@mulmoclaude/core@5.11.3
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 11d ago · by lpm-firewall-aiThe package has a guarded runtime capability that installs skill content into Claude’s workspace extension directory, so a warning is appropriate. The inspected behavior does not establish malicious activity or an install-hook attack.
Static reason
One or more suspicious static signals were detected.
Trigger
A runtime registry import in a workspace with a staging tree, or schema authoring for a staged skill.
Impact
Imported or authored skill content becomes available to Claude as an active skill.
Mechanism
The registry mirrors allowlisted bundle files from staging into `.claude/skills`; schema authoring also calls the mirror helper.
AI rationale
The package has a guarded runtime capability that installs skill content into Claude’s workspace extension directory, so a warning is appropriate. The inspected behavior does not establish malicious activity or an install-hook attack.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Registry imports mirror selected bundle files into the workspace’s `.claude/skills` directory when a staging tree exists.
- The bridge copies staged skill content into the active Claude skill directory; schema authoring also invokes the mirror.
- The registry import function is runtime-invoked; package scripts shown are build, typecheck, test, and lint.
Evidence against
- The mirror is disabled when no staging tree exists, and the importer mirrors only files selected by its allowlist.
- No install-time mutation or confirmed credential transfer was identified in the inspected paths.

Copied Package Dependency Bridge
Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.
