Ralph Add

Purpose

Add new user stories to an existing prd.json while preserving the status of all completed stories. Use this when you want to extend a project with new features without losing progress.

Arguments

• <prd-file.md> — Path to PRD markdown file containing ONLY the new stories to add
• --inline — Interactively define new stories (no file needed)

Behavior

What It Preserves

• All existing stories and their passes status
• Existing story IDs, priorities, and all fields
• Project name and description

What It Does

1. Reads existing scripts/ralph/prd.json
2. Parses new stories from the provided PRD file or inline input
3. Validates no duplicate story IDs
4. Assigns priorities to new stories (starting after highest existing priority)
5. Merges new stories into the existing array
6. Writes updated prd.json

Duplicate ID Handling

If a new story has an ID that already exists:

• Warn the user about the conflict
• Skip the duplicate story (do not overwrite)
• Continue with remaining new stories

Workflow

Option 1: From PRD File

/ralph-add docs/new-features.md

The PRD file should contain ONLY the new stories in standard PRD format:

# New Features

## Feature: User Notifications
Users receive email notifications for important events.

### Acceptance Criteria
- Email sent on new message
- Email sent on mention
- Unsubscribe link in all emails

### Notes
Use SendGrid for email delivery.

Option 2: Inline Definition

/ralph-add --inline

Then provide story details interactively or in the prompt.

Priority Assignment

New stories receive priorities starting AFTER the highest existing priority:

Before (existing prd.json):

{
  "userStories": [
    { "id": "setup-001", "priority": 1, "passes": true },
    { "id": "auth-001", "priority": 2, "passes": true },
    { "id": "crud-001", "priority": 3, "passes": false }
  ]
}

After adding 2 new stories:

{
  "userStories": [
    { "id": "setup-001", "priority": 1, "passes": true },
    { "id": "auth-001", "priority": 2, "passes": true },
    { "id": "crud-001", "priority": 3, "passes": false },
    { "id": "notif-001", "priority": 4, "passes": false },
    { "id": "export-001", "priority": 5, "passes": false }
  ]
}

Story ID Convention

Generate IDs following existing patterns in the project:

Scan existing IDs to match the naming convention used in the project.

Stack Detection

Follow the same stack detection rules as /ralph. Detect the project stack from the project root before assigning scaffold skills. See /ralph SKILL.md "Stack Detection" section for the indicator table.

Scaffold Skill Auto-Detection

Apply the same rules as /ralph for auto-adding scaffoldSkill. Use the scaffold skill matching the detected stack:

Do NOT add scaffoldSkill for:

• Bug fixes
• Refactoring
• Configuration/setup
• Static content
• UI-only changes
• Extending existing features

prd.json Story Schema

New stories must follow this schema:

{
  "id": "string (kebab-case, e.g., notif-001)",
  "title": "string (short, imperative)",
  "priority": "number (auto-assigned)",
  "description": "string (what to implement)",
  "acceptanceCriteria": ["string (testable criteria)"],
  "testCriteria": ["string (specific test assertions)"],
  "testFiles": ["string (test file paths)"],
  "filesToCreate": ["string (expected file paths)"],
  "scaffoldSkill": "string (optional)",
  "notes": "string (optional)",
  "passes": false
}

Note: New stories always start with passes: false.

Validation

Before writing, validate:

1. prd.json exists at scripts/ralph/prd.json
2. No duplicate IDs between existing and new stories
3. Required fields present for each new story (id, title, description, acceptanceCriteria)
4. testCriteria derived from acceptanceCriteria (for TDD)
5. testFiles specified for each story

Output

After successful merge:

Added 2 new stories to prd.json:

  notif-001: User Notifications (priority 4)
  export-001: Data Export (priority 5)

Existing stories preserved:
  - setup-001 (passes: true)
  - auth-001 (passes: true)
  - crud-001 (passes: false)

Total stories: 5 (2 completed, 3 pending)

Run ./scripts/ralph/ralph-once.sh to start the next story.

Error Cases

Examples

Add features from a file

/ralph-add docs/phase-2-features.md

Add a single story inline

/ralph-add --inline

# Then describe:
# "Add a notifications feature where users get email alerts for new messages"

Check what would be added (dry run)

/ralph-add docs/new-features.md --dry-run

Self-Improvement

After this skill completes, run /retro-create to review the session for issues and improve this skill. This is automatic — do not skip it.
