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:** 3.5.1 - **Selected version is latest:** Yes - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. The install lifecycle refreshes existing Comms CLI skill files for supported agent integrations. This is an automatic package-owned extension update, with no confirmed broader attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-07T05:08:32.042Z - **Finished:** 2026-10-07T05:09:17.034Z - **Download time:** 1280 ms - **Static scan time:** 580 ms - **AI review time:** 43131 ms - **Total time:** 44992 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:** The install lifecycle refreshes existing Comms CLI skill files for supported agent integrations. This is an automatic package-owned extension update, with no confirmed broader attack behavior. - **Trigger:** Installing the npm package triggers its postinstall script. - **Impact:** An existing Comms CLI skill definition is refreshed without a separate user command; no credential theft or remote execution is established by the inspected code. - **Evidence paths:** dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T05:09:17.034Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script checks supported global agent skill paths and overwrites an existing skill file with this package's content. - **Rationale:** The postinstall hook automatically refreshes existing package-owned skill files across supported agent integrations, which warrants a warning under the extension lifecycle policy. The inspected behavior does not establish a concrete malicious attack or justify a publish block. - **Files touched:** ~/.claude/skills/comms-cli/SKILL.md, ~/.codex/skills/comms-cli/SKILL.md, ~/.cursor/skills/comms-cli/SKILL.md, ~/.gemini/skills/comms-cli/SKILL.md, ~/.pi/agent/skills/comms-cli/SKILL.md, ~/.agents/skills/comms-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall script during installation., That hook updates skills already present in supported agent directories without an explicit command., The update writes this package's skill content into those existing skill files. - **Evidence against:** Updates are limited to existing package-owned skill files across named agent integrations; the inspected code does not show credential collection, network transmission, or broader agent configuration changes. ## Affected versions and remediation This report applies to @doist/comms-cli@3.5.1. - Review the evidence and your use of @doist/comms-cli@3.5.1 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.
