Hum: a self-improving coding agent for your terminal.
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall performs conditional setup for the package’s own core, but it may execute a remote installer through a shell pipeline. That warrants a warning for the automatic remote-code installation surface; the inspected source does not establish a concrete attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the npm package when the requested Hum core version is not already installed and uv is unavailable.
Impact
The installer can execute code obtained from astral.sh and add Hum’s core to the user’s local Hum installation.
Mechanism
The installer invokes a shell or PowerShell command to fetch and execute the uv installer, then uses uv to create an environment and install the Hum core.
AI rationale
The postinstall performs conditional setup for the package’s own core, but it may execute a remote installer through a shell pipeline. That warrants a warning for the automatic remote-code installation surface; the inspected source does not establish a concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json registers a postinstall script that runs scripts/postinstall.js.
- The postinstall handler calls installCore when the requested core version is not installed.
- installCore runs a shell or PowerShell command that pipes a script from astral.sh directly to a shell when uv is absent.
- The installer creates a Python environment and installs the Hum core into a versioned directory under the user’s Hum home.
Evidence against
- The installer targets Hum’s own core and versioned package directories; the inspected code does not show mutation of a foreign or broad AI-agent control surface.
- The evidence shows no credential harvesting, unrelated data exfiltration, or destructive behavior.
