AI Security Review
scanned 13d ago · by lpm-firewall-aiThe automatic postinstall invocation of agent Skill sync is an unresolved lifecycle risk because the implementation runs in a downloaded binary. The source shows HTTPS and digest checks, but does not establish what agent files the binary changes.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package runs its postinstall hook, unless ARKCLI_SKIP_POSTINSTALL is set to 1.
Impact
Local agent Skill state may be changed during package installation. The exact writes cannot be verified from the JavaScript source because the CLI binary is downloaded at install time.
Mechanism
The hook downloads and verifies a platform binary, then invokes it with +connect --refresh. The package describes +connect as installing bundled Skills into supported local agents.
AI rationale
The automatic postinstall invocation of agent Skill sync is an unresolved lifecycle risk because the implementation runs in a downloaded binary. The source shows HTTPS and digest checks, but does not establish what agent files the binary changes.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall.js automatically after installation.
- The hook downloads a platform binary and runs it with +connect --refresh, which performs Skill sync during installation.
- The README describes +connect as installing bundled Skills into supported local agents, but presents it as a command to run after installing the CLI.
Evidence against
- The download code requires HTTPS and verifies the binary against a SHA-256 value from the bundled manifest.
- The inspected source shows no credential harvesting or unrelated control-surface mutation.
