@whalent/agent@0.3.496
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 16d ago · by lpm-firewall-aiThe obfuscated bundle exposes agent skill file installation, but the inspected source does not establish an automatic trigger or a malicious chain. Treat this as a warning for agent capability risk rather than a confirmed attack.
Static reason
One or more suspicious static signals were detected.
Trigger
The skill installation routine is invoked.
Impact
The capability can add agent skills; the inspected excerpts do not establish whether consent gates its invocation.
Mechanism
It creates the resolved skill directory and writes skill files after checking their paths.
AI rationale
The obfuscated bundle exposes agent skill file installation, but the inspected source does not establish an automatic trigger or a malicious chain. Treat this as a warning for agent capability risk rather than a confirmed attack.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 74.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package uses obfuscated bundled code, which limits tracing its behavior.
- The MCP bundle has a skill installation routine that creates a destination directory and writes skill files.
- The manifest has a prepublishOnly build hook, but no install lifecycle hook.
Evidence against
- The skill installation routine is not shown to run during npm installation.
- The inspected write routine uses a safe-path check before writing skill files.
