# Using Skill Seekers with Cursor IDE
**Last Updated:** February 5, 2026
**Status:** Production Ready
**Difficulty:** Easy ⭐
---
## 🎯 The Problem
Cursor IDE offers powerful AI coding assistance, but:
- **Generic Knowledge** - AI doesn't know your project-specific frameworks
- **No Custom Context** - Can't reference your internal docs or codebase patterns
- **Manual Context** - Copy-pasting documentation is tedious and error-prone
- **Inconsistent** - AI responses vary based on what context you provide
**Example:**
> "When building a Django app in Cursor, the AI might suggest outdated patterns or miss project-specific conventions. You want the AI to 'know' your framework documentation without manual prompting."
---
## ✨ The Solution
Use Skill Seekers to create **custom documentation** for Cursor's AI:
1. **Generate structured docs** from any framework or codebase
2. **Package as .cursorrules** - Cursor's custom instruction format
3. **Automatic Context** - AI references your docs in every interaction
4. **Project-Specific** - Different rules per project
**Result:**
Cursor's AI becomes an expert in your frameworks with persistent, automatic context.
---
## 🚀 Quick Start (5 Minutes)
### Prerequisites
- Cursor IDE installed (https://cursor.sh/)
- Python 3.10+ (for Skill Seekers)
### Installation
```bash
# Install Skill Seekers
pip install skill-seekers
# Verify installation
skill-seekers --version
```
### Generate .cursorrules
```bash
# Example: Django framework
skill-seekers scrape --config configs/django.json
# Package for Cursor
skill-seekers package output/django --target markdown
# Extract SKILL.md (this becomes your .cursorrules content)
# output/django-markdown/SKILL.md
```
### Setup in Cursor
**Option 1: Global Rules** (applies to all projects)
```bash
# Copy to Cursor's global config
cp output/django-markdown/SKILL.md ~/.cursor/.cursorrules
```
**Option 2: Project-Specific Rules** (recommended)
```bash
# Copy to your project root
cp output/django-markdown/SKILL.md /path/to/your/project/.cursorrules
```
**Option 3: Multiple Frameworks**
```bash
# Create modular rules file
cat > /path/to/your/project/.cursorrules << 'EOF'
# Django Framework Expert
You are an expert in Django. Use the following documentation:
EOF
# Append Django docs
cat output/django-markdown/SKILL.md >> /path/to/your/project/.cursorrules
# Add React if needed
echo "\n\n# React Framework Expert\n" >> /path/to/your/project/.cursorrules
cat output/react-markdown/SKILL.md >> /path/to/your/project/.cursorrules
```
### Test in Cursor
1. Open your project in Cursor
2. Open any file (`.py`, `.js`, etc.)
3. Use Cursor's AI chat (Cmd+K or Cmd+L)
4. Ask: "How do I create a Django model with relationships?"
**Expected:** AI responds using patterns and examples from your .cursorrules!
---
## 📖 Detailed Setup Guide
### Step 1: Choose Your Documentation Source
**Option A: Framework Documentation**
```bash
# Available presets: django, fastapi, react, vue, etc.
skill-seekers scrape --config configs/react.json
skill-seekers package output/react --target markdown
```
**Option B: GitHub Repository**
```bash
# Scrape from GitHub repo
skill-seekers github --repo facebook/react --name react
skill-seekers package output/react --target markdown
```
**Option C: Local Codebase**
```bash
# Analyze your own codebase
skill-seekers analyze --directory /path/to/repo --comprehensive
skill-seekers package output/codebase --target markdown
```
**Option D: Multiple Sources**
```bash
# Combine docs + code
skill-seekers unified \
--docs-config configs/fastapi.json \
--github fastapi/fastapi \
--name fastapi-complete
skill-seekers package output/fastapi-complete --target markdown
```
### Step 2: Optimize for Cursor
Cursor has a **200KB limit** for .cursorrules. Skill Seekers markdown output is optimized, but for very large documentation:
**Strategy 1: Summarize (Recommended)**
```bash
# Use AI enhancement to create concise version
skill-seekers enhance output/django --mode LOCAL
# Result: More concise, better structured SKILL.md
```
**Strategy 2: Split by Category**
```bash
# Create separate rules files per category
# In your .cursorrules:
cat > .cursorrules << 'EOF'
# Django Models Expert
You are an expert in Django models and ORM.
When working with Django models, reference these patterns:
EOF
# Extract only models category from references/
cat output/django/references/models.md >> .cursorrules
```
**Strategy 3: Router Approach**
```bash
# Use router skill (generates high-level overview)
skill-seekers unified \
--docs-config configs/django.json \
--build-router
# Result: Lightweight architectural guide
cat output/django/ARCHITECTURE.md > .cursorrules
```
### Step 3: Configure Cursor Settings
**.cursorrules format:**
```markdown
# Framework Expert Instructions
You are an expert in [Framework Name]. Follow these guidelines:
## Core Concepts
[Your documentation here]
## Common Patterns
[Patterns from Skill Seekers]
## Code Examples
[Examples from documentation]
## Best Practices
- Pattern 1
- Pattern 2
## Anti-Patterns to Avoid
- Anti-pattern 1
- Anti-pattern 2
```
**Cursor respects this structure** and uses it as persistent context.
### Step 4: Test and Refine
**Good prompts to test:**
```
1. "Create a [Framework] component that does X"
2. "What's the recommended pattern for Y in [Framework]?"
