Problem

Current Behavior

1. User creates a workflow using main workflow AI edit
2. AI generates a SubAgentFlow node (reference)
3. ❌ The corresponding SubAgentFlow definition (internal nodes/connections) is not created
4. ❌ SubAgentFlow dialog cannot be opened ("Not linked" warning)

Expected Behavior

1. User creates a workflow using main workflow AI edit
2. AI generates a SubAgentFlow node (reference)
3. ✅ The corresponding SubAgentFlow definition with internal structure is also created
4. ✅ SubAgentFlow dialog opens normally

Solution

Implemented a hybrid approach to ensure SubAgentFlow definitions are always created:

1. Primary: Extended workflow-schema.json with AI generation guidance to instruct AI to generate complete SubAgentFlow definitions
2. Fallback: Added resolveSubAgentFlows post-processing to create minimal structures (Start → End) for any missing definitions

Changes

resources/workflow-schema.json

• Added aiGenerationGuidance section to subAgentFlow node type
• Added workflowStructure section documenting the subAgentFlows array field

src/extension/commands/ai-generation.ts

• Added SubAgentFlow requirements to AI prompt
• Added createMinimalSubAgentFlow() function
• Added resolveSubAgentFlows() function for fallback processing

src/extension/utils/validate-workflow.ts

• Added validateSubAgentFlowReferences() function for reference integrity checks

src/extension/services/refinement-service.ts

• Added same resolveSubAgentFlows processing for AI refinement flow

src/webview/src/stores/workflow-store.ts

• Updated addGeneratedWorkflow and updateWorkflow to handle subAgentFlows

Impact

• SubAgentFlow nodes created via AI edit now have proper internal definitions
• SubAgentFlow dialog opens correctly after AI generation
• No breaking changes to existing workflows

Testing

• Manual E2E testing completed
• AI generates complete SubAgentFlow internal structure (not just Start→End)
• SubAgentFlow dialog opens correctly
• Code quality checks passed (format, lint, build)
