fix: resolve SplitInBatches output confusion for AI assistants (#97)
## Problem AI assistants were consistently connecting SplitInBatches node outputs backwards because: - Output index 0 = "done" (runs after loop completes) - Output index 1 = "loop" (processes items inside loop) This counterintuitive ordering caused incorrect workflow connections. ## Solution Enhanced the n8n-mcp system to expose and clarify output information: ### Database & Schema - Added `outputs` and `output_names` columns to nodes table - Updated NodeRepository to store/retrieve output information ### Node Parsing - Enhanced NodeParser to extract outputs and outputNames from nodes - Properly handles versioned nodes like SplitInBatchesV3 ### MCP Server - Modified getNodeInfo to return detailed output descriptions - Added connection guidance for each output - Special handling for loop nodes (SplitInBatches, IF, Switch) ### Documentation - Enhanced DocsMapper to inject critical output guidance - Added warnings about counterintuitive output ordering - Provides correct connection patterns for loop nodes ### Workflow Validation - Added validateSplitInBatchesConnection method - Detects reversed connections and provides specific errors - Added checkForLoopBack with depth limit to prevent stack overflow - Smart heuristics to identify likely connection mistakes ## Testing - Created comprehensive test suite (81 tests) - Unit tests for all modified components - Edge case handling for malformed data - Performance testing with large workflows ## Impact AI assistants will now: - See explicit output indices and names (e.g., "Output 0: done") - Receive clear connection guidance - Get validation errors when connections are reversed - Have enhanced documentation explaining the correct pattern Fixes #97 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
