+# update-context.ps1 — Copilot integration: create/update .github/copilot-instructions.md
+#
+# This is the copilot-specific implementation that produces the GitHub
+# Copilot instructions file. The shared dispatcher reads
+# .specify/integration.json and calls this script.
+#
+# NOTE: This script is not yet active. It will be activated in Stage 7
+# when the shared update-agent-context.ps1 replaces its switch statement
+# with integration.json-based dispatch. The shared script must also be
+# refactored to support SPECKIT_SOURCE_ONLY (guard the Main call) before
+# dot-sourcing will work.
+#
+# Until then, this delegates to the shared script as a subprocess.
