arcy.js@0.4.0
ARCY, the universal JavaScript utility for embedding an AI agent that talks to, learns from, and acts on behalf of your users.
AI Security Review
scanned 12d ago · by lpm-firewall-aiThe source ties the flagged callback to ARCY’s own widget telemetry, with bounded measurement collection when consent is absent. The manifest has no install hook, and the stage entrypoint uses an offline fetch stub.
Static reason
One or more suspicious static signals were detected.
Trigger
An embedded widget observes events and flushes queued batches on a timer or when its batch threshold is reached.
Impact
No package install-time mutation, unrelated credential transfer, or remote code execution was established.
Mechanism
The client sends event JSON to the telemetry endpoint using its SDK token and omits browser credentials; the stage helper injects a fixture fetch.
AI rationale
The source ties the flagged callback to ARCY’s own widget telemetry, with bounded measurement collection when consent is absent. The manifest has no install hook, and the stage entrypoint uses an offline fetch stub.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes the runtime entrypoints and defines only a prepublishOnly release check and build hook.
- The runtime POST batches event data to ARCY’s telemetry API using the SDK token and omitting browser credentials.
- Without consent, collection is limited to an event allowlist and is disabled when Do Not Track or Global Privacy Control is signaled; field descriptions use element metadata rather than entered values.
- The stage helper injects an offline fetch with fixture responses and a synthetic session token.
- The declared LiquidJS and Marked dependencies use template and Markdown parser entrypoints; their inspected manifests show build and test scripts.
