skills: Instructions file for Codex

AGENTS.md

skills AGENTS.md is an instructions file for Codex, OpenCode from DaleStudy/skills. It costs 1,565 tokens per session, scanned A, original, MIT.

Repository instructions for DaleStudy's collection of reusable skills for coding assistants such as Claude Code, Cursor, and GitHub Copilot. They explain the skill files, local installation tests, packaging, and automated checks.

In plain words
What is it for?
Developing, testing, packaging, and distributing skills, including running local installation checks and updating the continuous-integration skill list.
Why use it?
They show contributors how to add and verify skills in a content-only repository without a separate build process.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is DaleStudy/skills's own configuration. It tells Codex and OpenCode how to work on skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skills configures →

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

skills AGENTS.md 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 yesterday.

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.

Repository Overview

DaleStudy 커뮤니티의 Agent Skills 모음집. AI 코딩 어시스턴트(Claude Code, Cursor, GitHub Copilot)용 재사용 가능한 스킬 정의를 제공한다.

이 저장소는 빌드 과정 없는 순수 콘텐츠 저장소다. 각 스킬은 SKILL.md 파일로 정의되며, 배포 시 단순히 ZIP으로 압축되어 dist/ 디렉토리에 .skill 확장자로 저장된다.

Development Commands

스킬 테스트 (로컬)

# 로컬 저장소에서 특정 스킬 설치 테스트
npx skills add . --skill bun --agent claude-code --global --yes

# Bun 사용 시
bunx skills add . --skill bun --agent claude-code --global --yes

설치 후 ~/.agents/skills/{skill-name} 및 ~/.claude/skills/{skill-name} (심볼릭 링크)에서 확인 가능

배포 방식

이 저장소는 GitHub를 통해 직접 배포된다. npx skills add dalestudy/skills는:

  1. GitHub 저장소 클론
  2. skills/ 디렉토리에서 SKILL.md 파일 읽기
  3. 선택한 스킬을 ~/.agents/skills/에 설치

별도 빌드/패키징 과정 없음. skills/{skill-name}/SKILL.md 파일을 수정하면 즉시 배포된다.

CI 테스트

GitHub Actions가 자동으로 실행됨 (스케줄: 매일 11:00, 23:00 UTC):

  • skills/ 아래 모든 스킬의 설치 가능성 검증 (스킬을 추가해도 CI를 고칠 필요 없음)

Repository Architecture

스킬 구조

각 스킬은 Agent Skills 스펙을 따른다:

skills/{skill-name}/
└── SKILL.md          # YAML frontmatter + Markdown 지시사항 (필수)

핵심 원칙:

  • SKILL.md는 실행 가능한 지시사항이자 메타데이터를 포함
  • description 필드는 스킬 활성화 조건을 명확히 기술 (파일 패턴, 키워드, 사용 상황)
  • allowed-tools는 스킬이 요구하는 도구 권한을 선언 (예: Bash(bun:*))

SKILL.md 작성 규칙

---
name: skill-name
description: "스킬 설명 + 활성화 조건. 다음 상황에서 사용: (1) ..., (2) ..., (3) ..."
license: MIT
compatibility: 필요한 CLI 도구 (예: Requires bun CLI)
metadata:
  author: DaleStudy
  version: "1.0"
allowed-tools: Bash(command:*) Bash(another:*) # 공백으로 구분
---

# 스킬 제목

스킬 지시사항 (Markdown)

중요:

  • description은 AI 에이전트가 언제 이 스킬을 사용할지 판단하는 주요 기준
  • 구체적인 파일 패턴 (.stories.tsx), 키워드 (bun, CSF), 사용 상황을 명시
  • allowed-tools는 권한 프롬프트 최소화를 위해 정확히 기술

배포 구조

스킬은 GitHub 저장소를 통해 직접 배포된다:

npx skills add dalestudy/skills --skill bun

위 명령은:

  1. https://github.com/DaleStudy/skills 저장소 클론
  2. skills/bun/SKILL.md 파일 복사
  3. ~/.agents/skills/bun/에 설치

Changes

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.
