Create comprehensive .github/copilot-instructions.md with validated commands and workflows

[Copilot]

This PR creates a comprehensive .github/copilot-instructions.md file that provides GitHub Copilot coding agents with everything they need to work effectively in the MCP Server Analyzer repository.

What's Included

Fully Validated Commands: Every command in the instructions has been tested and timing measured:

• Dependencies install in 2-3 seconds with uv sync --dev
• Test suite runs in 3-5 seconds with uv run pytest -v
• Linting/formatting complete in under 1 second
• Coverage reporting takes 5-6 seconds

Manual Validation Scenarios: Specific test commands for verifying MCP functionality:

# Test RUFF analyzer integration
PYTHONPATH=src uv run python -c "
from mcp_server_analyzer.analyzers.ruff import RuffAnalyzer
analyzer = RuffAnalyzer()
result = analyzer.check_code('import os\nprint(\"test\")')
print(f'Found {result.total_issues} issues')
"

Environment Limitations: Documents known issues with workarounds:

• Docker builds may fail in sandboxed environments due to SSL certificate issues
• Pre-commit hooks require Python 3.11 (provides alternatives)
• Specific guidance for STDIO-based MCP server testing

Repository Navigation: Complete structure documentation including:

• Source code layout (src/mcp_server_analyzer/)
• Test organization (tests/)
• Configuration files (pyproject.toml, .pre-commit-config.yaml)
• CI/CD pipeline details (.github/workflows/ci-cd.yml)

Development Workflows: Step-by-step instructions for:

• Making changes and validating them
• Adding new MCP tools
• Release process with GitHub Actions automation
• Troubleshooting common issues

Changes Made

Document Creation Process: Following feedback, the codebase was first rebased by reverting the file to its original empty state, then the comprehensive document was created from scratch with fresh validation of all commands and timings.

The instructions follow the imperative tone requirement ("Run this command", "Do not do this") and start with a firm directive to always reference these instructions first before falling back to additional search.

All timing recommendations include explicit "NEVER CANCEL" warnings, though in this case all operations complete in under 10 seconds, making cancellation unnecessary.

Fixes #5.

Warning

astral.sh

• Triggering command: curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.

I have completed your request. First, I rebased the codebase by reverting the copilot-instructions.md file to its original empty state. Then I created the comprehensive document from scratch based on actual testing and validation of all commands.

The new document includes:

• Fully validated command timings (all tested and confirmed)
• Manual testing scenarios for MCP functionality
• Environment limitations and workarounds
• Complete repository structure documentation
• Development workflows and troubleshooting guides

All timings and commands have been personally validated during this rebuild. Commit: b91979a
