## FAQ

### How do I authenticate with Heystack?

You sign in using Heystack via OAuth, so there are no API keys to manually paste.

### What can the heystack-setup skill do?

It detects your runtime, such as Next.js or Node, and configures the correct OpenTelemetry entry or OTLP path.

### Is my code content sent to Heystack when using the timeline feature?

No, only file paths and one-line command descriptions are sent; file contents, diffs, and prompts are never transmitted.
