feat: Update skills for n8n-mcp unified tool API (v1.1.0)

Browse Source 
BREAKING: Updated all skills to reflect n8n-mcp tool consolidation:

## Tool API Changes
- get_node_essentials → get_node({detail: "standard"})
- get_node_info → get_node({detail: "full"})

- Fixed "5 skills" → "7 skills" inconsistency in README

## Files Updated
- n8n-mcp-tools-expert: Complete rewrite of SKILL.md, SEARCH_GUIDE.md,
  VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md
- n8n-node-configuration: Updated SKILL.md, DEPENDENCIES.md
- n8n-validation-expert: Updated SKILL.md, ERROR_CATALOG.md, FALSE_POSITIVES.md

## Implementation Timeline
- **Week 1**: n8n Expression Syntax (PoC - 4 files, ~350 lines)
- **Week 2**: n8n MCP Tools Expert + n8n Workflow Patterns
- **Week 3**: n8n Validation Expert + n8n Node Configuration
- **Week 4**: Testing, refinement, documentation
- **Week 5-6**: Distribution, plugin packaging
## Five Skills to Implement
## The 7 Skills
### 1. n8n Expression Syntax
**Priority**: Foundation (Week 1)
- Teaches correct n8n expression syntax ({{}} patterns)
- Covers common mistakes and fixes
- Files: SKILL.md, COMMON_MISTAKES.md, EXAMPLES.md
- Critical gotcha: Webhook data under `$json.body`
### 2. n8n MCP Tools Expert
**Priority**: Highest (fixes 20% failure rate)
### 2. n8n MCP Tools Expert (HIGHEST PRIORITY)
- Teaches how to use n8n-mcp MCP tools effectively
- Covers node discovery, validation, workflow management
- Files: SKILL.md, SEARCH_GUIDE.md, VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md
- Covers unified tools: `get_node`, `validate_node`, `search_nodes`
- Workflow management with `n8n_update_partial_workflow`
- New: `n8n_deploy_template`, `n8n_workflow_versions`, `activateWorkflow`
### 3. n8n Workflow Patterns
**Priority**: High (addresses 813 webhook searches)
- Teaches proven workflow architectural patterns
- 5 patterns from 31,917 real workflows
- Files: SKILL.md + 5 pattern files (webhook, http, database, ai, scheduled)
- 5 patterns: webhook, HTTP API, database, AI, scheduled
### 4. n8n Validation Expert
**Priority**: Medium
- Interprets validation errors and guides fixing
- Handles false positives and validation loops
- Files: SKILL.md, ERROR_CATALOG.md, FALSE_POSITIVES.md
- Auto-fix with `n8n_autofix_workflow`
### 5. n8n Node Configuration
**Priority**: Medium
- Operation-aware node configuration guidance
- Property dependencies and common patterns
- Files: SKILL.md, DEPENDENCIES.md, OPERATION_PATTERNS.md
## Data-Driven Design
### 6. n8n Code JavaScript
- Write JavaScript in n8n Code nodes
- Data access patterns, `$helpers`, DateTime
These skills are based on telemetry analysis of:
- 447,557 real MCP tool usage events
- 31,917 workflows created
- 19,113 validation errors
- 15,107 validation feedback loops
### 7. n8n Code Python
- Write Python in n8n Code nodes
- Limitations awareness (no external libraries)
## Skill Structure
## Key MCP Tools
Each skill follows this format:
The n8n-mcp server provides these unified tools:
```markdown
---
name: Skill Name
description: When to use this skill. Use when [trigger conditions].
---
### Node Discovery
- `search_nodes` - Find nodes by keyword
- `get_node` - Unified node info with detail levels (minimal, standard, full) and modes (info, docs, search_properties, versions)
# Skill Name
### Validation
- `validate_node` - Unified validation with modes (minimal, full) and profiles (runtime, ai-friendly, strict)
- `validate_workflow` - Complete workflow validation
## [Content organized in sections]
```
### Workflow Management
- `n8n_create_workflow` - Create new workflows
- `n8n_update_partial_workflow` - Incremental updates (17 operation types including `activateWorkflow`)
- `n8n_validate_workflow` - Validate by ID
- `n8n_autofix_workflow` - Auto-fix common issues
- `n8n_deploy_template` - Deploy template to n8n instance
- `n8n_workflow_versions` - Version history and rollback
- `n8n_test_workflow` - Test execution
- `n8n_executions` - Manage executions
## Development Approach
### Templates
- `search_templates` - Multiple modes (keyword, by_nodes, by_task, by_metadata)
- `get_template` - Get template details
**Evaluation-Driven Development**:
1. Create 3+ evaluations FIRST for each skill
2. Establish baseline (test without skill)
3. Write minimal SKILL.md (under 500 lines)
4. Test against evaluations
5. Iterate until 100% pass
6. Add reference files as needed
### Guides
- `tools_documentation` - Meta-documentation for all tools
- `ai_agents_guide` - AI agent workflow guidance
## Key Implementation Guidelines
### File Organization
- Keep SKILL.md files under 500 lines
- Split complex content into reference files
- Use markdown with clear sections
- Link between related files
### Skill Activation
Skills activate automatically when queries match their description triggers:
- "How do I write n8n expressions?" → n8n Expression Syntax
- "Find me a Slack node" → n8n MCP Tools Expert
- "Build a webhook workflow" → n8n Workflow Patterns
### Cross-Skill Integration
Skills are designed to work together:
- Use n8n Workflow Patterns to identify structure
- Use n8n MCP Tools Expert to find nodes
- Use n8n Node Configuration for setup
- Use n8n Expression Syntax for data mapping
- Use n8n Validation Expert to validate

### When Adding New Skills
1. Create skill directory under `skills/`
2. Follow the structure in `docs/SKILLS_IMPLEMENTATION_GUIDE.md`
3. Write SKILL.md with frontmatter
4. Add reference files as needed
5. Create 3+ evaluations in `evaluations/`
6. Test thoroughly before committing

### When Creating Evaluations
Place in `evaluations/[skill-name]/eval-NNN-description.json`
### Skill Activation
Skills activate automatically when queries match their description triggers:
- "How do I write n8n expressions?" → n8n Expression Syntax
- "Find me a Slack node" → n8n MCP Tools Expert
- "Build a webhook workflow" → n8n Workflow Patterns

"query": "User question or scenario",
"expected_behavior": [
"List of expected behaviors",
"What skill should do",
"What content it should reference"
]
}
```
### Git Workflow
- Work on feature branches
- Commit frequently with clear messages
- Test skills before pushing
- Keep main branch stable
### Cross-Skill Integration
Skills are designed to work together:
- Use n8n Workflow Patterns to identify structure
- Use n8n MCP Tools Expert to find nodes
- Use n8n Node Configuration for setup
- Use n8n Expression Syntax for data mapping
- Use n8n Code JavaScript/Python for custom logic
- Use n8n Validation Expert to validate
