hardening-docker-daemon-configuration

hardening-docker-daemon-configuration is a skill for Claude Code from balsm-health/Balsm-AI. It costs 36 tokens per session (2,182 once invoked), scanned B, original, no licence file.

A procedure for securing the Docker daemon, the background service that runs Docker containers. It covers user isolation, encrypted authentication, rootless operation, and CIS security checks.

In plain words
What is it for?
Use it when configuring Docker daemon.json and applying these listed security controls.
Why use it?
It helps reduce the risk that a compromised container or connection could gain excessive access to the host system.

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

hardening-docker-daemon-configuration 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 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 to the 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

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.

hardening-docker-daemon-configuration is a skill published in the GitHub repository balsm-health/Balsm-AI (2 stars, last pushed 1mo ago), with no licence file. It adds 36 tokens to every session and 2,182 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
