Flow Analyze Workflow Structure

Key Files to Analyze

Analysis Process

Step 1: List All Files

ls -la src/workflows/my_workflow/

Step 2: Identify Workflow Entry Point

# Find the workflow class
grep -n "class.*Workflow" src/workflows/my_workflow/workflow.ts
grep -n "execute(" src/workflows/my_workflow/workflow.ts

Step 3: Extract Input/Output Types

# Find interface definitions
grep -n "interface.*Input" src/workflows/my_workflow/*.ts
grep -n "interface.*Output" src/workflows/my_workflow/*.ts

# Find Zod schemas
grep -n "z.object" src/workflows/my_workflow/types.ts

Step 4: List All Activities

# Find exported functions in activities.ts
grep -n "export.*async function" src/workflows/my_workflow/activities.ts
grep -n "export function" src/workflows/my_workflow/activities.ts

Step 5: Map Activity Parameters

For each activity, note:

• Function name
• Parameters (types and count)
• Return type
• Dependencies (other activities, services)

# View activity signatures
grep -A5 "export.*function" src/workflows/my_workflow/activities.ts

Step 6: Identify LLM Calls

# Find completion calls
grep -n "completion(" src/workflows/my_workflow/activities.ts
grep -n "await.*completion" src/workflows/my_workflow/activities.ts

# Find prompt usage
grep -n "Prompt" src/workflows/my_workflow/activities.ts

Step 7: Map Control Flow

Read workflow.ts to understand:

• Sequential vs parallel execution
• Conditional logic
• Loop structures
• Error handling patterns

Step 8: Identify External Dependencies

# Find external imports
grep -n "^import" src/workflows/my_workflow/*.ts | grep -v "\./"

# Find API calls
grep -n "fetch(" src/workflows/my_workflow/*.ts
grep -n "axios" src/workflows/my_workflow/*.ts

Step 9: Check readme.xml for Context

cat src/workflows/my_workflow/readme.xml

Analysis Output Template

Create a migration analysis document:

# Workflow Migration Analysis: [workflow_name]

## Overview
- **Location**: src/workflows/my_workflow/
- **Purpose**: [from readme.xml]
- **Complexity**: [low/medium/high]

## Files to Migrate

| File | Status | Notes |
|------|--------|-------|
| workflow.ts | Needs conversion | Class → function |
| activities.ts | Needs conversion | 5 activities → steps |
| types.ts | Partial | Add Zod schemas |
| prompts.ts | Needs conversion | 3 prompts |

## Workflow Input/Output

### Input
```typescript
interface WorkflowInput {
  userId: string;
  options: ProcessOptions;
}

Output

interface WorkflowOutput {
  success: boolean;
  resultId: string;
}

Activities (→ Steps)

Prompts

Control Flow

1. Fetch user data (sequential)
2. Analyze data (with conditional)
3. Save results (sequential)

Dependencies

• External API: https://api.example.com
• Service: EmailService
• Helper: formatData()

Migration Risks

• Complex conditional logic in workflow
• Custom error handling to review
• External service authentication

Estimated Effort

• Steps: 5 activities to convert
• Prompts: 2 prompts to create
• Types: Add 3 Zod schemas

## Quick Analysis Commands

### Get workflow overview

```bash
# Count activities
grep -c "export.*function" src/workflows/my_workflow/activities.ts

# Count prompts
grep -c "role:" src/workflows/my_workflow/prompts.ts

# Check for Handlebars syntax
grep -c "{{#if" src/workflows/my_workflow/prompts.ts

# Check for zod imports (need conversion)
grep "from 'zod'" src/workflows/my_workflow/*.ts

Generate activity list

grep "export.*function" src/workflows/my_workflow/activities.ts | \
  sed 's/export async function /- /' | \
  sed 's/export function /- /' | \
  sed 's/(.*//'

Output SDK Target Structure

After migration, the folder should look like:

src/workflows/my_workflow/
├── workflow.ts           # Converted workflow() function
├── steps.ts              # Converted step() definitions
├── types.ts              # Types with Zod schemas
├── [email protected]     # Converted prompts
├── [email protected]
└── scenarios/            # NEW: Test scenarios
    └── basic_input.json
