Ralph Prompt Builder (Master Orchestrator)
Overview
Master skill for generating prompts optimized for the Ralph Wiggum autonomous loop technique. This orchestrator analyzes your task description and routes to the appropriate specialized generator:
| Task Type | Generator | Best For |
|---|---|---|
| Single focused task | ralph-prompt-single-task |
Bug fixes, single features, refactoring |
| Multiple related tasks | ralph-prompt-multi-task |
CRUD, multi-step features, migrations |
| Complete project | ralph-prompt-project |
Greenfield apps, libraries, tools |
| Research/Analysis | ralph-prompt-research |
Audits, planning, investigations |
Quick Start
Generate any Ralph prompt:
Use ralph-prompt-builder to create a prompt for: [describe your task]
Example:
Use ralph-prompt-builder to create a prompt for: Implementing user authentication with JWT for our Express API
The skill will:
- Classify your task
- Route to the appropriate generator
- Guide you through required inputs
- Output a ready-to-use Ralph prompt
Task Classification
How Tasks Are Classified
| Indicators | Classification | Generator |
|---|---|---|
| Fix, repair, single change, one module | Single Task | ralph-prompt-single-task |
| Multiple features, CRUD, several endpoints | Multi-Task | ralph-prompt-multi-task |
| Build from scratch, new app, create tool | Project | ralph-prompt-project |
| Analyze, audit, compare, plan, investigate | Research | ralph-prompt-research |
Classification Questions
To classify your task, consider:
-
Is this creating something new from scratch or modifying existing code?
- New from scratch → Project or Multi-Task
- Modifying existing → Single Task or Multi-Task
-
How many distinct deliverables?
- One deliverable → Single Task
- 2-5 related deliverables → Multi-Task
- Complete application/tool → Project
- Analysis document → Research
-
Does it involve investigation before action?
- Yes, research required → Research
- No, implementation focus → Single/Multi/Project
-
What's the completion criteria?
- Tests pass → Single Task
- Multiple features working → Multi-Task
- Complete app running → Project
- Document produced → Research

Workflow
Step 1: Describe Your Task
Provide a description including:
- What needs to be done
- What technology/context
- Any specific requirements
- Desired outcome
Template:
Task: [What you want to accomplish]
Context: [Relevant background - tech stack, existing code, etc.]
Requirements: [Specific requirements or constraints]
Outcome: [What success looks like]
Step 2: Review Classification
The orchestrator will classify your task and explain why:
CLASSIFICATION: [Task Type]
REASONING: [Why this classification]
GENERATOR: ralph-prompt-[type]
Does this classification look correct? If not, specify your preferred type.
Step 3: Provide Generator Inputs
Each generator requires specific inputs:
Single Task:
- Task description
- Success criteria (how to verify)
- Completion promise text
Multi-Task:
- List of tasks
- Dependencies between tasks
- Final completion promise
Project:
- Project description
- Tech stack
- Feature list
- Completion promise
Research:
- Research objective
- Scope (in/out)
- Deliverable format
- Completion promise
Step 4: Generate & Review
The appropriate generator creates the prompt. Review and customize:
- Verify requirements are complete
- Check verification commands are correct
- Confirm completion criteria match your needs
- Adjust max-iterations recommendation
Step 5: Execute with Ralph
/ralph-wiggum:ralph-loop "[generated prompt]" --completion-promise "[YOUR_PROMISE]" --max-iterations [recommended]

Common Patterns
Choosing a Completion Promise
Good promises are:
- Specific to the task
- Verifiable (you can check if it's true)
- Action-oriented
Examples:
| Task Type | Good Promise | Why |
|---|---|---|
| Bug fix | AUTH_FIX_COMPLETE |
Specific to what was fixed |
| CRUD | PRODUCT_CRUD_DONE |
Names the resource |
| Project | TODO_API_V1_COMPLETE |
Identifies the project |
| Research | SECURITY_AUDIT_DELIVERED |
References deliverable |
The Ralph Philosophy
The Ralph Wiggum technique is built on a key insight: failures are deterministic and fixable.
- Deterministically bad: When prompts fail, they fail in predictable ways
- Fixable through iteration: Each failure provides data to improve
- Prompt tuning > tool changing: Fix failures by improving the prompt, not switching approaches
This means: Don't fear failures. They're expected and correctable. The loop will iterate until success.
Setting Max Iterations
Base recommendations by complexity:
| Complexity | Single Task | Multi-Task | Project | Research |
|---|---|---|---|---|
| Simple | 15 | 35 | 60 | 30 |
| Medium | 25 | 50 | 100 | 50 |
| Complex | 35 | 70 | 150 | 80 |
| Very Complex | - | 100 | 200 | 100 |
Adjust based on:
- Familiarity with codebase (-20%)
- External dependencies (+30%)
- Unclear requirements (+50%)
- Comprehensive testing needed (+25%)
Splitting Large Tasks
If task feels too large, consider splitting:
Project → Multiple Projects:
Instead of: "Build complete e-commerce platform"
Split into:
1. Project: User authentication service
2. Project: Product catalog API
3. Project: Shopping cart service
4. Project: Order processing service
Multi-Task → Separate Multi-Tasks:
Instead of: "Build full admin dashboard"
Split into:
1. Multi-Task: User management (CRUD + roles)
2. Multi-Task: Analytics dashboard
3. Multi-Task: Settings panel
Troubleshooting
Task Won't Complete
Symptoms: Hitting max iterations without completion
Causes and fixes:
- Scope too large → Split into smaller tasks
- Unclear criteria → Make success criteria more specific
- External dependencies → Document or mock dependencies
- Infinite tests → Check for flaky tests
Wrong Generator Selected
Fix: Specify the generator explicitly:
Use ralph-prompt-single-task (not multi-task) for: [task]
Prompt Too Vague
Fix: Ensure your input includes:
- Specific files/modules affected
- Actual test commands
- Concrete success criteria
- Technology context
Integration with Ralph Loop
After generating a prompt:
# Copy the generated prompt to a file or use directly
/ralph-wiggum:ralph-loop "[YOUR_GENERATED_PROMPT]" \
--completion-promise "YOUR_PROMISE" \
--max-iterations 50
# Monitor progress
head -10 .claude/ralph-loop.local.md
# Cancel if needed
/ralph-wiggum:cancel-ralph
Best Practices
DO:
- Start with the right generator for your task type
- Provide complete context and requirements
- Include specific verification commands
- Set appropriate max-iterations for complexity
- Review generated prompts before running
DON'T:
- Use vague task descriptions
- Skip the classification step
- Ignore the "If Stuck" guidance in generated prompts
- Set max-iterations too low (iterations are normal)
- Expect first-try perfection—Ralph embraces iteration
