- Reduced average description length from 250-450 to 93-129 chars
- Documentation tools now average 129 chars per description
- Management tools average just 93 chars per description
- Moved detailed documentation to tools_documentation() system
- Only 2 tools exceed 200 chars (necessarily verbose)
Also includes search_nodes improvements:
- Fixed primary node ranking (webhook, HTTP Request now appear first)
- Fixed FUZZY mode threshold for better typo tolerance
- Removed unnecessary searchInfo messages
- Fixed HTTP node type case sensitivity issue
This significantly improves AI agent performance by reducing context usage
while preserving all essential information.

Critical fixes based on Claude Desktop feedback:
1. Fixed crypto documentation: require('crypto') IS available despite editor warnings
- Added clear examples of crypto usage
- Updated validation to guide correct require() usage
2. Clarified $helpers vs standalone functions
- $getWorkflowStaticData() is standalone, NOT $helpers.getWorkflowStaticData()
- Added validation to catch incorrect usage (prevents '$helpers is not defined' errors)
- Enhanced examples showing proper $helpers availability checks
3. Fixed JMESPath numeric literal documentation
- n8n requires backticks around numbers in filters: [?age >= `18`]
- Added multiple examples and validation to detect missing backticks
- Prevents 'JMESPath syntax error' that Claude Desktop encountered
4. Fixed webhook data access gotcha
- Webhook payload is at items[0].json.body, NOT items[0].json
- Added dedicated 'Webhook Data Access' section with clear examples
- Created process_webhook_data task template
- Added validation to detect incorrect webhook data access patterns
All fixes based on production workflows TaNqYoZNNeHC4Hne and JZ9urD7PNClDZ1bm

Root cause: AI agents were placing error handling properties inside `parameters` instead of at node level
Major changes:
- Enhanced workflow validator to check for ALL node-level properties (expanded from 6 to 11)
- Added validation for onError property values and deprecation warnings for continueOnFail
- Updated all examples to use modern error handling (onError instead of continueOnFail)
- Added comprehensive node-level properties documentation in tools_documentation
- Enhanced MCP tool documentation for n8n_create_workflow and n8n_update_partial_workflow
- Added test script demonstrating correct node-level property usage
Node-level properties now validated:
- credentials, disabled, notes, notesInFlow, executeOnce
- onError, retryOnFail, maxTries, waitBetweenTries, alwaysOutputData
- continueOnFail (deprecated)
Validation improvements:
- Detects misplaced properties and provides clear fix examples
- Shows complete node structure when properties are incorrectly placed
- Type validation for all node-level boolean and string properties
- Smart error messages with correct placement guidance
