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 starts the CLI and installs Haus-managed Claude Code configuration and hooks. This is a first-party agent extension setup, but it occurs without an interactive approval at install time. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-19T13:40:09.255Z - **Finished:** 2026-09-19T13:41:13.240Z - **Download time:** 256 ms - **Static scan time:** 2163 ms - **AI review time:** 61566 ms - **Total time:** 63985 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 starts the CLI and installs Haus-managed Claude Code configuration and hooks. This is a first-party agent extension setup, but it occurs without an interactive approval at install time. - **Trigger:** Installing the package globally with npm outside CI, unless HAUS\_NO\_POSTINSTALL=1 is set. - **Impact:** It can alter the user's global Claude Code behavior and install plugins; the inspected network requests use GitHub credentials only for the fixed catalog service. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T13:41:13.240Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches the CLI to write global Claude configuration and hook entries. - **Rationale:** The automatic global Claude configuration mutation warrants a warning as an agent extension lifecycle risk. Static inspection did not substantiate the scanner's claim of default credential exfiltration or other concrete malware behavior. - **Files touched:** ~/.claude/, ~/.claude/settings.json - **Network endpoints:** api.github.com, raw.githubusercontent.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest runs a postinstall hook., That hook runs only for global npm installs and invokes the bundled install command., The install command writes Haus-managed Claude configuration, hooks, and plugins., GitHub credentials are sent only as an Authorization header to the fixed GitHub catalog API. - **Evidence against:** No source evidence showed credential export to an unrelated or operator-configurable endpoint., The flagged request scripts are local workflow, archive, and report utilities; no network send sink was found in them. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@5.7.0. - Review the evidence and your use of @haus-tech/haus-workflow@5.7.0 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.
