## What it is
clj-kondo is a static analyzer and linter for Clojure, ClojureScript, and EDN code that detects errors and style issues without executing the program. It ships as a fast GraalVM native binary and integrates with editors and CI pipelines.

## Use cases
- lint clojure code for arity errors and unused vars
- catch mistakes in clojure code while typing in the editor
- check clojurescript and edn files for unresolved symbols
- enforce clojure style guide rules in CI
- find redundant do and let wrappers and unused imports
- type check clojure code statically

## When to choose
- you write Clojure or ClojureScript and want fast, accurate linting
- you need static analysis of Clojure code in CI or an editor
- you want a fast native binary with no JVM startup cost

## When to avoid
- you need linting for languages other than Clojure/ClojureScript/EDN
- you want runtime or dynamic analysis rather than static checks

- domain: developer-tools, programming-languages, parsers, testing
