name: lfe-to-issues description: Break the PRD into independently-demoable vertical slice issues. Use in the Architect sub-pipeline after to-prd completes. Requires human approval of slices.

LFE To Issues

Position in Pipeline

Phase: 1 (Architect sub-pipeline, Step 3)
Persona: Architect
Input: .plans/02_prd.md
Output: .plans/03_slices.md
Gate: 🛑 Human must approve slices before proceeding

Process

1. Read input

Read .plans/02_prd.md as the source of truth — it carries this step's inputs, not the conversation.

2. Draft vertical slices

Break the PRD into tracer bullet slices. Each slice is a thin vertical cut through ALL integration layers end-to-end, NOT a horizontal slice of one layer.

Slices are either:

AFK — can be implemented and merged without human interaction
HITL — requires a human decision, design review, or external dependency

Prefer AFK over HITL where possible.

Vertical slice rules:

Each slice delivers a narrow but COMPLETE path through every layer (schema, API, UI, tests)
A completed slice is demoable or verifiable on its own
Prefer many thin slices over few thick ones

3. Present to human

Present the proposed breakdown as a numbered list. For each slice show:

Title: short descriptive name
Type: HITL / AFK
Blocked by: which other slices must complete first
User stories covered: which user stories this addresses

Ask the human:

Does the granularity feel right?
Are the dependency relationships correct?
Should any slices be merged or split further?
Are the correct slices marked as HITL and AFK?

🛑 Iterate until the human approves the breakdown.

4. Write coordination file

Save approved slices to .plans/03_slices.md:

---
phase: architect
step: 3_slices
status: complete
timestamp: <ISO-8601>
source: .plans/02_prd.md
total_slices: <N>
approved_by_human: true
---

## Slice 1: <Title>
- **Type**: AFK
- **Blocked by**: None
- **Acceptance criteria**:
  - [ ] Criterion 1
  - [ ] Criterion 2

## Slice 2: <Title>
- **Type**: AFK
- **Blocked by**: Slice 1
- **Acceptance criteria**:
  - [ ] Criterion 1

AC-writing discipline

Write each acceptance criterion as a falsifiable, prose statement of the observable end-state — not as a literal search/regex string (reproducing a pattern in an AC re-triggers that pattern's own check). For slices that create, edit, or archive structured documentation, draft the ACs with the doc-edit AC-design patterns the Architect's Plan-Composition Discipline enumerates — section-name conformance, cross-reference semantic-inversion anchoring, byte-identity sidecar fixtures, section-boundary extraction caveats (numeric-prefix collision + non-numeric headings), cross-file scope symmetry, edit-mechanism ACs, and archive-move ACs — so the downstream active_plan.md inherits them rather than rediscovering them at Inspector time.
