GitHub Copilot reading .claude/ configuration directory without explicit consent

When using Claude through a GitHub Copilot subscription in VS Code, the session reads from ~/.claude/ (memory files, project settings, CLAUDE.md) — which is Anthropic's Claude Code configuration directory.

Evidence: Token usage increases in GitHub Copilot settings (github.com/settings/copilot/features) but not in Claude settings (claude.ai/settings/usage), yet the session has full access to .claude/ project memory and configuration.

This raises concerns about:

• Data boundary between competing products sharing a config directory
• Lack of explicit user consent for cross-product config access
• Billing transparency (unclear which subscription is active)

Question: Should there be a safeguard ensuring .claude/ data is only accessible when billed through an Anthropic subscription?
