## About

# Phase Gate Check

Examine the codebase, issues, and project plan. Determine current phase and evaluate.

## How to Use

Define your project phases in a `phases.md` or equivalent document. Each phase needs:

1. **Deliverables** - Concrete, verifiable outputs (not vague goals)
2. **Gate criteria** - What must be true before moving on
3. **Kill questions** - Hard questions that expose whether the phase is actually done

## Phase Template

```
## Phase N - [Name] (Estimated: X weeks)

**Deliverables:**
- [ ] Deliverable 1
- [ ] Deliverable 2
- [ ] Deliverable 3

**Gate Criteria:**
[What must be true before proceeding. Be specific and measurable.]

**Kill Questions:**
- [Hard question that exposes gaps]
- [Another hard question]
```

## Example Phases (Adapt to Your Project)

### Phase 1 - Foundation
**Deliverables:** Core data models, basic CRUD, authentication, CI pipeline.
**Gate:** The system handles the primary happy path end-to-end. It works, even if ugly.

### Phase 2 - Core Features
**Deliverables:** Key features that deliver the primary value proposition.
**Gate:** A user can accomplish the main task the product exists for.

### Phase 3 - Polish & Edge Cases
**Deliverables:** Error handling, input validation, performance optimization, UX refinements.
**Gate:** It handles edge cases gracefully and performs well under expected load.

### Phase 4 - Launch Readiness
**Deliverables:** Monitoring, documentation, deployment automation, security review.
**Gate:** You'd be comfortable with real users depending on it.

## Evaluation Output

1. Current phase based on what's implemented.
2. Checklist of deliverables: done vs remaining.
3. Gate criteria assessment: met / not met / partially met.
4. If gate NOT met: specific actions needed before proceeding.
5. Risks of moving forward without completing the gate.
