Automated safety checks

scanned 2 Oct 2026

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 g1joshi/agent-skills at 6a74cf03a8.
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 allows AI agents to work with JSON Web Tokens (JWTs). It can decode, verify, and generate JWTs, enabling secure authentication and authorization workflows. The agent can extract information from the payload of a JWT or create new tokens based on provided data.

When to use it

Verifying User Authentication: Confirm if a user's token is valid before granting access to protected resources.
Decoding Token Information: Extract user roles, permissions, or other claims embedded within a JWT payload.
Generating Access Tokens: Create new JWTs for users after successful login or registration processes.
Automating API Authentication: Use the skill to automatically handle authentication with APIs that require JWTs.

Key capabilities

JWT Decoding
JWT Verification
JWT Generation

Example prompts

"Decode this JWT: [JWT Token]"
"Verify if this JWT is valid: [JWT Token]"
"Generate a JWT for user 'john.doe' with role 'admin'."

Tips & gotchas

The skill requires knowledge of JWT structure and signing algorithms to use effectively. Ensure the agent has access to the necessary secret keys or public certificates for verification and generation.
