docker_optimization

docker_optimization is a skill for Claude Code, Codex from vuralserhat86/antigravity-agentic-skills. It costs 0 tokens per session (4,568 once invoked), scanned B, original, no licence file.

A set of practices for making Docker images—the files used to package an application and its runtime—smaller, faster to build, and safer.

In plain words
What is it for?
Use it when creating or improving Dockerfiles, setting up multi-stage builds, reusing cached build layers, reducing image size, or hardening container images.
Why use it?
It helps reduce unnecessary files and repeated build work while addressing common container security issues.

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_optimization 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 8d 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.

### Don't Run as Root

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.

&& rm -rf /var/lib/apt/lists/*

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_optimization is a skill published in the GitHub repository vuralserhat86/antigravity-agentic-skills (42 stars, last pushed 8mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 4,568 tokens. 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 2026-08-30.
