fe-review is a skill for Claude Code from sh5623/fe-rail. It costs 46 tokens per session (896 once invoked), scanned A, original, MIT.

A review process for completed frontend code, which is code that runs in a web browser or builds user interfaces. It checks types, performance, accessibility, and general code quality.

In plain words
What is it for?
Use it after frontend work to review the code, run tests, and request focused follow-up checks for accessibility or performance issues.
Why use it?
It gives a final quality check before committing code or opening a pull request, helping find problems that may be missed during implementation.

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

fe-review 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 5d 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

FE Review 스킬

구현된 코드를 타입·성능·a11y·품질 4개 축으로 병렬 검토합니다.

When to Use

  • 구현 완료 직후
  • 커밋 전 마지막 품질 게이트
  • PR 생성 전

Instructions

Phase 1 — 에이전트 위임

리뷰는 직접 수행하지 않고 전담 에이전트에 위임한다:

에이전트 역할 위임 조건
fe-reviewer 타입·성능·a11y·품질 4축 기본 리뷰 항상
fe-a11y-auditor WCAG AA 정밀 감사 fe-reviewer에서 접근성(a11y) BLOCK/WARN 발생 시
fe-perf-auditor 번들·Image·Font·Tailwind purge 정밀 감사 (Next.js / Vite SPA 공통) fe-reviewer에서 성능 BLOCK/WARN 발생 시
fe-test-runner 테스트 실행·실패 분류 항상 (스택트레이스는 에이전트 내부에서 처리)
fe-refactor-advisor 리팩토링 방향 분석 명시적 요청 시

모든 에이전트는 READ-ONLY — 메인 세션이 결과를 받아 수정 여부를 결정한다.

Phase 2 — 리뷰 결과 보고 (합산 판정)

fe-reviewer 의 출력을 본문으로 전달하되, "커밋 준비 완료" 판정은 메인이 합산해서 내린다 — reviewer BLOCK 0 그리고 fe-test-runner exit 0 그리고 추가 감사(a11y·perf) BLOCK 0 일 때만. 테스트가 실패했는데 reviewer BLOCK 이 0 이라고 "준비 완료" 로 적지 않는다. 요약 줄에 각 소스의 결과를 나란히 적는다: 리뷰 BLOCK 0 · 테스트 exit 0 (42/42) · a11y BLOCK 0 → 커밋 준비 완료 / 리뷰 BLOCK 0 · 테스트 exit 1 (2 실패) → 수정 후 재검토. 위임 컨텍스트에는 변경 파일 목록(신규 파일 포함) 을 넘긴다 — 에이전트는 tracked diff ∪ untracked 와 교차 확인한다. 그리고 docs/framework-rules.md 의 절대경로(이 스킬이 로드될 때 주어진 base directory 기준 ../../docs/framework-rules.md)를 함께 넘긴다 — fe-reviewer·fe-perf-auditor 는 그 파일의 «공통 규칙» 절 + 해당 프레임워크 절을 판정 근거로 쓴다(소비자 프로젝트 CLAUDE.md 가 우선). 에이전트는 플러그인 트리 위치를 모르므로 경로 없이 위임하면 내장 기준만으로 판정하고 그 사실을 보고 첫 줄에 적는다. 모노레포면 ../../docs/monorepo.md 경로도 넘긴다.

형식:

## 코드 리뷰 결과

### BLOCK (커밋 전 반드시 수정)
- [축] file:line — 문제
  - Before: ...
  - After: ...

### WARN (권장 수정)
- [축] file:line — 문제

### INFO (참고)
- [축] file:line — 내용

---
요약: BLOCK N개 / WARN N개 / INFO N개 · 테스트 exit N (Pass/Fail) · 추가 감사 BLOCK N개
전부 0 이면 "커밋 준비 완료", 하나라도 남으면 "N개 수정 후 재검토"

BLOCK 항목이 있으면 수정 후 에이전트 재위임합니다.

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.
