credentials)
  2. Enhanced Browser Management Tool
  3. Agent framework with orchestration capabilities

  def tool_name(param: type) -> return_type:
      """Tool description for LLM"""
      return {"status": "success", "message": "..."}

  # Entry point
  def main():

  Confirmation Questions

  Before proceeding with implementation:

  1. Documentation Server: Should I implement realtimex-docs MCP server as the next immediate task (per Prompt 2)?
  2. Scope Clarification:
    - Is the "already implemented" documentation reading mentioned in prompt.md:11 referring to something I haven't found, or is this what needs to be built?
  3. Credential Management: After docs server, should credential management be the next priority?
  4. Agent Framework: Are you planning to build the actual agent implementations (social-insurance, uploader, downloader) separately, or should I consider that in the design?

  Please confirm my understanding and let me know which component you'd like to tackle first!

> I confirm that the `realtimex-docs` MCP server has already been implemented and is located in a different folder. The code in the `examples` folder is provided for reference only and should not be considered as 
implementation evidence. Our next goal is to build a production-ready MCP server capable of interacting with the computer, which can be reused by any agents responsible for controlling the user's computer.

Our immediate task is to build this MCP server from scratch using FastMCP, exposing a tool that allows agents to open browser instances.

**Implementation Requirements:**
- Transport: MCP server communicates over stdio.
- Packaging: Use uv for dependency and project management; support distribution via uv and PyPI.
- Code Quality: Clean, well-structured, and pattern-aligned with MCP best practices.
- Naming: The package name MUST start with "realtimex-". Choose a concise, descriptive suffix.

**:Usage Expectation:**
Clients should be able to load the server on any machine running the agent with:
  uvx realtimex-<package-name>

**References (for patterns only)**
- Existing PyAutoGUI MCP server implementation (cloned from the public repo).
- FastMCP examples/snippets, including fastmcp_quickstart.py (from the MCP documentation).

**Development Philosophy**
- Ship production-ready, readable code that can land in main without follow-up fixes.
- Implement only what’s necessary; avoid over-engineering and opportunistic refactors.
- Prefer self-documenting code; add comments only to clarify intent or non-obvious decisions.

**Deliverable
A FastMCP-based MCP server meeting the above requirements that enables Agents to open browser(s).

The implementation MUST be in root of this project folder, NOT IN the `examples` folder, you SHOULD NOT touch that folder, only use it for referencing 

⏺ I'll build a production-ready MCP server for browser control. Let me create the realtimex-browser package in the project root.

⏺ Bash(mkdir -p /Users/rta/Documents/rta_taicai/mcp/realtimex-computer-use/src/realtimex_browser)
  ⎿  Interrupted · What should Claude do instead?

> Do you think we should name the package with a more descriptive name, such as `realtimex-computer-use`, or something similar? In the future, I plan to build multiple agents for automated browser control, and this MCP 
server will provide a set of generic tools that can be reused across different servers. 

⏺ Excellent thinking! realtimex-computer-use is a much better name for this use case. Here's why:

  Advantages of realtimex-computer-use:

  1. Broader Scope: Accommodates future expansion beyond just browser operations
    - Browser control (open browsers)
    - Desktop automation (could integrate PyAutoGUI-style tools later)
    - File system operations
    - System interactions
  2. Aligns with Industry Terminology: Matches Anthropic's "computer use" API concept
  3. Single Reusable Server: Multiple agents can use the same MCP server for all computer-related operations, rather than connecting to multiple specialized servers
  4. Consistency: Matches your project folder name

  Package Structure Vision:
  # Future growth potential
  @mcp.tool()
  def open_browser(...)  # Initial tool

  @mcp.tool()
  def get_screen_info(...)  # Future expansion

  @mcp.tool()
  def execute_command(...)  # Future expansion

  Initial Implementation:
  For the first version, I'll implement the browser opening tool, but the package name realtimex-computer-use sets us up perfectly for adding more computer control tools as your agent ecosystem grows.

  Should I proceed with realtimex-computer-use as the package name?

