Commands executed by Claude Code can be intercepted by package-provided hooks, and an external plugin is installed without an explicit installer command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 5.3.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically changes the user's Claude Code control surface. It writes managed configuration, registers command hooks, and can install a third-party global plugin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T00:09:51.590Z - **Finished:** 2026-09-13T00:11:04.460Z - **Download time:** 758 ms - **Static scan time:** 2066 ms - **AI review time:** 70045 ms - **Total time:** 72870 ms The recorded confidence comes from the underlying analysis.

It writes managed configuration, registers command hooks, and can install a third-party global plugin. - **Trigger:** npm global installation, unless CI or HAUS\_NO\_POSTINSTALL=1 prevents it. - **Impact:** Commands executed by Claude Code can be intercepted by package-provided hooks, and an external plugin is installed without an explicit installer command. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, library/global/settings-fragments/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:11:04.460Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes the CLI installer, which modifies Claude Code settings and plugin state. - **Attack narrative:** Installing this package globally triggers its postinstall script. That script runs the CLI installer, which modifies the user's Claude Code settings, installs hooks for Bash and file operations, and installs a third-party plugin from GitHub at user scope. These changes occur without an explicit Haus setup command. - **Rationale:** The automatic global-install lifecycle mutates a broad AI-agent control surface and installs external plugin code. This meets the policy threshold for unconsented postinstall control-surface mutation. - **Files touched:** ~/.claude/settings.json, ~/.claude/skills/\*, ~/.claude/agents/\*, ~/.claude/haus/install-manifest.json - **Network endpoints:** https://github.com/obra/superpowers.git ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers an npm postinstall hook that runs automatically., The hook runs the installer on every non-CI global installation., The installer writes Claude Code settings and registers four command hooks, including hooks for all Bash and file-edit actions., The automatic installer also adds and installs a third-party Claude Code plugin at user scope. - **Evidence against:** The hook is limited to global installs and supports an environment-variable opt-out., GitHub tokens are used as Authorization headers only for GitHub catalog requests; no separate credential receiver was found. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@5.3.0. - Avoid installing @haus-tech/haus-workflow@5.3.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
