Supports Next.js, Python, FastAPI, and GPU workloads with Ralph Wiggum methodology adapted for OpenClaw.

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/
    β”œβ”€β”€ IMPLEMENTATION_PLAN.md     # Shared state, updated each iteration
    β”œβ”€β”€ AGENTS.md                  # Build/test/lint commands (~60 lines)
    β”œβ”€β”€ specs/                     # Requirements (one file per topic)
    β”‚   β”œβ”€β”€ topic-a.md
    β”‚   └── topic-b.md
    β”œβ”€β”€ 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"?

  • βœ… "User authentication with JWT and session management"
  • ❌ "Auth, profiles, and billing" β†’ 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:

  • βœ… All IMPLEMENTATION_PLAN.md tasks completed
  • βœ… All acceptance criteria met
  • βœ… Tests passing, no blocking issues
  • ⚠️ Max iterations reached (configure limit)
  • πŸ›‘ 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;

    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 βœ…

    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
  • Appendix: Hall of Failures

    Common anti-patterns observed:

    | Anti-Pattern | Consequence | Prevention | |--------------|-------------|------------| | No progress logging | Parent agent cannot determine status | Mandatory PROGRESS.md | | Silent failure | Work lost, time wasted | Explicit error logging | | Overlapping sessions | File conflicts, corrupt state | Check/cleanup before spawn | | Path assumptions | Wrong directory, wrong files | Explicit verification | | No completion signal | Parent waits indefinitely | Clear COMPLETE status | | Infinite iteration | Resource waste, no progress | Time limits + blockers | | Complex initial prompts | Sub-agent never starts (empty session logs) | SIMPLIFY instructions |

    NEW: Session Initialization Best Practices (2025-02-07)

    Problem: Sub-agents spawn but don't execute

    Evidence: Empty session logs (2 bytes), no tool calls, 0 tokens used

    Root Causes

    1. Instructions too complex - Overwhelms isolated session initialization 2. No clear execution trigger - Agent doesn't know to start 3. Branching logic - "If X do Y, if Z do W" confuses task selection 4. Multiple files mentioned - Can't decide which to start with

    Fix: SIMPLIFIED Ralph Task Template

    ## Task: [ONE specific thing]

    File: exact/path/to/file.ts What: Exact description of change Validate: Exact command to run Then: Update PROGRESS.md and exit

    Rules

    1. Do NOT look at other files 2. Do NOT "check first" 3. Make the change, validate, exit

    BEFORE (Bad - causes stalls):

    Fix all TypeScript errors across these files:
    
  • lib/db.ts has 2 errors
  • lib/proposal-service.ts has 5 errors
  • route.ts has errors
  • Check which ones to fix first, then...

    AFTER (Good - executes):

    Fix lib/db.ts line 27:
    Change: PoolClient to pg.PoolClient
    Validate: npm run typecheck
    Exit immediately after
    

    CRITICAL: Single File Rule

    Each Ralph iteration gets ONE file. Not "all errors", not "check then decide". ONE file, ONE change, validate, exit.

    CRITICAL: Update PROGRESS.md

    MANDATORY: After EVERY iteration, update PROGRESS.md with:
    ## Iteration [N] - [Timestamp]

    Status: Complete βœ… | Blocked β›” | Failed ❌

    What Was Done

  • [Specific changes made]
  • Validation

  • [Test/lint/typecheck results]
  • Next Step

  • [What should happen next]
  • Why this matters: Cron job reads PROGRESS.md for status updates. If not updated, status appears stale/repetitive.

    Debugging Ralph Stalls

    If Ralph stalls: 1. Check session logs (should show tool calls within 60s) 2. If empty after spawn β†’ instructions too complex 3. Reduce: ONE file, ONE line number, ONE change 4. Shorter timeout forces smaller tasks (300s not 600s)

    Fixing Stale Status Reports

    If cron reports same status repeatedly: 1. Check PROGRESS.md was updated by sub-agent 2. If not updated β†’ sub-agent skipped documentation step 3. Update skill: Add "MANDATORY PROGRESS.md update" to prompt 4. Manual fix: Update PROGRESS.md to reflect actual state

    Summary

    Ralph works when: Single file focus + explicit change + validate + exit Ralph stalls when: Complex decisions + multiple files + conditional logic
