Security audit

Bump Doctor

Security checks across malware telemetry and agentic risk

Overview

This skill is a dependency-upgrade helper that fetches public package and GitHub release information, and its network/token behavior is disclosed and aligned with that purpose.

Installers should expect this skill to contact public package registries and GitHub when used. If a GITHUB_TOKEN is present in the environment, the analyzer may use it for GitHub rate limits, so use a minimally scoped token or unset it if that is not desired.

Finding
The skill explicitly instructs the agent to run a Python analyzer that fetches data from npm, PyPI, and GitHub and may read a GITHUB_TOKEN from the environment, yet the skill declares no corresponding permissions. This creates a capability/permission mismatch that can cause unreviewed network access and exposure of environment-derived secrets in an execution context that appears more constrained than it really is.
