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

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The lifecycle behavior is package-aligned setup of a version-matched engine in a dedicated directory, with cleanup limited to the package's earlier launcher shims. The scanner's credential and shell indicators do not establish credential collection or a malicious execution chain in the inspected source.

Static reason

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

Trigger

The npm postinstall hook runs during installation; the CLI engine starts when the user invokes hum.

Impact

No credential collection, unrelated data transfer, or broad control-surface mutation was established from the inspected behavior.

Mechanism

The hook bootstraps uv if needed, creates a Python environment in HUM_HOME or ~/.hum, and installs the matching hum-cli release. The npm CLI update check reports an update command without starting a background update.

Decision evidence

public snapshot

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

Evidence for AI clean decision

The npm postinstall creates an isolated Python engine under HUM_HOME or ~/.hum and installs the matching hum-cli version.
The CLI starts that engine when the user invokes hum; npm-layout update checks show an update command rather than starting a background installer.
The installer removes an earlier hum-cli tool installation and its own launcher shims when present.

Evidence against

The postinstall can bootstrap uv through a shell command and fetch the matching engine package, so installation performs network-backed setup.
The bundle contains an update endpoint, but its update flow does not automatically install updates for npm-layout installations.
