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 automatic install hook can place package-shipped skills in the installing user's Claude and Codex skill directories and register messaging tools. This is a first-party agent integration, but it changes agent configuration during installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-07T21:48:55.534Z - **Finished:** 2026-10-07T21:49:23.988Z - **Download time:** 779 ms - **Static scan time:** 134 ms - **AI review time:** 27541 ms - **Total time:** 28454 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 automatic install hook can place package-shipped skills in the installing user's Claude and Codex skill directories and register messaging tools. This is a first-party agent integration, but it changes agent configuration during installation. - **Trigger:** Installing the package as the machine's own supercode under the home directory owner account. - **Impact:** Agent harnesses gain the package's skills and messaging tools without a separate setup command; the inspected source does not establish a malicious payload or credential exposure. - **Evidence paths:** lib/release.mjs, lib/skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-07T21:49:23.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall imports the skills module, copies shipped skill folders into existing Claude and Codex homes, and invokes the native messaging-tool registration command. - **Rationale:** Static inspection confirms automatic first-party agent setup during postinstall, which warrants a warning under the agent integration policy. The reviewed source does not establish a concrete malicious chain or credential exfiltration. - **Files touched:** lib/release.mjs, lib/skills.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs lib/release.mjs automatically after installation., The postinstall calls installSkills and registerTools when the package is the machine's own supercode., The skill installer targets Claude and Codex configuration homes and copies release-shipped skills into their skills folders., The installer preserves symlinks, folders it did not create, and skill folders edited since its recorded hash. - **Evidence against:** The launcher routes commands to package code or its platform-specific native binary; the inspected excerpt does not show a hidden payload., The reviewed MCP and workflow excerpts route calls through the package's Teams daemon or a board address; they do not establish credential theft or another attack. ## Affected versions and remediation This report applies to @volter/supercode@0.5.261. - Review the evidence and your use of @volter/supercode@0.5.261 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.
