Cascade Orchestrator (Enhanced)

Overview

Manages workflows (cascades) that coordinate multiple micro-skills into cohesive processes. This enhanced version integrates Codex sandbox iteration, multi-model routing, ruv-swarm coordination, and memory persistence across stages.

Philosophy: Composable Excellence

Complex capabilities emerge from composing simple, well-defined components.

Enhanced Capabilities:

• Codex Sandbox Iteration: Auto-fix failures in isolated environment (from audit-pipeline)
• Multi-Model Routing: Use Gemini/Codex based on stage requirements
• Swarm Coordination: Parallel execution via ruv-swarm MCP
• Memory Persistence: Maintain context across stages
• GitHub Integration: CI/CD pipeline automation

Key Principles:

1. Separation of concerns (micro-skills execute, cascades coordinate)
2. Reusability through composition
3. Flexible orchestration patterns
4. Declarative workflow definition
5. Intelligent model selection

Cascade Architecture (Enhanced)

Definition Layer

Extended Stage Types:

stages:

Enhanced Data Flow:

data_flow:
  - stage_output: previous stage results
  - shared_memory: persistent across stages
  - multi_model_context: AI-specific formatting
  - codex_sandbox_state: isolated test environment

Advanced Error Handling:

error_handling:
  - retry_with_backoff
  - fallback_to_alternative
  - codex_auto_fix        # NEW: Auto-fix via Codex
  - model_switching       # NEW: Try different AI
  - swarm_recovery        # NEW: Redistribute tasks

Execution Engine (Enhanced)

Stage Scheduling with AI Selection:

for stage in cascade.stages:
    if stage.type == "codex-sandbox":
        execute_with_codex_iteration(stage)
    elif stage.type == "multi-model":
        model = select_optimal_model(stage.task)
        execute_on_model(stage, model)
    elif stage.type == "swarm-parallel":
        execute_via_ruv_swarm(stage)
    else:
        execute_standard(stage)

Codex Sandbox Iteration Loop:

def execute_with_codex_iteration(stage):
    """
    From audit-pipeline Phase 2: functionality-audit pattern
    """
    results = execute_tests(stage.tests)

    for test in failed_tests(results):
        iteration = 0
        max_iterations = 5

        while test.failed and iteration < max_iterations:
            # Spawn Codex in sandbox
            fix = spawn_codex_auto(
                task=f"Fix test failure: {test.error}",
                sandbox=True,
                context=test.context
            )

            # Re-test
            test.result = rerun_test(test)
            iteration += 1

            if test.passed:
                apply_fix_to_main(fix)
                break

        if still_failed(test):
            escalate_to_user(test)

    return aggregate_results(results)

Multi-Model Routing:

def select_optimal_model(task):
    """
    Route to best AI based on task characteristics
    """
    if task.requires_large_context:
        return "gemini-megacontext"  # 1M tokens
    elif task.needs_current_info:
        return "gemini-search"        # Web grounding
    elif task.needs_visual_output:
        return "gemini-media"          # Imagen/Veo
    elif task.needs_rapid_prototype:
        return "codex-auto"            # Full Auto
    elif task.needs_alternative_view:
        return "codex-reasoning"       # GPT-5-Codex
    else:
        return "claude"                # Best overall

Enhanced Cascade Patterns

Pattern 1: Linear Pipeline with Multi-Model

cascade:
  name: enhanced-data-pipeline
  stages:
    - stage: extract
      model: auto-select
      skill: extract-data

    - stage: validate
      model: auto-select
      skill: validate-data
      error_handling:
        strategy: codex-auto-fix  # NEW

    - stage: transform
      model: codex-auto           # Fast prototyping
      skill: transform-data

    - stage: report
      model: gemini-media         # Generate visuals
      skill: generate-report

Pattern 2: Parallel Fan-Out with Swarm

cascade:
  name: code-quality-swarm
  stages:
    - stage: quality-checks
      type: swarm-parallel        # NEW: Via ruv-swarm
      skills:
        - lint-code
        - security-scan
        - complexity-analysis
        - test-coverage
      swarm_config:
        topology: mesh
        max_agents: 4
        strategy: balanced

    - stage: aggregate
      skill: merge-quality-reports

Pattern 3: Codex Sandbox Iteration

cascade:
  name: test-and-fix
  stages:
    - stage: functionality-audit
      type: codex-sandbox         # NEW
      test_suite: comprehensive
      codex_config:
        mode: full-auto
        max_iterations: 5
        sandbox: true
      error_recovery:
        auto_fix: true
        escalate_after: 5

    - stage: validate-fixes
      skill: regression-tests

Pattern 4: Conditional with Model Switching

cascade:
  name: adaptive-workflow
  stages:
    - stage: analyze
      model: gemini-megacontext   # Large context
      skill: analyze-codebase

    - stage: decide
      type: conditional
      condition: ${analyze.quality_score}
      branches:
        high_quality:
          model: codex-auto       # Fast path
          skill: deploy-fast
        low_quality:
          model: multi-model      # Comprehensive path
          cascade: deep-quality-audit

Pattern 5: Iterative with Memory

cascade:
  name: iterative-refinement
  stages:
    - stage: refactor
      model: auto-select
      skill: refactor-code
      memory: persistent          # NEW

    - stage: check-quality
      skill: quality-metrics

    - stage: repeat-decision
      type: conditional
      condition: ${quality < threshold}
      repeat: refactor            # Loop back
      max_iterations: 3
      memory_shared: true         # Context persists

Creating Enhanced Cascades

Step 1: Define with AI Considerations

Identify Model Requirements:

For each stage, determine:
- Large context needed? → Gemini
- Current web info needed? → Gemini Search
- Visual output needed? → Gemini Media
- Rapid prototyping needed? → Codex
- Testing with auto-fix? → Codex Sandbox
- Best overall reasoning? → Claude

Step 2: Design with Swarm Parallelism

When to Use Swarm:

• Multiple independent tasks
• Resource-intensive operations
• Need load balancing
• Want fault tolerance

Swarm Configuration:

swarm_config:
  topology: mesh | hierarchical | star
  max_agents: number
  strategy: balanced | specialized | adaptive
  memory_shared: true | false

Step 3: Add Codex Iteration for Quality

Pattern from audit-pipeline:

stages:
  - type: codex-sandbox
    tests: ${test_suite}
    fix_strategy:
      auto_fix: true
      max_iterations: 5
      sandbox_isolated: true
      network_disabled: true
      regression_check: true

Step 4: Enable Memory Persistence

Shared Memory Across Stages:

memory:
  persistence: enabled
  scope: cascade | global
  storage: mcp__ruv-swarm__memory
  keys:
    - analysis_results
    - intermediate_outputs
    - learned_patterns
