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. 8 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:** 0.5.1 - **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. Static inspection found risky primitives, but they implement documented server-side features with validation and require host/user invocation. There is no install-time/import-time execution, credential collection, hidden exfiltration, or unconsented AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-01T07:20:07.229Z - **Finished:** 2026-07-01T07:21:19.663Z - **Download time:** 520 ms - **Static scan time:** 985 ms - **AI review time:** 70928 ms - **Total time:** 72434 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 malicious attack surface found. Network, filesystem, child\_process, and .claude skill writes are package-aligned server features gated behind exported host/user-invoked workflows, not lifecycle or import-time behavior. - **Trigger:** Host application calls exported feed, registry import, workspace setup, whisper, or collection APIs. - **Impact:** Expected workspace collection/feed/skill synchronization and transcription behavior; no credential harvesting, exfiltration, persistence, or unconsented agent control mutation identified. - **Evidence paths:** package.json, dist/feeds/server/index.cjs, dist/whisper/index.cjs, dist/collection/registry/server/index.cjs, dist/workspace-setup/index.js, dist/skill-bridge/index.cjs, dist/server-cmnH6g2O.cjs - **Review source:** ai\_review - **Reviewed:** 2026-07-01T07:21:19.663Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User/host-invoked feed fetching, model download, local transcription sidecar, and skill/collection file management. - **Rationale:** Static inspection found risky primitives, but they implement documented server-side features with validation and require host/user invocation. There is no install-time/import-time execution, credential collection, hidden exfiltration, or unconsented AI-agent control-surface mutation. - **Files touched:** workspace data/feeds/\, workspace feeds/\, modelsDir/.scratch/utterance-\*.webm, modelsDir/.scratch/utterance-\*.wav, modelsDir/ggml-\*.bin, workspace data/skills/\, workspace .claude/skills/\, workspace data/collections/\/items, workspace config/scheduler/state.json, workspace data/scheduler/logs - **Network endpoints:** https://github.com/receptron/mulmoclaude, https://huggingface.co/ggerganov/whisper.cpp/resolve/main, http://127.0.0.1:\/, http://127.0.0.1:\/inference, https://receptron.github.io/mulmoclaude-collections/index.json, https://raw.githubusercontent.com/receptron/mulmoclaude-collections/main ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle hooks or bin entrypoint., dist/feeds/server/index.cjs fetches configured feed URLs only during refresh and blocks private/loopback DNS/IPs., dist/whisper/index.cjs downloads known Whisper models from Hugging Face and spawns user-configured ffmpeg/whisper-server only via exported transcription APIs., dist/collection/registry/server/index.cjs fetches collection registries from official/user-configured HTTPS URLs and validates bundle paths before writing., dist/skill-bridge/index.cjs mirrors allowlisted skill files into workspace .claude/skills only from explicit workspace/import flows, not at install/import time., Destructive file operations are scoped by slug/path validation and workspace containment checks in inspected files. ## Affected versions and remediation This report applies to @mulmoclaude/core@0.5.1. - Review the evidence and your use of @mulmoclaude/core@0.5.1 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.