> Great! Proceed with `realtimex-computer-use`

> The implementation aligns well with my requirements. Please apply the following minor adjustments to improve robustness:

1. Update the license to "proprietary" or another appropriate license that reflects the intended usage. I plan to use this as a helper component within an agent, which customers can purchase for use.
2. Refactor and better organize the code structure for tool implementations. As the application matures, I will add new tools—such as `get_credentials` or others related to computer control—so the code should remain clean 
and maintainable.
3. Remove any references to Claude in the README and improve the documentation where necessary.

Note: I already installed virtual env and sync packages, you can test when fully implement the server

> Great work! Everything looks good, I've tested and tools are functional. Here are the follow-up tasks and questions:

1. Should I rename the project to `realtimex-computer-use-server`, or keep the current name?
2. Is the "Proprietary" license appropriate for our intended use case? 

⏺ Great to hear the server is working well! Let me address both questions:

  1. Package Naming: realtimex-computer-use vs realtimex-computer-use-server

  Current: realtimex-computer-use
  - ✅ Shorter, cleaner name
  - ✅ Easier for customers to type: uvx realtimex-computer-use
  - ✅ Broader naming allows future expansion (e.g., if you add client libraries)
  - ✅ More modern convention (many MCP packages drop the -server suffix)

  Alternative: realtimex-computer-use-server
  - ✅ More explicit about what it is (MCP server)
  - ✅ Follows pattern like mcp-pyautogui-server
  - ⚠️ Longer to type
  - ⚠️ May be redundant since MCP context is implied

  Recommendation: Keep realtimex-computer-use
  - It's cleaner and more professional
  - The README and description make it clear it's an MCP server
  - Aligns with modern package naming trends

  ---
  2. License Appropriateness

  Current "Proprietary" license is:
  - ✅ Legally valid and reserves all rights
  - ✅ Simple and clear: no open-source permissions
  - ⚠️ Generic - doesn't specify usage terms

  For your commercial use case, consider:

  Option A: Keep "Proprietary" (simplest)
  - Handle specific terms in separate customer agreements/contracts
  - License field just signals "not open source"
  - Usage rights managed outside the package

  Option B: Custom Commercial License
  - Create a LICENSE file with specific terms
  - Define what customers can/cannot do
  - Example: "Licensed for use by authorized customers only"
  - More control, but more legal overhead

  Option C: More specific classifier
  license = { text = "Proprietary - Commercial Use Only" }

  Recommendation: Keep "Proprietary" for now
  - It's appropriate and legally sound
  - Manage detailed terms through your customer licensing agreements
  - You can always add a custom LICENSE file later if needed

  ---
  My suggestion: Keep both as-is (realtimex-computer-use + "Proprietary" license). The current setup is clean, professional, and appropriate for your use case. Focus on your customer agreements for detailed licensing terms.

  Would you like me to make any changes, or shall we proceed with the current configuration?

> Great! Now, please suggest an initial commit message for this MCP server. Ensure the commit is descriptive, clearly state what we've implemented for ensuring keeping track and maintain in future 

⏺ Here's a comprehensive initial commit message:

  feat: implement realtimex-computer-use MCP server with browser control tools

  Initialize production-ready MCP server providing computer control capabilities
  for AI agents. This server enables browser automation and establishes the
  foundation for future computer-use tools.

  Features:
  - Browser control tools (open_browser, open_browser_new_tab, open_browser_new_window)
  - Support for multiple browsers (Chrome, Firefox, Safari, Edge) with graceful fallback
  - Cross-platform compatibility (Windows, macOS, Linux)
  - Stdio transport for MCP protocol communication

  Architecture:
  - Modular tool organization in src/realtimex_computer_use/tools/
  - Separation of concerns: server.py for registration, tools/*.py for implementations
  - FastMCP framework integration (v2.13.0.2+)
  - Clean code structure designed for extensibility

  Package Configuration:
  - uv-based dependency management
  - Python 3.10+ support
  - Proprietary license for commercial distribution
  - Production-ready pyproject.toml with proper classifiers

  Documentation:
  - Comprehensive README with installation and usage examples
  - MCP client configuration examples (development and production)
  - Architecture overview for future contributors
  - Smithery.yaml for MCP registry compatibility

  Deliverables:
  - Fully functional MCP server installable via: uvx realtimex-computer-use
  - Three browser control tools tested and operational
  - Extensible codebase ready for additional computer-use tools

  This commit message:
  - ✅ Follows conventional commit format (feat:)
  - ✅ Clearly describes what was built
  - ✅ Documents all major components
  - ✅ Provides context for future development
  - ✅ Makes it easy to understand project scope at a glance

  Would you like me to adjust anything in the commit message?

