Learn English – the meaning of the phrase “the ‘one ring’ of something”

phrase-meaning

I have encountered the phrase in the following context

This tool is the 'one ring' of static analysis tools in Python

Best Answer

Tolkien: Lord of the Rings:

Three Rings for the Elven-kings under the sky,

Seven for the Dwarf-lords in their halls of stone,

Nine for Mortal Men doomed to die,

One for the Dark Lord on his dark throne.

One Ring to rule them all. One Ring to find them,

One Ring to bring them all and in the darkness bind them.

To be true to Tolkien the 'one ring' should have the power to control the lesser rings, I doubt that will be true of this Static Analysis Tool. More likely the author simply means most powerful or most desirable, precious.
