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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-07T23:22:56.721Z - **Finished:** 2026-10-07T23:23:24.024Z - **Download time:** 520 ms - **Static scan time:** 139 ms - **AI review time:** 26644 ms - **Total time:** 27303 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 npm postinstall path can install a package-owned agent skill into the current user's Claude and Codex configuration homes. This is an agent integration capability; inspected source does not establish credential theft or other active attack behavior. - **Trigger:** Installing or upgrading the machine's own package as the home owner. - **Impact:** The harnesses may load package-provided instructions that enable Supercode Teams operations. - **Evidence paths:** package.json, lib/release.mjs, lib/skills.mjs, skills/supercode-teams/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-07T23:23:24.024Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall invokes \`installSkills()\`, which copies the shipped Supercode Teams skill into each existing Claude or Codex skills directory. - **Rationale:** The package automatically installs its own agent skill into Claude and Codex homes during the machine installation's postinstall. This is a concrete agent integration risk, but the inspected code shows ownership and content-preservation guards and does not establish malicious behavior. - **Files touched:** ~/.claude/skills/supercode-teams, ~/.codex/skills/supercode-teams ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall hook runs \`lib/release.mjs\`., The postinstall path automatically calls \`installSkills()\` for the machine's own installation., \`installSkills()\` targets the user's Claude and Codex harness homes and copies the shipped skill into their skills folders., The copied skill provides agent instructions for operating Supercode Teams. - **Evidence against:** Skill installation runs only when this is detected as the machine's own Supercode installation and the current process owns the home., Existing unmarked folders and symbolic links are preserved; modified marked skills are also preserved., No credential harvesting, unrelated endpoint forwarding, or destructive behavior was identified in the inspected sources. ## Affected versions and remediation This report applies to @volter/supercode@0.5.263. - Review the evidence and your use of @volter/supercode@0.5.263 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.
