clojure

Clojure / ClojureScript skills for the cleancoders stack (c3kit, Reagent, Speclj, and cleancoders forms).

Skills

Skill	When to use
/clojure:creating-pages	Creating a new page/route in a ClojureScript SPA
/clojure:writing-migrations	Writing a c3kit bucket/migrator database migration
/clojure:using-forms	Creating or modifying forms that use cleancoders.forms.core
/clojure:writing-tests	Writing Speclj tests (structure, selectors, wire helpers, autorunner recovery)
/clojure:writing-reagent-components	Writing or refactoring Reagent components (with-let, after-render, event handlers)
/clojure:using-c3kit-bucket	Working with c3kit bucket (entity lookups, pushing filters into queries, keeping logic in CLJC)
/clojure:writing-clojure-code	Writing backend Clojure code — formatting (cond->, as->, continuation args, let alignment) and handler idioms (short-circuit with or, extract guard helpers, extract reusable predicates)

Hooks

Event	Hook	Purpose
SessionStart	session-start-toolcheck.sh	In a Clojure project, surfaces a one-shot notice listing any missing tools (cljfmt, jq) with install hints. Skipped in non-Clojure projects.
PostToolUse (Edit / Write / MultiEdit)	cljfmt-postedit.sh	Auto-formats .clj / .cljs / .cljc / .edn / .bb with cljfmt fix. If a file was rewritten, notifies Claude on stderr so it re-Reads before the next Edit. Silent no-op when cljfmt or jq is not installed (the SessionStart notice already warned about it).

Tool dependencies

• cljfmt — needed for the format hook. Install with brew install --cask cljfmt or grab the standalone binary from the releases page. The hook silently no-ops without it.
• jq — needed to parse hook input. Almost always already installed; brew install jq if not.

Installation

With the cleancoders marketplace already added:

/plugin install clojure@cleancoders-agent-plugins

Or via .claude/settings.json:

{
  "enabledPlugins": {
    "clojure@cleancoders-agent-plugins": true
  }
}
