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 Windows installer defaults to installing this package's skill into agent configuration directories during global installation. This is a real install-time agent extension side effect, so warn users before publishing. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-29T20:18:06.876Z - **Finished:** 2026-10-29T20:19:07.377Z - **Download time:** 1024 ms - **Static scan time:** 1086 ms - **AI review time:** 58389 ms - **Total time:** 60501 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:** Global installation can add the package's skill to AI-agent configuration directories. - **Trigger:** A global install through the Windows installer, whose Agent option defaults to all. - **Impact:** The installed skill can affect agent context after installation, without the installer explicitly choosing which agent targets to modify. - **Evidence paths:** package.json, install/windows.ps1, dist/install/postinstall.js, .lpm-dependency-evidence-3d1e7203-b86c-44a2-962b-23d996d41edf/0/npm-linux/dist/skill/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:19:07.377Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer sets MAX\_INSTALL\_AGENT during npm install; postinstall then writes the skill under the user's .claude/skills and .agents/skills directories. - **Rationale:** The Windows installer defaults to installing this package's skill into agent configuration directories during global installation. This is a real install-time agent extension side effect, so warn users before publishing. - **Files touched:** ~/.claude/skills/max-cli/SKILL.md, ~/.agents/skills/max-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json declares a postinstall hook that runs install/postinstall.mjs., The Windows installer defaults its Agent parameter to all and passes that choice into the npm install environment., For selected agents, the global postinstall hook installs the package's skill for Claude and/or agents., The skill helper creates target directories and writes SKILL.md files., The helper targets paths under the user's .claude/skills or .agents/skills directories. - **Evidence against:** The postinstall script returns without setup unless the install is global; ordinary installs do not install the skill when MAX\_INSTALL\_AGENT is unset., The browser login code is invoked by the session command and uses a separate temporary browser profile that it removes after login. ## Affected versions and remediation This report applies to @wirecat/max-cli@0.81.0. - Review the evidence and your use of @wirecat/max-cli@0.81.0 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.
