## Security analysis

### Published attack-surface review

- **Summary:** During npm install, the package fetches a mutable latest release and stages its binary in bin/. It also installs Python packages through pip with system-package protections bypassed.

- **Trigger:** npm install

- **Impact:** Unpinned remote artifacts can introduce code that runs at later tfcode invocation; pip installation can execute third-party package install hooks during installation.

- **Evidence paths:** package.json, postinstall.mjs, bin/tfcode.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-21T17:55:43.178Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall remote binary staging and pip dependency installation

- **Rationale:** The source establishes risky install-time remote payload and dependency acquisition but not malicious intent or a confirmed payload. Warn so the mutable execution chain is visible.

- **Files touched:** bin/tfcode, bin/app

- **Network endpoints:** https://gitea.toothfairyai.com/api/v1/repos/ToothFairyAI/tf\_code/releases/latest, https://gitea.toothfairyai.com/ToothFairyAI/tf\_code/releases/download/v${version}/${filename}

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** npm postinstall invokes a networked installer., Installer resolves the remote latest release, not the manifest version., It downloads and installs an unsigned archive into bin/., Postinstall also runs pip install with --user and --break-system-packages.

- **Evidence against:** No source evidence of credential harvesting or unrelated exfiltration., The launcher only executes the installed binary after an explicit tfcode command., README describes the binary and workspace integration as package functionality.
