summary

A tool instruments namespaces, records runtime observations, and generates clojure.spec fdefs and aliases automatically; it ships as a Leiningen plugin and a REPL API. Applied to projects like clojure-time and ring-util-codec, it rewrites top-level functions, emits multi-specs and shared map aliases, and even uncovers uncovered paths (11 failing assertions in one run). Limitations include lost keyword-arg/rest arities, over-specific singleton collection specs from sparse tests, and merged arity info when only a few call shapes are observed.
