spec-verify

spec-verify is a skill for Claude Code from jh941213/codex-lattice. It costs 57 tokens per session (723 once invoked), scanned A, original, MIT.

A checker that compares a software implementation with the requirements written in a SPEC.md file. It reviews functional and non-functional requirements, interface details, APIs, and security points when applicable.

In plain words
What is it for?
Use it after implementing a feature to review the code against its specification and record missing items, improvement suggestions, and verification results.
Why use it?
It helps reveal which agreed requirements are missing or incomplete before work is considered finished. It also produces specific feedback for follow-up changes.

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

spec-verify 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 6d 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.

What it actually says

SPEC 검증

명세서 기반 작업 완료 후 검증하는 스킬입니다.

트리거

  • "스펙 검증", "spec-verify", "명세서 검증", "구현 검증"

워크플로우

1단계: 검증 경로 선택

기본은 현재 세션에서 읽기 전용으로 검증한다. 사용자가 서브에이전트 사용을 명시했거나 현재 Codex 지침상 허용되면 explorer 또는 qa 역할로 분리한다.

검증 프롬프트:
  SPEC.md 파일을 읽고 다음을 검증하세요:

  1. 명세서의 모든 요구사항이 구현되었는지 확인
  2. 각 항목별 체크:
     - [ ] 기능적 요구사항
     - [ ] 비기능적 요구사항
     - [ ] UI/UX 명세
     - [ ] API 설계 (해당 시)
     - [ ] 보안 고려사항

  3. 누락된 항목이 있으면 구체적으로 명시
  4. 개선 제안 사항 포함

  결과를 SPEC-REVIEW.md 파일로 작성하거나 사용자에게 요약하세요.

2단계: 피드백 반영

검증 결과에 누락 사항이 있으면:

  1. SPEC-REVIEW.md 내용을 사용자에게 보여줌
  2. 수정 여부 확인 (AskUserQuestion 사용)
  3. 승인 시 누락 사항 구현

3단계: 완료 보고

모든 항목이 완료되면:

## 검증 완료

### 구현 상태
- [x] 기능적 요구사항: 100%
- [x] 비기능적 요구사항: 100%
- [x] UI/UX: 100%
- [x] 테스트: 100%

### 주의사항
- ...

### 다음 단계 제안

검증 체크리스트

## SPEC 검증 체크리스트

### 기능 완성도
- [ ] 모든 기능적 요구사항 구현됨
- [ ] 모든 엣지 케이스 처리됨
- [ ] 에러 핸들링 적절함

### 코드 품질
- [ ] 타입 안전성 확보
- [ ] 린트 규칙 준수
- [ ] 테스트 커버리지 충분

### 문서화
- [ ] 코드 주석 적절
- [ ] API 문서 (해당 시)
- [ ] README 업데이트

### 보안
- [ ] 입력 검증
- [ ] 인증/권한 확인
- [ ] 민감 정보 보호

핵심 원칙

  1. 객관적 검증: 명세서 대비 실제 구현 비교
  2. 구체적 피드백: "안 됨" 대신 "X 기능의 Y 부분 누락"
  3. 반복 가능: 피드백 → 수정 → 재검증 사이클

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.

spec-verify is a skill published in the GitHub repository jh941213/codex-lattice (19 stars, last pushed 3mo ago), licensed MIT. It adds 57 tokens to every session and 723 once invoked, about $0.0003 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 2026-08-30.