3. "Refactor this code to follow [Framework] best practices"
4. "Explain how [Specific Feature] works in [Framework]"
```
**Signs it's working:**
- AI mentions specific framework concepts
- Suggests code matching documentation patterns
- References framework-specific terminology
- Provides accurate, up-to-date examples
---
## 🎨 Advanced Usage
### Multi-Framework Projects
```bash
# Generate rules for full-stack project
skill-seekers scrape --config configs/fastapi.json
skill-seekers scrape --config configs/react.json
skill-seekers scrape --config configs/postgresql.json
skill-seekers package output/fastapi --target markdown
skill-seekers package output/react --target markdown
skill-seekers package output/postgresql --target markdown
# Combine into single .cursorrules
cat > .cursorrules << 'EOF'
# Full-Stack Expert (FastAPI + React + PostgreSQL)
You are an expert in full-stack development using FastAPI, React, and PostgreSQL.
---
# Backend: FastAPI
EOF
cat output/fastapi-markdown/SKILL.md >> .cursorrules
echo "\n\n---\n# Frontend: React\n" >> .cursorrules
cat output/react-markdown/SKILL.md >> .cursorrules
echo "\n\n---\n# Database: PostgreSQL\n" >> .cursorrules
cat output/postgresql-markdown/SKILL.md >> .cursorrules
```
### Project-Specific Patterns
```bash
# Analyze your codebase
skill-seekers analyze --directory . --comprehensive
# Extract patterns and architecture
cat output/codebase/SKILL.md > .cursorrules
# Add custom instructions
cat >> .cursorrules << 'EOF'
## Project-Specific Guidelines
### Architecture
- Use EventBus pattern for cross-component communication
- All API calls go through services/api.ts
- State management with Zustand (not Redux)
### Naming Conventions
- Components: PascalCase (e.g., UserProfile.tsx)
- Hooks: camelCase with 'use' prefix (e.g., useAuth.ts)
- Utils: camelCase (e.g., formatDate.ts)
### Testing
- Unit tests: *.test.ts
- Integration tests: *.integration.test.ts
- Use vitest, not jest
EOF
```
### Dynamic Context per File Type
Cursor supports **directory-specific rules**:
```bash
# Backend rules (for Python files)
cat output/fastapi-markdown/SKILL.md > backend/.cursorrules
# Frontend rules (for TypeScript files)
cat output/react-markdown/SKILL.md > frontend/.cursorrules
# Database rules (for SQL files)
cat output/postgresql-markdown/SKILL.md > database/.cursorrules
```
When you open a file, Cursor uses the closest `.cursorrules` in the directory tree.
### Cursor + RAG Pipeline
For **massive documentation** (>200KB):
1. **Use Pinecone/Chroma for vector storage**
2. **Use Cursor for code generation**
3. **Build API to query vectors**
```python
# cursor_rag.py - Custom Cursor context provider
from pinecone import Pinecone
from openai import OpenAI
def get_relevant_docs(query: str, top_k: int = 3) -> str:
"""Fetch relevant docs from vector store."""
pc = Pinecone()
index = pc.Index("framework-docs")
# Create query embedding
openai_client = OpenAI()
response = openai_client.embeddings.create(
model="text-embedding-ada-002",
input=query
)
query_embedding = response.data[0].embedding
# Query Pinecone
results = index.query(
vector=query_embedding,
top_k=top_k,
include_metadata=True
)
# Format for Cursor
context = "\n\n".join([
f"**{m['metadata']['category']}**: {m['metadata']['text']}"
for m in results["matches"]
])
return context
# Usage in .cursorrules
# "When answering questions, first call cursor_rag.py to get relevant context"
```
---
## 💡 Best Practices
### 1. Keep Rules Focused
**Good:**
```markdown
# Django ORM Expert
You are an expert in Django's ORM system.
Focus on:
- Model definitions
- QuerySets and managers
- Database relationships
- Migrations
[Detailed ORM documentation]
```
**Bad:**
```markdown
# Everything Expert
You know everything about Django, React, AWS, Docker, and 50 other technologies...
[Huge wall of text]
```
### 2. Use Hierarchical Structure
```markdown
# Framework Expert
## 1. Core Concepts (High-level)
Brief overview of key concepts
## 2. Common Patterns (Mid-level)
Practical patterns and examples
## 3. API Reference (Low-level)
Detailed API documentation
## 4. Troubleshooting
Common issues and solutions
```
### 3. Include Anti-Patterns
```markdown
## Anti-Patterns to Avoid
❌ **DON'T** use class-based components in React
✅ **DO** use functional components with hooks
❌ **DON'T** mutate state directly
✅ **DO** use setState or useState updater function
```
### 4. Add Code Examples
```markdown
## Creating a Django Model
✅ **Recommended Pattern:**
```python
from django.db import models
class Product(models.Model):
name = models.CharField(max_length=200)
price = models.DecimalField(max_digits=10, decimal_places=2)
created_at = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['-created_at']
def __str__(self):
return self.name
```
### 5. Update Regularly
```bash
# Set up monthly refresh
crontab -e
# Add line to regenerate rules monthly
0 0 1 * * cd ~/projects && skill-seekers scrape --config configs/django.json && skill-seekers package output/django --target markdown && cp output/django-markdown/SKILL.md ~/.cursorrules
```
---
## 🔥 Real-World Examples
### Example 1: Django + React Full-Stack
**.cursorrules:**
```markdown
# Full-Stack Developer Expert (Django + React)
## Backend: Django REST Framework
You are an expert in Django and Django REST Framework.
