e19ea6ea8d docs: Remove telemetry and research context from user-facing documentation
Clean up all README files to focus on user value rather than research metrics.
Remove telemetry numbers and research context that isn't useful for end users.

## Changes

**Main README.md**:
- Removed "Based on 447,557 real MCP tool usage events" section
- Replaced failure rate metrics with user benefits
- Removed entire "Data-Driven Design" section with telemetry statistics
- Fixed all GitHub links to use czlonkowski/n8n-mcp
- Updated "Repository Stats" to "What's Included" with user-focused content

**dist/README.md**:
- Changed "HIGHEST PRIORITY" to "recommended to install first"
- Added link to n8n-mcp repository
- More user-friendly language throughout

**Skill README.md files**:
- n8n-mcp-tools-expert: Removed "447,557 events", "20% failure rate" metrics
- n8n-workflow-patterns: Removed "Based on 31,917 real workflows"
- n8n-validation-expert: Removed "From 7,841 validate → fix cycles"
- Replaced frequency percentages with priority levels (Highest/High/Medium/Low)
- Reframed "Success Metrics" as "What You'll Learn"
- Changed "Critical Insights from telemetry" to "Key Insights" for users

## Kept What Matters

- Template counts (2,653+) - this is a feature, not research
- Node counts (525+) - this is a feature
- Practical insights (validation takes 2-3 iterations, false positives exist)
- Best practices and common patterns

## Result

Documentation now focuses on what users need to know to use the skills
effectively, rather than the research that informed their creation.

All distribution packages regenerated with cleaned documentation.

94c7036d29 fix: Use lowercase-with-hyphens skill names for Claude.ai compatibility
Fix skill names in SKILL.md frontmatter to comply with Claude.ai requirements:
"Skill name in SKILL.md can only contain lowercase letters, numbers, and hyphens."

## Changes

Updated skill names from "Title Case With Spaces" to "lowercase-with-hyphens":

1. "n8n Expression Syntax" → "n8n-expression-syntax"
2. "n8n MCP Tools Expert" → "n8n-mcp-tools-expert"
3. "n8n Workflow Patterns" → "n8n-workflow-patterns"
4. "n8n Validation Expert" → "n8n-validation-expert"
5. "n8n Node Configuration" → "n8n-node-configuration"

## Files Modified

- skills/n8n-expression-syntax/SKILL.md
- skills/n8n-mcp-tools-expert/SKILL.md
- skills/n8n-workflow-patterns/SKILL.md
- skills/n8n-validation-expert/SKILL.md
- skills/n8n-node-configuration/SKILL.md

## Distribution Packages

Regenerated all distribution zip files with corrected SKILL.md:
- dist/n8n-expression-syntax-v1.0.0.zip
- dist/n8n-mcp-tools-expert-v1.0.0.zip
- dist/n8n-workflow-patterns-v1.0.0.zip
- dist/n8n-validation-expert-v1.0.0.zip
- dist/n8n-node-configuration-v1.0.0.zip
- dist/n8n-mcp-skills-claude-code-v1.0.0.zip

Skills can now be uploaded to Claude.ai without naming errors.

33e83c29dc refactor: Remove research context from skill content
Cleaned up all skills to remove research/telemetry context that was used
during design but is not needed at runtime when AI agents use the skills.

## Changes Made

### Pattern 1: Research Framing Removed
- "From analysis of X workflows/events" → Removed
- "From telemetry analysis:" → Replaced with operational context
- "Based on X real workflows" → Simplified to general statements

### Pattern 2: Popularity Metrics Removed
- "**Popularity**: Second most common (892 templates)" → Removed entirely
- "813 searches", "456 templates", etc. → Removed

### Pattern 3: Frequency Percentages Converted
- "**Frequency**: 45% of errors" → "Most common error"
- "**Frequency**: 28%" → "Second most common"
- "**Frequency**: 12%" → "Common error"
- Percentages in tables → Priority levels (Highest/High/Medium/Low)

### Pattern 4: Operational Guidance Kept
-  Success rates (91.7%) - helps tool selection
-  Average times (18s, 56s) - sets expectations
-  Relative priority (most common, typical) - guides decisions
-  Iteration counts (2-3 cycles) - manages expectations

## Files Modified (19 files across 4 skills)

**Skill #2: MCP Tools Expert (5 files)**
- Removed telemetry occurrence counts
- Kept success rates and average times

**Skill #3: Workflow Patterns (7 files)**
- Removed all popularity metrics from pattern files
- Removed "From analysis of 31,917 workflows"
- Removed template counts

**Skill #4: Validation Expert (4 files)**
- Converted frequency % to priority levels
- Removed "From analysis of 19,113 errors"
- Removed telemetry loop counts (kept iteration guidance)

**Skill #5: Node Configuration (3 files)**
- Removed workflow update counts
- Removed essentials call counts
- Kept success rates and timing guidance

## Result

Skills now provide clean, focused runtime guidance without research
justification. Content is more actionable for AI agents using the skills.

All technical guidance, examples, patterns, and operational metrics preserved.
Only removed: research methodology, data source attribution, and statistical
justification for design decisions.

68770a2e14 feat: Complete Skill #4 - n8n Validation Expert
Implements comprehensive validation error interpretation and systematic fixing guidance.
Addresses the validation feedback loop problem (15,107 loops from 19,113 errors).

Files created:
- 4 evaluations testing error interpretation, false positives, auto-sanitization, validation loop
- SKILL.md (690 lines) - Validation philosophy, loop pattern, profiles, auto-sanitization
- ERROR_CATALOG.md (865 lines) - 9 error types with examples and fixes
- FALSE_POSITIVES.md (669 lines) - 6 false positive patterns with decision framework
- README.md (329 lines) - Skill metadata with telemetry statistics

Key features:
- Error severity levels (errors/warnings/suggestions)
- Validation loop pattern (2-3 iterations, 23s+58s average)
- 4 validation profiles (minimal/runtime/ai-friendly/strict)
- Auto-sanitization system (operator structure fixes)
- False positive recognition (~40% of warnings acceptable)
- Error distribution analysis (missing_required 45%, invalid_value 28%)
- Recovery strategies (progressive validation, error triage, clean connections)
- Decision framework for warning acceptance

Error catalog:
- missing_required (45%) - Required field not provided
- invalid_value (28%) - Value doesn't match allowed options
- type_mismatch (12%) - Wrong data type
- invalid_expression (8%) - Expression syntax errors
- invalid_reference (5%) - Referenced node doesn't exist
- operator_structure (2%) - Auto-fixed automatically

False positive patterns:
- Missing error handling (acceptable for dev/test)
- No retry logic (acceptable for internal APIs)
- Missing rate limiting (acceptable for low volume)
- Unbounded queries (acceptable for small datasets)
- Missing input validation (acceptable for trusted sources)
- Hardcoded credentials (never acceptable!)

Validation insights:
- 79% of validation errors lead to feedback loops
- Average 2-3 iterations to valid configuration
- 94% success rate within 3 iterations
- ai-friendly profile reduces false positives by 60%
- Auto-sanitization handles operator structure issues automatically

Total: ~2,553 lines across 8 files

Based on analysis of 19,113 validation errors and 15,107 feedback loops.
