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

사용 사례

실전 활용법: claude-skills

Get an architecture review before you commit to a stack

👤 Tech leads starting a new service ⏱ ~30 min intermediate

언제 쓸까: You're about to pick a framework and database for a new product and want a sanity check.

흐름

Describe the service

Use the engineering skills. We need a real-time collab API — 10k concurrent users, document sync, presence. Compare Node+WebSocket vs Elixir+Phoenix vs Go+gRPC.✓ 복사됨

→ Comparison grounded in real tradeoffs from the respective skills
Probe risks

For the choice you'd recommend, what fails at 100k users?✓ 복사됨

→ Concrete scaling cliffs, not generic platitudes

결과: A decision doc with tradeoffs and scaling risks identified.

함정

Skill over-recommends the framework it has the deepest skill for — Ask it to explicitly state why NOT each option

Run an incident response playbook for a production outage

👤 On-call engineers during a live incident ⏱ ~15 min advanced

언제 쓸까: Production is on fire and you need structured triage without panicking.

흐름

Open the incident

Use the incident-response skill. Symptoms: API 500s spiking in US-east, started 10 min ago.✓ 복사됨

→ Claude walks through structured diagnosis — triage tree, log queries, mitigation options
Follow-up postmortem

Now draft the postmortem template using what we learned.✓ 복사됨

→ Filled-in template with blameless framing

결과: Faster time-to-mitigate and a credible postmortem.

함정

Skill suggests generic mitigations without knowing your stack — Tell it your stack upfront — 'we're on AWS ECS + RDS Postgres'

함께 쓰기: aws · sentry

Use the CTO skill to pressure-test a board deck

👤 Founders and CTOs prepping for fundraising ⏱ ~45 min advanced

언제 쓸까: You have the tech section of a deck and want senior-CTO red team feedback.

흐름

Share the slides

Use the CTO advisory skill. Here's our tech architecture slide — what would a skeptical board member ask?✓ 복사됨

→ Specific, pointed questions tied to slide content
Prep answers

For each question, draft a crisp answer with data we'd need to back it up.✓ 복사됨

→ Prep notes you can actually rehearse

결과: A rehearsed Q&A for the tech portion of your board meeting.

함정

Questions feel generic — Feed in your actual architecture docs, not just the deck summary

조합

다른 MCP와 조합해 10배 효율

claude-skill + github

Engineering skills suggest the change; GitHub MCP opens the PR

Use the backend skill to design the refactor, then open a PR in our repo with the plan as the description.✓ 복사됨

claude-skill + filesystem

Skills produce docs; filesystem stores them in the repo

Save the architecture review output to docs/architecture/ and create a README index.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
Engineering skills	technical question or design brief	Backend, frontend, DevOps, security work
Marketing skills	campaign or content brief	Content, SEO, CRO, growth work
C-Level advisory skills	strategic question	Board, fundraising, executive hiring
POWERFUL Tier skills	complex scenario (RAG, DB, incident)	When a basic skill isn't enough
Regulatory/quality skills	compliance question	Regulated industries

비용 및 제한

운영 비용

API 쿼터: None
호출당 토큰: Varies wildly by skill; big skills load 5-15k tokens of references
금액: Free — skills are local
팁: The library is too big to let Claude browse freely. Name the skill or domain in the prompt.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials — skill is prompts

데이터 외부 송신: None from the skill itself

C-level and regulatory skills still need human review — don't ship compliance decisions on skill output alone.

문제 해결

자주 발생하는 오류와 해결

Claude picks the wrong skill for a task

Reference by domain: 'use the marketing > SEO skill'. With 235+ skills, auto-routing is fuzzy.

SKILL.md loads are too large

Pin to one skill at a time; don't try to load multiple domains in one prompt.

Python CLI helpers not found

Some skills require optional Python utils — check the skill's setup section.

대안

claude-skills 다른 것과 비교

대안	언제 쓰나	단점/장점
claude-skill-2 (Jeffallan)	You only want full-stack dev (66 skills), not marketing/compliance	Narrower, less overwhelming
awesome-claude-skill	You want to browse skills, not install a mega-bundle	Directory vs installable pack
Single-purpose skills (terraform, playwright, tutor)	You have one specific problem	Sharper focus
