SP 00 3 STAGE SKIP DECISION

# Stage 0-3 Prompt: Automatic Stage 1~2 Execution Determination

## CONTEXT

This stage determines whether to re-execute Stage 1 (Project Foundation Setup) and Stage 2 (Research) in a new release.

Release 1.0 (initial) always executes Stage 1~2, but Release 2.0 onward is conditionally executed based on technology stack changes.

---

## OBJECTIVE

Compare new requirements with the existing technology stack and **automatically determine** whether Stage 1 and Stage 2 need to be executed.

**Validation Criteria:**
- Stage 1 determination: Execute/Skip specified + rationale
- Stage 2 determination: Execute/Partial execution/Skip specified + rationale
- Next Stage decision: Enter Stage 3 or Stage 1/2

---

## CONSTRAINTS

### MUST DO
- Compare new requirements (collected in 0-3) with existing CLAUDE.md
- Automatically classify based on 5 determination criteria
- Specify rationale at technical level (no abstract descriptions)
- Check dependencies (e.g., GraphQL adoption → Choose Apollo Server)

### MUST NOT DO
- Subjective determination (execute without rationale)
- Excessive scope expansion (execute only what is necessary)
- Change already confirmed technology stack

### SCOPE
- Read: New requirements, existing CLAUDE.md
- Write: `00_STAGE_SKIP_DECISION.md` (determination table + rationale)
- Coverage: Stage 1, Stage 2 determination only (other Stages are always executed)
