SKILL.md

한국어 글자 수 세기

What this skill does

자기소개서, 지원서, 자유서술형 폼처럼 글자 수 제한이 중요한 한국어 텍스트를 대상으로 LLM 추정 없이 결정론적으로 카운트한다.

  • 기본 글자 수: Intl.Segmenter 기반 Unicode extended grapheme cluster
  • 줄 수: CRLF, LF, CR, U+2028, U+2029 를 줄바꿈 1회로 계산
  • 기본 byte 수: UTF-8 실제 인코딩 길이
  • 호환 프로필: neis byte 규칙

When to use

  • "이 자기소개서 1000자 넘는지 정확히 세줘"
  • "이 텍스트를 UTF-8 byte 기준으로 계산해줘"
  • "줄 수랑 byte 수도 같이 알려줘"
  • "한글/영문/이모지 섞인 문장을 추정 말고 코드로 세줘"

Why this skill exists

  • 글자 수 제한은 1자 차이도 민감하다.
  • LLM이 글자 수를 눈대중으로 예측하면 재현성이 없다.
  • 이 스킬은 입력을 임의로 trim/정규화하지 않고, 문서화된 계약으로만 센다.

Contracts

default profile

  • characters: Intl.Segmenter("ko", { granularity: "grapheme" })
  • bytes: Buffer.byteLength(text, "utf8")
  • lines:
  • empty string => 0
  • non-empty => 줄바꿈 시퀀스 수 + 1
  • CRLF 는 2줄바꿈이 아니라 1줄바꿈으로 센다.

neis profile

  • characters: default 와 동일
  • lines: default 와 동일
  • bytes:
  • 한글 grapheme => 3B
  • ASCII grapheme => 1B
  • Enter/줄바꿈 시퀀스 => 2B
  • 그 외 문자는 UTF-8 byte 길이로 fallback

Prerequisites

  • node 18+
  • 설치된 skill payload 안에 scripts/korean_character_count.js helper 포함
  • 별도 API 키 없음

Workflow

  1. 텍스트를 직접 받거나 파일/STDIN으로 읽는다.
  2. node scripts/korean_character_count.js 로 결정론적 카운트를 실행한다.
  3. 필요한 프로필(default/neis)과 출력 형식(json/text)을 고른다.
  4. 결과를 그대로 반환하고, 어떤 계약으로 셌는지 함께 알려준다.

CLI examples

node scripts/korean_character_count.js --text "가나다"
node scripts/korean_character_count.js --text $'첫 줄\r\n둘째 줄🙂'
node scripts/korean_character_count.js --text $'첫 줄\n둘째 줄🙂' --profile neis --format text
node scripts/korean_character_count.js --file ./essay.txt --profile default
cat essay.txt | node scripts/korean_character_count.js --stdin --profile neis

Response policy

  • 추정하지 말고 helper 결과를 그대로 쓴다.
  • 어떤 profile로 셌는지 함께 보여준다.
  • 기본값이 필요하면 default profile을 사용한다.
  • 제출처가 NEIS/학교생활기록부 같은 별도 계약을 요구할 때만 neis 를 쓴다.

Done when

  • 글자 수, 줄 수, byte 수가 함께 반환된다.
  • default 와 neis 계약 차이가 문서에 명시된다.
  • node scripts/korean_character_count.js --help 가 동작한다.
  • 혼합 한국어/영문/공백/개행/emoji 입력에 대한 테스트가 있다.
