The LORD possessed me in the beginning of his way, before his works of old.
(Proverbs 8:22 KJV)
יְֽהוָה קָנָנִי רֵאשִׁית דַּרְכֹּו קֶדֶם מִפְעָלָיו מֵאָֽז
It is common to understand "works of old" to refer to creation and then the verse speaks to "wisdom" being an integral part of creation. "Works" is מִפְעָל, which is only used in two other places:
Come, behold the works of the LORD, what desolations he hath made in the earth.
Come and see the works of God: he is terrible in his doing toward the children of men.
Obviously these are works God does after creation done specifically to get man's attention:
- Believers to place confidence in the LORD (Psalm 46)
- Invite all people to consider God's works in the Exodus (Psalm 66)
Given the other uses, it seems to mean works of salvation, not works of creation.
