Claude Code tool use and stop events are hooked to this package, and a foreign always-on plugin is installed into the user agent config without an install-time consent prompt. - **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:** 5.10.0 - **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 install automatically runs haus install --postinstall, which writes Claude Code skills, hook commands, and security rules into the user Claude config and pins a third-party plugin. The user is not prompted; the only gates are global scope, absence of CI, and an opt-out environment variable. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-26T00:07:56.958Z - **Finished:** 2026-09-26T00:09:04.168Z - **Download time:** 765 ms - **Static scan time:** 2207 ms - **AI review time:** 64236 ms - **Total time:** 67210 ms The recorded confidence comes from the underlying analysis.

The user is not prompted; the only gates are global scope, absence of CI, and an opt-out environment variable. - **Trigger:** npm postinstall during a global install of this package. - **Impact:** Claude Code tool use and stop events are hooked to this package, and a foreign always-on plugin is installed into the user agent config without an install-time consent prompt. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, library/global/settings-fragments/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T00:09:04.168Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.mjs spawnSyncs dist/cli.js install --postinstall, which merges haus hooks into Claude settings.json and ensures the superpowers marketplace plugin. - **Attack narrative:** Installing this package globally runs its postinstall script, which launches the bundled CLI with install --postinstall. That command seeds the user Claude config with haus skills and agents, writes PreToolUse and Stop hooks that call haus, and pins the third-party superpowers plugin for always-on activation. There is no consent prompt; CI and HAUS\_NO\_POSTINSTALL only skip the write. This is unconsented mutation of the broad Claude agent control surface at install time. - **Rationale:** The npm postinstall hook unconditionally starts a global Claude config write when the install is global, outside CI, and not opted out. That write changes ~/.claude settings and enables a third-party always-on plugin, which is an unconsented broad agent control-surface mutation. - **Files touched:** ~/.claude, ~/.claude/settings.json - **Network endpoints:** https://github.com/obra/superpowers.git ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers a postinstall script that always invokes scripts/postinstall.mjs., On a global npm install the script spawns the bundled CLI as install --postinstall with no consent prompt., That install writes skills, agents, hooks, and security rules into ~/.claude or CLAUDE\_CONFIG\_DIR, including settings.json., The shipped hook fragment registers PreToolUse and Stop commands that invoke haus on Read, Edit, Write, and Bash., The same install pins the third-party superpowers plugin from github.com/obra/superpowers.git with always activation. - **Evidence against:** The hook skips non-global installs, CI, HAUS\_NO\_POSTINSTALL=1, and the package dev checkout., The package documents itself as a Claude Code workflow CLI and prints an uninstall command after the write. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@5.10.0. - Avoid installing @haus-tech/haus-workflow@5.10.0. 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.
