@mulmoclaude/core@4.1.1
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 2mo ago · by lpm-firewall-aiThe package has a real project-level AI-agent extension write path, including remote collection import, but it is runtime/host-invoked and constrained to workspace-local allowlisted paths. No malicious execution, secret theft, or install-time mutation was found.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Host/user invokes skill mirroring or collection-registry import.
Impact
Imported or staged skill instructions become discoverable by Claude Code in that workspace.
Mechanism
Allowlisted skill-file mirroring into project `.claude/skills`.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Runtime bridge writes allowlisted staged skill files into project `.claude/skills`.
- Registry import fetches collection bundles and can mirror their skill files into `.claude/skills`.
Evidence against
- package.json has no npm lifecycle hook.
- Bridge rejects paths outside `data/skills`, invalid slugs, and non-allowlisted files.
- Active preset sync does not auto-create unstarred skills and checks symlink containment.
- No credential harvesting, covert exfiltration, eval, or shell execution found.
