storage-s3-resiliency-expertiseS3 resiliency, security, and data protection review. An agent skill from aws/tools-for-devops-agent.
Storage S3 Resiliency Expertise is an agent skill from aws/tools-for-devops-agent, published by the product's own GitHub organization. S3 resiliency, security, and data protection review. Assesses one or many S3 buckets across nine dimensions — versioning, replication, object lock, encryption, block public access, bucket policy, ownership controls, server access logging, and static website hosting — using read-only control-plane API calls, then produces a rated report with prioritized findings and remediation guidance. Single-bucket and multi-bucket (fleet) reviews are routed automatically by input count. Use when a user asks to review, audit…
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including reference files (for example `.skilleval.yaml`, `CHANGELOG.md` and `README.md`).
It sits in DevOps & Cloud, covering File uploads and storage, Backup and disaster recovery and Privacy and GDPR. It works with Amazon S3 and Amazon Web Services. The repository describes itself as: Open-source tools for AWS DevOps Agent - extend DevOps Agent with ready-to-use skills, custom agents, and other tools, for incident response, root cause analysis, and operational…. The licence is Apache-2.0.
9 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit ddda70b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
s3.amazonaws.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Storage S3 Resiliency Expertise loads about 2.8k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 253 tokens; SKILL.md has 1,159 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md names no scripts, command-line tools or credentials: Storage S3 Resiliency Expertise is instructions for the agent only.
SKILL.md names 1 domain. In commands or code: s3.amazonaws.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Storage S3 Resiliency Expertise is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 18k tokens, read only when the agent opens those files.
