outbox-handler-add

What problem does it solve?

This Skill prevents unsafe, non-atomic external dispatches by guiding you to add a new outbox target handler that works with the system’s commit-then-enqueue and replay-safety guarantees.

Core Features & Use Cases

• Handler contract scaffolding: Defines the required coroutine signature, idempotency-key usage, and failure/retry/dead-letter behavior for an outbox handler.
• Application wiring checklist: Walks you through adding the client wrapper, outbox dispatch builder, lifespan registration in OutboxWorker, and the required flow changes to emit OutboxIntent instead of making inline calls.
• Test and documentation integration: Ensures you add a focused dispatch unit test and update PRD/ADR and known-gap documentation as needed for the new external target.

Quick Start

Use the outbox-handler-add skill to add a new outbox target called X so your saga steps enqueue asynchronous dispatches with correct idempotency and worker delivery semantics.
