verify

verify is a skill for Claude Code from studioKjm/ai-harness-template. It costs 79 tokens per session (369 once invoked), scanned A, original, MIT.

A local, evidence-based procedure for checking that an implemented feature or bug fix works in the actual app. It uses a browser, test accounts, logs, and screenshots or command output rather than relying only on linting or type checks.

In plain words
What is it for?
Use it after implementation or when asked to check behavior, the UI, or end-to-end (E2E) behavior. It covers starting local services, testing relevant user roles, checking console and server logs, and cleaning up.
Why use it?
It catches problems that static checks cannot, such as broken screens, incorrect permissions, browser errors, or server failures. It also records what was and was not verified before completion is claimed.

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 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 14d 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

로컬 검증 (증거 기반)

완료를 선언하기 전에 증거(명령 출력, 스크린샷)를 확보한다. 타입체크나 lint 통과만으로는 동작 검증이 아니다.

  1. 정적 검사: 변경 파일에 대한 lint와 타입체크 (프로젝트의 CLAUDE.md 명령 참고). 기존 오류(baseline)와 이번 변경의 오류를 구분한다.
  2. 환경: 로컬 DB/서비스가 떠 있는지 확인하고, 앱이 로컬 환경변수를 가리키는지 확인한다. 원격 운영 값으로 앱을 띄우지 않는다.
  3. 서버를 백그라운드로 실행하고 준비될 때까지 기다린다.
  4. 브라우저(claude-in-chrome 등)로 접속해 시드 계정으로 로그인하고, 변경한 기능의 인수 조건을 하나씩 확인한다.
  5. 역할이 여러 개 관련되면 각 역할로 확인하고, 권한이 없는 역할의 접근이 차단되는지도 본다.
  6. 브라우저 콘솔과 서버 로그에 새 오류가 없는지 확인한다.
  7. 서버 프로세스와 열었던 탭을 정리한다.
  8. 결과를 짧게 보고한다. 확인하지 못한 것은 확인하지 못했다고 적는다.

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.
