The sed command provided uses the macOS syntax (sed -i ''), which will not work on Linux systems. On Linux, the command should be sed -i (without the empty string). Consider providing both versions or using a more portable approach like sed -e 's/{MY_ORGANIZATION}/YOUR-ORG-SLUG/g' file > file.tmp && mv file.tmp file in a loop, or clarify that the command shown is macOS-only and provide the Linux alternative.

Suggested change

	# macOS/Linux
	find agents -name "*.md" -type f -exec sed -i '' 's/{MY_ORGANIZATION}/YOUR-ORG-SLUG/g' {} +
	# macOS (BSD sed)
	find agents -name "*.md" -type f -exec sed -i '' 's/{MY_ORGANIZATION}/YOUR-ORG-SLUG/g' {} +
	# Linux (GNU sed)
	find agents -name "*.md" -type f -exec sed -i 's/{MY_ORGANIZATION}/YOUR-ORG-SLUG/g' {} +

The SUPPORT.md file states "For help or questions about using this project, please file an issue" but the issue template configuration (.github/ISSUE_TEMPLATE/config.yml) disables blank issues and redirects general questions to GitHub Discussions. This creates inconsistent guidance for users. The SUPPORT.md should be updated to direct users to GitHub Discussions for questions, consistent with the issue template configuration.

The link text "github.com/copilot/agents discussions" is misleading because it suggests it links to github.com/copilot/agents, but the actual URL is to github.com/github/actions-migrations-via-copilot/discussions. The link text should be updated to clearly indicate it links to this project's discussions, not the Copilot agents interface.

The LICENSE file is missing a copyright year. Standard practice for MIT licenses is to include the year or year range (e.g., "Copyright (c) 2024 GitHub, Inc." or "Copyright (c) 2024-present GitHub, Inc."). This helps establish when the copyright was first claimed and is important for legal clarity.
