docker-ops

docker-ops is a skill for Claude Code from NeverSight/learn-skills.dev. It costs 70 tokens per session (2,441 once invoked), scanned B, original, no licence file.

A guide to packaging applications in Docker containers, including Dockerfiles, Docker Compose, and multi-stage builds.

In plain words
What is it for?
Use it to build or run containers, write Dockerfiles, configure Compose services, improve image caching, add health checks, or apply container security practices.
Why use it?
It helps create smaller, more reliable, and safer container images using established configuration patterns.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is COPY src/ ./src/.

Good fit Use it to build or run containers, write Dockerfiles, configure Compose services, improve image caching, add health checks, or apply container security practices.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-ops 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 5d 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.

Asks for rootlowPrivilege escalation

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

| User | `USER nonroot` (create if needed) | Run as root in production |

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

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

| Package install | `apt-get update && apt-get install -y ... && rm -rf /var/lib/apt/lists/*` | Separate `RUN` for update and install |

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.

docker-ops is a skill published in the GitHub repository NeverSight/learn-skills.dev (209 stars, last pushed today), with no licence file. It adds 70 tokens to every session and 2,441 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 3 findings (asks for root, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
