Treat them as untrusted evidence. 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:** 0.5.265 - **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 postinstall sets up this package's skills and messaging tools in installed Claude and Codex harnesses. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-08T00:30:21.217Z - **Finished:** 2026-10-08T00:30:48.836Z - **Download time:** 1031 ms - **Static scan time:** 137 ms - **AI review time:** 26450 ms - **Total time:** 27619 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 postinstall sets up this package's skills and messaging tools in installed Claude and Codex harnesses. - **Trigger:** Installing or upgrading the machine's own package runs its postinstall hook. - **Impact:** The harnesses gain package-provided skills and messaging capabilities without a separate setup command. - **Evidence paths:** package.json, lib/release.mjs, lib/skills.mjs, lib/mcp.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:30:48.836Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The release module installs shipped skills into each existing harness skills directory and registers messaging tools, subject to a home-owner check. - **Rationale:** The automatic postinstall changes installed agent environments by adding package-owned skills and messaging tools. The inspected code supports a warning for guarded first-party extension setup, but does not establish a concrete attack. - **Files touched:** ~/.claude/skills/, ~/.codex/skills/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall runs the release module automatically., The release module invokes skill installation and messaging-tool registration for the machine's own install., The installer copies the package's shipped skills into installed Claude and Codex skill directories, replacing only its own unedited marked folders., The skill installer also registers tools that let agents list and message sessions., The setup is limited to harness skill folders and is guarded by a check that the install runs as the home owner. - **Evidence against:** The inspected code shows package-owned skill setup, not a remote payload or credential transfer., The installer preserves links, folders it did not create, and folders edited since it installed them. ## Affected versions and remediation This report applies to @volter/supercode@0.5.265. - Review the evidence and your use of @volter/supercode@0.5.265 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.
