opik@2.2.127
Opik TypeScript and JavaScript SDK
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe package has no install lifecycle hook, and the reviewed CLI telemetry targets Comet and supports an opt-out. The SDK’s default endpoint and host-derived client identifier are consistent with its stated service; no concrete attack behavior was found.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Running the CLI sends analytics; importing and using SDK APIs activates their service requests.
Impact
The observed network activity is package-aligned analytics and SDK service traffic; no independent credential exfiltration or harmful action was established.
Mechanism
CLI analytics includes a hashed host and user identifier plus command and runtime metadata, with an environment-variable opt-out. SDK requests default to the Comet Opik API.
AI rationale
The package has no install lifecycle hook, and the reviewed CLI telemetry targets Comet and supports an opt-out. The SDK’s default endpoint and host-derived client identifier are consistent with its stated service; no concrete attack behavior was found.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json routes imports to SDK bundles and the CLI, with no install lifecycle hook.
- CLI analytics sends invocation metadata to Comet’s stats endpoint and can be disabled with OPIK_ANALYTICS_ENABLE.
- The SDK defaults to Comet’s Opik API; its client identifier is derived from the local hostname and username.
- The inspected dependencies expose terminal styling, INI parsing, and Anthropic provider functionality through package entrypoints.
- The inspected SDK entrypoints re-export library APIs; no separate attack behavior was identified.
