walkeros-understanding-destinations

What problem does it solve?

This Skill helps developers understand how walkerOS destinations receive, transform, and deliver events to third‑party tools, while clarifying the role of the env pattern in safe integration.

Core Features & Use Cases

• Destination Interface: methods init(context) (optional), push(event, context) (required), pushBatch(batch, context) (optional), config (required).
• Env pattern: dependency injection via env for external APIs to enable testing without mocks.
• Locality: applies to web and server destinations, with examples referenced in the repository.
• Testing strategy guidance: how to test destinations using env mocks and examples in the codebase.
• Configuration: understanding destination settings, mapping, consent, and policy.

Quick Start

• Review the Destination Interface in packages/core/src/types/destination.ts.
• Inspect how env is injected and mocked in tests (see testing with env).
• Create a simple destination mock with a minimal config and simulate pushing an event using a mocked env.
