3. Quick Start

Invoke this skill by describing your analysis needs to Claude.

4. How It Works

Follow the skill’s SKILL.md workflow step by step, starting from a small validated input.

5. Usage Examples

  • AWS CLIコマンドの構文を知りたい
  • IAMポリシーやロールを設計・確認したい
  • EC2、S3、Lambdaなどのリソースを管理したい
  • クロスアカウントアクセスを設定したい
  • セキュリティ設定を確認・強化したい
  • AWS操作を自動化したい

6. Understanding the Output

  • A structured response or artifact aligned to the skill’s workflow.
  • Reference support from 3 guide file(s).
  • Reusable output that can be reviewed, refined, and incorporated into a wider project workflow.

7. Tips & Best Practices

  • Begin with the smallest realistic sample input so you can validate the workflow before scaling up.
  • Keep skills/aws-cli-expert/SKILL.md open while working; it remains the authoritative source for the full procedure.
  • Review the most relevant reference files first instead of scanning every guide: security_best_practices.md, iam_guide.md, aws_cli_essentials.md.
  • Preserve intermediate outputs so you can explain assumptions, diffs, and follow-up actions clearly.

8. Combining with Other Skills

  • Combine this skill with adjacent skills in the same category when the work spans planning, implementation, and review.
  • Browse the broader category for neighboring workflows: category index.
  • Use the English skill catalog when you need to chain this workflow into a larger end-to-end process.

9. Troubleshooting

  • Re-check prerequisites first: missing runtime dependencies and unsupported file formats are the most common failures.
  • If a helper script is involved, run it with a minimal sample input before applying it to a full dataset or repository.
  • Compare your input shape against the reference files to confirm expected fields, sections, or metadata are present.
