Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add agent-skills-nix-skill -- git clone https://github.com/Kyure-A/agent-skills-nix ~/.claude/skills/agent-skills-nix

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: agent-skills-nix

How to declare your Claude skills in a Nix flake

👤 NixOS / Home Manager users ⏱ ~25 min intermediate

언제 쓸까: You want your Claude skill set tracked the same way as your shells, editors, and services.

사전 조건

Nix with flakes enabled — echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf
The flake added as an input — flake input agent-skills-nix.url = "github:Kyure-A/agent-skills-nix";

흐름

Add the input

Add agent-skills-nix to my flake inputs and wire it into Home Manager.✓ 복사됨

→ flake.nix updated with the input + module import
List the skills I want

Declare the skills I use: linear-claude-skill, symfony-ux-skills, mck-ppt-design-skill. Pin to current main.✓ 복사됨

→ A skills = { ... }; block with pinned revs
Build and switch

Run home-manager switch and verify ~/.claude/skills/ is populated.✓ 복사됨

→ All skills present as symlinked directories

결과: Reproducible skill set managed by Nix — wipe your dotfiles and get the same setup back in one command.

함정

Upstream skill changes break your workflow — Pin to a specific rev, only bump on purpose

함께 쓰기: filesystem

Sync the same skill set across laptop and workstation

👤 Multi-machine developers ⏱ ~15 min intermediate

언제 쓸까: You switch between a laptop and a desktop and keep forgetting to clone the same skills on both.

흐름

Add to your shared HM module

Move the skills declaration into my shared home-manager module so both hosts import it.✓ 복사됨

→ Single source of truth, two hosts consuming it
Switch both hosts

Build and switch on both machines.✓ 복사됨

→ Matching ~/.claude/skills/ on both

결과: Both machines carry the same skill bundle automatically.

함정

Forgetting to commit and push before switching on the second machine — Use a self-flake with autoCommit or a shared git repo

조합

다른 MCP와 조합해 10배 효율

agent-skills-nix-skill + filesystem

Claude reads your flake and suggests skills to add/remove

Read my flake.nix, check which of my installed skills haven't been used in 30 days, and suggest removals.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
skill-declaration	set of { name, url, rev }	During home-manager switch / nixos-rebuild	nix build runtime
lock-management	flake.lock	When you want deterministic upgrades	0

비용 및 제한

운영 비용

API 쿼터: none
호출당 토큰: minimal — Nix declarations are short
금액: free
팁: Keep your skill set small — every skill costs context tokens at load time

보안

권한, 시크릿, 파급범위

자격 증명 저장: none

데이터 외부 송신: fetches only the skill repos you declare

Nix fetches from the git URLs you declare — vet the source before adding to your flake

문제 해결

자주 발생하는 오류와 해결

Flake doesn't evaluate

Check input url format and run nix flake check for specific errors.

확인: nix flake check

Skills dir empty after switch

Make sure the module is actually imported in your HM config, and home.activation is running.

확인: ls ~/.claude/skills/

Pinned rev 404

The upstream repo may have rewritten history — update the rev.

대안

agent-skills-nix 다른 것과 비교

대안	언제 쓰나	단점/장점
manual git clone	You're not on Nix and don't want to be	No reproducibility; easy drift
agent-skills-cli-skill	You want a CLI installer without Nix	Imperative rather than declarative