### Serializers
Always use ModelSerializer for database models:
```python
from rest_framework import serializers
from .models import User
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ['id', 'username', 'email', 'date_joined']
read_only_fields = ['id', 'date_joined']
```
### ViewSets
Use ViewSets for CRUD operations:
```python
from rest_framework import viewsets
class UserViewSet(viewsets.ModelViewSet):
queryset = User.objects.all()
serializer_class = UserSerializer
```
---
## Frontend: React + TypeScript
You are an expert in React with TypeScript.
### Components
Always type props and use functional components:
```typescript
interface UserProps {
user: User;
onUpdate: (user: User) => void;
}
export function UserProfile({ user, onUpdate }: UserProps) {
// Component logic
}
```
### API Calls
Use TanStack Query for data fetching:
```typescript
import { useQuery } from '@tanstack/react-query';
function useUser(id: string) {
return useQuery({
queryKey: ['user', id],
queryFn: () => api.getUser(id),
});
}
```
## Project Conventions
- Backend: `/api/v1/` prefix for all endpoints
- Frontend: `/src/features/` for feature-based organization
- Tests: Co-located with source files (`.test.ts`)
- API client: `src/lib/api.ts` (single source of truth)
```
### Example 2: Godot Game Engine
**.cursorrules:**
```markdown
# Godot 4.x Game Developer Expert
You are an expert in Godot 4.x game development with GDScript.
## Scene Structure
Always use scene tree hierarchy:
- Root node matches script class name
- Group related nodes under containers
- Use descriptive node names (PascalCase)
## Signals
Prefer signals over direct function calls:
```gdscript
# Declare signal
signal health_changed(new_health: int)
# Emit signal
health_changed.emit(current_health)
# Connect in parent
player.health_changed.connect(_on_player_health_changed)
```
## Node Access
Use @onready for node references:
```gdscript
@onready var sprite = $Sprite2D
@onready var animation_player = $AnimationPlayer
```
## Project Patterns (from codebase analysis)
### EventBus Pattern
Use autoload EventBus for global events:
```gdscript
# EventBus.gd (autoload)
signal game_started
signal game_over(score: int)
# In any script
EventBus.game_started.emit()
```
### Resource-Based Data
Store game data in Resources:
```gdscript
# item_data.gd
class_name ItemData extends Resource
@export var item_name: String
@export var icon: Texture2D
@export var price: int
```
```
---
## 🐛 Troubleshooting
### Issue: .cursorrules Not Loading
**Solutions:**
```bash
# 1. Check file location
ls -la .cursorrules # Project root
ls -la ~/.cursor/.cursorrules # Global
# 2. Verify file is UTF-8
file .cursorrules
# 3. Restart Cursor completely
# Cmd+Q (macOS) or Alt+F4 (Windows), then reopen
# 4. Check Cursor settings
# Settings > Features > Ensure "Custom Instructions" is enabled
```
### Issue: Rules Too Large (>200KB)
**Solutions:**
```bash
# Check file size
ls -lh .cursorrules
# Reduce size:
# 1. Use --enhance to create concise version
skill-seekers enhance output/django --mode LOCAL
# 2. Extract only essential sections
cat output/django/SKILL.md | head -n 1000 > .cursorrules
# 3. Use category-specific rules (split by directory)
cat output/django/references/models.md > models/.cursorrules
cat output/django/references/views.md > views/.cursorrules
```
### Issue: AI Not Using Rules
**Diagnostics:**
```
1. Ask Cursor: "What frameworks do you know about?"
- If it mentions your framework, rules are loaded
- If not, rules aren't loading
2. Test with specific prompt:
"Create a [Framework-specific concept]"
- Should use terminology from your docs
3. Check Cursor's response format:
- Does it match patterns from your docs?
- Does it mention framework-specific features?
```
**Solutions:**
- Restart Cursor
- Verify .cursorrules is in correct location
- Check file size (<200KB)
- Test with simpler rules first
### Issue: Inconsistent AI Responses
**Solutions:**
```markdown
# Add explicit instructions at top of .cursorrules:
# IMPORTANT: Always reference the patterns and examples below
# When suggesting code, use the exact patterns shown
# When explaining concepts, use the terminology defined here
# If you don't know something, say so - don't make up patterns
```

# Using Skill Seekers with LangChain
**Last Updated:** February 5, 2026
**Status:** Production Ready
**Difficulty:** Easy ⭐
---
## 🎯 The Problem
Building RAG (Retrieval-Augmented Generation) applications with LangChain requires high-quality, structured documentation for your vector stores. Manually scraping and chunking documentation is:
- **Time-Consuming** - Hours spent scraping docs and formatting them
- **Error-Prone** - Inconsistent chunking, missing metadata, broken references
- **Not Maintainable** - Documentation updates require re-scraping everything
**Example:**
> "When building a RAG chatbot for React documentation, you need to scrape 500+ pages, chunk them properly, add metadata, and load into a vector store. This typically takes 4-6 hours of manual work."
---
## ✨ The Solution
Use Skill Seekers as **essential preprocessing** before LangChain:
1. **Generate LangChain Documents** from any documentation source
2. **Pre-chunked and structured** with proper metadata
3. **Ready for vector stores** (Chroma, Pinecone, FAISS, etc.)
4. **One command** - scrape, chunk, format in minutes
**Result:**
Skill Seekers outputs JSON files with LangChain Document format, ready to load directly into your RAG pipeline.
