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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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 automatically discover, scan, and validate the security posture of application programming interfaces (APIs). It identifies vulnerabilities such as injection flaws, broken authentication, and insecure data handling within API endpoints.

When to use it

  • During the development lifecycle to catch API vulnerabilities before they reach production environments.
  • When auditing third-party integrations or legacy systems for compliance with security standards.
  • To continuously monitor APIs for new threats after a recent code deployment or infrastructure change.
  • As part of a broader DevSecOps pipeline to automate security testing alongside functional tests.

Key capabilities

  • Automated discovery of API endpoints and their associated routes.
  • Execution of vulnerability scans targeting common OWASP Top 10 issues.
  • Validation of authentication mechanisms and authorization controls.
  • Reporting of specific security findings with severity ratings.

Example prompts

  • "Run a full security scan on our public REST API to identify any injection vulnerabilities."
  • "Test the authentication flow of this GraphQL endpoint for credential leakage or broken access control."
  • "Analyze these API logs and endpoints to detect insecure data transmission patterns."

Tips & gotchas

Ensure you have explicit authorization to test the target APIs, as unauthorized scanning can be illegal. Always configure the skill to operate in a non-destructive mode to prevent accidental disruption of live services during testing.
