resend-cli@2.12.0
The official CLI for Resend
AI Security Review
scanned 3mo ago · by lpm-firewall-aiScanner claims of command-output or credential exfiltration are unsupported by the bundled source. Child-process use is limited to telemetry self-flush and credential-store platform integrations; no install-time execution or hostile agent mutation exists.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs the resend CLI.
Impact
Command names, flag names, platform, Node version, and an anonymous ID may reach PostHog.
Mechanism
User-invoked API client with background telemetry flush.
AI rationale
Scanner claims of command-output or credential exfiltration are unsupported by the bundled source. Child-process use is limited to telemetry self-flush and credential-store platform integrations; no install-time execution or hostile agent mutation exists.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- dist/cli.cjs sends default opt-out telemetry to PostHog after CLI commands.
- Telemetry spawns a detached self-invocation to flush a validated local spool file.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Telemetry payload contains command/flag names and runtime metadata, not API-key values or command output.
- Network API usage targets Resend, GitHub release checks, and PostHog telemetry; Resend operations are user-invoked.
- Agent-related files are documentation only; no agent configuration/control-surface writes found.
