@mulmoclaude/core@4.10.0
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 package contains an explicit collection-import path that mirrors skill content into `.claude/skills`, creating a guarded agent capability. No automatic install-time mutation or separate malicious behavior was established, so this warrants a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A caller invokes the collection import operation.
Impact
Imported skill content becomes available to Claude CLI in that workspace; no credential theft, stealth, or destructive attack was established.
Mechanism
The registry writes the imported collection and mirrors its allowlisted files from `data/skills` into `.claude/skills`.
AI rationale
The package contains an explicit collection-import path that mirrors skill content into `.claude/skills`, creating a guarded agent capability. No automatic install-time mutation or separate malicious behavior was established, so this warrants a warning rather than a publish block.
Evidence
dist/collection/registry/server/index.jsdist/skill-bridge/index.jsdata/skills/<slug>.claude/skills/<slug>
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Registry imports write validated collection skill files into the workspace’s `.claude/skills` directory.
- The registry mirrors allowlisted files during an explicit collection import; no npm install lifecycle hook was found.
- The skill bridge writes files from the workspace staging directory into the matching active skill directory.
Evidence against
- The package scripts shown are build, typecheck, test, and lint; none is an install hook.
- The manifest maps the registry server through package exports, and inspection found no automatic install-time activation of the mirroring code.
