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

Locate or create state file: {project}/.ralph/state.json
Locate or create categories file: {project}/.ralph/categories.json
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:

Write failing test first
Implement minimal fix
Verify test passes
Update state

Phase 4: Category Evolution

After each iteration:

Merge new discoveries
Recalculate scores
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

Review Styles

Code Quality

| Style | Focus | |-------|-------| | NITPICKER | Formatting, naming, tiny inconsistencies | | REFACTORER | Duplication, abstraction opportunities | | DRY_ENFORCER | Copy-paste code, repeated patterns | | TYPE_ZEALOT | Type safety, any usage, casting | | SOLID_ADHERENT | SOLID principle violations | | API_PURIST | Interface design, contracts, signatures |

Reliability

| Style | Focus | |-------|-------| | DEBUGGER | Logic errors, off-by-one, wrong operators | | EDGE_CASE_HUNTER | Boundary conditions, null/undefined | | ERROR_HANDLER | Missing try/catch, unhandled promises | | STATE_MACHINE_ANALYST | Invalid state transitions | | CONCURRENCY_EXPERT | Race conditions, async bugs | | MEMORY_LEAK_HUNTER | Listeners not removed, growing arrays |

Performance

| Style | Focus | |-------|-------| | PERFORMANCE_HAWK | O(n²), unnecessary renders, hot paths | | ALLOCATION_AUDITOR | Object churn, GC pressure | | RENDER_OPTIMIZER | DOM thrashing, layout thrashing |

Security

| Style | Focus | |-------|-------| | SECURITY_AUDITOR | XSS, injection, unsafe operations | | INPUT_VALIDATOR | Unsanitized user input |

Architecture

| Style | Focus | |-------|-------| | ARCHITECT | Coupling, cohesion, separation of concerns | | DEPENDENCY_AUDITOR | Circular deps, tight coupling | | LAYER_GUARDIAN | Layer violations, wrong abstractions |

Testing

| Style | Focus | |-------|-------| | TEST_SKEPTIC | Coverage gaps, weak assertions | | MUTATION_TESTER | Tests that always pass | | INTEGRATION_ANALYST | Unit vs integration gaps |

Game-Specific

| Style | Focus | |-------|-------| | DIABLO_VETERAN | ARPG conventions, loot, skills, combat feel | | STARCRAFT_FAN | Faction identity, unit feel, SC universe | | GAME_FEEL_EXPERT | Juice, polish, responsiveness | | BALANCE_DESIGNER | Numbers, progression, fairness | | PLAYER_PSYCHOLOGY | Motivation, reward loops | | SPEEDRUNNER | Exploits, sequence breaks | | COMPLETIONIST | Missing edge cases in content | | FIRST_TIME_USER | Onboarding, confusion points |

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:

Full test suite run
TypeScript strict mode check
Build production bundle
Verify game loads and plays
Generate completion report
Output: {COMPLETION_PROMISE} achieved
