Installing the npm package automatically bootstraps a Python engine. It downloads and executes a remote uv installer when uv is unavailable, then installs hum-cli into ~/.hum/engine. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-27T20:21:26.870Z - **Finished:** 2026-08-27T20:22:44.136Z - **Download time:** 761 ms - **Static scan time:** 9083 ms - **AI review time:** 67421 ms - **Total time:** 77266 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the npm package automatically bootstraps a Python engine. It downloads and executes a remote uv installer when uv is unavailable, then installs hum-cli into ~/.hum/engine. - **Trigger:** npm postinstall when the matching engine is not already installed. - **Impact:** Remote installer and Python engine code can run with the installing user's permissions; the reviewed JavaScript does not show credential exfiltration or foreign agent-config mutation. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-27T20:22:44.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time remote shell bootstrap and Python package installation. - **Rationale:** The package has a real install-time remote code bootstrap and second-stage engine installation, so it should warn. Its behavior appears aligned with setting up its own CLI engine, and no concrete malicious payload or exfiltration is present in the inspected source. - **Files touched:** scripts/postinstall.js, dist/install.mjs, dist/cli.mjs, ~/.hum/engine, ~/.hum/engine-install.json, ~/.hum/update.log - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh, https://metaphi.ai/hum ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The npm postinstall hook imports and invokes the engine installer automatically., If uv is absent, the installer downloads and pipes a remote script into a shell., The hook then installs the matching Python hum-cli engine into the user's home directory., The bundled CLI also has an opt-out background updater for native installs. - **Evidence against:** The reviewed package source contains no confirmed credential exfiltration or browser credential collection., The postinstall behavior is a package-aligned engine bootstrap, not a write to a foreign AI-agent control surface., The credential reads in the doctor command only parse this tool's own ~/.hum/credentials.json for status reporting. ## Public findings ### 1.
