Clojurians Log v2

I'm asking because I have just that, and I'm unable to tell Kondo how to find my hook:

$ head -n 9 kondo_hooks_for_application_programmers.clj
^{:nextjournal.clerk/visibility {:code :fold :result :hide}}
(ns kondo-hooks-for-application-programmers
  {:nextjournal.clerk/toc true
   :clj-kondo/config
   '{:hooks
     {:analyze-call
      {kondo-hooks-for-application-programmers/defgrinning
       kondo-hooks-for-application-programmers/defgrinning-hook}}}}
  (:require [clojure.string :as str]))

$ ls
deps.edn                                    kondo_hooks_for_application_programmers.clj
index.edn                                   kondo-does-not-understand-it.png
index.html                                  play.edn

$ cat deps.edn
{:paths ["."],
 :deps {clj-kondo/clj-kondo {:mvn/version "2025.09.22"}
        io.github.teodorlu/play.teod.eu {:local/root ".."}}}

$ clj-kondo --lint kondo_hooks_for_application_programmers.clj
WARNING: file kondo_hooks_for_application_programmers not found while loading hook

I missed this part from https://github.com/clj-kondo/clj-kondo/blob/master/doc/hooks.md: > This code will be placed in a file hooks/with_bound.clj in your .clj-kondo directory.

Back to work! 😄

got it working! 😁

$ clj-kondo --lint kondo_hooks_for_application_programmers.clj | grep "Radioactivity disallowed"
kondo_hooks_for_application_programmers.clj:151:1: error: Radioactivity disallowed, it does not cause grinning!

reading the docs helps, spelling my question out helps.
