# Vertical Slice Delivery

This skill defines default delivery as independently valuable, reviewable vertical slices.

Load and obey its orchestrator `AGENTS.md` that lives next to this `SKILL.md`.

## When to Apply

Use this skill whenever work is being:

- planned
- split into tasks or steps
- delivered incrementally
- resumed after interruption

Any deviation from vertical slice delivery MUST be explicit and justified.

## Core Loop

Each slice = plan -> deliver -> quality gate -> review -> commit. No next slice starts until current slice is committed.
