devkit.java.refactor-class

devkit.java.refactor-class is a command for Claude Code from giuseppe-trisciuoglio/developer-kit. It costs 26 tokens per session (2,236 once invoked), scanned A, original, MIT.

A command for refactoring complex Java classes using Clean Architecture, domain-driven design, and Spring Boot patterns. It examines the class and its project context before proposing changes.

In plain words
What is it for?
Use it to improve class structure, separate responsibilities, address design problems, and apply clearer Spring Boot or domain-model patterns.
Why use it?
It helps break down large or difficult classes while considering existing dependencies, tests, Git state, and the surrounding architecture.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devkit.java.refactor-class scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Java Class Refactoring Assistant

Overview

Intelligently refactor complex Java classes following Clean Architecture, DDD patterns, and Spring Boot best practices.

Provides intelligent refactoring for complex Java classes with architectural analysis and Spring Boot patterns. Use when refactoring large or complex Java classes.

Usage

/devkit.java.refactor-class $ARGUMENTS

Arguments

Argument Description
$ARGUMENTS Combined arguments passed to the command

Current Context

  • Current Git Branch: !git branch --show-current
  • Git Status: !git status --porcelain
  • Recent Commits: !git log --oneline -5
  • Test Coverage: !find . -name "*Test.java" -type f | wc -l test files found

Execution Instructions

Agent Selection: To execute this task, use the following agent with fallback:

  • Primary: developer-kit-java:java-refactor-expert
  • If not available: Use developer-kit-java:java-refactor-expert or fallback to general-purpose agent with spring-boot-crud-patterns skill

Refactoring Configuration

Analyzing: $ARGUMENTS

Parameters:

  • $1 - Class file path (required): Path to Java class to refactor
  • $2 - Refactoring scope (optional):
    • cleanup - Code cleanup and style improvements (default)
    • architecture - Architectural pattern improvements
    • performance - Performance optimizations
    • security - Security enhancements
    • testing - Testability improvements
    • comprehensive - All improvements (full refactor)
  • $3 - Options (optional): dry-run, backup, validate-only

Pre-Refactoring Analysis

1. Class Identification and Context

IF "$1" is empty OR not provided THEN Analyze the most complex class in the codebase automatically ELSE Analyze specific class: $1 ENDIF

2. Architecture Pattern Detection

Expected Clean Architecture Structure:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
