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 facebook/react at d083ec1da1.

    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 verify skill allows AI agents to validate data, inputs, or outputs against predefined criteria. It ensures accuracy and reliability by checking for consistency, correctness, and adherence to rules or constraints.

When to use it

  • Before processing user input to ensure it meets expected formats or ranges.
  • After generating content to confirm it aligns with specified guidelines or facts.
  • During data integration workflows to validate the integrity of incoming information.
  • To check if a system's output matches expected results in testing scenarios.

Key capabilities

  • Data validation against schema or rules
  • Input sanitization and format checking
  • Output verification for accuracy and consistency

Example prompts

  • "Verify that this email address is valid."
  • "Check if the user input follows the required JSON structure."
  • "Ensure the generated response matches the provided facts."

Tips & gotchas

  • Define clear validation rules upfront to avoid ambiguity.
  • Be mindful of edge cases, as some inputs may not fit neatly into predefined criteria.
