Ralph Mode - Autonomous Development Loops

Ralph Mode implements the Ralph Wiggum technique adapted for OpenClaw: autonomous task completion through continuous iteration with backpressure gates, completion criteria, and structured planning.

When to Use

Use Ralph Mode when:

• Building features that require multiple iterations and refinement
• Working on complex projects with acceptance criteria to validate
• Need automated testing, linting, or typecheck gates
• Want to track progress across many iterations systematically
• Prefer autonomous loops over manual turn-by-turn guidance

Core Principles

Three-Phase Workflow

Phase 1: Requirements Definition

• Document specs in specs/ (one file per topic of concern)
• Define acceptance criteria (observable, verifiable outcomes)
• Create implementation plan with prioritized tasks

Phase 2: Planning

• Gap analysis: compare specs against existing code
• Generate IMPLEMENTATION_PLAN.md with prioritized tasks
• No implementation during this phase

Phase 3: Building (Iterative)

• Pick one task from plan per iteration
• Implement, validate, update plan, commit
• Continue until all tasks complete or criteria met

Backpressure Gates

Reject incomplete work automatically through validation:

Programmatic Gates (Always use these):

• Tests: [test command] - Must pass before committing
• Typecheck: [typecheck command] - Catch type errors early
• Lint: [lint command] - Enforce code quality
• Build: [build command] - Verify integration

Subjective Gates (Use for UX, design, quality):

• LLM-as-judge reviews for tone, aesthetics, usability
• Binary pass/fail - converges through iteration
• Only add after programmatic gates work reliably

Context Efficiency

• One task per iteration = fresh context each time
• Spawn sub-agents for exploration, not main context
• Lean prompts = smart zone (~40-60% utilization)
• Plans are disposable - regenerate cheap vs. salvage

File Structure

Create this structure for each Ralph Mode project:

project-root/
├── IMPLEMENTATION_PLAN.md     # Shared state, updated each iteration
├── AGENTS.md                  # Build/test/lint commands (~60 lines)
├── specs/                     # Requirements (one file per topic)
│   ├── topic-a.md
│   └── topic-b.md
├── src/                        # Application code
└── src/lib/                    # Shared utilities

IMPLEMENTATION_PLAN.md

Priority task list - single source of truth. Format:

# Implementation Plan

## In Progress
- [ ] Task name (iteration N)
  - Notes: discoveries, bugs, blockers

## Completed
- [x] Task name (iteration N)

## Backlog
- [ ] Future task

Topic Scope Test

Can you describe the topic in one sentence without "and"?

• ✅ "User authentication with JWT and session management"
• ❌ "Auth, profiles, and billing" → 3 topics

AGENTS.md - Operational Guide

Succinct guide for running the project. Keep under 60 lines:

# Project Operations

## Build Commands
npm run dev      # Development server
npm run build     # Production build

## Validation
npm run test      # All tests
npm run lint      # ESLint
npm run typecheck  # TypeScript
npm run e2e       # E2E tests

## Operational Notes
- Tests must pass before committing
- Typecheck failures block commits
- Use existing utilities from src/lib over ad-hoc copies

Hats (Personas)

Specialized roles for different tasks:

Hat: Architect (@architect)

• High-level design, data modeling, API contracts
• Focus: patterns, scalability, maintainability

Hat: Implementer (@implementer)

• Write code, implement features, fix bugs
• Focus: correctness, performance, test coverage

Hat: Tester (@tester)

• Test authoring, validation, edge cases
• Focus: coverage, reliability, reproducibility

Hat: Reviewer (@reviewer)

• Code reviews, PR feedback, quality assessment
• Focus: style, readability, adherence to specs

Usage:

"Spawn a sub-agent with @architect hat to design the data model"

Loop Mechanics

Outer Loop (You coordinate)

Your job as main agent: engineer setup, observe, course-correct.

1. Don't allocate work to main context - Spawn sub-agents
2. Let Ralph Ralph - LLM will self-identify, self-correct
3. Use protection - Sandbox is your security boundary
4. Plan is disposable - Regenerate when wrong/stale
5. Move outside the loop - Sit and watch, don't micromanage

Inner Loop (Sub-agent executes)

Each sub-agent iteration:

1. Study - Read plan, specs, relevant code
2. Select - Pick most important uncompleted task
3. Implement - Write code, one task only
4. Validate - Run tests, lint, typecheck (backpressure)
5. Update - Mark task done, note discoveries, commit
6. Exit - Next iteration starts fresh

Stopping Conditions

Loop ends when:

• ✅ All IMPLEMENTATION_PLAN.md tasks completed
• ✅ All acceptance criteria met
• ✅ Tests passing, no blocking issues
• ⚠️ Max iterations reached (configure limit)
• 🛑 Manual stop (Ctrl+C)

Completion Criteria

Define success upfront - avoid "seems done" ambiguity.

