container-escape-techniques

container-escape-techniques is a skill for Claude Code, Codex from Prohao42/aimy-skill. It costs 52 tokens per session (2,687 once invoked), scanned C, original, no licence file.

A guide to container escape, where code running inside Docker, LXC, or a Kubernetes pod reaches the host system outside the container.

In plain words
What is it for?
Use it to examine privileged containers, Linux capabilities, exposed Docker sockets, cgroups, namespaces, and container runtime vulnerabilities.
Why use it?
It helps assess whether container settings or runtime flaws allow isolation to be bypassed.

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 C, and why

container-escape-techniques scanned grade C with 2 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 6d 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.

Reaches for credential fileshighPrivilege escalation

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

What ships with it

1 file beside SKILL.md 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.

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.
