Hum: a self-improving coding agent for your terminal.

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The lifecycle hook performs package-aligned setup of Hum's own runtime, and the launcher invokes that runtime. The scanner's browser-credential and remote-bridge hints did not establish credential exfiltration or another attack in the inspected source.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation runs the postinstall setup; normal CLI use starts the launcher.

Impact

The inspected behavior supports the package's stated terminal coding-agent function; no concrete malicious behavior was established.

Mechanism

Setup installs a Python core and stages a matching package release in Hum's own version directory. The launcher chooses that entrypoint.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json declares a postinstall hook for the package's setup script.
The installer places the matching Hum package and Python core under the package's own ~/.hum version directory.
The launcher selects that installed entrypoint, and the CLI's default service endpoint is hum.metaphi.ai.
