This is a package-owned service, but it is an install-time persistence side effect. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-11T10:20:46.824Z - **Finished:** 2026-08-11T10:21:33.475Z - **Download time:** 508 ms - **Static scan time:** 1179 ms - **AI review time:** 44962 ms - **Total time:** 46651 ms ## Security analysis ### Published attack-surface review - **Summary:** Install can start a local background proxy; global install also persists it at user login. This is a package-owned service, but it is an install-time persistence side effect. - **Trigger:** npm postinstall; global installs invoke enable - **Impact:** A proxy process may run after installation and at subsequent logins. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/preuninstall.js, dist/index.js, defaults/catalog.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T10:21:33.475Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached daemon plus per-user login entry - **Rationale:** Source confirms unconsented install-time background execution and user-login persistence, warranting a warning. It is not a concrete malicious chain: the service is package-aligned, documented, guarded, and its network behavior is its proxy function. - **Files touched:** package.json, scripts/postinstall.js, scripts/preuninstall.js, dist/index.js, defaults/catalog.json - **Network endpoints:** https://integrate.api.nvidia.com/v1, https://opencode.ai/zen/v1, https://openrouter.ai/api/v1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall and preuninstall hooks., scripts/postinstall.js starts a detached daemon on local installs., Global postinstall invokes enable, writing a user login-start entry., dist/index.js creates LaunchAgent/systemd-user/Startup persistence. - **Evidence against:** Lifecycle invokes the package's own dist/index.js only., Persistence is documented and has opt-out, CI, npx, and source-check guards., Network requests proxy user-configured LLM traffic to configured providers., No credential harvesting or unrelated exfiltration found. ## Public findings ### 1.
