This is an opaque staged runtime install, but the inspected code does not establish secret theft or destructive behavior. - **Trigger:** npm postinstall - **Impact:** Remote installer and Python package code can run with the installing user's privileges and create files under the user's home directory. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T22:08:00.878Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic remote shell bootstrap and Python engine installation - **Rationale:** The automatic remote bootstrap and staged Python installation are a material supply-chain risk and cannot be fully assessed from this npm snapshot. The visible code is transparent about that behavior and lacks a concrete malicious payload, so a warning is more proportionate than a block. - **Files touched:** ~/.hum/engine, ~/.hum/engine-install.json, ~/.local/bin/uv - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The package runs a postinstall hook that invokes its engine installer automatically., When uv is absent, the installer downloads and executes a shell or PowerShell script from astral.sh., The installer then installs a separate Python package into a home-directory virtual environment, leaving its runtime outside this snapshot. - **Evidence against:** The staged package version is fixed to the npm package version unless an environment override is supplied., The inspected JavaScript reads its own ~/.hum credentials only for local status reporting; no browser credential collection or exfiltration was found., No foreign AI-agent configuration mutation was found in the inspected install path. ## Public findings ### 1.
