Both work with Node.js. In a kit you pick one, and your agent gets the rule to use only that one.

| How your agent uses it | Track product events with `capture("event", { ...props })`. Name events in snake_case with a past-tense verb (`signup_completed`, `kit_installed`) and identify the user with `identify(id)` after login. Never send sensitive personal data as properties. Use `getPostHog()` from `src/lib/posthog.ts` and call `await client.shutdown()` at the end of each request in serverless environments. | Unhandled errors are reported automatically. For errors you catch, use `Sentry.captureException(error)` and add context with `Sentry.setUser` / `Sentry.setTag`. Never leave `console.error` as the only signal of a production failure. |