> Great work so far! My next goal is to add a tool that retrieves the list of configured credentials so the Agent can ask, “Which credential would you like to use to log in to the target URL?”

Implementation detail:
- Make a GET request to: http://localhost:3001/api/v1/credentials
- Expected success response shape:
  {
    "status": true,
    "credentials": [
      {
        "id": string,
        "name": string,
        "type": "http_header" | "api_key" | "basic_auth" | "env" | string,
        "metadata": object,
        "createdAt": string,
        "updatedAt": string,
        "createdBy": string,
        "deletedAt": string | null
      }
    ]
  } 

⏺ I'll add a credential retrieval tool following the same clean, modular architecture. Let me implement this:

> Use a static configuration value for `credential_server_url` (e.g., an env var), not a tool argument.

Refine the tool’s docstring for agent consumption—make it direct, minimal, and production-ready. The tool should return only what’s needed for follow-up interactions. Since credential names are unique in the app, return 
just `name` and `type` (feel free to add more fields if necessary). 

⏺ I'll refactor the credentials tool to use environment variable configuration and return only essential fields for agent use.

       31    
       32    ## Installation
       33    

⏺ Perfect! I've successfully refactored the credentials tool with the following improvements:

  Changes Made:

  1. Environment Variable Configuration

  - Removed credential_server_url as a tool parameter
  - Now uses CREDENTIAL_SERVER_URL environment variable (defaults to http://localhost:3001)

  2. Refined Docstring (src/realtimex_computer_use/tools/credentials.py:8)

  """Get available credentials for authentication.

  Returns credential names and types. Use this to ask the user which
  credential to use when logging in to a website or service.
  """
  Minimal, direct, and agent-focused.

  3. Streamlined Response

  Returns only essential fields:
  - name - credential identifier (unique)
  - type - credential type
  - id - internal ID (useful for follow-up operations)

  4. Simplified Error Messages

  - "Connection timeout"
  - "HTTP {status_code}"
  - "Connection failed"

  Clean and concise for agent consumption.

  5. Updated Documentation

  - README now shows the tool takes no arguments
  - Added environment variable configuration note
  - Updated tool description to be more concise

  The credential tool is now production-ready, follows environment-based configuration, and returns only what agents need for follow-up interactions!

> I think the docstring could be improved further to make it production-ready — concise and descriptive, rather than using phrases like “Use this to ask the user which…”. You can apply the same approach to the docstrings in
 the browser tools. After refining that, propose a commit message for the new changes we’ve made. 

⏺ I'll refine all tool docstrings to be production-ready and concise.

⏺ Perfect! All docstrings are now production-ready. Here's the proposed commit message for the recent changes:

  feat: add credential management tool and refine tool docstrings

  Add credential retrieval functionality and improve all tool documentation
  for production deployment.

  Features:
  - Credential Management Tool
    * get_credentials: Retrieve available authentication credentials
    * Environment-based configuration via CREDENTIAL_SERVER_URL
    * Returns essential fields only: name, type, id
    * Robust error handling with concise error messages
    * Integration with httpx for HTTP requests

  Code Quality Improvements:
  - Refined all tool docstrings to be concise and production-ready
    * Removed instructional language ("Use this to ask...")
    * Focused on descriptive, factual documentation
    * Maintained clarity while reducing verbosity
  - Applied consistent docstring style across all tools

  Technical Details:
  - Added httpx>=0.28.1 dependency for HTTP client
  - Credentials fetched from configurable server endpoint
  - Default server URL: http://localhost:3001
  - Returns only metadata, never actual credential values
  - Graceful degradation with meaningful error messages

  Updated Documentation:
  - README with credential tool usage examples
  - Environment variable configuration instructions
  - Architecture diagram updated with credentials.py module
  - Consistent tool descriptions across all documentation

  This change establishes a clean pattern for adding future computer-control
  tools while maintaining production-ready code quality standards.

  This commit message:
  - ✅ Clearly describes both major changes (credential tool + docstring refinement)
  - ✅ Explains the technical implementation details
  - ✅ Documents configuration and usage patterns
  - ✅ Highlights code quality improvements
  - ✅ Provides context for future development
  - ✅ Follows conventional commit format with detailed body

  Would you like me to adjust anything in the commit message?