---
## 🚀 Quick Start (5 Minutes)
### Prerequisites
- Python 3.10+
- LangChain installed: `pip install langchain langchain-community`
- OpenAI API key (for embeddings): `export OPENAI_API_KEY=sk-...`
### Installation
```bash
# Install Skill Seekers
pip install skill-seekers
# Verify installation
skill-seekers --version
```
### Generate LangChain Documents
```bash
# Example: React framework documentation
skill-seekers scrape --config configs/react.json
# Package as LangChain Documents
skill-seekers package output/react --target langchain
# Output: output/react-langchain.json
```
### Load into LangChain
```python
from langchain.schema import Document
from langchain.vectorstores import Chroma
from langchain.embeddings import OpenAIEmbeddings
import json
# Load documents
with open("output/react-langchain.json") as f:
docs_data = json.load(f)
# Convert to LangChain Documents
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
print(f"Loaded {len(documents)} documents")
# Create vector store
embeddings = OpenAIEmbeddings()
vectorstore = Chroma.from_documents(documents, embeddings)
# Query
results = vectorstore.similarity_search("How do I use React hooks?", k=3)
for doc in results:
print(f"\n{doc.metadata['category']}: {doc.page_content[:200]}...")
```
---
## 📖 Detailed Setup Guide
### Step 1: Choose Your Documentation Source
**Option A: Use Preset Config (Fastest)**
```bash
# Available presets: react, vue, django, fastapi, etc.
skill-seekers scrape --config configs/react.json
```
**Option B: From GitHub Repository**
```bash
# Scrape from GitHub repo (includes code + docs)
skill-seekers github --repo facebook/react --name react-skill
```
**Option C: Custom Documentation**
```bash
# Create custom config for your docs
skill-seekers scrape --config configs/my-docs.json
```
### Step 2: Generate LangChain Format
```bash
# Convert to LangChain Documents
skill-seekers package output/react --target langchain
# Output structure:
# output/react-langchain.json
# [
# {
# "page_content": "...",
# "metadata": {
# "source": "react",
# "category": "hooks",
# "file": "hooks.md",
# "type": "reference"
# }
# }
# ]
```
**What You Get:**
- ✅ Pre-chunked documents (semantic boundaries preserved)
- ✅ Rich metadata (source, category, file, type)
- ✅ Clean markdown (code blocks preserved)
- ✅ Ready for embeddings
### Step 3: Load into Vector Store
**Option 1: Chroma (Local, Persistent)**
```python
from langchain.vectorstores import Chroma
from langchain.embeddings import OpenAIEmbeddings
from langchain.schema import Document
import json
# Load documents
with open("output/react-langchain.json") as f:
docs_data = json.load(f)
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
# Create persistent Chroma store
embeddings = OpenAIEmbeddings()
vectorstore = Chroma.from_documents(
documents,
embeddings,
persist_directory="./chroma_db"
)
print(f"✅ {len(documents)} documents loaded into Chroma")
```
**Option 2: FAISS (Fast, In-Memory)**
```python
from langchain.vectorstores import FAISS
from langchain.embeddings import OpenAIEmbeddings
from langchain.schema import Document
import json
with open("output/react-langchain.json") as f:
docs_data = json.load(f)
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
embeddings = OpenAIEmbeddings()
vectorstore = FAISS.from_documents(documents, embeddings)
# Save for later use
vectorstore.save_local("faiss_index")
print(f"✅ {len(documents)} documents loaded into FAISS")
```
**Option 3: Pinecone (Cloud, Scalable)**
```python
from langchain.vectorstores import Pinecone as LangChainPinecone
from langchain.embeddings import OpenAIEmbeddings
from langchain.schema import Document
import json
import pinecone
# Initialize Pinecone
pinecone.init(api_key="your-api-key", environment="us-west1-gcp")
index_name = "react-docs"
if index_name not in pinecone.list_indexes():
pinecone.create_index(index_name, dimension=1536)
# Load documents
with open("output/react-langchain.json") as f:
docs_data = json.load(f)
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
# Upload to Pinecone
embeddings = OpenAIEmbeddings()
vectorstore = LangChainPinecone.from_documents(
documents,
embeddings,
index_name=index_name
)
print(f"✅ {len(documents)} documents uploaded to Pinecone")
```
### Step 4: Build RAG Chain
```python
from langchain.chains import RetrievalQA
from langchain.chat_models import ChatOpenAI
# Create retriever from vector store
retriever = vectorstore.as_retriever(
search_type="similarity",
search_kwargs={"k": 3}
)
# Create RAG chain
llm = ChatOpenAI(model_name="gpt-4", temperature=0)
qa_chain = RetrievalQA.from_chain_type(
llm=llm,
chain_type="stuff",
retriever=retriever,
return_source_documents=True
)
# Query
query = "How do I use React hooks?"
