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 aj-geddes/useful-ai-prompts at 3f5182cfd7.

    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 helps secure APIs by implementing best practices such as rate limiting, input validation, authentication enforcement, and encryption of sensitive data. It also identifies common vulnerabilities like SQL injection or insecure endpoints and suggests mitigation strategies.

When to use it

  • You are developing a new API and want to ensure it follows security standards from the start.
  • Your team is auditing an existing API for potential security weaknesses.
  • You need guidance on implementing secure authentication mechanisms such as OAuth 2.0 or JWT.
  • You're preparing for compliance with industry regulations like GDPR or HIPAA.

Key capabilities

  • Detects and mitigates common API vulnerabilities
  • Recommends secure authentication and authorization strategies
  • Enforces input validation and data sanitization
  • Implements rate limiting to prevent abuse
  • Suggests encryption practices for sensitive data

Example prompts

  • "How can I secure my REST API against SQL injection attacks?"
  • "What are the best practices for implementing OAuth 2.0 in a Node.js application?"
  • "Review this API design and identify potential security risks."

Tips & gotchas

  • Ensure your development environment supports the recommended security protocols before implementation.
  • Regularly update dependencies to avoid known vulnerabilities in third-party libraries.
