czlonkowski bf9e1b46a3 docs: Document workflow activation limitation across skills
Add critical limitation notice that workflow activation is not supported
via API or MCP and requires manual activation in n8n UI.

Changes:
- WORKFLOW_GUIDE.md: Added prominent warning in lifecycle section with
  deployment steps for users
- SKILL.md (workflow-patterns): Added inline warning in deployment checklist
- scheduled_tasks.md: Added activation reminder in deployment checklist
- VALIDATION_GUIDE.md: Added to best practices "Do" section

Context: During practical workflow deployment, discovered that the
n8n_update_partial_workflow operation with active:true setting does not
activate workflows. This is a critical limitation that users must understand
to successfully deploy workflows built via MCP.

Locations updated (4 files):
1. skills/n8n-mcp-tools-expert/WORKFLOW_GUIDE.md (primary)
2. skills/n8n-workflow-patterns/SKILL.md (deployment phase)
3. skills/n8n-workflow-patterns/scheduled_tasks.md (deployment checklist)
4. skills/n8n-mcp-tools-expert/VALIDATION_GUIDE.md (best practices)

n8n MCP Tools Expert

Expert guide for using n8n-mcp MCP tools effectively.


Purpose

Teaches how to use n8n-mcp MCP server tools correctly for efficient workflow building.

Activates On

  • search nodes
  • find node
  • validate
  • MCP tools
  • template
  • workflow
  • n8n-mcp
  • tool selection

File Count

5 files, ~1,150 lines total

Priority

HIGHEST - Fixes 20% MCP tool failure rate

Dependencies

n8n-mcp tools: All of them! (40+ tools)

Related skills:

  • n8n Expression Syntax (write expressions for workflows)
  • n8n Workflow Patterns (use tools to build patterns)
  • n8n Validation Expert (interpret validation results)
  • n8n Node Configuration (configure nodes found with tools)

Coverage

Core Topics

  • Tool selection guide (which tool for which task)
  • nodeType format differences (nodes-base.* vs n8n-nodes-base.*)
  • Validation profiles (minimal/runtime/ai-friendly/strict)
  • Smart parameters (branch, case for multi-output nodes)
  • Auto-sanitization system
  • Workflow management (15 operation types)
  • AI connection types (8 types)

Tool Categories

  • Node Discovery (search, list, essentials, info)
  • Configuration Validation (minimal, operation, workflow)
  • Workflow Management (create, update, validate)
  • Template Library (search, get)
  • Documentation (tools, database stats)

Evaluations

5 scenarios (100% coverage expected):

  1. eval-001: Tool selection (search_nodes)
  2. eval-002: nodeType format (nodes-base.* prefix)
  3. eval-003: Validation workflow (profiles)
  4. eval-004: essentials vs info (5KB vs 100KB)
  5. eval-005: Smart parameters (branch, case)

Key Features

Data-Driven: Based on 447,557 real MCP tool events Telemetry Insights: Actual usage patterns (56s between edits, 18s between search/essentials) Critical Mistakes: Highlights 20% failure rate issues Smart Parameters: Teaches semantic branch/case routing Auto-Sanitization: Explains automatic fixes Comprehensive: Covers all 40+ tools

Files

  • SKILL.md (480 lines) - Core tool usage guide
  • SEARCH_GUIDE.md (220 lines) - Node discovery tools
  • VALIDATION_GUIDE.md (250 lines) - Validation tools and profiles
  • WORKFLOW_GUIDE.md (200 lines) - Workflow management
  • README.md (this file) - Skill metadata

Success Metrics

Expected outcomes:

  • Correct nodeType formats (nodes-base.* for search)
  • get_node_essentials preferred over get_node_info
  • Validation profiles used correctly
  • Smart parameters for IF/Switch nodes
  • 20% failure rate reduced to <5%

Critical Insights

From MCP Testing Log:

  • search → essentials: 9,835 occurrences, 18s avg
  • validate → fix: 7,841 loops, 23s thinking, 58s fixing
  • update_partial: 38,287 uses, 56s between edits
  • get_node_info: 20% failure rate (use essentials!)
