Jwt Toolkit

Security checks across malware telemetry and agentic risk

Overview

This is a local JWT inspection tool that does not show hidden network access, persistence, or unrelated file access, but users should treat any real JWT as sensitive.

Install only if you need local JWT inspection. Avoid pasting live tokens into shared terminals, logs, shell history, or support chats; prefer disposable or redacted examples when possible. Do not rely on this tool alone to prove a token is trustworthy, because it decodes and checks expiry but does not verify signatures, issuer, audience, or keys.

Missing User Warnings

Medium

Confidence: 84% confidence
Finding: The skill explicitly encourages reading JWTs from files, stdin, and curl pipelines without warning that JWTs often contain sensitive authentication and identity data. Users may paste live access tokens into shells, logs, history, or shared environments, leading to inadvertent credential disclosure or misuse.
