Reference Curator - Complete Skill Set

This document contains all 6 skills for curating, processing, and exporting reference documentation.

---

1. Reference Discovery

Searches for authoritative sources, validates credibility, and produces curated URL lists for crawling.

Source Priority Hierarchy

Tier	Source Type	Examples
Tier 1	Official documentation	docs.anthropic.com, docs.claude.com, platform.openai.com/docs
Tier 1	Engineering blogs (official)	anthropic.com/news, openai.com/blog
Tier 1	Official GitHub repos	github.com/anthropics/, github.com/openai/
Tier 2	Research papers	arxiv.org, papers with citations
Tier 2	Verified community guides	Cookbook examples, official tutorials
Tier 3	Community content	Blog posts, tutorials, Stack Overflow

Discovery Workflow

Step 1: Define Search Scope

search_config = {
    "topic": "prompt engineering",
    "vendors": ["anthropic", "openai", "google"],
    "source_types": ["official_docs", "engineering_blog", "github_repo"],
    "freshness": "past_year",
    "max_results_per_query": 20
}

Step 2: Generate Search Queries

def generate_queries(topic, vendors):
    queries = []
    for vendor in vendors:
        queries.append(f"site:docs.{vendor}.com {topic}")
        queries.append(f"site:{vendor}.com/docs {topic}")
        queries.append(f"site:{vendor}.com/blog {topic}")
        queries.append(f"site:github.com/{vendor} {topic}")
    queries.append(f"site:arxiv.org {topic}")
    return queries

Step 3: Validate and Score Sources

def score_source(url, title):
    score = 0.0
    if any(d in url for d in ['docs.anthropic.com', 'docs.claude.com', 'docs.openai.com']):
        score += 0.40  # Tier 1 official docs
    elif any(d in url for d in ['anthropic.com', 'openai.com', 'google.dev']):
        score += 0.30  # Tier 1 official blog/news
    elif 'github.com' in url and any(v in url for v in ['anthropics', 'openai', 'google']):
        score += 0.30  # Tier 1 official repos
    elif 'arxiv.org' in url:
        score += 0.20  # Tier 2 research
    else:
        score += 0.10  # Tier 3 community
    return min(score, 1.0)

def assign_credibility_tier(score):
    if score >= 0.60:
        return 'tier1_official'
    elif score >= 0.40:
        return 'tier2_verified'
    else:
        return 'tier3_community'

Output Format

{
  "discovery_date": "2025-01-28T10:30:00",
  "topic": "prompt engineering",
  "total_urls": 15,
  "urls": [
    {
      "url": "https://docs.anthropic.com/en/docs/prompt-engineering",
      "title": "Prompt Engineering Guide",
      "credibility_tier": "tier1_official",
      "credibility_score": 0.85,
      "source_type": "official_docs",
      "vendor": "anthropic"
    }
  ]
}

2. Web Crawler Orchestrator

Manages crawling operations using Firecrawl MCP with rate limiting and format handling.

Crawl Configuration

firecrawl:
  rate_limit:
    requests_per_minute: 20
    concurrent_requests: 3
  default_options:
    timeout: 30000
    only_main_content: true

Crawl Workflow

Determine Crawl Strategy

def select_strategy(url):
    if url.endswith('.pdf'):
        return 'pdf_extract'
    elif 'github.com' in url and '/blob/' in url:
        return 'raw_content'
    elif any(d in url for d in ['docs.', 'documentation']):
        return 'scrape'
    else:
        return 'scrape'

Execute Firecrawl

# Single page scrape
firecrawl_scrape(
    url="https://docs.anthropic.com/en/docs/prompt-engineering",
    formats=["markdown"],
    only_main_content=True,
    timeout=30000
)

# Multi-page crawl
firecrawl_crawl(
    url="https://docs.anthropic.com/en/docs/",
    max_depth=2,
    limit=50,
    formats=["markdown"]
)

Rate Limiting

class RateLimiter:
    def __init__(self, requests_per_minute=20):
        self.rpm = requests_per_minute
        self.request_times = deque()

    def wait_if_needed(self):
        now = time.time()
        while self.request_times and now - self.request_times[0] > 60:
            self.request_times.popleft()
        if len(self.request_times) >= self.rpm:
            wait_time = 60 - (now - self.request_times[0])
            if wait_time > 0:
                time.sleep(wait_time)
        self.request_times.append(time.time())

Error Handling

Error	Action
Timeout	Retry once with 2x timeout
Rate limit (429)	Exponential backoff, max 3 retries
Not found (404)	Log and skip
Access denied (403)	Log, mark as failed

---

3. Content Repository

Manages MySQL storage for the reference library. Handles document storage, version control, deduplication, and retrieval.

