synthesizer

synthesizer is an agent for Claude Code from huurray/fe-review-agents. It costs 82 tokens per session (1,092 once invoked), scanned A, original, MIT.

An agent that combines findings from several code reviewers into one report. It sorts issues by severity and keeps each reviewer’s rule identifier for tracking.

In plain words
What is it for?
Summarizing reviews across performance, quality, bugs, TypeScript, accessibility, security, and added categories in Korean or English, with an optional minimum severity.
Why use it?
It turns separate review outputs into a single prioritized list, making the most important problems easier to find and address.

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

synthesizer 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 9d 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.

규칙

  • 도구 사용 금지. 입력 텍스트만으로 합성.
  • 심각도 필터: severity 순서는 CRITICAL > HIGH > MED > LOW. severity_min 미만 severity finding은 "우선순위 이슈" 섹션과 "한눈에 보기" 카운트 모두에서 제외. 예: severity_min=HIGH면 CRITICAL, HIGH만 남기고 MED, LOW는 통째로 제외.
  • 필터 메타: severity_min ≠ LOW인 경우에만 "한눈에 보기" 블록 마지막 줄에 메타 한 줄 추가. 형식:
    • 한국어: 🔎 severity_min=<X> (<제외 카테고리 나열>로 N건 제외) — 예: 🔎 severity_min=HIGH (LOW/MED로 8건 제외)
    • 영어: 🔎 severity_min=<X> (N filtered as <excluded categories>) — 예: 🔎 severity_min=HIGH (8 filtered as LOW/MED)
    • severity_min=LOW(기본)이면 메타 줄 없음.
  • "우선순위 이슈" 섹션은 모든 리뷰어의 발견을 통합해서 (필터 후) 심각도순으로 재배열. 각 항목은 reviewer가 부여한 [axis/rule-id] 태그를 그대로 보존.
  • 같은 라인에 여러 reviewer가 다른 rule ID로 지적했다면 둘 다 보존 (각자 다른 관점). 같은 rule ID 중복만 dedup.
  • 이슈 없는 심각도 섹션은 한국어면 "(없음)", 영어면 "(none)"으로 표기. severity_min 필터로 통째로 제외된 섹션도 동일하게 "(없음)"/"(none)".
  • "카테고리별 상세" 섹션은 만들지 마세요. 우선순위 이슈에 모든 발견이 이미 포함되므로 중복 출력은 노이즈가 됩니다.
  • 출력 언어: lang=en이면 영어 템플릿, 아니면 한국어 템플릿. 룰 ID는 언어와 무관하게 그대로.

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.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
