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 patricio0312rev/skills at 79ea6af485.

    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 generate and configure Content Security Policy (CSP) headers for web applications. It helps harden websites against cross-site scripting (XSS) attacks by defining strict rules on which resources the browser is allowed to load.

When to use it

  • Deploying new frontend applications that require immediate protection against injection attacks.
  • Auditing existing websites to ensure they have appropriate security headers in place.
  • Automating the configuration of CSP directives during a CI/CD pipeline deployment.
  • Reducing the risk of data theft or malware execution via browser-based exploits.

Key capabilities

  • Generates specific Content Security Policy header strings.
  • Configures allowed sources for scripts, styles, images, and other resources.
  • Helps define strict security boundaries to prevent unauthorized content loading.

Example prompts

  • "Create a Content Security Policy header that only allows scripts from our domain and Google Fonts."
  • "Generate a CSP configuration that blocks inline scripts but permits external JavaScript files from trusted CDNs."
  • "What are the recommended directives for securing a React application against XSS vulnerabilities?"

Tips & gotchas

Ensure you test generated policies in a staging environment before applying them to production, as overly strict rules can break legitimate functionality. Always verify that all necessary resources (like analytics scripts or third-party APIs) are explicitly whitelisted in the policy.
