Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 22 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 5.12.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected Google and skill bridge excerpts support ordinary package behavior, and the manifest has no install hook. Static analysis reports unresolved parse and trigger coverage gaps, so the full package cannot be cleared from the available source review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 68.0% - **Started:** 2026-10-19T01:39:57.434Z - **Finished:** 2026-10-19T01:41:44.139Z - **Download time:** 3832 ms - **Static scan time:** 2745 ms - **AI review time:** 100128 ms - **Total time:** 106705 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:** No confirmed attack surface was identified in the inspected excerpts, but the package review remains unresolved because static analysis reports incomplete source coverage. - **Trigger:** No malicious trigger was confirmed in the inspected source. - **Impact:** The inspected behavior does not establish an attack; incomplete analysis prevents a clean determination. - **Review source:** ai\_review - **Reviewed:** 2026-10-19T01:41:44.139Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The reviewed Google excerpts concern calendar sync state, and the reviewed skill excerpts concern project skill handling. - **Rationale:** The inspected Google and skill bridge excerpts support ordinary package behavior, and the manifest has no install hook. Static analysis reports unresolved parse and trigger coverage gaps, so the full package cannot be cleared from the available source review. ### Review decision - **Verdict:** Manual Review - **Confidence:** 68.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest lists build, typecheck, test, and lint scripts and no install lifecycle hook., The inspected Google code stores calendar sync tokens and shadow event state under workspace calendar data paths., The inspected skill bridge uses project skill directories and validates skill slugs; the cited registry and server locations describe reading and importing those project skills., Static analysis reports parse errors in promptSafety-CKmqbSTK.cjs and an incomplete manifest trigger analysis, leaving package behavior unresolved. - **Evidence against:** The inspected excerpts do not establish credential transfer, an unrequested account action, or install-time mutation of an agent control surface. ## Affected versions and remediation This report applies to @mulmoclaude/core@5.12.0. - Review the evidence and your use of @mulmoclaude/core@5.12.0 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.
