AI Security Review
scanned 13d ago · by lpm-firewall-aiThe install hook performs first-party skill refresh through a downloaded, digest-checked binary, which warrants a warning for package-owned agent extension setup. The inspected source does not establish an attack, and its download sources are vendor-aligned.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation on a supported platform, unless ARKCLI_SKIP_POSTINSTALL=1 is set.
Impact
The binary may update skill-related state during installation; no concrete malicious behavior was confirmed from the inspected source.
Mechanism
The postinstall hook downloads the binary from the vendor CDN or stable-release fallback, checks its SHA-256 digest, then runs +connect --refresh.
AI rationale
The install hook performs first-party skill refresh through a downloaded, digest-checked binary, which warrants a warning for package-owned agent extension setup. The inspected source does not establish an attack, and its download sources are vendor-aligned.

Decision evidence
public snapshotAI called this Suspicious at 81.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs scripts/postinstall.js automatically during installation.
- The hook downloads a platform binary and checks its SHA-256 digest against manifest.json.
- The hook invokes that binary with +connect --refresh during installation to sync skills.
- The binary is obtained from a vendor CDN, with a GitHub Release fallback for stable versions.
Evidence against
- The hook requires HTTPS, and the GitHub fallback is restricted to the vendor’s release path.
- The hook provides ARKCLI_SKIP_POSTINSTALL=1 to skip its install behavior.