Core Operations

Store New Document:

def store_document(cursor, source_id, title, url, doc_type, raw_content_path):
    sql = """
    INSERT INTO documents (source_id, title, url, doc_type, crawl_date, crawl_status, raw_content_path)
    VALUES (%s, %s, %s, %s, NOW(), 'completed', %s)
    ON DUPLICATE KEY UPDATE
        version = version + 1,
        crawl_date = NOW(),
        raw_content_path = VALUES(raw_content_path)
    """
    cursor.execute(sql, (source_id, title, url, doc_type, raw_content_path))
    return cursor.lastrowid

Check Duplicate:

def is_duplicate(cursor, url):
    cursor.execute("SELECT doc_id FROM documents WHERE url_hash = SHA2(%s, 256)", (url,))
    return cursor.fetchone() is not None

Table Quick Reference

Table	Purpose	Key Fields
sources	Authorized content sources	source_type, credibility_tier, vendor
documents	Crawled document metadata	url_hash (dedup), version, crawl_status
distilled_content	Processed summaries	review_status, compression_ratio
review_logs	QA decisions	quality_score, decision
topics	Taxonomy	topic_slug, parent_topic_id

Status Values

• crawl_status: pending → completed | failed | stale
• review_status: pending → in_review → approved | needs_refactor | rejected
• decision: approve | refactor | deep_research | reject

4. Content Distiller

Transforms raw crawled content into structured, high-quality reference materials.

Distillation Goals

1. Compress - Reduce token count while preserving essential information
2. Structure - Organize content for easy retrieval and reference
3. Extract - Pull out code snippets, key concepts, and actionable patterns
4. Annotate - Add metadata for searchability and categorization

Extract Key Components

Extract Code Snippets:

def extract_code_snippets(content):
    pattern = r'```(\w*)\n([\s\S]*?)```'
    snippets = []
    for match in re.finditer(pattern, content):
        snippets.append({
            "language": match.group(1) or "text",
            "code": match.group(2).strip(),
            "context": get_surrounding_text(content, match.start(), 200)
        })
    return snippets

Extract Key Concepts:

def extract_key_concepts(content, title):
    prompt = f"""
    Analyze this document and extract key concepts:

    Title: {title}
    Content: {content[:8000]}

    Return JSON with:
    - concepts: [{{"term": "...", "definition": "...", "importance": "high|medium|low"}}]
    - techniques: [{{"name": "...", "description": "...", "use_case": "..."}}]
    - best_practices: ["..."]
    """
    return claude_extract(prompt)

Summary Template

# {title}

**Source:** {url}
**Type:** {source_type} | **Tier:** {credibility_tier}

## Executive Summary
{2-3 sentence overview}

## Key Concepts
{bulleted list of core concepts}

## Techniques & Patterns
{extracted techniques with use cases}

## Code Examples
{relevant code snippets}

## Best Practices

5. Quality Reviewer

Evaluates distilled content, routes decisions, and triggers refactoring or additional research.

Review Workflow

[Distilled Content]
       │
       ▼
┌─────────────────┐
│ Score Criteria  │ → accuracy, completeness, clarity, PE quality, usability
└─────────────────┘
       │
       ├── ≥ 0.85 → APPROVE → markdown-exporter
       ├── 0.60-0.84 → REFACTOR → content-distiller (with instructions)
       ├── 0.40-0.59 → DEEP_RESEARCH → web-crawler (with queries)
       └── < 0.40 → REJECT → archive with reason

Scoring Criteria

Criterion	Weight	Checks
Accuracy	0.25	Factual correctness, up-to-date info, proper attribution
Completeness	0.20	Covers key concepts, includes examples, addresses edge cases
Clarity	0.20	Clear structure, concise language, logical flow
PE Quality	0.25	Demonstrates techniques, before/after examples, explains why
Usability	0.10	Easy to reference, searchable keywords, appropriate length

Calculate Final Score

WEIGHTS = {
    "accuracy": 0.25,
    "completeness": 0.20,
    "clarity": 0.20,
    "prompt_engineering_quality": 0.25,
    "usability": 0.10
}

def calculate_quality_score(assessment):
    return sum(
        assessment[criterion]["score"] * weight
        for criterion, weight in WEIGHTS.items()
    )

Route Decision

def determine_decision(score, assessment):
    if score >= 0.85:
        return "approve", None, None
    elif score >= 0.60:
        instructions = generate_refactor_instructions(assessment)
        return "refactor", instructions, None
    elif score >= 0.40:
        queries = generate_research_queries(assessment)
        return "deep_research", None, queries
    else:
        return "reject", f"Quality score {score:.2f} below minimum", None

Prompt Engineering Quality Checklist

• Demonstrates specific techniques (CoT, few-shot, etc.)
• Shows before/after examples
• Explains why techniques work, not just what
• Provides actionable patterns
• Includes edge cases and failure modes
• References authoritative sources

        content.append("---")
        content.append("")
    content.append(doc['structured_content'])
    return "\n".join(content)

Fine-tuning Export (JSONL)

def export_fine_tuning_dataset(content_list, config):
    with open('fine_tuning.jsonl', 'w') as f:
        for doc in content_list:
            sample = {
                "messages": [
                    {"role": "system", "content": "You are an expert on AI and prompt engineering."},
                    {"role": "user", "content": f"Explain {doc['title']}"},

                    "quality_score": doc['quality_score']
                }
            }
            f.write(json.dumps(sample) + '\n')

Cross-Reference Generation

def add_cross_references(doc, all_docs):
    related = []
    doc_concepts = set(c['term'].lower() for c in doc['key_concepts'])

    for other in all_docs:
        if other['doc_id'] == doc['doc_id']:
            continue
        other_concepts = set(c['term'].lower() for c in other['key_concepts'])
        overlap = len(doc_concepts & other_concepts)
        if overlap >= 2:
            related.append({
                "title": other['title'],
                "path": generate_relative_path(doc, other),
                "overlap": overlap
            })

    return sorted(related, key=lambda x: x['overlap'], reverse=True)[:5]
