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 igbuend/grimbard at cde088f5d7.

    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 identifies and explains common OAuth security anti-patterns. It helps users understand vulnerabilities that arise from misconfigured or improperly implemented OAuth flows, such as exposed client secrets, improper redirect URI validation, and insufficient scope enforcement. The skill provides explanations of these patterns and suggests remediation strategies to improve overall application security.

When to use it

  • Security Audits: During code reviews or penetration testing to identify potential OAuth vulnerabilities.
  • Design Reviews: To ensure secure OAuth integration during the design phase of new applications.
  • Incident Response: To analyze security incidents involving OAuth and determine root causes.
  • Developer Training: As a learning tool for developers unfamiliar with OAuth best practices.

Key capabilities

  • Identification of common OAuth anti-patterns.
  • Explanation of the risks associated with each anti-pattern.
  • Recommendations for remediation strategies.

Example prompts

  • "What are some common OAuth security vulnerabilities?"
  • "Explain the risk of exposed client secrets in an OAuth flow."
  • "How can I prevent redirect URI manipulation attacks in my application?"

Tips & gotchas

This skill assumes a basic understanding of OAuth concepts. It's most effective when used to review existing implementations or designs, rather than as a standalone guide for building OAuth integrations from scratch.
