Install Arg Parser Generator

skills CLI
$ npx skills add revfactory/harness-100 --skill arg-parser-generator -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install revfactory/harness-100 arg-parser-generator --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/revfactory/harness-100.git skills-src && mkdir -p .claude/skills && cp -r skills-src/ko/40-cli-tool-builder/.claude/skills/arg-parser-generator .claude/skills/arg-parser-generator && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

CLI 도구의 인자 파서 구조를 체계적으로 설계하고 코드를 생성하는 방법론. An agent skill from revfactory/harness-100.

  • SKILL.md covers 대상 에이전트, CLI 인자 유형 분류, 서브커맨드 설계 패턴 and 옵션 네이밍 규칙, plus 3 more sections
  • Needs API_KEY

What it does

Arg Parser Generator is an agent skill from revfactory/harness-100. CLI 도구의 인자 파서 구조를 체계적으로 설계하고 코드를 생성하는 방법론. 'CLI 인자 설계', '옵션 구조', '서브커맨드 설계', '인자 파서 생성', '도움말 설계' 등 CLI 인자 체계 설계 시 사용한다. 단, GUI 인터페이스 설계, TUI 프레임워크 통합은 이 스킬의 범위가 아니다.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

Example prompts

  • “CLI 인자 설계”
  • “/arg-parser-generator”

Requirements

  • Python 3
  • Node.js
  • A credential in API_KEY

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python, javascript and go).

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • API_KEY

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

Context cost

Arg Parser Generator loads about 952 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 143 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~952

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.

CLI 도구의 인자 파서 구조를 체계적으로 설계하고 코드를 생성하는 방법론. 'CLI 인자 설계', '옵션 구조', '서브커맨드 설계', '인자 파서 생성', '도움말 설계' 등 CLI 인자 체계 설계 시 사용한다. 단, GUI 인터페이스 설계, TUI 프레임워크 통합은 이 스킬의 범위가 아니다.

Arg Parser Generator — CLI 인자 파서 설계 + 코드 생성

command-designer와 core-developer의 인자 파서 설계를 강화하는 스킬.

대상 에이전트

  • command-designer — 명령 체계와 옵션 구조를 설계한다
  • core-developer — 인자 파서 코드를 구현한다

CLI 인자 유형 분류

유형형식예시
위치 인자<arg>convert input.json
필수 옵션--name VALUE--output out.yaml
선택 옵션[--name VALUE][--indent 2]
플래그[--flag][--verbose]
다중 값--name V1 V2--files a.txt b.txt
열거형--type {a,b,c}--format {json,yaml}
환경변수$ENV_VAR$API_KEY

서브커맨드 설계 패턴

패턴 1: 동사형 (CRUD)
mytool create <resource> [options]
mytool list [resource] [--filter]
mytool get <id> [--format]
mytool update <id> [options]
mytool delete <id> [--force]
패턴 2: 리소스형 (kubectl 스타일)
mytool user list
mytool user create --name "name"
mytool project deploy --env prod
패턴 3: 파이프라인형 (Unix 철학)
mytool parse input.json | mytool transform --schema s.yaml | mytool output

옵션 네이밍 규칙

1. 짧은/긴 옵션 쌍: -o / --output
2. 불리언 + 부정: --color / --no-color
3. 일관된 명사: --output-dir (동사 X → --write-to X)
4. 축약 가능: --config → --cfg (혼동 없을 때)

금지 패턴:
- -h (help 예약), -V (version 예약)
- 대문자 단축옵션 (-A, -B) — 혼동 유발
- 너무 긴 옵션 (--output-directory-path)

언어별 파서 라이브러리 + 보일러플레이트

Python (typer — 권장)
python
import typer
from typing import Optional
from enum import Enum

app = typer.Typer(help="파일 변환 CLI")

class Format(str, Enum):
    json = "json"
    yaml = "yaml"
    toml = "toml"

@app.command()
def convert(
    input_file: str = typer.Argument(..., help="입력 파일"),
    from_format: Format = typer.Option(..., "--from", "-f", help="입력 형식"),
    to_format: Format = typer.Option(..., "--to", "-t", help="출력 형식"),
    output: Optional[str] = typer.Option(None, "--output", "-o", help="출력 파일"),
    indent: int = typer.Option(2, "--indent", help="들여쓰기"),
    verbose: bool = typer.Option(False, "--verbose", "-v", help="상세 로그"),
):
    """파일 형식을 변환합니다."""
    ...

if __name__ == "__main__":
    app()
Node.js (commander)
javascript
const { Command } = require('commander');
const program = new Command();

program
  .name('mytool')
  .description('파일 변환 CLI')
  .version('1.0.0');

program
  .command('convert <input>')
  .option('-f, --from <format>', '입력 형식', 'json')
  .option('-t, --to <format>', '출력 형식', 'yaml')
  .option('-o, --output <file>', '출력 파일')
  .action((input, options) => { ... });

program.parse();
Go (cobra)
go
var convertCmd = &cobra.Command{
    Use:   "convert [input]",
    Short: "파일 형식 변환",
    Args:  cobra.ExactArgs(1),
    RunE: func(cmd *cobra.Command, args []string) error {
        from, _ := cmd.Flags().GetString("from")
        to, _ := cmd.Flags().GetString("to")
        // ...
        return nil
    },
}

func init() {
    convertCmd.Flags().StringP("from", "f", "json", "입력 형식")
    convertCmd.Flags().StringP("to", "t", "yaml", "출력 형식")
    convertCmd.Flags().StringP("output", "o", "", "출력 파일")
}

도움말 출력 표준

Usage: mytool <command> [options]

  convert    파일 형식 변환
  validate   파일 유효성 검사
  diff       두 파일 비교

Options:
  -h, --help       도움말 표시
  -V, --version    버전 표시
  -v, --verbose    상세 출력
  --no-color       색상 비활성화

Examples:
  mytool convert input.json --to yaml
  mytool validate schema.json data.json

Environment:
  MYTOOL_CONFIG    설정 파일 경로
