@mulmoclaude/core@5.0.1
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 14d ago · by lpm-firewall-aiThe source confirms a constrained skill-file bridge, but no npm lifecycle hook or concrete malicious behavior. The flagged configuration writes are limited to registry skill import behavior, so the static signals do not establish an attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A registry import path invokes the mirroring helper.
Impact
This can place behavior-bearing skill content where Claude CLI discovers it, but the inspected code shows constrained mirroring and no confirmed attack behavior.
Mechanism
The helper copies staged skill content into .claude/skills after filtering paths to named skill files and safe action templates.
AI rationale
The source confirms a constrained skill-file bridge, but no npm lifecycle hook or concrete malicious behavior. The flagged configuration writes are limited to registry skill import behavior, so the static signals do not establish an attack.
Evidence
dist/collection/registry/server/index.jsdist/skill-bridge/index.js
Decision evidence
public snapshotAI called this Clean at 83.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The package exposes build and development scripts, with no preinstall, install, or postinstall hook in the inspected script block.
- Registry import code mirrors selected skill files into the workspace’s .claude/skills directory.
- The bridge limits mirrored files to SKILL.md, schema.json, and safe action templates.
- The bridge resolves files beneath data/skills and rejects paths outside that staging directory or outside its allowlist.
Evidence against
- No inspected source shows an npm lifecycle trigger or a concrete attack chain.
