What it does

Ats Optimizer is an agent skill from revfactory/harness-100. ATS(지원자추적시스템) 통과 최적화를 위한 이력서 키워드 전략과 형식 가이드를 제공하는 전문 스킬. resume-writer 에이전트가 ATS 친화적인 이력서를 작성하고 JD 매칭률을 극대화할 때 활용한다. 'ATS 최적화', '이력서 키워드', 'JD 매칭', '이력서 형식', 'applicant tracking system', '서류 통과율' 등의 맥락에서 자동 적용한다. 단, ATS 소프트웨어(Workday, Greenhouse) 직접 접속이나 실제 채용 프로세스 대행은 이 스킬의 범위가 아니다.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Resume and CV writing and Recruiting and HR. It works with Workday. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Resume and CV writing
  • Tasks that involve Recruiting and HR

Example prompts

  • “ATS 최적화”
  • “applicant tracking system”
  • “/ats-optimizer”

Requirements

  • Python 3
  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • aws

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use aws, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ats Optimizer loads about 787 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~787

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ATS 파싱 원리

ATS가 읽는 방식
1. 텍스트 추출 (PDF/DOCX → Plain Text)
2. 섹션 인식 (경력, 학력, 기술 등)
3. 키워드 추출 + 빈도 분석
4. JD 키워드와 매칭 스코어 산출
5. 순위화하여 채용 담당자에게 제출

- 수상 / Awards

키워드 최적화 전략

JD 키워드 추출 프로세스
1. JD 전문을 복사한다
2. 다음 유형의 키워드를 추출한다:
   - Hard Skills: 프로그래밍 언어, 도구, 프레임워크
   - Soft Skills: 리더십, 커뮤니케이션, 문제해결
   - Industry Terms: 도메인 전문 용어
   - Action Verbs: 설계, 구축, 최적화, 리드
   - Qualifications: 학위, 자격증, 경력 연수
3. 빈도를 세어 우선순위를 매긴다
4. 이력서에 자연스럽게 반영한다
키워드 밀도 가이드
키워드 유형권장 횟수배치 위치
JD 핵심 키워드 (3-5개)2-3회요약, 경력, 기술
JD 보조 키워드 (5-10개)1-2회경력, 프로젝트
산업 용어1회자연스럽게 분산
키워드 매칭 방법
JD 표현이력서 반영원칙
"Python 경험 필수""Python으로 데이터 파이프라인 구축"행동+결과
"팀 리딩 경험""5명 개발팀 리드, 프로젝트 3건 완수"정량화
"CI/CD 경험""Jenkins/GitHub Actions 기반 CI/CD 파이프라인 구축 및 운영"구체적 도구

성과 정량화 공식 (STAR-Q)

정량화 패턴
[Action Verb] + [구체적 활동] + [정량적 결과]

예시:
- "설계 및 구축한 API 서버로 응답 시간 40% 단축, 일일 처리량 100만 건 달성"
- "코드 리뷰 프로세스 도입으로 배포 후 버그 60% 감소"
- "5명 규모 팀 리드하여 3개월 내 MVP 출시, 사용자 5,000명 확보"
정량화 가능한 지표 유형
카테고리지표 예시
성능응답시간, 처리량, 에러율, 가용성
효율시간 절감, 비용 절감, 자동화율
규모사용자 수, 트래픽, 데이터 크기

비즈니스매출 기여, 고객 유치, 전환율

이력서 섹션별 ATS 최적화

Professional Summary (3-4줄)
[직함/역할] + [핵심 경력] + [차별화 역량] + [정량 실적]

예시:
"7년차 백엔드 개발자로 대규모 트래픽 처리 시스템 설계 및 운영 경험.
Java/Spring Boot 기반 마이크로서비스 아키텍처 설계,
일일 1억 건 트랜잭션 처리 시스템 구축.
AWS 기반 인프라 최적화로 운영 비용 35% 절감."