Programmatic (Measurable)

• All tests pass: [test_command] returns 0
• Typecheck passes: No TypeScript errors
• Build succeeds: Production bundle created
• Coverage threshold: e.g., 80%+

Subjective (LLM-as-Judge)

For quality criteria that resist automation:

## Completion Check - UX Quality
Criteria: Navigation is intuitive, primary actions are discoverable
Test: User can complete core flow without confusion

## Completion Check - Design Quality
Criteria: Visual hierarchy is clear, brand consistency maintained
Test: Layout follows established patterns

Run LLM-as-judge sub-agent for binary pass/fail.

Quick Start Command

Start a Ralph Mode session:

"Start Ralph Mode for my project at ~/projects/my-app. I want to implement user authentication with JWT.

I will:

1. Create IMPLEMENTATION_PLAN.md with prioritized tasks
2. Spawn sub-agents for iterative implementation
3. Apply backpressure gates (test, lint, typecheck)
4. Track progress and announce completion

Operational Learnings

When Ralph patterns emerge, update AGENTS.md:

## Discovered Patterns

- When adding API routes, also add to OpenAPI spec
- Use existing db utilities from src/lib/db over direct calls
- Test files must be co-located with implementation

Escape Hatches

When trajectory goes wrong:

• Ctrl+C - Stop loop immediately
• Regenerate plan - "Discard IMPLEMENTATION_PLAN.md and re-plan"
• Reset - "Git reset to last known good state"
• Scope down - Create smaller scoped plan for specific work

Advanced: LLM-as-Judge Fixture

For subjective criteria (tone, aesthetics, UX):

Create src/lib/llm-review.ts:

interface ReviewResult {
  pass: boolean;
  feedback?: string;
}

async function createReview(config: {
  criteria: string;
  artifact: string; // text or screenshot path
}): Promise<ReviewResult>;

Sub-agents discover and use this pattern for binary pass/fail checks.

Critical Operational Requirements

Based on empirical usage, enforce these practices to avoid silent failures:

1. Mandatory Progress Logging

Ralph MUST write to PROGRESS.md after EVERY iteration. This is non-negotiable.

Create PROGRESS.md in project root at start:

# Ralph: [Task Name]

## Iteration [N] - [Timestamp]

### Status
- [ ] In Progress | [ ] Blocked | [ ] Complete

### What Was Done
- [Item 1]
- [Item 2]

### Blockers
- None | [Description]

### Next Step
[Specific next task from IMPLEMENTATION_PLAN.md]

### Files Changed
- `path/to/file.ts` - [brief description]

Why: External observers (parent agents, crons, humans) can tail one file instead of scanning directories or inferring state from session logs.

2. Session Isolation & Cleanup

Before spawning a new Ralph session:

• Check for existing Ralph sub-agents via sessions_list
• Kill or verify completion of previous sessions
• Do NOT spawn overlapping Ralph sessions on same codebase

Anti-pattern: Spawning Ralph v2 while v1 is still running = file conflicts, race conditions, lost work.

3. Explicit Path Verification

Never assume directory structure. At start of each iteration:

// Verify current working directory
const cwd = process.cwd();
console.log(`Working in: ${cwd}`);

// Verify expected paths exist
if (!fs.existsSync('./src/app')) {
  console.error('Expected ./src/app, found:', fs.readdirSync('.'));
  // Adapt or fail explicitly
}

Why: Ralph may be spawned from different contexts with different working directories.

4. Completion Signal Protocol

When done, Ralph MUST:

1. Write final PROGRESS.md with "## Status: COMPLETE"
2. List all created/modified files
3. Exit cleanly (no hanging processes)

Example completion PROGRESS.md:

# Ralph: Influencer Detail Page

## Status: COMPLETE ✅

**Finished:** [ISO timestamp]

### Final Verification
- [x] TypeScript: Pass
- [x] Tests: Pass  
- [x] Build: Pass

### Files Created
- `src/app/feature/page.tsx`
- `src/app/api/feature/route.ts`

### Testing Instructions
1. Run: `npm run dev`
2. Visit: `http://localhost:3000/feature`
3. Verify: [specific checks]

5. Error Handling Requirements

If Ralph encounters unrecoverable errors:

1. Log to PROGRESS.md with "## Status: BLOCKED"
2. Describe blocker in detail
3. List attempted solutions
4. Exit cleanly (don't hang)

Do not silently fail. A Ralph that stops iterating with no progress log is indistinguishable from one still working.

6. Iteration Time Limits

Set explicit iteration timeouts:

## Operational Parameters
- Max iteration time: 10 minutes
- Total session timeout: 60 minutes
- If iteration exceeds limit: Log blocker, exit

Why: Prevents infinite loops on stuck tasks, allows parent agent to intervene.

Memory Updates

After each Ralph Mode session, document:

## [Date] Ralph Mode Session

**Project:** [project-name]
**Duration:** [iterations]
**Outcome:** success / partial / blocked
**Learnings:**
- What worked well
- What needs adjustment
- Patterns to add to AGENTS.md
