We need to construct an order processing module for our e-commerce platform. Decompose this work horizontally across architecture layers from data model up to frontend presentation.
| Checked | Without skill | With skill |
|---|---|---|
| Structures work items across architectural layers starting with data model and progressing through data access, logic, API, and UI. | Passed | Passed |
| Formats every decomposed item using the **Files to Create/Modify:** checkbox list. | Missed | Passed |
| Lists explicit dependencies between architectural layers using Requires: and Blocks:. | Missed | Passed |
The instructions your model reads when the skill loads.
You are breaking down a complex task into smaller, atomic units. Each unit should be independently completable and verifiable.
If a task feels too big, it is too big. Break it down until each piece is obvious.
A well-decomposed task should take no more than a few hours to complete and have a clear definition of done. Aim for tasks that are small, independent, testable, and clearly scoped.
Break by user-visible functionality (each slice is deployable and testable independently):
Feature: User Registration
Slice 1: Email/password signup — form, validation, account creation
Slice 2: Email verification — send email, verify link, UI state
Slice 3: Social login (OAuth) — Google button, OAuth flow, account link
Break by system layer:
Feature: Order Processing
Layer 1: Data Model — entities, migrations
Layer 2: Data Access — repository, CRUD, queries
Layer 3: Business Logic — service, validation rules
Layer 4: API Endpoints — routes, error handling
Layer 5: Frontend — form, API client, loading/error states
Break by process steps:
