verify-implementation

verify-implementation is a skill for Claude Code, Codex from sangrokjung/claude-forge. It costs 37 tokens per session (2,797 once invoked), scanned A, original, MIT.

A workflow that runs a project’s verification skills to produce a report on coding patterns, architecture rules, and project conventions. It is intended for work after implementation, before a pull request, or during code review.

In plain words
What is it for?
Use it to audit new features, review pull-request readiness, check architecture and coding conventions, or run selected verification categories.
Why use it?
It finds rule and pattern violations that ordinary build, type, lint, and test checks may not detect. Issues can be reported by severity and optionally fixed automatically.

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

verify-implementation 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 yesterday.

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.

구현 검증

목적

프로젝트에 등록된 모든 verify-* 스킬을 실행하여 통합 패턴 검증을 수행합니다:

  • 각 스킬의 Workflow에 정의된 검사를 실행
  • 각 스킬의 Exceptions를 참조하여 false positive 방지
  • 발견된 이슈에 severity 레벨 분류
  • 사용자 승인 후 수정 적용 및 재검증

verification-engine과의 역할 구분

항목 verification-engine verify-implementation (이 스킬)
대상 기술 검증 (빌드, 타입, 린트, 테스트) 패턴 검증 (코딩 규칙, 아키텍처 패턴, 프로젝트 규약)
트리거 /handoff-verify /verify-implementation
자동 수정 Fixable 9종 즉시 수정 사용자 승인 후 수정 (기본) 또는 --fix로 자동

두 시스템은 상호보완입니다. 기술 검증은 verification-engine에, 패턴 검증은 이 스킬에 위임합니다.

실행 시점

  • 새로운 기능을 구현한 후
  • Pull Request를 생성하기 전
  • 코드 리뷰 중
  • 코드베이스 규칙 준수 여부를 감사할 때
  • /handoff-verify 통과 후 패턴 준수 추가 확인 시

실행 플래그

플래그 설명 기본값
--fix 발견 이슈 자동 수정 (사용자 확인 없이) OFF
--report-only 보고서만 생성, 수정 제안 없음 OFF
--severity <level> 특정 심각도 이상만 보고 (CRITICAL/HIGH/MEDIUM/LOW) LOW (전체)
--category <name> 특정 verify-* 스킬만 실행 (예: --category api) 전체

심각도 레벨

레벨 설명 예시
CRITICAL 즉시 수정 필수. 배포 차단 인증 없는 API 엔드포인트, 하드코딩된 시크릿
HIGH PR 전 수정 권장 패턴 위반, 누락된 유효성 검사
MEDIUM 수정 권장하나 긴급하지 않음 네이밍 규칙 불일치, 불필요한 코드
LOW 개선 제안 더 나은 패턴 존재, 문서 보강 필요

실행 대상 스킬

이 스킬이 실행하는 검증 스킬 목록입니다. /manage-skills가 스킬을 생성/삭제할 때 이 목록을 자동 업데이트합니다.

# 스킬 설명
(프로젝트에서 /manage-skills로 생성됨) (프로젝트별 verify-* 스킬은 각 프로젝트에서 동적으로 생성됩니다) (프로젝트 지침을 참조하세요)

워크플로우

Step 1: 소개 및 실행 전략 결정

위의 실행 대상 스킬 섹션에 나열된 스킬을 확인합니다.

선택적 인수가 제공된 경우:

  • 특정 스킬 이름 -> 해당 스킬만 필터링
  • --category <name> -> verify-<name>* 패턴과 매칭되는 스킬만 필터링
  • --severity <level> -> 모든 스킬 실행 후 해당 심각도 이상만 보고

등록된 스킬이 0개인 경우:

## 구현 검증

검증 스킬이 없습니다. `/manage-skills`를 실행하여 프로젝트에 맞는 검증 스킬을 생성하세요.

이 경우 워크플로우를 종료합니다.

등록된 스킬이 1개 이상인 경우:

적응형 실행 전략 결정
IF 실행 대상 스킬 수 <= 5:
    -> 순차 실행 (토큰 절약, 컨텍스트 내 직접 실행)
ELSE IF 실행 대상 스킬 수 >= 6:
    -> 병렬 실행 (Task 서브에이전트, fresh context)

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.

verify-implementation is a skill published in the GitHub repository sangrokjung/claude-forge (825 stars, last pushed 2d ago), licensed MIT. It adds 37 tokens to every session and 2,797 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
