## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified in the inspected sources. The package makes API requests as part of its client functionality.

- **Trigger:** Client code invokes the package's flow, session, or event APIs.

- **Impact:** No concrete malicious effect or unrelated credential recipient was established from the inspected excerpts.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T22:08:51.633Z

### AI review details

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

- **Mechanism:** The inspected requests send flow/session data or events using fetch; the session request omits browser credentials.

- **Rationale:** The inspected network activity is consistent with the package's client API functionality, and the manifest has no automatic install hook beyond prepublishOnly. The scanner's callback and secret-pattern hints were not substantiated as malicious behavior by the inspected source.

- **Network endpoints:** https://api.arcyai.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 87.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package exports its bundled entrypoints through dist/index.cjs and dist/index.js., The only install-related lifecycle script is prepublishOnly, which runs a build., The inspected requests send flow data and session configuration through package API calls, with credentials omitted., An event request uses a bearer token and posts events to its configured URL; the inspected excerpt does not establish an unrelated recipient.
