object-storage

object-storage is a skill for Claude Code, Codex from BagelHole/DevOps-Security-Agent-Skills. It costs 30 tokens per session (2,675 once invoked), scanned A, original, MIT.

A guide to object storage systems such as Amazon S3, Google Cloud Storage, and MinIO. Object storage keeps files such as backups, logs, media, and application assets in buckets rather than normal folders.

In plain words
What is it for?
Use it to create buckets, manage permissions and versions, configure lifecycle rules, run self-hosted MinIO, sync files, or serve static content.
Why use it?
It helps you control who can access stored files, automate expiration or archival, encrypt data, and move files between local and cloud storage.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is aws s3 cp s3://my-app-assets-prod/reports/report.pdf ./downloads/.

Good fit Use it to create buckets, manage permissions and versions, configure lifecycle rules, run self-hosted MinIO, sync files, or serve static content.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

object-storage scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Object Storage

Configure and manage object storage solutions including AWS S3, MinIO (self-hosted), and compatible providers. Covers CLI operations, bucket policies, lifecycle rules, versioning, encryption, and the MinIO client (mc).

When to Use

  • Storing application assets, backups, logs, or media files
  • Setting up an S3-compatible object store on-premises with MinIO
  • Configuring lifecycle rules to transition or expire objects automatically
  • Implementing access control with bucket policies and IAM
  • Syncing data between local filesystems and object storage
  • Serving static content from S3 or MinIO

Prerequisites

  • AWS CLI v2 installed and configured (aws configure) for S3 operations
  • Docker installed for MinIO self-hosted setup
  • MinIO client (mc) installed for MinIO management
  • IAM credentials with appropriate S3 permissions
  • Network access to the object storage endpoint

AWS S3 CLI Operations

Bucket Management

# Create a new bucket
aws s3 mb s3://my-app-assets-prod

# Create a bucket in a specific region
aws s3 mb s3://my-app-assets-eu --region eu-west-1

# List all buckets
aws s3 ls

# List objects in a bucket (with sizes)
aws s3 ls s3://my-app-assets-prod --recursive --human-readable --summarize

# Delete an empty bucket
aws s3 rb s3://my-old-bucket

# Delete a bucket and ALL its contents (destructive)
aws s3 rb s3://my-old-bucket --force

Upload and Download

# Upload a single file
aws s3 cp ./report.pdf s3://my-app-assets-prod/reports/

# Upload with a specific storage class
aws s3 cp ./archive.tar.gz s3://my-app-assets-prod/archives/ --storage-class GLACIER

# Upload with server-side encryption (AES-256)
aws s3 cp ./sensitive.dat s3://my-app-assets-prod/data/ --sse AES256

# Download a file
aws s3 cp s3://my-app-assets-prod/reports/report.pdf ./downloads/

# Sync a local directory to S3 (upload only changed files)
aws s3 sync ./build/ s3://my-app-assets-prod/static/ --delete

# Sync from S3 to local
aws s3 sync s3://my-app-assets-prod/static/ ./local-copy/

# Sync with exclusion patterns
aws s3 sync ./logs/ s3://my-app-logs/ --exclude "*.tmp" --exclude ".git/*"

# Copy between buckets
aws s3 sync s3://source-bucket/ s3://destination-bucket/ --source-region us-east-1 --region eu-west-1

# Generate a pre-signed URL (temporary access, 1 hour)
aws s3 presign s3://my-app-assets-prod/reports/report.pdf --expires-in 3600

# Recursive delete of a prefix
aws s3 rm s3://my-app-assets-prod/old-data/ --recursive

object-storage is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,084 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 2,675 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
