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

About this skill
What it does
This skill provides access to and utilizes Ruby's standard library. It enables AI agents to perform common programming tasks, manipulate strings, work with dates and times, and interact with files – all using built-in Ruby functionality. The agent can leverage this for data processing, scripting, and automating various workflows.
When to use it
- Data Transformation: When needing to clean or reformat text data (e.g., extracting specific information from a log file).
- File Management: For tasks like creating, reading, writing, or deleting files and directories.
- Date/Time Calculations: When dealing with scheduling events or calculating time differences.
- String Manipulation: For parsing user input or generating formatted output.
Key capabilities
- Access to Ruby's core libraries (e.g.,
string,date,file). - Ability to perform string operations like splitting, joining, and searching.
- Date and time manipulation for calculations and formatting.
- File system interaction for reading and writing data.
Example prompts
- "Extract all email addresses from this text: [text content]"
- "Create a new file named 'report.txt' and write the current date and time to it."
- "Split this sentence into individual words: [sentence]"
Tips & gotchas
The agent needs access to a Ruby runtime environment to execute commands using this skill. Be mindful of potential security implications when working with files, especially in production environments.