result = qa_chain({"query": query})
print(f"Answer: {result['result']}")
print(f"\nSources:")
for doc in result['source_documents']:
print(f" - {doc.metadata['category']}: {doc.metadata['file']}")
```
---
## 🎨 Advanced Usage
### Filter by Metadata
```python
# Search only in specific categories
retriever = vectorstore.as_retriever(
search_type="similarity",
search_kwargs={
"k": 5,
"filter": {"category": "hooks"}
}
)
```
### Custom Metadata Enrichment
```python
# Add custom metadata before loading
for doc_data in docs_data:
doc_data["metadata"]["indexed_at"] = datetime.now().isoformat()
doc_data["metadata"]["version"] = "18.2.0"
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
```
### Multi-Source Documentation
```python
# Combine multiple documentation sources
sources = ["react", "vue", "angular"]
all_documents = []
for source in sources:
with open(f"output/{source}-langchain.json") as f:
docs_data = json.load(f)
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
all_documents.extend(documents)
# Create unified vector store
vectorstore = Chroma.from_documents(all_documents, embeddings)
print(f"✅ Loaded {len(all_documents)} documents from {len(sources)} sources")
```
---
## 💡 Best Practices
### 1. Start with Presets
Use tested configurations to avoid scraping issues:
```bash
ls configs/ # See available presets
skill-seekers scrape --config configs/django.json
```
### 2. Test Queries Before Full Pipeline
```python
# Quick test with similarity search
results = vectorstore.similarity_search("your query", k=3)
for doc in results:
print(f"{doc.metadata['category']}: {doc.page_content[:100]}")
```
### 3. Use Persistent Storage
```python
# Save Chroma DB for reuse
vectorstore = Chroma.from_documents(
documents,
embeddings,
persist_directory="./chroma_db" # ← Persists to disk
)
# Later: load existing DB
vectorstore = Chroma(
persist_directory="./chroma_db",
embedding_function=embeddings
)
```
### 4. Monitor Token Usage
```python
# Check document sizes before embedding
total_tokens = sum(len(doc["page_content"].split()) for doc in docs_data)
print(f"Estimated tokens: {total_tokens * 1.3:.0f}") # Rough estimate
```
---
## 🔥 Real-World Example
### Building a React Documentation Chatbot
**Step 1: Generate Documents**
```bash
# Scrape React docs
skill-seekers scrape --config configs/react.json
# Convert to LangChain format
skill-seekers package output/react --target langchain
```
**Step 2: Create Vector Store**
```python
from langchain.vectorstores import Chroma
from langchain.embeddings import OpenAIEmbeddings
from langchain.schema import Document
from langchain.chains import ConversationalRetrievalChain
from langchain.chat_models import ChatOpenAI
from langchain.memory import ConversationBufferMemory
import json
# Load documents
with open("output/react-langchain.json") as f:
docs_data = json.load(f)
documents = [
Document(page_content=doc["page_content"], metadata=doc["metadata"])
for doc in docs_data
]
# Create vector store
embeddings = OpenAIEmbeddings()
vectorstore = Chroma.from_documents(
documents,
embeddings,
persist_directory="./react_chroma"
)
print(f"✅ Loaded {len(documents)} React documentation chunks")
```
**Step 3: Build Conversational RAG**
```python
# Create conversational chain with memory
memory = ConversationBufferMemory(
memory_key="chat_history",
return_messages=True
)
qa_chain = ConversationalRetrievalChain.from_llm(
llm=ChatOpenAI(model_name="gpt-4", temperature=0),
retriever=vectorstore.as_retriever(search_kwargs={"k": 3}),
memory=memory,
return_source_documents=True
)
# Chat loop
while True:
query = input("\nYou: ")
if query.lower() in ['quit', 'exit']:
break
result = qa_chain({"question": query})
print(f"\nAssistant: {result['answer']}")
print(f"\nSources:")
for doc in result['source_documents']:
print(f" - {doc.metadata['category']}: {doc.metadata['file']}")
```
**Result:**
- Complete React documentation in 100-200 documents
- Sub-second query responses
- Source attribution for every answer
- Conversational context maintained
---
## 🐛 Troubleshooting
### Issue: Too Many Documents
**Solution:** Filter by category or split into multiple indexes
```python
# Filter specific categories
hooks_docs = [
doc for doc in docs_data
if doc["metadata"]["category"] == "hooks"
]
```
### Issue: Large Documents
**Solution:** Documents are already chunked, but you can re-chunk if needed
```python
from langchain.text_splitter import RecursiveCharacterTextSplitter
text_splitter = RecursiveCharacterTextSplitter(
chunk_size=1000,
chunk_overlap=200
)
split_documents = text_splitter.split_documents(documents)
```
### Issue: Missing Dependencies
**Solution:** Install LangChain components
```bash
pip install langchain langchain-community langchain-openai
pip install chromadb # For Chroma
pip install faiss-cpu # For FAISS
```

# Using Skill Seekers with LlamaIndex
**Last Updated:** February 5, 2026
**Status:** Production Ready
**Difficulty:** Easy ⭐
---
## 🎯 The Problem
Building knowledge bases and query engines with LlamaIndex requires well-structured documentation. Manually preparing documents is:
- **Labor-Intensive** - Scraping, chunking, and formatting takes hours
- **Inconsistent** - Manual processes lead to quality variations
- **Hard to Update** - Documentation changes require complete rework
**Example:**
> "When building a LlamaIndex query engine for FastAPI documentation, you need to extract 300+ pages, structure them properly, and maintain consistent metadata. This typically takes 3-5 hours."
---
## ✨ The Solution
Use Skill Seekers as **essential preprocessing** before LlamaIndex:
1. **Generate LlamaIndex Nodes** from any documentation source
2. **Pre-structured with IDs** and rich metadata
3. **Ready for indexes** (VectorStoreIndex, TreeIndex, KeywordTableIndex)
4. **One command** - complete documentation in minutes
**Result:**
Skill Seekers outputs JSON files with LlamaIndex Node format, ready to build indexes and query engines.
