Core runtime for Whalent Agent
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe source shows a real agent skill installation capability that writes platform-provided files into selected agent scopes. Since no concrete attack or lifecycle abuse was established, this warrants a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.
Trigger
A user or agent invokes the skill installation operation with a selected scope and skill.
Impact
Installed skill content can affect later agent behavior; no malicious content or unconsented configuration change was established.
Mechanism
The CLI retrieves skill files from the configured platform and writes them under the chosen machine, workspace, or agent skill directory.
AI rationale
The source shows a real agent skill installation capability that writes platform-provided files into selected agent scopes. Since no concrete attack or lifecycle abuse was established, this warrants a warning rather than a publish block.
Evidence
dist/index.cjsdist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest points the package’s CLI entrypoint to dist/index.cjs and declares no npm lifecycle hooks.
- The skill integration selects platform agent directories and supports machine, workspace, and agent scopes.
- The bundled skill helper downloads files from the configured platform and writes them into the selected skill directory.
- The CLI handler inspected in dist/index.cjs connects the download and installation steps to a requested skill operation.
Evidence against
- No source evidence established an install-time trigger or an unrelated credential recipient.
- The inspected behavior is a skill-management feature; no malicious payload or unconsented agent configuration change was established.