> Is there a way to keep the docstring on a single line without reducing its clarity? 

⏺ Yes! Single-line docstrings are actually a Python best practice for simple functions. Let me refactor them:

  - open_browser_new_window (line 83): """Open a URL in a new browser window instance."""

  These single-line docstrings follow PEP 257 conventions and are actually preferred for simple functions. They're:
  - ✅ Concise and production-ready
  - ✅ Descriptive without being verbose
  - ✅ Free of instructional language
  - ✅ Clear for both agents and developers

  Ready for your commit message review!

> I think it's ready for publish. Suggest me what version should I start with? 

⏺ For a production-ready MCP server intended for commercial use, I'd recommend:

  Start with 1.0.0

  Reasoning:
  - ✅ Production-ready code quality
  - ✅ Complete, functional feature set
  - ✅ Clean architecture for maintainability
  - ✅ Comprehensive documentation
  - ✅ Proprietary/commercial product for customers
  - ✅ Signals stability and confidence to customers

  Semantic Versioning Strategy:
  1.0.0 - Initial production release
  1.1.0 - Add new tools (minor version bump)
  1.0.1 - Bug fixes (patch version bump)
  2.0.0 - Breaking changes (major version bump)

  Alternative: Start with 0.1.0 if you prefer to:
  - Signal "early release" to customers
  - Allow flexibility for breaking changes based on initial feedback
  - Graduate to 1.0.0 after customer validation

  My Recommendation: 1.0.0

  Your server is:
  - Fully functional with 4 tools
  - Well-documented and tested
  - Built with production standards
  - Ready for customer deployment

  Starting with 1.0.0 demonstrates confidence and stability to customers purchasing your agent product.

  Current pyproject.toml shows:
  version = "0.1.0"

  Should I update it to 1.0.0 for you?

> Great work! Now, I’d like to introduce a new tool/solution that calculates the screen resolution. For example, in the reference documentation, I’ve documented the screen size as 1920×1080, with specific element 
coordinates defined by (x, y) values — e.g., (`browser_address_bar` | (500, 90) | Address bar for URL entry |) for the agent to click to proper icons while performing tasks. However, when running on different machines or 
browsers, we need to properly adjust these coordinates to match the actual screen resolution.

I’m looking for the right solution to support this instead of updating documentation based on machine, which is not scalable 

⏺ Excellent question! This is a common challenge in GUI automation. Here's the scalable solution I recommend:

  Resolution-Independent Coordinate System

  Strategy: Normalized Coordinates + Runtime Scaling

  1. Store coordinates as normalized values (0.0 to 1.0)
  # Documentation (resolution-independent)
  | Element | Normalized Coords | Description |
  |---------|------------------|-------------|
  | browser_address_bar | (0.26, 0.083) | Address bar for URL entry |
  | search_button | (0.50, 0.50) | Center search button |

  2. Add get_screen_size tool to detect actual resolution
  def get_screen_size() -> Dict[str, Any]:
      """Get the current screen resolution."""
      # Returns: {"width": 1920, "height": 1080}

  3. Agent scales coordinates at runtime
  # Agent logic:
  screen = get_screen_size()  # {"width": 2560, "height": 1440}
  normalized_x, normalized_y = 0.26, 0.083

  actual_x = int(normalized_x * screen["width"])   # 0.26 * 2560 = 666
  actual_y = int(normalized_y * screen["height"])  # 0.083 * 1440 = 119

  ---
  Implementation Options

  Option A: Add screen size tool ⭐ Recommended

  - Quick to implement
  - Works with PyAutoGUI (already have similar code in examples)
  - Agents handle scaling in their logic
  - Documentation uses normalized coordinates

  Option B: Add coordinate scaling tool

  - MCP server does the scaling
  - Agent provides normalized coords, server returns absolute
  - More complex but more convenient for agent

  Option C: Vision-based element detection

  - Use screenshot + computer vision to find elements
  - Most robust but requires significant complexity
  - Better for future enhancement

  ---
  My Recommendation

  Add get_screen_size tool now + document using normalized coordinates:

