What is google-cloud-storage?

A Google Cloud Storage add-on for managing buckets and stored objects, which are files kept in Google's cloud. It also includes guidance for transfers, access permissions, security, lifecycle rules, signed URLs, Terraform, and command-line use.

Use it to manage Google Cloud Storage buckets and objects, configure access and retention, transfer files, create signed URLs, or work with Terraform and the command line.

It brings storage operations and configuration into the coding agent, reducing the need to switch between separate cloud tools and documentation.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/gemini-cli-extensions/google-cloud-storage

Made for: Gemini CLI.

Security

Grade A, and why

google-cloud-storage scanned grade A with 0 findings 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 13d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
