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 sanctifiedops/solana-skills at 3f7d58d383.

    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 provides foundational knowledge of frontend security best practices. It covers common vulnerabilities and mitigation techniques to protect web applications from attacks like Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). The skill aims to improve the overall security posture of user interfaces by identifying and addressing potential risks.

When to use it

  • Code Reviews: Assess frontend code for common vulnerabilities before deployment.
  • Security Audits: Identify weaknesses in existing web applications.
  • Developer Training: Educate developers on secure coding practices.
  • Risk Assessments: Evaluate the potential impact of frontend security flaws.

Key capabilities

  • XSS vulnerability identification and prevention
  • CSRF mitigation techniques
  • Understanding of common attack vectors
  • Secure coding best practices for frontends

Example prompts

  • "Explain how to prevent XSS attacks in a React application."
  • "What are the key differences between CSRF and XSS?"
  • "Give me some secure coding examples for handling user input on a web form."

Tips & gotchas

This skill assumes basic familiarity with frontend development concepts. While it provides foundational knowledge, deeper expertise in specific frameworks or technologies may be required for full implementation of security measures.