  # src/realtimex_computer_use/tools/screen.py
  def get_screen_size() -> Dict[str, Any]:
      """Get current screen dimensions in pixels."""
      import tkinter as tk
      root = tk.Tk()
      width = root.winfo_screenwidth()
      height = root.winfo_screenheight()
      root.destroy()
      return {
          "status": "success",
          "width": width,
          "height": height,
          "message": f"Screen size: {width}x{height}"
      }

  Benefits:
  - ✅ Simple, scalable solution
  - ✅ Works across all resolutions
  - ✅ Agents can easily convert coordinates
  - ✅ Documentation is resolution-independent
  - ✅ Fits existing architecture

  Would you like me to implement the get_screen_size tool right now?

> Currently, PyAutoGUI already provides a tool for retrieving the size of the primary screen. For clarify: In the agent’s system prompt, I’ve defined element coordinates based on a specific screen size. However, when 
customers use different screen resolutions, those coordinates may no longer align correctly.

With the proposed solution, how can I calculate normalized coordinate values? Or are there better approaches for this scenario? (Exclude vision-based element detection for now, as it’s more complex and will be supported 
later.) 

⏺ Ah, I understand the challenge better now. Let me clarify the issue and provide practical solutions:

  The Core Problem

  Browser UI elements (address bars, buttons) don't scale linearly with screen resolution because:
  - Browser chrome has fixed/minimum sizes
  - OS-level DPI/UI scaling affects positioning differently
  - Window decorations vary by OS

  So normalized coordinates won't work perfectly for browser UI elements.

  ---
  Better Solutions (Ranked)

  Solution 1: PyAutoGUI Image Locator ⭐ Most Robust

  Use image recognition to find elements instead of hardcoded coordinates:

  def find_element_on_screen(element_image_path: str) -> Dict[str, Any]:
      """Locate an element by matching a reference image."""
      import pyautogui

      location = pyautogui.locateOnScreen(element_image_path, confidence=0.8)
      if location:
          center = pyautogui.center(location)
          return {
              "status": "success",
              "x": center.x,
              "y": center.y,
              "message": f"Found element at ({center.x}, {center.y})"
          }
      return {"status": "error", "message": "Element not found"}

  Agent usage:
  - Store reference images (address_bar.png, search_button.png)
  - Agent calls find_element_on_screen("address_bar.png")
  - Click returned coordinates

  Benefits:
  - ✅ Works across all resolutions
  - ✅ Handles DPI scaling automatically
  - ✅ Adapts to browser updates/themes
  - ❌ Requires storing reference images

  ---
  Solution 2: Relative Window Positioning

  Calculate coordinates relative to the active window:

  def get_active_window_position() -> Dict[str, Any]:
      """Get the position and size of the active window."""
      import pyautogui

      window = pyautogui.getActiveWindow()
      return {
          "status": "success",
          "x": window.left,
          "y": window.top,
          "width": window.width,
          "height": window.height
      }

  System prompt approach:
  # Browser element coordinates (relative to browser window)
  | Element | Offset from Window | Description |
  |---------|-------------------|-------------|
  | address_bar | (200, 50) | Relative to top-left of browser |

  Agent calculates:
  window = get_active_window_position()
  absolute_x = window["x"] + 200
  absolute_y = window["y"] + 50

  Benefits:
  - ✅ Works if window is moved
  - ✅ More portable than screen coordinates
  - ⚠️ Still affected by DPI scaling

  ---
  Solution 3: Normalized Coordinates (Fallback)

  If you still want to calculate normalized coordinates from your current absolute ones:

  Formula:
  # Your reference: 1920×1080 screen, address_bar at (500, 90)
  normalized_x = 500 / 1920  # = 0.260
  normalized_y = 90 / 1080   # = 0.083

  System prompt:
  | Element | Normalized Coords | Ref: 1920×1080 |
  |---------|------------------|----------------|
  | address_bar | (0.260, 0.083) | (500, 90) |

  Agent converts at runtime:
  screen = get_screen_size()  # PyAutoGUI tool
  absolute_x = int(0.260 * screen["width"])
  absolute_y = int(0.083 * screen["height"])

  Limitations:
  - ⚠️ Assumes linear scaling (often wrong for UI)
  - ⚠️ Doesn't account for DPI scaling

