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. A global installation automatically configures the user-level Claude Code environment. It writes Haus-managed files and hooks, then can add a third-party plugin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T09:18:12.637Z - **Finished:** 2026-09-12T09:19:40.478Z - **Download time:** 508 ms - **Static scan time:** 2036 ms - **AI review time:** 85296 ms - **Total time:** 87841 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 installation automatically configures the user-level Claude Code environment. It writes Haus-managed files and hooks, then can add a third-party plugin. - **Trigger:** Installing the package globally through npm without HAUS\_NO\_POSTINSTALL=1. - **Impact:** Changes to the user-level AI-agent configuration can affect future Claude Code sessions and load third-party plugin content. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, library/global/settings-fragments/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:19:40.478Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven global Claude Code configuration and plugin installation. - **Rationale:** This is not a concrete malware or data-exfiltration chain, but it automatically mutates a broad user-level AI-agent control surface and installs a third-party plugin. The guarded, tracked implementation lowers the likelihood of malicious intent but does not remove the lifecycle risk. - **Files touched:** ~/.claude/settings.json, ~/.claude/skills/, ~/.claude/agents/, ~/.claude/commands/, ~/.claude/haus/install-manifest.json - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** A global npm install automatically invokes the package CLI., The automatic command writes global Claude Code files and settings., It adds PreToolUse and Stop hooks to the user-level Claude configuration., It automatically installs a pinned third-party Claude plugin in user scope. - **Evidence against:** The hook skips non-global installs, CI, and an explicit opt-out., Managed files are recorded and user-owned files are not overwritten., No self-dependency, obfuscated payload, secret harvesting, or non-package-aligned exfiltration was found. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@5.4.0. - Review the evidence and your use of @haus-tech/haus-workflow@5.4.0 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.
