Hi all,

I want to remove some rules that auto and safe use on proof context.

Is it possible to use declare and remove a given rule from the set of
rules inside auto and safe?

If yes, can someone give me an example on how can we do that (the
options that declare needs) ? example removing a given rule used by
safe!

It would be helpful if someone can link a document
on the command declare.

Best,

Yakoub.

Depends if it is a simp rule or a logic rule:

For logic rules:
declare exI[rule del]

For simp rules use:
declare fun_eq_iff[simp del]
