aws-agent-skills

왜 쓰나요

핵심 기능

18 core AWS services covered (IAM, Lambda, DynamoDB, S3, API Gateway, EC2, ECS, EKS, CFN, CloudWatch, RDS, SQS, SNS, Cognito, Step Functions, Secrets Manager, EventBridge, Bedrock)
Each SKILL.md includes CLI reference with real flags, not guessed ones
Common-pattern section per service surfaces production idioms
Security best-practices baked in (least-privilege IAM, encryption defaults)
Metadata tracks last-updated so you know the reference's freshness

실전 활용법: aws-agent-skills

Write a least-privilege IAM policy for a Lambda + DynamoDB pair

👤 Backend engineers setting up AWS resources ⏱ ~15 min intermediate

언제 쓸까: You're wiring a Lambda to a Dynamo table and don't want to give it * permissions.

흐름

State the access needed

Use the aws iam + lambda skills. Write a policy for a Lambda that needs GetItem and UpdateItem on table Orders and nothing else.✓ 복사됨

→ Policy with exact actions + resource ARN, no wildcards
Test

Give me the aws iam simulate-custom-policy command to verify this allows only those two actions.✓ 복사됨

→ Runnable command with correct syntax

결과: A production-quality least-privilege IAM policy with verification.

함정

Policy uses wildcards for convenience — Insist on exact resource ARNs — skill supports this strongly

함께 쓰기: terraform-skill

Design an EventBridge → Step Functions → Lambda pipeline

👤 Serverless engineers ⏱ ~40 min advanced

언제 쓸까: You need an event-driven workflow and want the right service boundaries.

흐름

Sketch the flow

Use the eventbridge + step-functions + lambda skills. Design a pipeline that triggers on S3 uploads, orchestrates 3 steps, and writes to DynamoDB.✓ 복사됨

→ Architecture diagram + IaC snippets
Observability

Now add CloudWatch alarms and structured logging.✓ 복사됨

→ Specific metric filters and alarm thresholds

결과: A buildable serverless architecture with monitoring.

함정

Step Functions costs explode at scale — Skill flags when Express workflows fit better than Standard

함께 쓰기: terraform-skill

Scaffold a Bedrock-backed RAG service

👤 Engineers building LLM features on AWS ⏱ ~60 min advanced

언제 쓸까: You want to use Bedrock for embeddings + generation without piecing it together from blog posts.

흐름

Describe the service

Use the bedrock + s3 + dynamodb skills. Scaffold a RAG service: upload docs to S3, embed with Titan, store in DynamoDB, retrieve + generate at query time.✓ 복사됨

→ Runnable code with correct Bedrock invoke calls and embedding model IDs

결과: A first-pass RAG scaffold on AWS-native services.

함정

Using Dynamo for vector search at scale — Skill notes when OpenSearch or pgvector is a better fit

조합

다른 MCP와 조합해 10배 효율

aws-agent-skill + terraform-skill

AWS skills propose the design; Terraform skill writes the HCL

Design the Lambda+Dynamo stack using the aws skills, then have terraform-skill write the module.✓ 복사됨

aws-agent-skill + aws

Skill tells Claude the right calls; AWS MCP actually runs them

Use the aws-agent-skills to design the policy, then apply it via the aws MCP.✓ 복사됨

도구

Bedrock skill	LLM use case	Using AWS-native GenAI

비용 및 제한

운영 비용

API 쿼터: None for the skill
호출당 토큰: 3-8k per service loaded
금액: Free — skill is local. AWS usage costs are yours.
팁: Name the services you're using so Claude loads only those SKILL.md files.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials in the skill. Real AWS calls should use OIDC roles, not static keys.

데이터 외부 송신: None from the skill itself

Double-check generated IAM policies before deploying — the skill aims for least-privilege but you know your workload best.

문제 해결

자주 발생하는 오류와 해결

CLI flag rejected by actual AWS CLI

AWS occasionally renames flags. Check the service's last-updated metadata; cross-reference official docs if stale.

확인: aws <service> <command> help

Claude uses SDK v2 patterns for Python boto3

Boto3 is v1 (and stable); don't confuse with AWS SDK for JS v2/v3. Specify language explicitly.
