Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.41 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The postinstall hook performs automatic setup for this package's own terminal application. The inspected source shows package-aligned runtime installation and no concrete malicious behavior, so the scanner's lifecycle and dynamic-execution signals do not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T06:56:33.800Z - **Finished:** 2026-10-09T06:57:00.810Z - **Download time:** 1539 ms - **Static scan time:** 793 ms - **AI review time:** 24677 ms - **Total time:** 27010 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. The postinstall hook installs the package's matching Python core, including uv setup when needed. - **Trigger:** npm runs the package's postinstall hook. - **Impact:** This creates a user-local runtime for the terminal application; inspected source does not establish an attack surface. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:57:00.810Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook checks the installed core version and calls the installer when it does not match. - **Rationale:** The postinstall hook performs automatic setup for this package's own terminal application. The inspected source shows package-aligned runtime installation and no concrete malicious behavior, so the scanner's lifecycle and dynamic-execution signals do not establish an attack. - **Files touched:** scripts/postinstall.js, dist/install.mjs - **Network endpoints:** https://astral.sh/uv/install.ps1 ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exposes a terminal command and a postinstall hook that installs its own Python core., The installer retrieves uv from astral.sh when uv is absent; this supports the package's core setup., The installer skips setup when an existing core version matches or an external core is configured. - **Evidence against:** The inspected install code places versioned files under the user's .hum directory and installs the matching hum-cli version., The package metadata and inspected installer show no foreign AI-agent configuration writes or credential forwarding. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.41. - Review the evidence and your use of @metaphi-ai/hum@0.2.41 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.