---
## 🚀 Quick Start (5 Minutes)
### Prerequisites
- Python 3.10+
- LlamaIndex installed: `pip install llama-index`
- OpenAI API key (for embeddings): `export OPENAI_API_KEY=sk-...`
### Installation
```bash
# Install Skill Seekers
pip install skill-seekers
# Verify installation
skill-seekers --version
```
### Generate LlamaIndex Nodes
```bash
# Example: Django framework documentation
skill-seekers scrape --config configs/django.json
# Package as LlamaIndex Nodes
skill-seekers package output/django --target llama-index
# Output: output/django-llama-index.json
```
### Build Query Engine
```python
from llama_index.core.schema import TextNode
from llama_index.core import VectorStoreIndex
import json
# Load nodes
with open("output/django-llama-index.json") as f:
nodes_data = json.load(f)
# Convert to LlamaIndex Nodes
nodes = [
TextNode(
text=node["text"],
metadata=node["metadata"],
id_=node["id_"]
)
for node in nodes_data
]
print(f"Loaded {len(nodes)} nodes")
# Create index
index = VectorStoreIndex(nodes)
# Create query engine
query_engine = index.as_query_engine()
# Query
response = query_engine.query("How do I create a Django model?")
print(response)
```
---
## 📖 Detailed Setup Guide
### Step 1: Choose Your Documentation Source
**Option A: Use Preset Config (Fastest)**
```bash
# Available presets: django, fastapi, vue, etc.
skill-seekers scrape --config configs/django.json
```
**Option B: From GitHub Repository**
```bash
# Scrape from GitHub repo
skill-seekers github --repo django/django --name django-skill
```
**Option C: Custom Documentation**
```bash
# Create custom config
skill-seekers scrape --config configs/my-docs.json
```
### Step 2: Generate LlamaIndex Format
```bash
# Convert to LlamaIndex Nodes
skill-seekers package output/django --target llama-index
# Output structure:
# output/django-llama-index.json
# [
# {
# "text": "...",
# "metadata": {
# "source": "django",
# "category": "models",
# "file": "models.md"
# },
# "id_": "unique-hash-id",
# "embedding": null
# }
# ]
```
**What You Get:**
- ✅ Pre-structured nodes with unique IDs
- ✅ Rich metadata (source, category, file, type)
- ✅ Clean text (code blocks preserved)
- ✅ Ready for indexing
### Step 3: Create Vector Store Index
```python
from llama_index.core.schema import TextNode
from llama_index.core import VectorStoreIndex, StorageContext
from llama_index.core.storage.docstore import SimpleDocumentStore
from llama_index.core.storage.index_store import SimpleIndexStore
from llama_index.core.vector_stores import SimpleVectorStore
import json
# Load nodes
with open("output/django-llama-index.json") as f:
nodes_data = json.load(f)
nodes = [
TextNode(
text=node["text"],
metadata=node["metadata"],
id_=node["id_"]
)
for node in nodes_data
]
# Create index
index = VectorStoreIndex(nodes)
# Persist for later use
index.storage_context.persist(persist_dir="./storage")
print(f"✅ Index created with {len(nodes)} nodes")
```
**Load Persisted Index:**
```python
from llama_index.core import load_index_from_storage, StorageContext
# Load from disk
storage_context = StorageContext.from_defaults(persist_dir="./storage")
index = load_index_from_storage(storage_context)
print("✅ Index loaded from storage")
```
### Step 4: Create Query Engine
**Basic Query Engine:**
```python
# Create query engine
query_engine = index.as_query_engine(
similarity_top_k=3, # Return top 3 relevant chunks
response_mode="compact"
)
# Query
response = query_engine.query("How do I create a Django model?")
print(response)
```
**Chat Engine (Conversational):**
```python
from llama_index.core.chat_engine import CondenseQuestionChatEngine
# Create chat engine with memory
chat_engine = index.as_chat_engine(
chat_mode="condense_question",
verbose=True
)
# Chat
response = chat_engine.chat("Tell me about Django models")
print(response)
# Follow-up (maintains context)
response = chat_engine.chat("How do I add fields?")
print(response)
```
---
## 🎨 Advanced Usage
### Custom Index Types
**Tree Index (For Summarization):**
```python
from llama_index.core import TreeIndex
tree_index = TreeIndex(nodes)
query_engine = tree_index.as_query_engine()
# Better for summarization queries
response = query_engine.query("Summarize Django's ORM capabilities")
```
**Keyword Table Index (For Keyword Search):**
```python
from llama_index.core import KeywordTableIndex
keyword_index = KeywordTableIndex(nodes)
query_engine = keyword_index.as_query_engine()
# Better for keyword-based queries
response = query_engine.query("foreign key relationships")
```
### Query with Filters
```python
from llama_index.core.vector_stores import MetadataFilters, ExactMatchFilter
# Filter by category
filters = MetadataFilters(
filters=[
ExactMatchFilter(key="category", value="models")
]
)
query_engine = index.as_query_engine(
similarity_top_k=3,
filters=filters
)
# Only searches in "models" category
response = query_engine.query("How do relationships work?")
