Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.29.0 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. No concrete malicious chain was found. The package has an explicit runtime capability to install first-party workspace Claude skills from remote registry content, so it warrants a non-blocking warning under the stated policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-28T11:53:09.724Z - **Finished:** 2026-07-28T11:54:20.020Z - **Download time:** 502 ms - **Static scan time:** 3494 ms - **AI review time:** 66300 ms - **Total time:** 70296 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 collection-import runtime API downloads a registry bundle and installs allowlisted skill files into the current workspace’s Claude skill directory. No install-time execution or unconsented broad agent-config mutation was found. - **Trigger:** Host explicitly calls performImport for a selected collection. - **Impact:** Imported content can become an active Claude workspace skill after deliberate import. - **Evidence paths:** package.json, dist/collection/registry/server/index.js, dist/skill-bridge/index.js, dist/google/index.js, dist/whisper/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T11:54:20.020Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Validated remote collection import and workspace skill mirroring. - **Rationale:** No concrete malicious chain was found. The package has an explicit runtime capability to install first-party workspace Claude skills from remote registry content, so it warrants a non-blocking warning under the stated policy. - **Files touched:** data/skills/\/, .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:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** dist/collection/registry/server/index.js exports performImport, which fetches a collection bundle., Imported allowlisted SKILL.md, schema.json, and templates are mirrored into .claude/skills/\., dist/skill-bridge/index.js restricts mirrors to validated slugs and an allowlist. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No import-time invocation of performImport or the skill mirror was found., Google OAuth/token handling is explicit runtime integration and targets fixed Google/broker endpoints., Whisper child-process use has fixed arguments for ffmpeg/local whisper-server. ## Affected versions and remediation This report applies to @mulmoclaude/core@0.29.0. - Review the evidence and your use of @mulmoclaude/core@0.29.0 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.
