Ralph Wiggum v2 - Autonomous TDD Development Loop

Ralph Wiggum v2 - Autonomous TDD Development Loop

Quick Start

/​ralph-wiggum-v2:ralph-loop --project "diablo-starcraft" --completion-promise "DIABLO_STARCRAFT_COMPLETE"

Overview

Autonomous TDD development loop that uses parallel agent swarms to review code, discover issues, and fix them with test-first methodology until convergence criteria are met.

Workflow

Phase 1: Discovery & Initialization

1. Locate or create state file: {project}/​.ralph/​state.json
2. Locate or create categories file: {project}/​.ralph/​categories.json
3. Bootstrap categories from codebase structure if empty

Phase 2: Parallel Agent Review Swarm

Spawn 3-5 parallel agents with:

• Random category (weighted toward lowest scores)
• Random subcategory within that category
• Random review style (never same as last 3 used)
• Unique focus area (no overlap between agents)

Phase 3: TDD Implementation Cycle

For each finding:

1. Write failing test first
2. Implement minimal fix
3. Verify test passes
4. Update state

Phase 4: Category Evolution

After each iteration:

1. Merge new discoveries
2. Recalculate scores
3. Meta-review (every 5 iterations)

Phase 5: Convergence Detection

Complete when:

• 10 consecutive clean iterations
• All category scores >= 95/​100
• All tests passing
• Game runs without crashes

Hard Requirements

• PLAYABLE_LOCAL - Runs in browser, playable start-to-finish
• TDD_ENFORCED - No fix without failing test first
• ZERO_CRASHES - No unhandled exceptions in any path
• ALL_TESTS_PASS - 100% test suite green
• SCORES_95_PLUS - Every category at 95+/​100
• CLEAN_CONVERGENCE - 10 consecutive clean iterations

---

Iteration Loop

LOOP:
  1. Load state from .ralph/​state.json
  2. Load categories from .ralph/​categories.json
  3. Increment iteration counter
  4. Select 3-5 lowest-scoring categories for review
  5. Spawn parallel review agents (use Task tool)
  6. Collect findings from all agents
  7. Sort findings by severity (critical → major → minor)
  8. TDD fix each finding:
     a. Write failing test
     b. Implement minimal fix
     c. Verify test passes
     d. Run full test suite
  9. Update scores and state
  10. Check convergence criteria:
      - All agents returned cleanReview: true?
      - No critical/​major findings?
      - All tests passing?
      - No new categories discovered?
  11. IF clean: consecutiveCleanIterations++
      IF dirty: consecutiveCleanIterations = 0
  12. IF consecutiveCleanIterations >= 10 AND all scores >= 95:
      → CONVERGED: Run final verification
      ELSE: → Continue loop

---

Final Verification

When convergence criteria met:

1. Full test suite run
2. TypeScript strict mode check
3. Build production bundle
4. Verify game loads and plays
5. Generate completion report
6. Output: {COMPLETION_PROMISE} achieved
