AI Security Review

scanned 13d ago · by lpm-firewall-ai

The automatic install-time execution of an opaque binary for skill refresh leaves a concrete but unresolved first-party extension setup risk. The inspected JavaScript does not establish harmful side effects, so this warrants a warning rather than a block.

Static reason

One or more suspicious static signals were detected.

Trigger

npm installation runs the postinstall hook.

Impact

The opaque binary may perform skill setup during installation; its effects cannot be confirmed from the inspected source.

Mechanism

The hook downloads the platform binary, checks its SHA-256 against the manifest, installs it, and invokes it with +connect --refresh.

Decision evidence

public snapshot

AI called this Suspicious at 75.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js automatically after installation.
The postinstall downloads a platform binary and then runs it with +connect --refresh; the binary’s behavior is not present in the inspected JavaScript source.
The download code checks the binary against the manifest’s SHA-256 digest, and the manifest identifies a BytePlus CDN source.

Evidence against

scripts/run.js launches the platform-specific binary with the CLI arguments supplied by the user.
The inspected source shows no consumer dependency-approval changes, credential collection, or unrelated agent configuration writes.
