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 secondsky/claude-skills at 8837836131.

    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

This skill enables AI agents to securely authenticate with APIs using credentials provided in environment variables. It handles the necessary headers and token management to access protected endpoints on behalf of the agent.

When to use it

  • Connecting to private dashboards or internal tools that require login tokens.
  • Accessing third-party services like GitHub, Stripe, or Slack bots where API keys are stored securely.
  • Automating workflows that need read/write permissions to external data sources.
  • Ensuring sensitive credentials never appear in chat logs or agent prompts.

Key capabilities

  • Reads authentication tokens from environment variables (e.g., API_KEY, AUTH_TOKEN).
  • Automatically injects required headers into API requests.
  • Supports standard HTTP authentication methods like Bearer tokens and Basic Auth.
  • Integrates seamlessly with the SecondSky AI agent framework.

Example prompts

"Use my GitHub API credentials to check if I have any open pull requests." "Authenticate with my Slack workspace using the stored token and post a summary of today's tasks." "Access my Stripe dashboard via API to retrieve this month's transaction history."

Tips & gotchas

  • Ensure your environment variables are set correctly before invoking the skill; missing keys will cause authentication failures.
  • This skill does not store credentials internally—it relies entirely on the agent’s secure environment configuration, so verify that your secrets manager or local env file is properly secured.
