Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Not malicious: no install hooks or automatic execution were found. Warn because explicit remote content is activated in a Claude skill control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-07-28T11:53:11.621Z - **Finished:** 2026-07-28T11:54:25.113Z - **Download time:** 504 ms - **Static scan time:** 1587 ms - **AI review time:** 71401 ms - **Total time:** 73492 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An explicit registry-import operation downloads collection content and activates selected files as Claude skills. OAuth and Google API functions are user-invoked integration features, not install-time activity. - **Trigger:** Host/user invokes importRegistry or performImport for a collection. - **Impact:** Imported remote instructions can influence Claude behavior in that workspace. - **Evidence paths:** package.json, dist/collection/registry/server/index.js, dist/skill-bridge/index.js, dist/google/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T11:54:25.113Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote skill-bundle import and controlled .claude skill mirroring - **Rationale:** Not malicious: no install hooks or automatic execution were found. Warn because explicit remote content is activated in a Claude skill control surface. - **Files touched:** data/skills/\, data/skills/\/SKILL.md, data/skills/\/schema.json, .claude/skills/\ - **Network endpoints:** https://receptron.github.io/mulmoclaude-collections/index.json, https://raw.githubusercontent.com/receptron/mulmoclaude-collections/main ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/collection/registry/server/index.js imports remote bundles into .claude/skills., dist/skill-bridge/index.js mirrors SKILL.md and templates to active Claude skill paths., Registry defaults fetch from receptron.github.io and raw.githubusercontent.com., dist/google/index.js handles OAuth tokens and Google Calendar/Tasks/Drive APIs. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks., Skill import is an exported performImport/importRegistry operation, not import-time behavior., Skill mirror restricts paths to an allowlist and safe slugs., Google token files are written with mode 0600; broker requires HTTPS., No covert exfiltration, eval, or shell-command execution found. ## Affected versions and remediation This report applies to @mulmoclaude/core@0.25.0. - Review the evidence and your use of @mulmoclaude/core@0.25.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
