Core Package

@trigger.dev/core - shared types, schemas, and utilities used across the SDK, CLI, and webapp.

Critical Import Rule

NEVER import the root (@trigger.dev/core). Always use subpath imports:

import { ... } from "@trigger.dev/core/v3";
import { ... } from "@trigger.dev/core/v3/utils";
import { ... } from "@trigger.dev/core/logger";
import { ... } from "@trigger.dev/core/schemas";

Cross-Cutting Impact

Changes here affect both the customer-facing SDK and the server-side webapp. Exercise caution - breaking changes can affect deployed user tasks and the platform simultaneously.
