aws-storage

An agent skill by aws, from aws/agent-toolkit-for-aws. Tags: aws, cloud, cost-optimization, performance, storage.

What it does

Selects, investigates, and compares AWS object, file, and block storage services, and answers cost, performance, configuration, security, and troubleshooting questions about storage services. Applies when a user asks where to store or archive data based on their usage patterns; which storage service to choose or how two compare; how to migrate data from on-premises or between AWS services; how to protect, replicate, or recover data; how to optimize storage costs; where to deploy shared NFS, SMB, or POSIX file systems; where to store vector embeddings or tabular data; what storage backs enterprise file shares, self-managed databases on EC2, VMware, or stateful containers; or asks what an AWS storage service can do or how it works. Relevant for storage needs for workloads such as AI/ML, analytics, EDA, HPC, media, genomics, or financial trading. Not applicable for SQL query engines (Athena, Spark, Redshift, EMR), ETL (Glue), streaming (Kafka, MSK, Kinesis), or managed database services (RDS, Aurora, DynamoDB).

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add aws/agent-toolkit-for-aws --skill aws-storage

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/aws/agent-toolkit-for-aws
cp -r agent-toolkit-for-aws/plugins/aws-core/skills/aws-storage ~/.claude/skills/aws-storage

Safety box score

Grade A, minimal risk: 7 of 100 risk points, rated 2026-10-19. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This is a documentation-only AWS storage advisory skill: it selects and compares storage services, then tells the agent to verify current specs against AWS docs, pricing pages, or the AWS CLI. It does not ship runnable scripts, but it does steer the agent toward network lookups and potentially high-impact AWS storage operations such as migration, backup, and replication recommendations.

Category levels, from 0 (none) to 3 (high)
CategoryLevelWhy
Code & shell execution0 (none)No shipped scripts, shell commands, or code evaluators are present; the files are Markdown guidance only.
Network access1 (low)It requires live retrieval from AWS docs/pricing and may use the AWS MCP server or AWS CLI to confirm current values (`use search_documentation and read_documentation`, `use the AWS CLI`).
Filesystem reach0 (none)There are no commands or instructions to read, write, or delete local files outside the skill directory.
Secrets & credentials0 (none)The skill does not ask for passwords, tokens, key files, or pasted secrets, and it does not reference secret stores.
Privilege & persistence0 (none)No sudo, service installation, shell startup edits, or OS-level changes are requested.
Instruction hijack surface0 (none)I found no prompt-injection payloads, hidden text, or instructions to ignore higher-priority rules.
Irreversible actions1 (low)Its purpose includes recommending migrations, replication, backup, and data-transfer approaches, but it does not itself execute those actions.
Transparency0 (none)All shipped content is readable Markdown; there are no binaries, blobs, or downloaded installers.
