Cursor IDE requires YAML frontmatter with `alwaysApply: true` in .mdc rule files for them to be automatically loaded. Without this frontmatter, users must manually configure glob patterns for the rules to take effect. This fix adds frontmatter generation to both the bash and PowerShell update-agent-context scripts, handling three scenarios: - New .mdc file creation (frontmatter prepended after template processing) - Existing .mdc file update without frontmatter (frontmatter added) - Existing .mdc file with frontmatter (no duplication) Closes github#669 🤖 Generated with [Claude Code](https://claude.com/code) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
