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. The global-install lifecycle can write the package's own agent skill into user-level agent directories when an agent target is selected. The hook skips that write when MAX\_INSTALL\_AGENT is unset, and the inspected code shows no unrelated credential or data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-29T20:19:01.141Z - **Finished:** 2026-10-29T20:19:49.127Z - **Download time:** 513 ms - **Static scan time:** 1016 ms - **AI review time:** 46455 ms - **Total time:** 47986 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:** A global install can install this package's own agent skill into agent configuration directories. - **Trigger:** The global npm postinstall runs with MAX\_INSTALL\_AGENT set to an agent target; the Windows installer can set this during installation. - **Impact:** This adds package instructions to the selected agent's skill set, an install-time configuration change that users should know about. - **Evidence paths:** package.json, install/postinstall.mjs, dist/install/postinstall.js, .lpm-dependency-evidence-0e3d1b80-bc86-4994-a7d9-a09c01142e48/0/npm-linux/dist/skill/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:19:49.127Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies SKILL.md into the selected agent skill directory under the user's home folder. - **Rationale:** The global-install lifecycle can write the package's own agent skill into user-level agent directories when an agent target is selected. The hook skips that write when MAX\_INSTALL\_AGENT is unset, and the inspected code shows no unrelated credential or data exfiltration. - **Files touched:** ~/.claude/skills/max-cli/SKILL.md, ~/.agents/skills/max-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook proceeds only for global npm installs., When MAX\_INSTALL\_AGENT is set to an agent target, the hook calls installSkill for Claude and/or shared agent directories., The skill installer writes the package's SKILL.md into the selected agent's home skills directory. - **Evidence against:** With MAX\_INSTALL\_AGENT unset or set to none, the hook skips agent skill installation., Browser login starts through an explicit session command and uses a temporary browser profile that is removed afterward., The inspected install and login paths show no unrelated credential collection or external reporting. ## Affected versions and remediation This report applies to @wirecat/max-cli@0.83.0. - Review the evidence and your use of @wirecat/max-cli@0.83.0 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.
