github/generate-custom-instructions-from-codebase

GitHub Copilot을 위한 마이그레이션 및 코드 진화 명령어 생성기입니다. 두 프로젝트 버전(브랜치, 커밋 또는 릴리스) 간의 차이점을 분석하여 기술 마이그레이션, 주요 리팩터링 또는 프레임워크 버전 업그레이드 중에 Copilot이 일관성을 유지할 수 있도록 정확한 명령어를 만듭니다.

generate-custom-instructions-from-codebase란 무엇인가요?

이 스킬은 GitHub Copilot 사용자가 프로젝트의 이전 버전과 이후 버전(예: 브랜치, 커밋, 또는 릴리스 태그) 간의 차이점을 분석하여, Copilot이 새로운 코드베이스 컨텍스트에서 올바르고 일관된 코드를 생성하도록 돕는 사용자 지정 명령어를 자동으로 생성합니다. 대규모 기술 스택 마이그레이션(예: Python 2 → 3, React 클래스형 → 함수형 컴포넌트)이나 프레임워크 업그레이드 시에 특히 유용하며, 수동으로 변경 사항을 문서화하는 수고를 없애줍니다. 사용자는 단순히 비교할 두 버전(예: `main` 브랜치와 `release/v2` 브랜치)을 지정하면, 스킬이 변경된 파일, API 호출, 패턴, 설정 등을 분석하여 Copilot의 `.github/copilot-instructions.md` 파일에 직접 적용 가능한 마크다운 형식의 명령어를 생성합니다. 이는 GitHub Copilot 플랫폼을 위한 것이며, 팀 전체가 일관된 코딩 가이드를 유지하면서 빠르게 진화하는 프로젝트에서 생산성을 크게 향상시킵니다.

generate-custom-instructions-from-codebase은(는) 무엇을 하나요?

마이그레이션 및 코드 진화 명령어 생성기 (GitHub Copilot 전용). 두 프로젝트 버전(브랜치, 커밋 또는 릴리스) 간의 차이점을 분석하여 기술 마이그레이션, 주요 리팩터링 또는 프레임워크 버전 업그레이드 중에 Copilot이 일관성을 유지할 수 있도록 정확한 명령어를 만듭니다.

사용 방법

이 스킬은 저장소 루트에서 실행되어야 합니다.

  1. 이전 버전 지정과 이후 버전 지정의 두 단계로 구성됩니다. 각 단계는 브랜치, 커밋 SHA, 또는 릴리스 태그가 될 수 있습니다.
  2. 스킬이 git diff를 사용하여 변경 사항을 분석합니다.
  3. 분석 결과를 바탕으로 .github/copilot-instructions.md 파일에 들어갈 내용을 생성합니다.

예시

1단계: 이전 버전 = main
2단계: 이후 버전 = release/v2

생성되는 명령어

생성되는 명령어는 다음을 포함합니다:

  • 더 이상 사용되지 않거나 변경된 API 호출
  • 새로운 코드 패턴 및 관례
  • 변경된 설정 또는 환경 변수
  • 리팩터링 지침
  • 새로운 종속성 사용법

제한 사항

  • 이 스킬은 Git 저장소에서 작동하며, 현재 디렉토리가 Git 저장소의 일부여야 합니다.
  • 정확한 diff를 위해 두 버전 간의 공통 조상이 필요합니다.
  • 대규모 diff(수천 개의 파일)의 경우 분석에 시간이 오래 걸릴 수 있습니다.

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

github/acquire-codebase-knowledge

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like "map this codebase", "document this architecture", "onboard me to this repo", or "create codebase docs". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

github/add-educational-comments

Add educational comments to the file specified, or prompt asking for file to comment if one is not provided.

github/agent-governance

Patterns and techniques for adding governance, safety, and trust controls to AI agent systems. Use this skill when: - Building AI agents that call external tools (APIs, databases, file systems) - Implementing policy-based access controls for agent tool usage - Adding semantic intent classification to detect dangerous prompts - Creating trust scoring systems for multi-agent workflows - Building audit trails for agent actions and decisions - Enforcing rate limits, content filters, or tool restrictions on agents - Working with any agent framework (PydanticAI, CrewAI, OpenAI Agents, LangChain, AutoGen)

github/agentic-eval

Patterns and techniques for evaluating and improving AI agent outputs. Use this skill when: - Implementing self-critique and reflection loops - Building evaluator-optimizer pipelines for quality-critical generation - Creating test-driven code refinement workflows - Designing rubric-based or LLM-as-judge evaluation systems - Adding iterative improvement to agent outputs (code, reports, analysis) - Measuring and improving agent response quality

github/agent-owasp-compliance

Check any AI agent codebase against the OWASP Agentic Security Initiative (ASI) Top 10 risks. Use this skill when: - Evaluating an agent system's security posture before production deployment - Running a compliance check against OWASP ASI 2026 standards - Mapping existing security controls to the 10 agentic risks - Generating a compliance report for security review or audit - Comparing agent framework security features against the standard - Any request like "is my agent OWASP compliant?", "check ASI compliance", or "agentic security audit"