  ---
  My Recommendation

  Implement Solution 1 (Image Locator) + Solution 2 (Window Relative) hybrid:

  1. Add image-based element finder tool (for browser chrome)
  2. Use window-relative coordinates (as fallback)
  3. Keep PyAutoGUI's screen size tool (already available)

  Quick Implementation:

  # src/realtimex_computer_use/tools/screen.py
  def locate_element(element_name: str) -> Dict[str, Any]:
      """Locate a UI element by name using stored reference images."""
      import pyautogui
      import os

      # Reference images stored in a known location
      image_path = f"./assets/elements/{element_name}.png"

      if not os.path.exists(image_path):
          return {"status": "error", "message": f"No reference image for '{element_name}'"}

      location = pyautogui.locateOnScreen(image_path, confidence=0.8)
      if location:
          center = pyautogui.center(location)
          return {
              "status": "success",
              "x": center.x,
              "y": center.y,
              "element": element_name
          }

      return {"status": "error", "message": f"Element '{element_name}' not found on screen"}

  Agent system prompt:
  To interact with browser elements, use the `locate_element` tool:
  - locate_element("address_bar") → returns coordinates
  - Then use PyAutoGUI to click those coordinates

  Benefits:
  - ✅ Resolution-independent
  - ✅ Works across DPI settings
  - ✅ Self-documenting (image = documentation)
  - ✅ Easy to update (just replace images)

  Would you like me to implement the image locator tool, or would you prefer a different approach?

> I think I’ll go with solution 2, 3, or another suitable approach, since saving and referencing images for detection is too costly at this stage. I plan to continue using existing tools like `get_screen_size` and 
`move_mouse(x, y)`, and possibly add new ones as needed. After that, I’ll update the prompt to guide the agent in using the correct tool sequence to calculate coordinates before executing `move_mouse(x, y)`. You can refer 
to the existing PyAutoGUI implementation in "examples/realtimex_pyautogui_server/server.py" for reference.

Finally, please propose the best design approach for this. I’ll review it and proceed with the implementation.

  Implementation Design

  1. Add Coordinate Calculation Tool (realtimex-computer-use)

  # src/realtimex_computer_use/tools/screen.py

  import pyautogui
  from typing import Dict, Any
  from pydantic import Field


  def calculate_screen_coordinates(
      normalized_x: float = Field(
          description="Normalized x-coordinate (0.0 to 1.0)",
          ge=0.0,
          le=1.0,
      ),
      normalized_y: float = Field(
          description="Normalized y-coordinate (0.0 to 1.0)",
          ge=0.0,
          le=1.0,
      ),
  ) -> Dict[str, Any]:
      """Calculate absolute screen coordinates from normalized values (0.0-1.0 range)."""
      try:
          screen_size = pyautogui.size()

          absolute_x = int(normalized_x * screen_size.width)
          absolute_y = int(normalized_y * screen_size.height)

          return {
              "status": "success",
              "x": absolute_x,
              "y": absolute_y,
              "screen_width": screen_size.width,
              "screen_height": screen_size.height,
              "message": f"Calculated coordinates: ({absolute_x}, {absolute_y})"
          }
      except Exception as e:
          return {"status": "error", "message": str(e)}

  ---
  2. Update System Prompt Documentation

  Before (absolute coordinates - not scalable):
  | Element | Coordinates | Description |
  |---------|------------|-------------|
  | address_bar | (500, 90) | Browser address bar |
  | search_button | (960, 540) | Center search button |

  After (normalized coordinates - scalable):
  | Element | Normalized Coords | Ref Screen | Description |
  |---------|------------------|------------|-------------|
  | address_bar | (0.260, 0.083) | 1920×1080 | Browser address bar |
  | search_button | (0.500, 0.500) | Any | Center search button |
  | settings_icon | (0.950, 0.050) | 1920×1080 | Top-right settings |

  **Usage Pattern:**
  1. Call `calculate_screen_coordinates(normalized_x, normalized_y)`
  2. Use returned `x` and `y` with PyAutoGUI's `move_mouse(x, y)`

  ---
  3. Agent Workflow

  # Agent execution flow:

  # Step 1: Calculate absolute coordinates
  coords = calculate_screen_coordinates(0.260, 0.083)
  # Returns: {"status": "success", "x": 665, "y": 119, "screen_width": 2560, "screen_height": 1440}

