Vertical Slice Delivery

This skill defines the default delivery methodology for planning and shipping
work as independently valuable, reviewable vertical slices.

Load and obey its 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 = one commit + one review. No slice begins until the previous is approved.

1. IMPLEMENT — one behavioral slice only
2. COMMIT — with slice ID and conventional message feat(scope): [S1] description
3. STOP — mandatory review (do not proceed)
4. WAIT — approved → next slice, blocked → fixup and re-review

Key Concepts

Concept	Summary
Behavioral Slices	Deployable behaviors, not technical tasks. "Can a user demo this alone?"
Role Separation	Delivery writes code; Review audits and approves. Self-approval prohibited.
Git Discipline	Status before work, explicit paths, fixups for amendments
Code Guidelines	Improve touched code only, no speculative abstraction
