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 hook can install this package's own agent skill and register its messaging tools in Claude and Codex environments. This is a guarded, package-owned agent integration; the inspected code did not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-08T00:05:32.231Z - **Finished:** 2026-10-08T00:06:01.454Z - **Download time:** 780 ms - **Static scan time:** 144 ms - **AI review time:** 28299 ms - **Total time:** 29223 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 hook can install this package's own agent skill and register its messaging tools in Claude and Codex environments. This is a guarded, package-owned agent integration; the inspected code did not establish a concrete attack. - **Trigger:** npm installation or upgrade, when the package identifies itself as the machine's own supercode. - **Impact:** Agents may gain this package's skills and messaging tools without a separate harness-side setup step. - **Evidence paths:** package.json, lib/release.mjs, lib/skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:06:01.454Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall path invokes skill installation and tool registration; skill files are copied into existing harness homes, with checks that preserve unmarked or user-edited folders. - **Rationale:** The package has an automatic postinstall that can set up its own skill and messaging tools in Claude and Codex homes. This is a guarded first-party agent extension lifecycle risk, so warn rather than block; inspected source did not establish malicious attack behavior. - **Files touched:** lib/release.mjs, lib/skills.mjs, ~/.claude/skills/, ~/.codex/skills/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs lib/release.mjs automatically after installation., The postinstall path imports installSkills and registerTools when the package is identified as the machine's own supercode., installSkills copies the package's skill into existing Claude and Codex harness homes, replacing eligible prior package-managed copies., The skill installer preserves symlinks, unmarked folders, and edited managed copies, limiting which existing content it replaces., The CLI routes commands to package modules or the platform binary; this does not establish an independent attack. - **Evidence against:** The inspected agent integration installs this package's own skill and registers its own messaging tools; no concrete credential theft or unrelated network exfiltration was established., No source inspected established destructive behavior, stealth persistence, or a remote payload execution chain. ## Affected versions and remediation This report applies to @volter/supercode@0.5.264. - Review the evidence and your use of @volter/supercode@0.5.264 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.
