# Are Defaults for Code Golf implicit?

Recently, I've made some major edits to a couple of challenges, and I sort of instinctively cited the appropriate defaults here on meta, like:

Write a program or function to output the sum of unicorns less than an input n.

Need I do this every single time? We've established that authors don't need to mention that standard loopholes are disallowed by default, because... they're disallowed by default, and answers that violate them are deleted, and this is a given.

Assuming a given challenge will use the stated defaults as usual, should authors always have to cite them like this, using the magic words and magic links, or can I just say something that implies this challenge uses the defaults?

Yes, the defaults apply... by default.

From the code-golf tag wiki:

If 1. and 7. are not specified, the following defaults are used:

Mentioning them in the challenge doesn't hurt, but it isn't required.

• I agree. We still have an influx of new users, who have not always seen the wikis or related information before choosing to participate. I think it would be helpful to include the relevant links and references every so often, making it more likely that new users will come upon the information before making a mistake. – mbomb007 Apr 22 '16 at 18:18
