Thanks for the PR! Before we merge it there are a couple changes we'd need to get the standard tags query up to par with our internal queries:

• Parameter capture (@codeium.parameter), for example: https://github.com/Exafunction/codeium-parse/blob/f30eafb76ba18d1014ec454147aaa8dde7082bb8/queries/javascript_functions.scm#L10
• Function/class body capture (@body), to help us distinguish declarations and definitions. Not super familiar with Ruby but it seems to not have declarations, so we would need @body captures for all class/method/function queries. For example: https://github.com/Exafunction/codeium-parse/blob/f30eafb76ba18d1014ec454147aaa8dde7082bb8/queries/javascript_functions.scm#L11

And then the last thing is a test file so we can generate golden query results: https://github.com/Exafunction/codeium-parse/tree/main/test_files

Happy to answer questions here or on our Discord.

Given #22 has merged, I'll go ahead and close this.
