Core runtime for Whalent Agent
AI Security Review
scanned 7d ago · by lpm-firewall-aiThe package has no install hook, and the inspected skill setup is an explicit runtime capability. Because it can place fetched content in agent skill directories, residual agent extension setup risk warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
An agent runtime invokes the skill installation operation.
Impact
Installed skill content can affect the instructions available to the selected agent; no automatic attack was established.
Mechanism
The package fetches files for a supplied skill identifier, then creates a machine, workspace, or agent skill directory and writes those files there.
AI rationale
The package has no install hook, and the inspected skill setup is an explicit runtime capability. Because it can place fetched content in agent skill directories, residual agent extension setup risk warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest declares the runtime entry point and no install lifecycle hook.
- The MCP source maps agent skills to platform directories and supports machine, workspace, and agent scopes.
- The installer creates the selected skill directory and writes supplied files there.
- The skill downloader requests files from the Whalent service using an authorization header.
Evidence against
- The observed skill setup is an explicit runtime operation, not an npm install hook.
- The inspected source establishes no credential theft, destructive action, or remote code execution.
