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 npm installation automatically configures the user's Claude Code directory, including hooks and permission rules, and installs a pinned external plugin. The package has no confirmed unrelated data-exfiltration endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-01T13:01:12.862Z - **Finished:** 2026-09-01T13:02:20.492Z - **Download time:** 1016 ms - **Static scan time:** 2426 ms - **AI review time:** 64187 ms - **Total time:** 67630 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 npm installation automatically configures the user's Claude Code directory, including hooks and permission rules, and installs a pinned external plugin. The package has no confirmed unrelated data-exfiltration endpoint. - **Trigger:** A global npm install runs postinstall unless CI or HAUS\_NO\_POSTINSTALL=1 prevents it. - **Impact:** Changes can affect all Claude Code sessions for that user and introduce third-party plugin code. - **Evidence paths:** scripts/postinstall.mjs, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T13:02:20.492Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global Claude Code configuration and plugin installation. - **Rationale:** This is a real lifecycle risk because it automatically modifies global AI-agent configuration and installs third-party plugin code. The behavior is package-aligned and transparent enough to downgrade rather than block, but it should not be silently published as clean. - **Files touched:** ~/.claude/settings.json, ~/.claude/haus/install-manifest.json, dist/cli.js, scripts/postinstall.mjs - **Network endpoints:** https://github.com/pcvelz/superpowers.git, https://api.github.com/repos/WeAreHausTech/haus-workflow-catalog ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook automatically runs during global npm installs and invokes the CLI installer., The invoked installer writes global Claude Code files and merges hooks, allow rules, deny rules, and ask rules into its settings., The installer automatically manages a pinned third-party Claude plugin from GitHub., GitHub credentials may be read from environment variables or the gh CLI and sent only as authorization to the package-aligned catalog API. - **Evidence against:** The lifecycle hook is limited to global installs, skips CI and local source checkouts, and has an opt-out variable., The observed network code targets the named GitHub catalog API; no unrelated credential receiver or payload endpoint was found., File replacement checks ownership markers and preserves user-owned files unless forced. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@4.9.0. - Review the evidence and your use of @haus-tech/haus-workflow@4.9.0 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.
