sub-kopring-engineer

sub-kopring-engineer is a skill for Claude Code from brody-0125/my-claude-skills. It costs 108 tokens per session (7,810 once invoked), scanned A, original, MIT.

A workflow assistant for Kotlin and Java Spring Boot codebases. It follows a sequence of brainstorming, planning, implementation, and verification while using the project's existing patterns; Hexagonal Architecture separates business rules from outside systems.

In plain words
What is it for?
Use it to plan and implement Spring Boot features, learn project conventions, detect static-analysis tools such as linters, and verify changes.
Why use it?
It reduces repeated instructions and helps new code match the project's language, structure, naming, database, and testing conventions.

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

sub-kopring-engineer 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 12d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/_common.sh, scripts/capture-task-patterns.sh, scripts/discover-project.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Sub Kopring Engineer — Kotlin/Java Spring Boot Workflow Agent

An agent that generates consistent, convention-compliant code through the Brainstorm → Plan → Implement → Verify workflow

Role

A workflow agent that writes code following Hexagonal Architecture (Ports & Adapters) in Kotlin/Java Spring Boot projects. It automatically detects the project language (Kotlin/Java/Mixed) and produces consistent code based on injected context documents without requiring repeated prompting.

Core Principles

  1. Lazy-load context documents per Phase to ensure convention compliance
  2. Sequential execution of Brainstorm → Plan → Implement → Verify
  3. Repeat Verify loop the number of times specified by the user (Ralph-style)
  4. Automatically adjust verification level based on change scale (Tiered Verification)

Quick Start (Zero-Config)

Phase 0 자동으로 모든 설정을 완료하므로 사용자 개입이 필요 없다:

1. Project Discovery    — build.gradle.kts 분석 → 언어, 모듈, 플러그인, 아키텍처 자동 감지
2. Pattern Learning     — Base Class, Annotation, Naming 패턴 자동 학습 후 캐시
3. Static Analysis      — 빌드 플러그인에서 detekt/checkstyle/spotless 등 자동 감지 → .sub-kopring-engineer/static-analysis-tools.txt 생성
4. Hooks Installation   — lint-on-edit, secret-guard, test-quality-gate 자동 설치 (.claude/settings.json)

첫 실행 시 추가 프롬프트 없이 위 4단계가 순차적으로 실행된다. 감지된 설정을 변경하려면 해당 파일을 직접 편집하면 된다:

  • 정적 분석 도구: .sub-kopring-engineer/static-analysis-tools.txt (줄 단위, 삭제 시 재감지)
  • Hooks: .claude/settings.jsonhooks 섹션 (삭제 시 재설치)
