Core runtime for Whalent Agent
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe package has no lifecycle scripts, and the cited agent-directory behavior is consistent with skill setup. The inspected source does not establish an active attack or an unresolved dangerous capability.
Static reason
One or more suspicious static signals were detected.
Trigger
A skill installation operation invokes the installation helper.
Impact
Skill files may be added to an agent directory as part of setup; no malicious impact is established by the inspected source.
Mechanism
The helper creates the resolved skill directory and writes downloaded skill files; the inspected excerpts do not show an npm install hook or an unconsented broad configuration change.
AI rationale
The package has no lifecycle scripts, and the cited agent-directory behavior is consistent with skill setup. The inspected source does not establish an active attack or an unresolved dangerous capability.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Clean at 78.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines the package entrypoints and dependencies but no install lifecycle hooks.
- dist/mcp.cjs maps skill destinations to platform-specific home directories and exposes a skill installation helper that creates directories and writes files.
- Skill files are downloaded from a supplied server base URL with an Authorization header; this supports agent skill setup, but the inspected code does not establish an unrestricted credential-forwarding attack.
