@jait/gateway@0.1.830

Jait AI gateway — local-first AI coding agent with terminal, filesystem, and browser control

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has a concrete automatic install hook that downloads and installs executable third-party code outside npm. The inspected source does not establish credential theft, self-dependency chaining, or broad agent-control-surface mutation, so a warning is more proportionate than a block.

Static reason

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

Trigger

npm installation, through the postinstall hook.

Impact

It expands the install-time supply-chain trust boundary and writes a managed runtime under the user's home directory.

Mechanism

Automatic pip-based runtime installation.

AI rationale

Evidence

package.jsonbin/install-runtime.mjsdist/services/code-graph/graphify-runtime.js~/.jait/runtime/graphify/venv~/.jait/runtime/graphify/runtime.json

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Installation automatically runs a runtime provisioner.
The provisioner creates a home-directory virtual environment and runs pip to download and install graphifyy.
This adds an unreviewed secondary package execution path during npm installation.

Evidence against

No runtime dependency on @jait/gateway itself is declared.
The inspected browser network code uses configured API keys for named provider requests; it does not show secret harvesting.
