Steam Community Inventory

Security checks across malware telemetry and agentic risk

Overview

This skill is a simple Steam inventory helper that uses a user-provided Steam session cookie for Steam requests, with no hidden execution or unrelated data sharing found.

Install only if you are comfortable giving the agent access to a Steam browser session cookie. Treat STEAM_COOKIES like a password: do not share it, log it, commit it, or leave it in persistent shell history, and sign out of Steam or invalidate the session if it may have been exposed.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill instructs users to extract the `steamLoginSecure` session cookie and place it into an environment variable, but it does not warn that this cookie is effectively an authentication token and highly sensitive. In agent or shell-driven workflows, environment variables and command history can be exposed via logs, subprocesses, debugging output, or other skills, which raises the risk of account compromise if the cookie leaks.
