Excerpt

Planning and Task Breakdown

Overview

Decompose work into small, verifiable tasks with explicit acceptance criteria. Good task breakdown is the difference between an agent that completes work reliably and one that produces a tangled mess. Every task should be small enough to implement, test, and verify in a single focused session.

When to Use

You have a spec and need to break it into implementable units
A task feels too large or vague to start
Work needs to be parallelized across multiple agents or sessions
You need to communicate scope to a human
The implementation order isn't obvious

When NOT to use: Single-file changes with obvious scope, or when the spec already contains well-defined tasks.
