Hum: a self-improving coding agent for your terminal.
AI Security Review
scanned 12d ago · by lpm-firewall-aiThe package has an automatic postinstall that can execute a downloaded uv installer and install its own Python core. This warrants a warning for first-party package-owned runtime setup, but the inspected source does not establish a concrete attack or block-eligible behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the npm package when the matching Hum core version is absent.
Impact
It installs the package’s core runtime on the consumer’s machine. No broader agent configuration mutation or unrelated dependency approval change was identified in the inspected installer.
Mechanism
The postinstall calls installCore; it may fetch and execute uv’s shell installer, create a Python environment, and install hum-cli at the package version.
AI rationale
The package has an automatic postinstall that can execute a downloaded uv installer and install its own Python core. This warrants a warning for first-party package-owned runtime setup, but the inspected source does not establish a concrete attack or block-eligible behavior.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs a postinstall hook that calls installCore when its version is not already installed.
- The hook can install uv through a shell command that pipes a remote installer into execution.
- The installer creates a Python environment and installs the matching hum-cli version.
Evidence against
- The setup installs the package’s own core into the user’s Hum directory and checks whether that version is already present.
- The inspected installer shows no consumer dependency approval changes or broad agent configuration writes.
