Clojurians Log v2

Hi folks... question about clj-kondo. in intellij/cursive I have the following source:

(try
    (let []
      42)
    (let [;; Parse JSON string to Java object
          json-obj (JsonUtils/fromString json-str)

-- i've just thrown that redundant let in to hopefully trigger clj-kondo. it's not highlighting, or being raised on "problems" in my IDE. Does cursive use a subset of the clj-kondo rules? What might be happening, please?
