Jo Clojure

jo-clojure - Polyglot Skill Coordinator

Overview

jo-clojure coordinates polyglot skill ecosystems using Clojure as the orchestration layer. It bridges JVM-based skills (Clojure, Babashka, Joker), provides skill composition abstractions, and manages cross-language capability routing.

Role: ERGODIC coordinator in triadic consensus - balances validation (joker) and generation (hy-regime) in skill pipelines.

Quick Start

Set Up Clojure Tooling

# Check Clojure CLI installation
clojure -version

# Create/update project structure
cd /Users/bob/i/boxxy
clojure -X:deps tree

# List available aliases
clojure -X:deps list-aliases

Key Commands

# Start Clojure REPL
clojure

# Run a script
clojure -X user/my-function :arg1 value1

# Evaluate expression
clojure -e '(+ 1 2 3)'

# Run tests
clojure -X:test

Installation

1. Install Clojure CLI (if not already)

# macOS with Homebrew
brew install clojure/tools/clojure

# Or download from https://clojure.org/guides/install_clojure

2. Configure ~/.clojure/deps.edn

The global deps.edn file coordinates all Clojure projects:

{
  :aliases {
    ;; Polyglot skill ecosystem
    :skill-validate  {:extra-deps {org.clojure/clojure {:mvn/version "1.11.1"}
                                    clojure.spec.alpha {:mvn/version "0.2.207"}}}
    :skill-test      {:extra-deps {org.clojure/clojure {:mvn/version "1.11.1"}
                                    expectations/clojure-test {:mvn/version "1.2.1"}}}
    :skill-repl      {:extra-deps {org.clojure/clojure {:mvn/version "1.11.1"}
                                    nrepl/nrepl {:mvn/version "0.9.1"}
                                    cider/cider-nrepl {:mvn/version "0.28.4"}}}

    ;; Polyglot tools
    :bb              {:extra-deps {org.babashka/babashka {:mvn/version "1.3.192"}}}
    :joker           {:extra-deps {candelbp/joker {:mvn/version "0.15.7"}}}

    ;; Color generation (Gay.jl integration)
    :color-gen       {:extra-deps {org.clojure/clojure {:mvn/version "1.11.1"}}}

    ;; GF(3) skill validation
    :gf3-validate    {:extra-deps {org.clojure/clojure {:mvn/version "1.11.1"}
                                    org.clojure/math.numeric-tower {:mvn/version "0.0.4"}}}
  }
}

Polyglot Skill Composition

Pattern 1: Validator → Coordinator → Generator

(defn triadic-skill-pipeline
  "Compose three skills in GF(3) consensus."
  [{:keys [validator coordinator generator]}]
  (let [v-result (validator/run)
        c-state (coordinator/process v-result)
        g-output (generator/produce c-state)]
    {:validation v-result
     :coordination c-state
     :generation g-output
     :gf3-sum (+ (validator/trit)
                 (coordinator/trit)
                 (generator/trit))}))

Pattern 2: Skill to Color Mapping

Uses Gay.jl deterministic color generation:

(defn skill->color
  "Map skill name deterministically to color via splitmix RNG."
  [skill-name seed]
  (let [gen (SplitMixTernary. seed)
        idx (hash skill-name)]
    (gen/color-at idx)))

Pattern 3: Cross-Language Dispatch

Routes to Clojure, Babashka, or compiled binaries:

(defmulti invoke-skill (fn [{:keys [language]}] language))

(defmethod invoke-skill :clojure [spec]
  (require (symbol (:module spec)))
  (apply (resolve (symbol (:function spec))) (:args spec)))

(defmethod invoke-skill :babashka [spec]
  (shell/sh "bb" "-e" (:code spec)))

(defmethod invoke-skill :go [spec]
  (shell/sh (:binary spec) (concat (:flags spec))))

Skill Registry Operations

Reading Skill Metadata

(defn read-skill-properties [skill-dir]
  "Extract SKILL.md frontmatter as Clojure map."
  (let [skill-md (slurp (str skill-dir "/SKILL.md"))
        [_ frontmatter _] (string/split skill-md #"---\n?" 3)
        yaml (yaml/parse frontmatter)]
    yaml))

(defn list-all-skills [skills-root]
  "Enumerate all skills with metadata."
  (->> (io/file skills-root)
       .listFiles
       (filter #(.isDirectory %))
       (map read-skill-properties)))

Validating GF(3) Balance

(defn validate-gf3-triad [skills-map]
  "Check that three skills sum to 0 mod 3."
  (let [trit-sum (->> skills-map
                      vals
                      (map #(get % :gf3-trit 0))
                      (apply +))]
    (= (mod trit-sum 3) 0)))

(defn suggest-balancer [two-skills]
  "Given two skills, find trit needed for third."
  (let [current-sum (apply + (map #(get % :gf3-trit 0) two-skills))
        needed (- (mod (- current-sum) 3))]
    needed))

REPL Startup

Create ~/.clojure/repl-init.clj:

; Load commonly used skills
(require '[clojure.java.io :as io])
(require '[clojure.string :as str])
(require '[clojure.pprint :as pp])

(defn skills-dir []
  "/Users/bob/i/boxxy/skills")

(defn load-skill [name]
  (println (format "Loading skill: %s" name)))

(println "Boxxy skill coordinator ready")
(println "  skills-dir    - show skills directory")
(println "  load-skill    - load a skill by name")

When to Use

• Coordinating multi-language skills: Compose Go, Clojure, Hy, and Zig tools
• GF(3) validation: Check that skill triads maintain conservation
• Skill discovery: List and inspect available skills
• Dynamic dispatch: Route to different implementations based on input
• JVM ecosystem integration: Manage Clojure, Babashka, and other JVM tools
• REPL-based development: Interactive skill testing and composition

When NOT to Use

• Simple single-language tasks (use language-specific skills directly)
• Performance-critical code (use native Go/Zig skills)
• Tasks not requiring triadic balance (simpler coordination systems exist)

GF(3) Conservation

jo-clojure is assigned trit = 0 (ERGODIC) for coordinator role:

Validator (-1) + Coordinator (0) + Generator (+1) ≡ 0 (mod 3)
 [joker]        [jo-clojure]      [hy-regime]

Ensures every triadic composition maintains GF(3) sum ≡ 0 (mod 3).

Common Tasks

Load All Skills and Check Balance

(let [skills (skills/list-all-skills "/Users/bob/i/boxxy/skills")
      trits (map :gf3-trit skills)]
  (println "Total trits:" (apply + trits))
  (println "Balanced?" (zero? (mod (apply + trits) 3))))

Compose Three Skills

(let [validator (skills/find "joker-sims-parser")
      coordinator (skills/find "jo-clojure")
      generator (skills/find "hy-regime")]
  (triadic/validate-triad [validator coordinator generator])
  (triadic/execute [validator coordinator generator] input-data))

Dynamic Skill Invocation

(invoke-skill {:language :go
               :binary "/Users/bob/i/boxxy/bin/joker"
               :flags ["parse" "save.sims3pack"]})

Troubleshooting

"command not found: clojure"

• Install Clojure CLI: brew install clojure/tools/clojure
• Verify: clojure -version

Dependency resolution errors

• Clear cache: rm -rf ~/.m2/repository
• Update indices: clojure -X:deps list-aliases

REPL not starting

• Check Java version: java -version (requires 11+)
• Verify Clojure: clojure -e '(clojure-version)'

GF(3) validation failures

• Check trit assignments in skill metadata
• Verify sum: (+ -1 0 1) should equal 0
