s3
AWS S3 object storage for bucket management, object operations, and access control. Use when creating buckets, uploading files, configuring lifecycle policies, setting up static websites, managing permissions, or implementing cross-region replication.
npx skills add itsmostafa/aws-agent-skills --skill s3 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# AWS S3 Amazon Simple Storage Service (S3) provides scalable object storage with industry-leading durability (99.999999999%). S3 is fundamental to AWS—used for data lakes, backups, static websites, and as storage for many other AWS services. ## Table of Contents - [Core Concepts](#core-concepts) - [Common Patterns](#common-patterns) - [CLI Reference](#cli-reference) - [Best Practices](#best-practices) - [Troubleshooting](#troubleshooting) - [References](#references) ## Core Concepts ### Buckets Containers for objects. Bucket names are globally unique across all AWS accounts. ### Objects Files stored in S3, consisting of data, metadata, and a unique key (path). Maximum size: 5 TB. ### Storage Classes | Class | Use Case | Durability | Availability | |-------|----------|------------|--------------| | Standard | Frequently accessed | 99.999999999% | 99.99% | | Intelligent-Tiering | Unknown access patterns | 99.999999999% | 99.9% | | Standard-IA | Infrequent access | 99.999999999% | 99.9% | | Glacier Instant | Archive with instant retrieval | 99.999999999% | 99.9% | | Glacier Flexible | Archive (minutes to hours) | 99.999999999% | 99.99% | | Glacier Deep Archive | Long-term archive | 9

What does the s3 skill do?
AWS S3 object storage for bucket management, object operations, and access control. Use when creating buckets, uploading files, configuring lifecycle policies, setting up static websites, managing permissions, or implementing cross-region replication.
How do I install it?
Run `npx skills add itsmostafa/aws-agent-skills --skill s3 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From itsmostafa/aws-agent-skills, a repository with 1,139 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