```
### Custom Retrieval
```python
from llama_index.core.retrievers import VectorIndexRetriever
# Custom retriever with specific settings
retriever = VectorIndexRetriever(
index=index,
similarity_top_k=5,
)
# Get source nodes
nodes = retriever.retrieve("django models")
for node in nodes:
print(f"Score: {node.score:.3f}")
print(f"Category: {node.metadata['category']}")
print(f"Text: {node.text[:100]}...\n")
```
### Multi-Source Knowledge Base
```python
# Combine multiple documentation sources
sources = ["django", "fastapi", "flask"]
all_nodes = []
for source in sources:
with open(f"output/{source}-llama-index.json") as f:
nodes_data = json.load(f)
nodes = [
TextNode(
text=node["text"],
metadata=node["metadata"],
id_=node["id_"]
)
for node in nodes_data
]
all_nodes.extend(nodes)
# Create unified index
index = VectorStoreIndex(all_nodes)
print(f"✅ Created index with {len(all_nodes)} nodes from {len(sources)} sources")
```
---
## 💡 Best Practices
### 1. Persist Your Indexes
```python
# Save to avoid re-indexing
index.storage_context.persist(persist_dir="./storage")
# Load when needed
storage_context = StorageContext.from_defaults(persist_dir="./storage")
index = load_index_from_storage(storage_context)
```
### 2. Use Streaming for Long Responses
```python
query_engine = index.as_query_engine(
streaming=True
)
response = query_engine.query("Explain Django in detail")
for text in response.response_gen:
print(text, end="", flush=True)
```
### 3. Add Response Synthesis
```python
from llama_index.core.response_synthesizers import ResponseMode
query_engine = index.as_query_engine(
response_mode=ResponseMode.TREE_SUMMARIZE, # Better for long docs
similarity_top_k=5
)
```
### 4. Monitor Performance
```python
import time
start = time.time()
response = query_engine.query("your question")
elapsed = time.time() - start
print(f"Query took {elapsed:.2f}s")
print(f"Used {len(response.source_nodes)} source nodes")
```

## 🔥 Real-World Example
### Building a FastAPI Documentation Assistant
**Step 1: Generate Nodes**
```bash
# Scrape FastAPI docs
skill-seekers scrape --config configs/fastapi.json
# Convert to LlamaIndex format
skill-seekers package output/fastapi --target llama-index
```
**Step 2: Build Index and Query Engine**
```python
from llama_index.core.schema import TextNode
from llama_index.core import VectorStoreIndex
from llama_index.core.chat_engine import CondenseQuestionChatEngine
import json
# Load nodes
with open("output/fastapi-llama-index.json") as f:
nodes_data = json.load(f)
nodes = [
TextNode(
text=node["text"],
metadata=node["metadata"],
id_=node["id_"]
)
for node in nodes_data
]
# Create index
index = VectorStoreIndex(nodes)
index.storage_context.persist(persist_dir="./fastapi_index")
print(f"✅ FastAPI index created with {len(nodes)} nodes")
# Create chat engine
chat_engine = index.as_chat_engine(
chat_mode="condense_question",
verbose=True
)
# Interactive loop
print("\n🤖 FastAPI Documentation Assistant")
print("Ask me anything about FastAPI (type 'quit' to exit)\n")
while True:
user_input = input("You: ").strip()
if user_input.lower() in ['quit', 'exit', 'q']:
print("👋 Goodbye!")
break
if not user_input:
continue
response = chat_engine.chat(user_input)
print(f"\nAssistant: {response}\n")
# Show sources
print("Sources:")
for node in response.source_nodes:
cat = node.metadata.get('category', 'unknown')
file = node.metadata.get('file', 'unknown')
print(f" - {cat} ({file})")
print()
```
**Result:**
- Complete FastAPI documentation indexed
- Conversational interface with memory
- Source attribution for transparency
- Instant responses (<1 second)
---
## 🐛 Troubleshooting
### Issue: Index Too Large
**Solution:** Use hybrid indexing or split by category
```python
# Create separate indexes per category
categories = set(node["metadata"]["category"] for node in nodes_data)
indexes = {}
for category in categories:
cat_nodes = [
TextNode(**node)
for node in nodes_data
if node["metadata"]["category"] == category
]
indexes[category] = VectorStoreIndex(cat_nodes)
```
### Issue: Slow Queries
**Solution:** Reduce similarity_top_k or use caching
```python
query_engine = index.as_query_engine(
similarity_top_k=2, # Reduce from 3 to 2
)
```
### Issue: Missing Dependencies
**Solution:** Install LlamaIndex components
```bash
pip install llama-index llama-index-core
pip install llama-index-llms-openai # For OpenAI LLM
pip install llama-index-embeddings-openai # For OpenAI embeddings
```

# Using Skill Seekers with Pinecone
**Last Updated:** February 5, 2026
**Status:** Production Ready
**Difficulty:** Easy ⭐
---
## 🎯 The Problem
Building production-grade vector search applications requires:
- **Scalable Vector Database** - Handle millions of embeddings efficiently
- **Low Latency** - Sub-100ms query response times
- **High Availability** - 99.9% uptime for production apps
- **Easy Integration** - Works with any embedding model
**Example:**
> "When building a customer support bot with RAG, you need to search across 500k+ documentation chunks in <50ms. Managing your own vector database means dealing with scaling, replication, and performance optimization."
---
## ✨ The Solution
Use Skill Seekers to **prepare documentation for Pinecone**:
1. **Generate structured documents** from any source
2. **Create embeddings** with your preferred model (OpenAI, Cohere, etc.)
3. **Upsert to Pinecone** with rich metadata for filtering
4. **Query with context** - Full metadata preserved for filtering and routing
**Result:**
Skill Seekers outputs JSON format ready for Pinecone upsert with all metadata intact.
