@mulmoclaude/core@5.8.0
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 manifest has no install lifecycle hook, and the reviewed agent integration is part of a user-invoked workspace collection import flow with a narrow mirror allowlist. The scanner signals did not establish a concrete attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A caller explicitly imports or updates a collection in a workspace.
Impact
The imported skill becomes available to Claude in that workspace; source inspection did not establish malicious behavior.
Mechanism
The registry flow mirrors the skill file, schema, and allowed action templates from the workspace staging directory into that workspace’s `.claude/skills` directory.
AI rationale
The manifest has no install lifecycle hook, and the reviewed agent integration is part of a user-invoked workspace collection import flow with a narrow mirror allowlist. The scanner signals did not establish a concrete attack.
Evidence
data/skills/<slug>.claude/skills/<slug>
Decision evidence
public snapshotAI called this Clean at 82.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines build, typecheck, test, and lint scripts but no install lifecycle hook.
- Registry import places a skill in the workspace and mirrors it into `.claude/skills` when a staging tree exists; this is an explicit collection import flow.
- The bridge limits mirrored files to skill metadata and safe action templates, and confines slugs to a restricted format.
- The inspected server bundles describe workspace collection and skill handling; no concrete attack behavior was established.
- Discovery, prompt-safety, and Google bundle excerpts show module imports, not evidence of a malicious payload.
