Ralph TUI - Create JSON Tasks
Converts PRDs to prd.json format for ralph-tui autonomous execution.
Note: This skill is bundled with ralph-tui's JSON tracker plugin. Future tracker plugins (Linear, GitHub Issues, etc.) will bundle their own task creation skills.
⚠️ CRITICAL: The output MUST be a FLAT JSON object with "name" and "userStories" at the ROOT level. DO NOT wrap content in a "prd" object or use "tasks" array. See "Schema Anti-Patterns" section below.
The Job
Take a PRD (markdown file or text) and create a prd.json file:
- Extract Quality Gates from the PRD's "Quality Gates" section
- Parse user stories from the PRD
- Append quality gates to each story's acceptance criteria
- Set up dependencies between stories
- Output ready for
ralph-tui run --prd <path>
Step 1: Extract Quality Gates
Look for the "Quality Gates" section in the PRD:
## Quality Gates
These commands must pass for every user story:
- `pnpm typecheck` - Type checking
- `pnpm lint` - Linting
For UI stories, also include:
- Verify in browser using dev-browser skill
Extract:
- Universal gates: Commands that apply to ALL stories (e.g.,
pnpm typecheck) - UI gates: Commands that apply only to UI stories (e.g., browser verification)
If no Quality Gates section exists: Ask the user what commands should pass, or use a sensible default like npm run typecheck.
Output Format
The JSON file MUST be a FLAT object at the root level:
{
"name": "[Project name from PRD or directory]",
"branchName": "ralph/[feature-name-kebab-case]",
"description": "[Feature description from PRD]",
"userStories": [
{
"id": "US-001",
"title": "[Story title]",
"description": "As a [user], I want [feature] so that [benefit]",
"acceptanceCriteria": [
"Criterion 1 from PRD",
"Criterion 2 from PRD",
"pnpm typecheck passes",
"pnpm lint passes"
],
"priority": 1,
"passes": false,
"notes": "",
"dependsOn": []
},
{
"id": "US-002",
"title": "[UI Story that depends on US-001]",
"description": "...",
"acceptanceCriteria": [
"...",
"pnpm typecheck passes",
"pnpm lint passes",
"Verify in browser using dev-browser skill"
],
"priority": 2,
"passes": false,
"notes": "",
"dependsOn": ["US-001"]
}
]
}
CRITICAL: Schema Anti-Patterns (DO NOT USE)
The following patterns are INVALID and will cause validation errors:
❌ WRONG: Wrapper object
{
"prd": {
"name": "...",
"userStories": [...]
}
}
This wraps everything in a "prd" object. DO NOT DO THIS. The "name" and "userStories" fields must be at the ROOT level.
❌ WRONG: Using "tasks" instead of "userStories"
{
"name": "...",
"tasks": [...]
}
The array is called "userStories", not "tasks".
❌ WRONG: Complex nested structures
{
"metadata": {...},
"overview": {...},
"migration_strategy": {
"phases": [...]
}
}
Even if the PRD describes phases/milestones/sprints, you MUST flatten these into a single "userStories" array.
❌ WRONG: Using "status" instead of "passes"
{
"userStories": [{
"id": "US-001",
"status": "open" // WRONG!
}]
}
Use "passes": false for incomplete stories, "passes": true for completed.
✅ CORRECT: Flat structure at root
{
"name": "Android Kotlin Migration",
"branchName": "ralph/kotlin-migration",
"userStories": [
{"id": "US-001", "title": "Create Scraper interface", "passes": false, "dependsOn": []},
{"id": "US-002", "title": "Implement WeebCentralScraper", "passes": false, "dependsOn": ["US-001"]}
]
}
Story Size: The #1 Rule
Each story must be completable in ONE ralph-tui iteration (~one agent context window).
Ralph-tui spawns a fresh agent instance per iteration with no memory of previous work. If a story is too big, the agent runs out of context before finishing.
Right-sized stories:
- Add a database column + migration
- Add a UI component to an existing page
- Update a server action with new logic
- Add a filter dropdown to a list
Too big (split these):
- "Build the entire dashboard" → Split into: schema, queries, UI components, filters
- "Add authentication" → Split into: schema, middleware, login UI, session handling
- "Refactor the API" → Split into one story per endpoint or pattern
Rule of thumb: If you can't describe the change in 2-3 sentences, it's too big.
Dependencies with dependsOn
Use the dependsOn array to specify which stories must complete first:
{
"id": "US-002",
"title": "Create API endpoints",
"dependsOn": ["US-001"], // Won't be selected until US-001 passes
...
}
Ralph-tui will:
- Show US-002 as "blocked" until US-001 completes
- Never select US-002 for execution while US-001 is open
- Include "Prerequisites: US-001" in the prompt when working on US-002
Correct dependency order:
- Schema/database changes (no dependencies)
- Backend logic (depends on schema)
- UI components (depends on backend)
- Integration/polish (depends on UI)
Acceptance Criteria: Quality Gates + Story-Specific
Each story's acceptance criteria should include:
- Story-specific criteria from the PRD (what this story accomplishes)
- Quality gates from the PRD's Quality Gates section (appended at the end)
Good criteria (verifiable):
- "Add
statuscolumn to tasks table with default 'open'" - "Filter dropdown has options: All, Open, Closed"
- "Clicking delete shows confirmation dialog"
Bad criteria (vague):
- ❌ "Works correctly"
- ❌ "User can do X easily"
- ❌ "Good UX"
- ❌ "Handles edge cases"
Conversion Rules
- Extract Quality Gates from PRD first
- Each user story → one JSON entry
- IDs: Sequential (US-001, US-002, etc.)
- Priority: Based on dependency order (1 = highest)
- dependsOn: Array of story IDs this story requires
- All stories:
passes: falseand emptynotes - branchName: Derive from feature name, kebab-case, prefixed with
ralph/ - Acceptance criteria: Story criteria + quality gates appended
- UI stories: Also append UI-specific gates (browser verification)
Output Location
Default: ./tasks/prd.json (alongside the PRD markdown files)
This keeps all PRD-related files together in the tasks/ directory.
Or specify a different path - ralph-tui will use it with:
ralph-tui run --prd ./path/to/prd.json
Example
Input PRD:
# PRD: Task Priority System
Add priority levels to tasks.
## Quality Gates
These commands must pass for every user story:
- `pnpm typecheck` - Type checking
- `pnpm lint` - Linting
For UI stories, also include:
- Verify in browser using dev-browser skill

Running with ralph-tui
After creating prd.json:
ralph-tui run --prd ./tasks/prd.json
Ralph-tui will:
- Load stories from prd.json
- Select the highest-priority story with
passes: falseand no blocking dependencies - Generate a prompt with story details + acceptance criteria
- Run the agent to implement the story
- Mark
passes: trueon completion - Repeat until all stories pass
Checklist Before Saving
- Extracted Quality Gates from PRD (or asked user if missing)
- Each story completable in one iteration
- Stories ordered by dependency (schema → backend → UI)
-
dependsOncorrectly set for each story - Quality gates appended to every story's acceptance criteria
- UI stories have browser verification (if specified in Quality Gates)
- Acceptance criteria are verifiable (not vague)
- No circular dependencies
