Installation runs remote shell code to bootstrap uv and installs a separate Python engine outside the npm dependency tree. The inspected JavaScript client communicates with that engine over localhost. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-09-01T11:06:41.951Z - **Finished:** 2026-09-01T11:08:10.955Z - **Download time:** 769 ms - **Static scan time:** 7154 ms - **AI review time:** 81080 ms - **Total time:** 89004 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation runs remote shell code to bootstrap uv and installs a separate Python engine outside the npm dependency tree. The inspected JavaScript client communicates with that engine over localhost. - **Trigger:** npm postinstall when ~/.hum/engine does not contain the matching version. - **Impact:** Remote installer content executes during dependency installation and creates or replaces files under ~/.hum. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T11:08:10.955Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall curl-pipe-shell bootstrap followed by a Python package install. - **Rationale:** The lifecycle hook creates a real supply-chain risk because it executes remotely fetched shell content and installs a separate runtime automatically. The available source does not establish the broader malicious behavior required for a publish block. - **Files touched:** ~/.hum/engine, ~/.hum/engine-install.json, ~/.local/bin/uv - **Network endpoints:** https://astral.sh/uv/install.sh, https://astral.sh/uv/install.ps1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** npm installation automatically invokes a postinstall script., The postinstall calls the engine installer when the local version is absent or differs., The installer downloads and pipes Astral's uv installer into a shell, then installs Python package hum-cli into ~/.hum/engine., The CLI later connects only to an engine bound to 127.0.0.1. - **Evidence against:** The installed engine version is pinned to the npm package version unless an environment override is set., The inspected JavaScript contains no credential collection or external data-exfiltration request., The package writes its own ~/.hum state and engine files, not foreign AI-agent configuration files. ## Public findings ### 1.
