Based on your context I located the following book (google books search): <I>Evidencia, argumentación y persuasión en la formulación de políticas</I> escrito por Giandomenico Majone. Although the whole book cannot be seen, the index under H shows this:
herramientas: del análisis de políticas, 100-101; trampas en la elección de, 100-102; y el “nuevo herramentismo”, 101. Véase también políticas, instrumentos de

Well turns out that this book was originally written in English (you can see this on the very first page of the Spanish version)
Primera edición en inglés, 1989
Primera edición en español, 1997

<I>Evidence, Argument, and Persuasion in the Policy Process</I> by Giandomenico Majone which I found on Amazon. Once again you cannot see the whole book but you can see a preview which includes the index, in the English version you find the following under T:

Tools: of policy analysis, 61; pitfalls in the choice of, 61-63; and "new toolism", 62; see also Policy Instruments
https://www.amazon.com/Evidence-Argument-Persuasion-Policy-P...

You way find some references to "toolism" on line that say the term was coined in 2013 by German economist Egmont Kakarot-Handtk but Mr. Majone was already using it in 1989, perhaps with a slight different meaning.

Hope this helps!

Here is in use:
In disciplines with a long intellectual tradition the introduction of new tools usually opens up lines of research that were previously inaccessible. In newer fields of inquiry, on the other hand, we often witness the phenomenon of "new toolism", a disease to which policy analysts seem to be particularly predisposed. Those affected by this disease "come possessed of and by new tools (various forms of mathematical programming, vast air-battle simulation machine models, queuing models, and the like), and they look earnestly for a problem to which one of these tools might conceivable apply"
