The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 19
Best Practices: Follow Docker and container security standards
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Container Optimization
I'll optimize your Docker containers and Dockerfiles for size reduction, faster builds, better layer caching, and improved security.
Arguments: $ARGUMENTS - Dockerfile path or specific optimization focus areas
Optimization Philosophy
- Multi-Stage Builds: Separate build and runtime dependencies
- Layer Caching: Optimize layer order for faster rebuilds
- Image Size: Minimize final image size
- Security: Scan for vulnerabilities in base images
- Best Practices: Follow Docker and container security standards
Token Optimization
Expected range: 400–2,000 tokens (initial), 200 tokens (cache hit)
Caching: Caches Dockerfile analysis in .claude/cache/container-optimize/dockerfiles.json for 7 days. Invalidated when Dockerfiles change.
Early exit: Returns immediately if all Dockerfiles are already optimally configured.
Patterns used: Grep-before-Read, early exit, template-based generation, caching
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
