How do I handle complex multiline Clojure code?

For complex or multiline expressions, using the heredoc (EOF) syntax is strongly recommended to ensure correct parsing and execution.

Does it support state between different commands?

Yes, nREPL sessions are persistent. Variables defined or namespaces required in one evaluation remain available in subsequent calls until the server restarts.

Can I use this with shadow-cljs or Babashka?

Yes, this skill is compatible with any nREPL-compliant server, including standard Clojure JVM, Babashka, and shadow-cljs environments.

How does the skill find my nREPL port?

The skill uses the --discover-ports flag to scan the current directory for .nrepl-port files or active servers like Babashka and shadow-cljs.

API開発

Evaluates Clojure code via nREPL to verify compilation, test function behavior, and manage interactive development sessions.

This skill integrates Clojure's interactive REPL workflow directly into Claude Code, allowing developers to execute code against running nREPL servers including Babashka and shadow-cljs. It enables real-time verification of code changes through namespace reloading, persistent session management, and automatic port discovery. Whether you need to debug a specific function, check file compilation, or inspect the state of a live application, this skill provides a seamless bridge between the AI and your Clojure runtime environment for faster, REPL-driven development.
