Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 8 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: bootstrap.pypa.io, deb.nodesource.com, dlcdn.apache.org, get.pnpm.io, go.dev….

    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.

About this skill

What it does

The check-tools skill allows an AI agent to verify if a given tool exists and is accessible. It can confirm the presence of tools based on their names or descriptions, ensuring that subsequent actions utilizing those tools are feasible. This capability helps prevent errors caused by unavailable or misconfigured tools within the agent's environment.

When to use it

  • Validating Tool Availability: Before attempting a complex task requiring specific tools, confirm they are present and functional.
  • Troubleshooting Errors: If an action fails due to a missing tool, use this skill to diagnose the problem.
  • Dynamic Environment Adaptation: When dealing with environments where tools might be added or removed, regularly check for their existence.
  • Tool Selection Guidance: Use it to determine which tools are suitable for a given task based on available options.

Key capabilities

  • Tool Existence Verification
  • Tool Description Matching
  • Accessibility Confirmation (implied)

Example prompts

  • "Does the 'email_sender' tool exist?"
  • "Check if there is a tool that can translate languages."
  • "Confirm the availability of a tool for generating images from text descriptions."

Tips & gotchas

The skill relies on accurate tool naming and descriptions within the agent’s environment. Inconsistent or incomplete information may lead to incorrect results.
