AI Security Review

scanned 14d ago · by lpm-firewall-ai

The package automatically installs its own agent extension during postinstall, so the agent extension lifecycle policy calls for a warning. The inspected installer uses ownership checks, and no concrete attack behavior was established.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package with npm runs its postinstall hook.

Impact

The extension is loaded as an agent integration after installation, without a separate consent step shown in the inspected install path.

Mechanism

The hook copies the bundled extension to the Pi agent extensions directory; the extension invokes the agency command and can alter the agent’s system prompt.

AI rationale

Evidence

package.jsonscripts/install-pi-extension.tspi-extensions/agency.ts

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs the package’s extension installer automatically.
The installer copies the package-owned extension into the user’s Pi agent extensions directory and updates files it can verify it owns.
The extension is an agent integration that invokes the agency command and modifies the agent’s system prompt.
The integration service also defines project-local agent and OpenCode configuration paths.

Evidence against

The installer skips an existing extension unless it can verify ownership, and only removes the extension during preuninstall when its contents match the ownership record.
The inspected integration and extension code shows no credential collection or network exfiltration.