  # Step 2: Move mouse to calculated position
  move_mouse(coords["x"], coords["y"])

  # Step 3: Click
  click_mouse()

  ---
  Alternative: Enhanced Version with Window Support

  For better accuracy, add window-relative calculation:

  def calculate_window_coordinates(
      normalized_x: float = Field(ge=0.0, le=1.0),
      normalized_y: float = Field(ge=0.0, le=1.0),
      use_active_window: bool = Field(
          default=False,
          description="Calculate relative to active window instead of full screen"
      ),
  ) -> Dict[str, Any]:
      """Calculate coordinates relative to screen or active window."""
      try:
          if use_active_window:
              window = pyautogui.getActiveWindow()
              base_x, base_y = window.left, window.top
              width, height = window.width, window.height
          else:
              base_x, base_y = 0, 0
              screen_size = pyautogui.size()
              width, height = screen_size.width, screen_size.height

          absolute_x = base_x + int(normalized_x * width)
          absolute_y = base_y + int(normalized_y * height)

          return {
              "status": "success",
              "x": absolute_x,
              "y": absolute_y,
              "reference": "window" if use_active_window else "screen",
              "width": width,
              "height": height
          }
      except Exception as e:
          return {"status": "error", "message": str(e)}

  How to Calculate Normalized Coordinates

  Convert your existing absolute coordinates:

  # Your reference: 1920×1080 screen
  reference_width = 1920
  reference_height = 1080

  # Existing absolute coordinates
  address_bar = (500, 90)
  search_button = (960, 540)
  settings_icon = (1824, 54)

  # Calculate normalized (do this once, document in prompt)
  address_bar_normalized = (500/1920, 90/1080)     # (0.260, 0.083)
  search_button_normalized = (960/1920, 540/1080)  # (0.500, 0.500)
  settings_icon_normalized = (1824/1920, 54/1080)  # (0.950, 0.050)

  Advantages of This Design

  ✅ Simple: One new tool, minimal code✅ Scalable: Works on any resolution✅ Cost-effective: No image storage needed✅ Maintainable: Update normalized coords in one place (system prompt)✅ Flexible: Can extend to
  window-relative if needed✅ Fast: Simple math calculation, no I/O✅ Deterministic: Same normalized coords → consistent behavior

  Limitations & Considerations

  ⚠️ Browser chrome doesn't scale linearly - Address bar height is often fixed
  - Solution: Test on target resolutions, adjust normalized values if needed
  - Better: Use window-relative mode for browser UI elements

  ⚠️ DPI scaling - High-DPI displays may need adjustment
  - Solution: PyAutoGUI handles this automatically on most platforms

  ⚠️ Multi-monitor - Coordinates assume primary monitor
  - Solution: Document this limitation, or add monitor selection parameter

  Recommended Implementation Steps

  1. Add calculate_screen_coordinates tool to realtimex-computer-use
  2. Add pyautogui dependency to pyproject.toml
  3. Convert existing coordinates to normalized format
  4. Update system prompt with normalized coordinates table
  5. Update agent instructions with usage pattern
  6. Test on different resolutions to validate accuracy

  Should I proceed with implementing calculate_screen_coordinates tool, or would you prefer the enhanced window-relative version?

> Great! I approve your solution for the `calculate_screen_coordinates` tool, since PyAutoGUI is not included in this package. Your next tasks are:
- Write documentation summarizing our discussion, the current issue, and the chosen approach.  
Ensure the document is concise yet descriptive. I’ll then delegate this documentation to update the `realtimex-pyautogui-server` repository and adjust the system prompt accordingly.

Also, save it to a system file for easy tracking. 

⏺ I'll create comprehensive documentation for the coordinate scaling solution.

     # Resolution-Independent Coordinate System Design
     ## Problem Statement
     AI agents require consistent UI element coordinates across different screen resolutions. System prompts currently document element positions using absolute coordinates (e.g., `address_bar: (500, 90)`), which only work
     on specific screen resolutions (e.g., 1920×1080). When customers use different resolutions, these coordinates become invalid, causing automation failures.
     ## Challenges
     **Why simple scaling doesn't work perfectly:**
     - Browser UI elements (chrome, toolbars) have fixed/minimum sizes that don't scale linearly
