Vertical Slice Delivery

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

When this skill is selected, you MUST load and obey the accompanying AGENTS.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 [S1]
  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
