name: slice
description: Suggests the next super thin vertical slice of functionality. Breaks features into the smallest deployable increments. Use when starting a feature or needing the next small step.

Thin Slice Advisor

When invoked with a feature description, suggest the next thinnest possible vertical slice.

Principles

  1. •Vertical not Horizontal: Slice through all layers (UI → domain → data), not by layer
  2. •Deployable: Each slice must be independently deployable
  3. •Valuable: Each slice delivers user-observable behavior (however tiny)
  4. •Tiny: Prefer smaller slices over larger ones (10-30 minutes to implement)
  5. •One at a Time: Suggest only ONE slice, not multiple

Slice Patterns

Good slices (vertical, deployable, valuable):

  • •"Calculate discount for single customer type (regular only)"
  • •"Return hardcoded shipping cost (always $5)"
  • •"Display total without tax"
  • •"Validate email format only (no uniqueness check yet)"

Bad slices (horizontal, technical, too large):

  • •❌ "Build the database schema"
  • •❌ "Create all domain models"
  • •❌ "Implement entire discount system"
  • •❌ "Add validation"

Workflow

  1. •Understand the feature request
  2. •Ask clarifying questions if needed (what's the simplest case?)
  3. •Suggest the thinnest slice that delivers observable value
  4. •Explain what to defer to later slices
  5. •Describe the test that would verify this slice

Output Format

code
**Next Slice**: [One sentence description]

**What it does**: [User-observable behavior]

**What to defer**: [What NOT to implement yet]

**First test**: [The failing test that drives this slice]

**Estimated effort**: [X minutes]

Example

Feature: "Add discount calculation"

Next Slice: Calculate 10% discount for regular customers only

What it does: When order has customer_type='regular', apply 10% discount to total

What to defer:

  • •Premium customer discounts
  • •Discount rules/configuration
  • •Multiple discount types
  • •Discount limits or caps

First test: test_applies_10_percent_discount_for_regular_customer

Estimated effort: 15 minutes

Key Phrases

  • •"Start with the simplest case"
  • •"Hardcode it first, generalize later"
  • •"What's the thinnest slice that proves it works?"
  • •"Defer that to the next slice"
  • •"One behavior at a time"
