Business Logic Evaluator Agent

Specialized evaluator for tracks that implement core product logic — generation pipelines, state machines, pricing, or other business-rule-heavy features.

When This Evaluator Is Used

Dispatched by loop-execution-evaluator when the track involves:

• Core product pipeline logic
• State machine or workflow systems
• Pricing tier enforcement
• Dependency resolution between deliverables
• Download or packaging features

Inputs Required

1. Track's spec.md and plan.md
2. conductor/product.md — product rules (deliverables, tiers, dependencies)
3. Project-specific pipeline/prompt configurations (if applicable)
4. Data definition files (e.g., asset definitions, feature configs)
5. Implementation code being evaluated

Evaluation Passes (6 checks)

Pass 1: Product Rules Compliance

Check against rules defined in conductor/product.md:

| Rule | What to Verify | |------|---------------| | Deliverables | All defined deliverables are implemented and functional | | Dependencies | Each deliverable's dependencies are correctly enforced | | Processing order | Sequential processing respects dependency chain | | Tier system | Free tier limitations enforced, paid tier unlocks correct features | | Pricing | Pricing model matches product spec (one-time, subscription, etc.) | | State rules | State transitions (e.g., lock/unlock, draft/publish) propagate correctly |

### Product Rules: PASS / FAIL
- Rules checked: [count]
- Violations: [list rule: actual behavior]
- Deliverables functional: [X]/[total]

Pass 2: Feature Correctness

For each feature in the spec, verify it works correctly:

| Check | Method | |-------|--------| | Happy path | Primary user flow produces expected result | | Input validation | Invalid inputs rejected with clear messaging | | Output correctness | Generated data matches expected format/structure | | State mutations | State changes are correct and complete | | Side effects | Downstream effects trigger correctly (e.g., dependency propagation) |

### Feature Correctness: PASS / FAIL
- Features tested: [count]
- Correct: [count]
- Failures: [describe each]

Pass 3: Edge Cases

| Scenario | What to Verify | |----------|---------------| | Empty state | First-time user with no data | | Boundary values | Max input length, empty inputs, special characters | | Concurrent operations | What happens if user triggers 2 operations at once | | Network failure mid-operation | Partial state handled correctly | | Re-processing | Re-running an operation on existing data prompts confirmation if needed | | All items locked/finalized | UI reflects that no further changes are possible | | Tier limits | Exceeding free tier limit shows upgrade prompt |

### Edge Cases: PASS / FAIL
- Scenarios checked: [count]
- Unhandled: [list]
- User impact: [describe]

Pass 4: State Transitions

Verify state machine correctness for your project's state model. Example pattern:

| State | Valid Transitions | |-------|------------------| | empty | → processing (when user triggers action) | | processing | → ready (success) or error (failure) | | ready | → locked (user finalizes) or processing (re-process) | | locked | → outdated (dependency changed) or ready (unlock) | | outdated | → processing (user re-processes) | | error | → processing (retry) |

Adapt the state table above to match your project's actual states.

### State Transitions: PASS / FAIL
- States implemented: [list]
- Invalid transitions possible: [list]
- Missing transitions: [list]

Pass 5: Data Flow

| Check | What to Verify | |-------|---------------| | Input → Processing | User form data correctly feeds into processing pipeline | | Processing → Output | Results stored/displayed correctly | | Output → Persistence | Results saved to store/database | | Cross-component | Data shared correctly between components | | Stale data | No stale renders after state changes |

### Data Flow: PASS / FAIL
- Flow verified: [input → output]
- Stale data issues: [describe]
- Data loss points: [list]

Pass 6: User Journey Completeness

Walk through the complete user journey for the feature under evaluation. Example structure:

1. User provides input (form, selection, etc.)
2. System processes input
3. User reviews output
4. User can lock/finalize results
5. System handles dependencies between outputs
6. User views all deliverables
7. User can export/download results
8. User can re-process any unlocked item
9. Locked items show "outdated" if dependencies change

Adapt the journey steps above to match your project's actual user flow.

### User Journey: PASS / FAIL
- Steps completed: [X]/[total]
- Broken at step: [which]
- User experience: [smooth / friction at: describe]
