@mulmoclaude/core@5.8.1
Shared server-side core for MulmoClaude and MulmoTerminal — the always-shipped-together subsystems consolidated behind subpath exports so the two hosts can't drift. Server-only except the browser-safe ./artifacts, ./whisper/client, ./workspace-setup/slug,
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe package has no npm install lifecycle hook, but its registry import feature can add fetched skill instructions to the active Claude skills directory. This is a user-invoked agent extension capability, so warn without blocking publication.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A host invokes the registry import operation for a selected collection.
Impact
Imported skill content can become active agent instructions in that workspace.
Mechanism
The importer stores the collection in the workspace and mirrors allowlisted skill and schema files into .claude/skills.
AI rationale
The package has no npm install lifecycle hook, but its registry import feature can add fetched skill instructions to the active Claude skills directory. This is a user-invoked agent extension capability, so warn without blocking publication.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json defines build, typecheck, test, and lint scripts, with no install lifecycle hook.
- The registry exposes import as a host-facing POST operation; importing fetches a registry bundle and writes it into the workspace.
- After import, the code mirrors allowlisted skill files into the active .claude/skills tree; the bridge writes those files to their canonical paths.
- The package describes itself as shared MulmoClaude and MulmoTerminal core, and the bridge limits mirrored paths to skill and schema files or safe action templates.
Evidence against
- The inspected behavior is activated through a registry import operation, not an npm install hook.
- The mirror is limited to allowlisted files and operates within the workspace’s skill directories.
