The assertion expect(templateContent.length).toBe(templateContent.length) is trivial. Consider using a more meaningful check like toBeGreaterThan(0) to verify the file isn’t empty.

Suggested change
expect(templateContent.length).toBe(templateContent.length); // Just verify it has content
expect(templateContent.length).toBeGreaterThan(0);

The template file path is hardcoded as an absolute path ('C:\Users\orphe\Downloads\playwright-mcp.yaml'). Consider using a relative path or a configuration variable to enhance portability.

Suggested change
const templatePath = 'C:\\Users\\orphe\\Downloads\\playwright-mcp.yaml';
const templatePath = path.join(__dirname, 'playwright-mcp.yaml');

Hey @robertheadley, the additions to the marketplace are handled directly by the dev team. We just need to wait for them to add the requested MCPs on their end.

Really appreciate you taking the initiative to contribute. Thank you!
