docker

docker is an agent for Claude Code from ASCIT31/Dark-Moon. It costs 43 tokens per session (6,187 once invoked), scanned B, original, GPL-3.0.

An autonomous security-testing sub-agent for an exposed Docker Engine API, the interface used to manage Docker containers. It works with Docker images, containers, and possible container-to-host escape paths.

In plain words
What is it for?
Use it to perform penetration testing of exposed Docker Engine APIs and investigate images, containers, and possible paths from a container to its host.
Why use it?
It is intended to examine Docker access that may be reachable through a Unix socket or an unauthenticated network port, helping identify serious exposure risks.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to perform penetration testing of exposed Docker Engine APIs and investigate images, containers, and possible paths from a container to its host.

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 B, and why

docker scanned grade B with 3 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 1mo 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -s --unix-socket /var/run/docker.sock -X POST http://localhost/containers/create -H 'Content-Type: application/json' -d '{"Image":"<local_image>","Cmd":["sleep","60"],"HostConfig":{"Binds":["/:/host"],"Privileged":t

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

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.

docker is an agent published in the GitHub repository ASCIT31/Dark-Moon (1,028 stars, last pushed 15d ago), licensed GPL-3.0. It adds 43 tokens to every session and 6,187 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 3 findings (sends data to an external url, reaches for credential files, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
