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 latestaiagents/agent-skills at 6120c5539d.

    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 analyze and assess JSON Web Token (JWT) security. It can identify common vulnerabilities like weak algorithms, expired tokens, and potential injection flaws within JWT structures. The agent can also provide recommendations for strengthening JWT implementation based on best practices.

When to use it

  • Auditing existing systems: Evaluate the security posture of applications using JWT authentication.
  • Code review assistance: Help developers identify potential JWT-related vulnerabilities during code reviews.
  • Security training: Demonstrate common JWT attack vectors and mitigation strategies.
  • Automated vulnerability scanning: Integrate into CI/CD pipelines to automatically check for JWT issues.

Key capabilities

  • JWT validation
  • Algorithm analysis
  • Expiration date checking
  • Vulnerability identification

Example prompts

  • "Analyze this JWT: [paste JWT here] and tell me if there are any security concerns."
  • "What are the potential risks associated with using the 'alg' parameter set to 'HS256' in a JWT?"
  • "Review this code snippet for proper JWT handling: [paste code here]"

Tips & gotchas

The agent requires a valid JWT string or code related to JWT implementation as input. The accuracy of the analysis depends on the completeness and correctness of the provided information.
