No credential collection, exfiltration, or foreign AI-agent configuration mutation is established. - **Trigger:** npm postinstall; explicit francois CLI extension commands - **Impact:** Installs and registers the Francois desktop app for the current user. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, lib/extensions.js, bin/francois.js, uninstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T13:07:08.878Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified native-app bootstrap and scoped desktop integration - **Rationale:** The lifecycle downloader and quarantine removal are notable, but their behavior is package-aligned and the downloaded archive is pinned by a bundled SHA-256. Source inspection found no concrete malicious chain. - **Files touched:** manifest.json, vendor/, install.js, lib/desktop.js - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** postinstall downloads, verifies, and extracts a native desktop archive., On macOS, postinstall removes quarantine metadata from its extracted vendor payload. - **Evidence against:** The release asset is selected from the bundled manifest and SHA-256 mismatch aborts installation., Default download host is GitHub; no credential harvesting or data exfiltration appears in inspected source., Desktop registration is scoped to Francois shortcuts/app entries, not an AI-agent control surface., Extension installation requires an explicit CLI command and reports plugins as disabled. ## Affected versions and remediation This report applies to francois@0.34.5. - Review the evidence and your use of francois@0.34.5 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.
