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 jeremylongshore/claude-code-plugins-plus-skills at a7be181f58.

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

About this skill

What it does

This skill enables AI agents to securely authenticate users against APIs. It handles the complexities of API authentication flows, allowing agents to verify user credentials and access protected resources on behalf of those users. The skill facilitates secure interactions with external services without exposing sensitive information directly to the agent or user.

When to use it

  • Automated data retrieval: Retrieve data from a customer relationship management (CRM) system after verifying the user's identity.
  • Secure API calls: Execute actions on behalf of a user, such as updating their profile in a third-party application, while ensuring proper authentication and authorization.
  • Backend integration: Integrate AI agents with existing backend systems that require secure authentication mechanisms like OAuth or JWT.
  • Workflow automation: Automate tasks involving API interactions where user authentication is a prerequisite.

Key capabilities

  • API Authentication
  • User Verification
  • Secure Resource Access

Example prompts

  • "Authenticate this user with the CRM using their email and password."
  • "Get the current user's profile from the external service, ensuring proper authentication."
  • "Update the user’s address in the system after verifying their identity via API."

Tips & gotchas

This skill requires appropriate API credentials (client ID, client secret, etc.) to be configured. Ensure these credentials are securely stored and managed to prevent unauthorized access.
