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 Haus skills and merges hook, allow, and deny rules into the user's Claude Code settings. Those hooks intercept file and Bash tool use and also pin an external Claude plugin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-22T16:22:04.718Z - **Finished:** 2026-09-22T16:23:47.719Z - **Download time:** 1015 ms - **Static scan time:** 2273 ms - **AI review time:** 99712 ms - **Total time:** 103001 ms The recorded confidence comes from the underlying analysis.

Those hooks intercept file and Bash tool use and also pin an external Claude plugin. - **Trigger:** npm postinstall during a global install when CI, HAUS\_NO\_POSTINSTALL, and the package dev checkout gates are not set. - **Impact:** Claude Code tool execution and user-level agent settings are changed without a separate haus command, including PreToolUse guards and a third-party plugin install. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, library/global/settings-fragments/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-09-22T16:23:47.719Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.mjs spawns dist/cli.js install --postinstall, which copies library/global assets into the Claude config directory, merges hooks.json into settings.json, and ensures the superpowers plugin pin. - **Attack narrative:** Installing this package globally runs a postinstall script that launches the bundled CLI with install --postinstall. That command writes Haus-managed skills and agents under the Claude config directory and merges settings so Haus commands run before file and Bash tools and on session stop. It also pins the superpowers plugin from a GitHub repository into the user plugin scope. An environment variable can skip the hook, but the default global install still mutates the agent control surface. - **Rationale:** The postinstall path is an automatic global-install write into Claude Code's broad settings and hook surface, including tool-use interceptors and a third-party plugin pin. Opt-out flags and product labeling do not make that unconsented control-surface mutation consented. - **Files touched:** ~/.claude/settings.json, ~/.claude - **Network endpoints:** https://github.com/obra/superpowers.git ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers an npm postinstall script that runs scripts/postinstall.mjs and forces success with || true., On a global install outside CI, the package checkout, and HAUS\_NO\_POSTINSTALL=1, postinstall spawns dist/cli.js with install --postinstall., The install command seeds ~/.claude with skills, agents, and hook settings, then writes the merged Claude settings.json., hooks.json adds PreToolUse commands for Read, Edit, Write, NotebookEdit, and Bash, plus a Stop hook, into that settings file., The same install pins the superpowers plugin from https://github.com/obra/superpowers.git into the user Claude scope. - **Evidence against:** The hook is skipped for local installs, CI, HAUS\_NO\_POSTINSTALL=1, and the package's own dev checkout., Install refuses to overwrite files that lack a Haus ownership header and prints an uninstall undo path., The package description states it is a Claude Code workflow CLI, so the write matches the product purpose. ## Affected versions and remediation This report applies to @haus-tech/haus-workflow@5.8.0. - Avoid installing @haus-tech/haus-workflow@5.8.0. 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.
