mcp-server-uiautomation: Instructions file for GitHub Copilot

.github/copilot-instructions.md

mcp-server-uiautomation copilot-instructions.md is an instructions file for GitHub Copilot from trsdn/mcp-server-uiautomation. It costs 349 tokens per session, scanned A, original, MIT.

Coding instructions for a Windows-only toolkit that inspects and automates desktop applications through Windows UI Automation. They explain the project structure, rules, and checks to run before finishing changes.

In plain words
What is it for?
Use them when changing the toolkit, its command-line program, its MCP server, or its VS Code extension. They point to the key documents and provide build, smoke-test, and desktop-check commands.
Why use it?
They give an agent the project context and help prevent outdated names, mismatched command-line and server behavior, unsafe Windows integration, and untested changes.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is trsdn/mcp-server-uiautomation's own configuration. It tells GitHub Copilot how to work on mcp-server-uiautomation itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server-uiautomation configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-server-uiautomation copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

GitHub Copilot Instructions - UIAutomationMcp

Project focus

UIAutomationMcp is a Windows-only automation toolkit for inspecting live desktop UI with Windows UI Automation.

The active product surfaces are:

  • src\UIAutomationMcp.CLI (uiamcp)
  • src\UIAutomationMcp.McpServer
  • vscode-extension

Read first

When changing code, start with:

  • docs\UIAUTOMATION-COM-REFERENCE.md
  • README.md
  • FEATURES.md

Core rules

  • Do not reintroduce legacy pre-migration naming.
  • Keep CLI and MCP behavior aligned when you add or change UIA operations.
  • UI Automation access must remain safe for Windows COM/STA execution.
  • Prefer focused docs and examples that match the current UIA-only repo.
  • Validate changes with the smallest relevant build or smoke command before finishing.

Quick validation

dotnet build UIAutomationMcp.sln

dotnet run --project src\UIAutomationMcp.Smoke\UIAutomationMcp.Smoke.csproj

dotnet run --project src\UIAutomationMcp.CLI\UIAutomationMcp.CLI.csproj -- desktop

Current architecture

  • UIAutomationMcp.ComInterop - typed bootstrap and UI Automation COM access
  • UIAutomationMcp.Service - shared query surface used by all entry points
  • UIAutomationMcp.CLI - JSON-friendly terminal entry point
  • UIAutomationMcp.McpServer - MCP tool host for assistants
  • vscode-extension - packaged VS Code surface bundling the CLI and MCP server
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
