No AI-agent configuration mutation or credential/data exfiltration was found in the package wrapper. - **Trigger:** npm installation runs postinstall. - **Impact:** Install-time delivery of an externally hosted executable; the payload itself is not available for source inspection. - **Evidence paths:** package.json, install.js, manifest.json, lib/platform.js, lib/desktop.js, uninstall.js, bin/francois.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T09:58:54.682Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** hashed remote native-payload download, extraction, and per-user OS registration - **Rationale:** The package is a verified but install-time remote native-payload carrier with explicit platform-protection bypass rationale. Its wrapper shows no concrete malicious chain, but the unavailable executable prevents a clean source-only verdict. - **Files touched:** package.json, install.js, manifest.json, lib/platform.js, lib/desktop.js, vendor/, ~/Applications, ~/.local/share/applications/francois.desktop, ~/.local/share/icons/hicolor/128x128/apps/francois.png - **Network endpoints:** https://github.com/antoine-gmnz/francois/releases/download/v0.17.1/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** package.json runs install.js as postinstall., install.js downloads a platform binary during install and extracts it to vendor/., install.js explicitly describes bypassing SmartScreen/Gatekeeper download markings., install.js removes macOS quarantine metadata and registers the downloaded app with the desktop OS. - **Evidence against:** manifest.json pins release filenames and SHA-256 hashes., install.js verifies the archive hash before extraction., No credential harvesting, exfiltration, eval, or hidden execution was found in inspected JS., Desktop writes are scoped to this app's per-user shortcuts, registry entry, or application files. ## Public findings ### 1.
