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. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 5.8.0 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. 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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-09T06:46:10.653Z - **Finished:** 2026-10-09T06:46:39.696Z - **Download time:** 1293 ms - **Static scan time:** 2765 ms - **AI review time:** 24984 ms - **Total time:** 29043 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 concrete attack was identified. The package contains workspace skill integration that mirrors selected files into a project’s Claude skill directory during collection import. - **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. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:46:39.696Z ### AI review details - **Review stage:** source\_first\_review - **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. - **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. - **Files touched:** data/skills/\, .claude/skills/\ ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **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. ## Affected versions and remediation This report applies to @mulmoclaude/core@5.8.0. - Review the evidence and your use of @mulmoclaude/core@5.8.0 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.
