Golden Dataset Validation

Ensure data integrity, prevent duplicates, and maintain quality standards

Overview

This skill provides comprehensive validation patterns for the golden dataset, ensuring every entry meets quality standards before inclusion.

When to use this skill:

•Validating new documents before adding
•Running integrity checks on existing dataset
•Detecting duplicate or similar content
•Analyzing coverage gaps
•Pre-commit validation hooks

Schema Validation

Document Schema (v2.0)

json

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "required": ["id", "title", "source_url", "content_type", "sections"],
  "properties": {
    "id": {
      "type": "string",
      "pattern": "^[a-z0-9-]+$",
      "description": "Unique kebab-case identifier"
    },
    "title": {
      "type": "string",
      "minLength": 10,
      "maxLength": 200
    },
    "source_url": {
      "type": "string",
      "format": "uri",
      "description": "Canonical source URL (NOT placeholder)"
    },
    "content_type": {
      "type": "string",
      "enum": ["article", "tutorial", "research_paper", "documentation", "video_transcript", "code_repository"]
    },
    "bucket": {
      "type": "string",
      "enum": ["short", "long"]
    },
    "tags": {
      "type": "array",
      "items": {"type": "string"},
      "minItems": 2,
      "maxItems": 10
    },
    "sections": {
      "type": "array",
      "minItems": 1,
      "items": {
        "type": "object",
        "required": ["id", "title", "content"],
        "properties": {
          "id": {"type": "string", "pattern": "^[a-z0-9-/]+$"},
          "title": {"type": "string"},
          "content": {"type": "string", "minLength": 50},
          "granularity": {"enum": ["coarse", "fine", "summary"]}
        }
      }
    }
  }
}

Query Schema

json

{
  "type": "object",
  "required": ["id", "query", "difficulty", "expected_chunks", "min_score"],
  "properties": {
    "id": {"type": "string", "pattern": "^q-[a-z0-9-]+$"},
    "query": {"type": "string", "minLength": 5, "maxLength": 500},
    "modes": {"type": "array", "items": {"enum": ["semantic", "keyword", "hybrid"]}},
    "category": {"enum": ["specific", "broad", "negative", "edge", "coarse-to-fine"]},
    "difficulty": {"enum": ["trivial", "easy", "medium", "hard", "adversarial"]},
    "expected_chunks": {"type": "array", "items": {"type": "string"}, "minItems": 1},
    "min_score": {"type": "number", "minimum": 0, "maximum": 1}
  }
}

Validation Rules Summary

Rule	Purpose	Severity
No Placeholder URLs	Ensure real canonical URLs	Error
Unique Identifiers	No duplicate doc/query/section IDs	Error
Referential Integrity	Query chunks reference valid sections	Error
Content Quality	Title/content length, tag count	Warning
Difficulty Distribution	Balanced query difficulty levels	Warning

Quick Reference

Duplicate Detection Thresholds

Similarity	Action
>= 0.90	Block - Content too similar
>= 0.85	Warn - High similarity detected
>= 0.80	Note - Similar content exists
< 0.80	Allow - Sufficiently unique

Coverage Requirements

Metric	Minimum
Tutorials	>= 15% of documents
Research papers	>= 5% of documents
Domain coverage	>= 5 docs per expected domain
Hard queries	>= 10% of queries
Adversarial queries	>= 5% of queries

Difficulty Distribution Requirements

Level	Minimum Count
trivial	3
easy	3
medium	5
hard	3
