Guidelines

Story Sizing

Each story should be:

• •Small enough to implement in one AI context window (~30 min of work)
• •Self-contained with clear acceptance criteria
• •Independently testable

If a feature is too large, break it into multiple stories.

Priority Rules

• •Priority 1: Foundation/setup stories (must be done first)
• •Priority 2-3: Core functionality
• •Priority 4-5: Secondary features
• •Priority 6+: Nice-to-haves, polish

Story ID Format

Use format: STORY-001, STORY-002, etc.

Acceptance Criteria

Each criterion should be:

• •Specific and testable
• •Binary (either done or not done)
• •Written as "When X, then Y" or imperative statements

Good Examples

### STORY-001: Initialize project structure
**Priority:** 1
**Description:** Set up the basic project structure with necessary configuration files.

**Acceptance Criteria:**
- [ ] package.json exists with project name and dependencies
- [ ] TypeScript configured with tsconfig.json
- [ ] Basic folder structure created (src/, tests/)
- [ ] .gitignore configured for Node.js project

Bad Examples

### STORY-001: Build the app
**Description:** Make the whole application work

**Acceptance Criteria:**
- [ ] App works

(Too vague, too large, not testable)

After Generation

After generating the PRD, inform the user:

1. •The PRD has been created
2. •They should review and adjust priorities/stories as needed
3. •To convert to Ralph's JSON format, run: /convert-to-json
4. •Then run ralph to start autonomous implementation
