Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

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 mims-harvard/tooluniverse at f5c37eebeb.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The tooluniverse-custom-tool skill allows AI agents to execute custom tools. It provides a mechanism for extending the agent's capabilities beyond pre-built functions, enabling integration with specific workflows or systems. This tool can be used to call external APIs or run local scripts based on user instructions.

When to use it

  • Automating repetitive tasks: Integrate with internal systems to automate data entry or report generation.
  • Connecting to specialized services: Access and utilize functionalities from niche tools not natively supported by the agent.
  • Extending functionality for specific domains: Build custom actions tailored to a particular industry or application, like financial analysis or scientific research.
  • Running local scripts: Execute Python or other scripts directly within the AI agent's environment.

Key capabilities

  • Custom tool execution
  • API integration
  • Scripting support (Python)
  • Extensible functionality

Example prompts

  • "Run the 'calculate_tax' custom tool with income of 50000 and state as California."
  • "Execute the script located at /path/to/my/script.py using the custom tool skill."
  • "Use the custom tool to call the external API endpoint https://example.com/api/data, passing parameters: { 'key': 'value' }."

Tips & gotchas

  • Ensure the necessary dependencies (e.g., Python interpreter) are installed and configured correctly for script execution.
  • Carefully define the input parameters and expected output format for custom tools to ensure accurate results.
