Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed
Scanned pluginagentmarketplace/custom-plugin-docker at d417263e40.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill
What it does
This skill enables the creation of Docker images using multi-stage builds. It allows for optimizing image size by separating build dependencies from runtime requirements, resulting in smaller and more efficient container deployments. The skill can automate the generation of Dockerfile instructions to achieve this separation.
When to use it
- You need to reduce the size of your Docker images.
- Your application requires different tools during compilation than what's needed at runtime (e.g., compilers, testing frameworks).
- You want to streamline your Docker build process by automating multi-stage build configuration.
- You are deploying applications where image size and efficiency are critical factors.
Key capabilities
- Generates
Dockerfileinstructions for multi-stage builds. - Separates build dependencies from runtime environment.
- Optimizes Docker image sizes.
- Automates the creation of complex Dockerfile structures.
Example prompts
- "Create a Dockerfile with a multi-stage build for a Go application."
- "Generate a Dockerfile that uses a Node.js builder stage and a lightweight Alpine Linux runtime stage."
- “Show me how to create a docker file using multi-stage builds for a Python project.”
Tips & gotchas
The skill assumes basic familiarity with Docker concepts and Dockerfile syntax. Ensure you have the necessary build tools installed on your system if you are manually modifying generated files.
