AI Security Review
scanned 5d ago · by lpm-firewall-aiThe manifest shows no automatic install hook, but obfuscation prevents resolving the skill installer’s callers and activation. Manual review is needed to determine whether agent skill changes require user action.
Static reason
One or more suspicious static signals were detected.
Trigger
The installer’s activation and caller could not be determined from the reviewed obfuscated bundle.
Impact
Agent skill configuration may be changed; whether this is user-invoked or automatic remains unresolved.
Mechanism
The bundle resolves platform, project, or managed skill directories and writes supplied skill files there.
AI rationale
The manifest shows no automatic install hook, but obfuscation prevents resolving the skill installer’s callers and activation. Manual review is needed to determine whether agent skill changes require user action.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Manual Review at 68.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The package CLI entrypoint begins with heavily obfuscated decoder code.
- The MCP bundle resolves skill directories for agent platforms and writes supplied skill files there; the reviewed excerpts do not establish when that installer is called.
Evidence against
- The manifest lists prepublishOnly running build.mjs, with no preinstall, install, or postinstall hook.
