hardening-docker-containers-for-production

hardening-docker-containers-for-production is a skill for Claude Code from balsm-health/Balsm-AI. It costs 43 tokens per session (1,845 once invoked), scanned A, original, no licence file.

A security checklist for hardening Docker containers used in production, aligned with version 1.8 of the CIS Docker Benchmark. Docker containers package applications and their dependencies so they can run consistently.

In plain words
What is it for?
Use it to review and improve Docker container configurations before running them in production.
Why use it?
It helps reduce exposed attack surface, limit privilege escalation, and apply production container security practices.

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 A, and why

hardening-docker-containers-for-production scanned grade A 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- Root or sudo access on Docker host

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

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
