@mulmoclaude/core@5.11.1
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 supports a warning for explicit user-command mutation of an AI-agent configuration surface: registry imports may mirror skill files into .claude/skills. No malicious behavior or unconsented install-hook activation was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
An application or user invokes the collection registry import operation with mirroring enabled.
Impact
Imported content becomes available in the project’s Claude skill directory; inspected source does not establish a malicious payload or automatic npm-install activation.
Mechanism
The importer mirrors allowlisted skill content from the project staging directory into .claude/skills.
AI rationale
The source supports a warning for explicit user-command mutation of an AI-agent configuration surface: registry imports may mirror skill files into .claude/skills. No malicious behavior or unconsented install-hook activation was established.
Evidence
dist/collection/registry/server/index.jsdist/skill-bridge/index.jsdata/skills/<slug>.claude/skills/<slug>
Decision evidence
public snapshotAI called this Suspicious at 81.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json contains build, typecheck, test, and lint scripts; no install lifecycle script is shown.
- The collection registry importer can mirror imported skill files into the project’s .claude/skills directory when its mirror option is enabled.
- The bridge writes allowlisted files from data/skills/<slug> into .claude/skills/<slug>.
- The registry source describes the mirror as an explicit import installation path; no npm lifecycle trigger for it was found.
Evidence against
- The package manifest and registry module source show ordinary module entrypoints and explicit registry functionality; the inspected excerpts do not establish malicious behavior.
- The two server variants and the discovery, prompt-safety, and Google files were inspected at their indicated locations; those excerpts do not establish an attack.
