Domain Review Before Implementation

The Trigger

Use this skill when you're about to:

• Dispatch a Task() for implementation work
• Start coding from a plan or task description
• Send a prompt to a subagent that will write code

The prompt you write IS the brief. If you're about to send an implementation agent a task, that task description needs review first.

Ask yourself: "Am I about to have code written (by me or an agent)?" If yes → domain review first.

Overview

Core principle: Task briefs contain design flaws. Domain experts catch them before implementation, not code reviewers after.

Real-world data: Phase 4A Task 16 (RiverGraph serialization) - "straightforward" brief reviewed by domain expert found 8 issues (3 critical type safety bugs, 3 important design gaps, 2 minor improvements). Cost: 5 minutes review. Savings: hours of debugging and refactoring.
