Runtime then launches that engine locally. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-25T17:05:45.101Z - **Finished:** 2026-08-25T17:07:31.815Z - **Download time:** 1013 ms - **Static scan time:** 7681 ms - **AI review time:** 98019 ms - **Total time:** 106714 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation silently bootstraps uv from astral.sh and installs the separate hum-cli engine. Runtime then launches that engine locally. - **Trigger:** npm postinstall; later invocation of hum - **Impact:** Installs and executes an external AI coding-agent engine outside the npm package. - **Evidence paths:** package.json, scripts/postinstall.js, bin/hum.js, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T17:07:31.815Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote installer bootstrap and detached local engine launch - **Rationale:** The package has a real install-time remote bootstrap and external engine installation, warranting a warning. Source inspection did not establish malicious behavior that meets the block threshold. - **Files touched:** scripts/postinstall.js, bin/hum.js, dist/cli.mjs - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall downloads and pipes Astral's installer into a shell, then installs hum-cli., The CLI spawns a detached hum-engine process when invoked. - **Evidence against:** No credential harvesting, exfiltration endpoint, or foreign AI-agent config mutation was found., The bundled CLI connects only to a localhost engine. ## Public findings ### 1.
