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 pjt222/development-guides at bcca822c1c.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill
What it does
The create-dockerfile skill generates a Dockerfile based on provided specifications. It automates the creation of a basic Docker setup, including selecting a base image and defining common commands. This simplifies containerization for developers who may not be familiar with Dockerfile syntax or best practices.
When to use it
- Quickly set up a development environment: Generate a Dockerfile for a new project to streamline local development workflows.
- Containerize existing applications: Create a Dockerfile to package an application and its dependencies into a container image.
- Standardize build processes: Ensure consistent builds across different environments by automating Dockerfile creation.
- Simplify deployment: Use the generated Dockerfile as the foundation for deploying your application to cloud platforms or other container orchestration systems.
Key capabilities
- Dockerfile generation
- Base image selection
- Command definition within Dockerfile
Example prompts
- "Create a Dockerfile for a Python Flask application using the official Python 3.9 image."
- "Generate a Dockerfile that copies all files from the current directory into /app and runs 'npm install'."
- "I need a Dockerfile with a Node.js 16 base image, exposing port 3000."
Tips & gotchas
The skill assumes basic familiarity with containerization concepts. You'll likely need to adjust the generated Dockerfile further based on your application’s specific requirements and dependencies.
