resend-cli@2.25.0
The official CLI for Resend
AI Security Review
scanned 21d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the reviewed entrypoint’s external telemetry sends limited command usage metadata. The scanner’s command-output and credential-exfiltration labels are not supported by the inspected source path.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user runs a CLI command other than update or telemetry.
Impact
The inspected telemetry path does not collect saved credentials or command output.
Mechanism
The CLI records command and runtime metadata and option names, then posts a cli.used event.
AI rationale
The manifest has no install lifecycle hook, and the reviewed entrypoint’s external telemetry sends limited command usage metadata. The scanner’s command-output and credential-exfiltration labels are not supported by the inspected source path.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json maps the resend executable to dist/cli.cjs and lists development, build, check, test, and prepack scripts, with no install lifecycle hook.
- After parsing a CLI command, the entrypoint records usage except for update and telemetry commands.
- Telemetry contains the command, CLI and runtime versions, platform, interaction state, install method, and option names; the option collector omits values.
- The payload is limited to a cli.used event and is posted to PostHog; the inspected collection path does not read saved credentials or command output.
