@whalent/agent@0.3.484
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 22d ago · by lpm-firewall-aiThe inspected source supports a warning for invoked agent instruction mutation, rather than a malware block. No automatic npm lifecycle attack was identified.
Static reason
One or more suspicious static signals were detected.
Trigger
Invocation of the core skill management tool with an installation or removal operation.
Impact
Invoked operations can change instructions available to subsequent agent sessions.
Mechanism
The handler downloads skill files, resolves an agent, workspace, or home directory scope, and writes or removes the selected skill directory.
AI rationale
The inspected source supports a warning for invoked agent instruction mutation, rather than a malware block. No automatic npm lifecycle attack was identified.
Evidence
dist/core.cjsdist/mcp.cjs.claude.agents
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The core tool handler downloads skill content and invokes installation or removal with a requested scope.
- The skill directory resolver supports agent instruction directories under the user home or workspace, including .claude and .agents.
- The installer creates the selected directory and writes supplied skill files.
Evidence against
- package.json has no preinstall, install, or postinstall hook and no runtime self-dependency.
- The inspected mutation requires a tool operation; no covert installation attack or credential theft was established.
