docker-toolkit

docker-toolkit is a plugin for Claude Code from armanzeroeight/fastagent-plugins. Its manifest loads nothing; the 2 skills it bundles cost 76 tokens per session together, scanned A, original, MIT.

A Docker toolkit for improving container images, checking them for security issues, and following container best practices. Docker packages an application and its dependencies into portable containers.

In plain words
What is it for?
Use it to optimize Docker images, scan them for security issues, and make container architecture decisions.
Why use it?
It helps reduce unnecessary image contents and identify security problems before containers are used or deployed.

Security

Grade A, and why

docker-toolkit 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 yesterday.

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.

Contents

What it installs

The manifest is a name and a version. 2 skills travel with it, and installing the plugin installs all of them — 76 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#docker-toolkit in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
