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 flagged process and network behavior belongs to the CLI’s explicit managed-binary install/update workflow, which downloads from the project’s GitHub releases and verifies checksums. The library entry point exports CLI functions without invoking them at import time, and no malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T22:56:09.180Z - **Finished:** 2026-10-31T22:56:50.548Z - **Download time:** 1272 ms - **Static scan time:** 1638 ms - **AI review time:** 38457 ms - **Total time:** 41368 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 attack was identified; process execution and network access serve the CLI’s managed-binary installation and account features. - **Trigger:** Managed-binary download and execution are triggered by explicit install or update commands; account requests require invoking an API command. - **Impact:** No unauthorized collection, account action, or automatic execution was identified. An explicit install or update changes the user-local Prefactor installation. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T22:56:50.548Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install and update fetch release assets from GitHub, validate their SHA256 checksum, and manage the Prefactor CLI binary. Account commands use the Prefactor API with user-provided or previously configured credentials. - **Rationale:** The flagged process and network behavior belongs to the CLI’s explicit managed-binary install/update workflow, which downloads from the project’s GitHub releases and verifies checksums. The library entry point exports CLI functions without invoking them at import time, and no malicious behavior was found. - **Files touched:** $HOME/.prefactor/bin/prefactor, $HOME/.prefactor/install.json - **Network endpoints:** github.com/prefactordev/typescript-sdk/releases/download, github.com/prefactordev/typescript-sdk/releases/latest/download, app.prefactorai.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines a CLI binary and a separate library entry point., The library entry point exports runCli but does not invoke it automatically., Binary installation is registered as an explicit CLI command., The installer fetches release assets from the project’s GitHub releases and checks them against a SHA256 manifest. - **Evidence against:** The CLI can download, extract, and run its own managed binary during an explicit install or update command., The package includes API commands that authenticate with the user’s Prefactor account when invoked. ## Affected versions and remediation This report applies to @prefactor/cli@0.4.1. - Review the evidence and your use of @prefactor/cli@0.4.1 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.
