This creates an unpinned remote-payload supply-chain surface; no confirmed malicious payload behavior is present in readable source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-13T07:50:13.074Z - **Finished:** 2026-08-13T07:51:10.290Z - **Download time:** 1521 ms - **Static scan time:** 138 ms - **AI review time:** 55555 ms - **Total time:** 57216 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package fetches the latest release archive from its Gitea host and installs its binary. This creates an unpinned remote-payload supply-chain surface; no confirmed malicious payload behavior is present in readable source. - **Trigger:** npm installation - **Impact:** A compromised or changed release endpoint could supply executable code during installation. - **Evidence paths:** package.json, postinstall.mjs, bin/tfcode.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T07:51:10.290Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads and installs an unverified latest remote binary; installs Python dependencies - **Rationale:** This is a real staged remote-payload installation risk, but the readable source does not show exfiltration, stealth persistence, destructive actions, or foreign AI-agent control-surface mutation. Warn rather than block. - **Files touched:** bin/tfcode, bin/app - **Network endpoints:** gitea.toothfairyai.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** postinstall queries the latest remote release, decoupled from package version., postinstall downloads and extracts a remote binary without a checksum/signature check., postinstall installs Python packages into the user's environment. - **Evidence against:** The fetched binary is installed but not executed by postinstall., The JavaScript launcher executes the binary only when the user invokes tfcode., No source evidence of credential harvesting, foreign agent-config writes, or destructive behavior. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
