@whalent/agent@0.3.516
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package provides a concrete skill installation capability that can write into agent skill directories, while the inspected code does not resolve its caller or consent flow. The manifest shows no preinstall, install, or postinstall hook, so the available evidence supports a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
A caller invokes the skill installation capability.
Impact
Installed skill files may add behavior to an agent environment or workspace. No automatic install-time activation was established.
Mechanism
The code resolves a scope-specific skill directory, creates it, and writes skill files; a related helper fetches files from a configured server endpoint.
AI rationale
The package provides a concrete skill installation capability that can write into agent skill directories, while the inspected code does not resolve its caller or consent flow. The manifest shows no preinstall, install, or postinstall hook, so the available evidence supports a warning rather than a block.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 75.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- dist/mcp.cjs resolves skill directories for agent, workspace, and machine scopes, including paths under the user home directory.
- dist/mcp.cjs can create a skill directory and write skill files into it.
- dist/mcp.cjs downloads skill files from a configured server endpoint using a bearer token.
- package.json has no preinstall, install, or postinstall hook; prepublishOnly runs the build.
Evidence against
- The inspected manifest shows prepublishOnly is a build command, not an install-time agent configuration change.
