Orchestration SKILLz Template

Build automation systems using layered, composable test modules that snap together like LEGO blocks.

First Principles

1. Layer Independence: Each layer tests one capability in isolation
2. Progressive Complexity: L0 → L1 → L2 → L3 builds up to full chain
3. Snap Together: Full chain combines all layers
4. Occam's Build: Start simple, add layers only when needed

Layer Architecture

L0: Entry       → Navigate, find target (e.g., find unlisted videos)
L1: Filter      → Apply filters/constraints (e.g., unlisted filter)
L2: Edit        → Modify/interact with target (e.g., enhance metadata)
L3: Execute     → Complete action (e.g., schedule, publish)
Full Chain      → L0 + L1 + L2 + L3 snapped together

Implementation Pattern

1. Build Each Layer Independently

# test_layer0_entry.py
def test_layer0():
    """L0: Can we navigate to the target?"""
    driver = connect_browser()
    result = navigate_to_target(driver)
    assert result.success, "L0 failed: could not reach target"

2. Chain Layers Together

# test_full_chain.py
def test_full_chain():
    """Full chain: L0 → L1 → L2 → L3"""
    driver = connect_browser()
    
    # L0: Entry
    navigate_to_target(driver)
    
    # L1: Filter
    apply_filters(driver)
    
    # L2: Edit
    modify_target(driver)
    
    # L3: Execute
    complete_action(driver)

3. Create Menu with Layer Access

def show_menu():
    print("1. Run Full Chain")
    print("2. Preview Only (DRY RUN)")
    print("D. Dev Tests (L0-L3)")

When to Use This Pattern

• Browser automation (Selenium/Playwright)
• Multi-step workflows (schedule, publish, moderate)
• API orchestration with validation gates
• Any system requiring incremental testing

Success Metrics

• Each layer passes independently
• Full chain completes without manual intervention
• 0102 can use simplified menu (dev tests hidden)
