+name: Copilot Setup Steps
+
+# This workflow sets up the development environment for GitHub Copilot coding agent
+# It uses a pre-built container image with all the necessary tools already installed
+#
+# The workflow:
+# - Uses the heaths/azure-sdk-for-rust:latest container image with all dependencies
+# - Maps the repository into the standard devcontainer workspace location
+# - Caches Cargo dependencies for improved performance
+# - Runs comprehensive workspace verification (check, clippy, fmt)
+# - Tests basic functionality to ensure the environment is ready
+#
+# This approach leverages a pre-built image that contains all the tools from
+# the devcontainer configuration, avoiding the need to install tools at runtime
+#
+# Triggers:
+# - Manual execution via workflow_dispatch 
+# - Weekly scheduled runs to keep environment fresh
+# - Automatic runs when key configuration files change
+
