@mulmoclaude/core@4.0.1
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 runtime AI-agent control-surface write capability, warranting a warning. Source inspection shows it is host-triggered and constrained rather than malicious install-time behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Host-driven collection import or schema update with mirroring enabled.
Impact
Project AI-agent skill instructions may be added, updated, or removed.
Mechanism
Allowlisted staged skill-file mirroring
AI rationale
The package has a real runtime AI-agent control-surface write capability, warranting a warning. Source inspection shows it is host-triggered and constrained rather than malicious install-time behavior.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Runtime skill bridge copies staged content into a workspace .claude/skills tree.
- Collection import conditionally mirrors imported bundles into .claude/skills.
- This can alter project AI-agent instructions, but only through exported runtime host functionality.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Bridge restricts slugs and allowlisted files before copying.
- No hidden exfiltration or remote payload execution was found; network URLs serve declared OAuth/registry features.
