Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection shows an automatic, package-owned setup path that installs the matching Python core. Although setup executes uv's upstream installer if uv is absent, the inspected code provides no evidence of malicious behavior or a concrete attack against the consumer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T06:56:50.840Z - **Finished:** 2026-10-09T06:57:15.667Z - **Download time:** 1019 ms - **Static scan time:** 800 ms - **AI review time:** 23007 ms - **Total time:** 24827 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No malicious attack was identified in the inspected setup path. The postinstall hook installs the package's own versioned Python core when needed. - **Trigger:** Installing the npm package runs its postinstall hook; launching the CLI may select a newer installed package version. - **Impact:** The setup downloads and executes installation tools and creates a local Python environment; no credential theft or agent control-surface mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:57:15.667Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer sets up hum-cli in the package's .hum directory and fetches a matching package version with npm lifecycle scripts disabled. If uv is missing, it runs uv's upstream installer. - **Rationale:** Source inspection shows an automatic, package-owned setup path that installs the matching Python core. Although setup executes uv's upstream installer if uv is absent, the inspected code provides no evidence of malicious behavior or a concrete attack against the consumer. - **Files touched:** package.json, scripts/postinstall.js, dist/install.mjs - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest declares a postinstall hook that runs the package's own setup script., The hook checks whether this version's Python core is installed and installs it if missing., The installer uses a package-version-pinned hum-cli dependency; its update fetch uses npm with scripts disabled., If uv is absent, setup runs its upstream installer from astral.sh. - **Evidence against:** The inspected postinstall path installs this package's own core rather than mutating an AI-agent control surface., The package update fetch is version-specific and passes --ignore-scripts. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.43. - Review the evidence and your use of @metaphi-ai/hum@0.2.43 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
