AI Security Review
scanned 13d ago · by lpm-firewall-aiThe source shows automatic, package-owned skill setup through an opaque binary, which leaves a real but unconfirmed extension lifecycle risk. The binary download is digest-checked and uses vendor-associated sources; no concrete attack behavior is established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package runs its postinstall hook.
Impact
The binary may add or update skills during installation; the specific targets and effects are not visible in inspected JavaScript source.
Mechanism
The hook retrieves a binary and invokes it with +connect --refresh; the manifest also points to a skills archive.
AI rationale
The source shows automatic, package-owned skill setup through an opaque binary, which leaves a real but unconfirmed extension lifecycle risk. The binary download is digest-checked and uses vendor-associated sources; no concrete attack behavior is established.

Decision evidence
public snapshotAI called this Suspicious at 79.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs scripts/postinstall.js during installation.
- The install hook downloads and executes a platform binary, then automatically invokes its skill-sync command.
- The skill archive is hosted on the vendor CDN and includes a SHA-256 digest; the downloaded binary is checked against its expected digest.
- The JavaScript source does not show what the binary’s skill-sync operation changes.
Evidence against
- The GitHub fallback URL is restricted to byteplus-sdk/ark-cli release assets.
- The binary download is rejected if its SHA-256 differs from the manifest value.