---
## 🚀 Quick Start (10 Minutes)
### Prerequisites
- Python 3.10+
- Pinecone account (free tier available)
- Embedding model API key (OpenAI or Cohere recommended)
### Installation
```bash
# Install Skill Seekers

```
### Upsert to Pinecone
```python
from pinecone import Pinecone, ServerlessSpec
from openai import OpenAI
import json
# Initialize clients
pc = Pinecone(api_key="your-pinecone-api-key")
openai_client = OpenAI()
# Create index (first time only)
index_name = "react-docs"
if index_name not in pc.list_indexes().names():
pc.create_index(
name=index_name,
dimension=1536, # OpenAI ada-002 dimension
metric="cosine",
spec=ServerlessSpec(cloud="aws", region="us-east-1")
)
# Connect to index
index = pc.Index(index_name)
# Load documents
with open("output/react-langchain.json") as f:
documents = json.load(f)
# Create embeddings and upsert
vectors = []
for i, doc in enumerate(documents):
# Generate embedding
response = openai_client.embeddings.create(
model="text-embedding-ada-002",
input=doc["page_content"]
)
embedding = response.data[0].embedding
# Prepare vector with metadata
vectors.append({
"id": f"doc_{i}",
"values": embedding,
"metadata": {
"text": doc["page_content"][:1000], # Store snippet
"source": doc["metadata"]["source"],
"category": doc["metadata"]["category"],
"file": doc["metadata"]["file"],
"type": doc["metadata"]["type"]
}
})
# Batch upsert every 100 vectors
if len(vectors) >= 100:
index.upsert(vectors=vectors)
vectors = []
print(f"Upserted {i + 1} documents...")
# Upsert remaining
if vectors:
index.upsert(vectors=vectors)
print(f"✅ Upserted {len(documents)} documents to Pinecone")
```
### Query Pinecone
```python
# Query with filters
query = "How do I use hooks in React?"
# Generate query embedding
response = openai_client.embeddings.create(
model="text-embedding-ada-002",
input=query
)
query_embedding = response.data[0].embedding
# Search with metadata filter
results = index.query(
vector=query_embedding,
top_k=3,
include_metadata=True,
filter={"category": {"$eq": "hooks"}} # Filter by category
)
# Display results
for match in results["matches"]:
print(f"Score: {match['score']:.3f}")
print(f"Category: {match['metadata']['category']}")
print(f"Text: {match['metadata']['text'][:200]}...")
print()
```
---
## 📖 Detailed Setup Guide
### Step 1: Create Pinecone Index
```python
from pinecone import Pinecone, ServerlessSpec
pc = Pinecone(api_key="your-api-key")
# Choose dimensions based on your embedding model:
# - OpenAI ada-002: 1536
# - OpenAI text-embedding-3-small: 1536
# - OpenAI text-embedding-3-large: 3072
# - Cohere embed-english-v3.0: 1024
pc.create_index(
name="my-docs",
dimension=1536, # Match your embedding model
metric="cosine",
spec=ServerlessSpec(
cloud="aws",
region="us-east-1" # Choose closest region
)
)
```
**Available regions:**
- AWS: us-east-1, us-west-2, eu-west-1, ap-southeast-1
- GCP: us-central1, europe-west1, asia-southeast1
- Azure: eastus2, westeurope
### Step 2: Generate Skill Seekers Documents
**Option A: Documentation Website**
```bash
skill-seekers scrape --config configs/django.json
skill-seekers package output/django --target langchain
```
**Option B: GitHub Repository**
```bash
skill-seekers github --repo django/django --name django
skill-seekers package output/django --target langchain
```
**Option C: Local Codebase**
```bash
skill-seekers analyze --directory /path/to/repo
skill-seekers package output/codebase --target langchain
```
### Step 3: Create Embeddings Strategy
**Strategy 1: OpenAI (Recommended)**
```python
from openai import OpenAI
client = OpenAI()
def create_embedding(text: str) -> list[float]:
response = client.embeddings.create(
model="text-embedding-ada-002",
input=text
)
return response.data[0].embedding
# Cost: ~$0.0001 per 1K tokens
# Speed: ~1000 docs/minute
# Quality: Excellent for most use cases
```
**Strategy 2: Cohere**
```python
import cohere
co = cohere.Client("your-cohere-api-key")
def create_embedding(text: str) -> list[float]:
response = co.embed(
texts=[text],
model="embed-english-v3.0",
input_type="search_document"
)
return response.embeddings[0]
# Cost: ~$0.0001 per 1K tokens
# Speed: ~1000 docs/minute
# Quality: Excellent, especially for semantic search
```
**Strategy 3: Local Model (SentenceTransformers)**
```python
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
def create_embedding(text: str) -> list[float]:
return model.encode(text).tolist()
# Cost: Free
# Speed: ~500-1000 docs/minute (CPU)
# Quality: Good for smaller datasets
# Note: Dimension is 384 for all-MiniLM-L6-v2
```
### Step 4: Batch Upsert Pattern
```python
import json
from typing import List, Dict
from tqdm import tqdm
def batch_upsert_documents(
index,
documents_path: str,

)
return results["matches"]
# Example queries

print(f"Text: {match['metadata']['text'][:200]}...")
print()
```

## 🎨 Advanced Usage
### Hybrid Search (Keyword + Semantic)
```python
# Pinecone sparse-dense hybrid search
from pinecone_text.sparse import BM25Encoder
# Initialize BM25 encoder
bm25 = BM25Encoder()
bm25.fit(documents) # Fit on your corpus
def hybrid_search(query: str, top_k: int = 5):
# Dense embedding
dense_embedding = create_embedding(query)
# Sparse embedding (BM25)
sparse_embedding = bm25.encode_queries(query)
# Hybrid query
results = index.query(
vector=dense_embedding,
sparse_vector=sparse_embedding,
top_k=top_k,
include_metadata=True
)
return results["matches"]
```
### Namespace Management
```python
# Organize documents by namespace
namespaces = {
"stable": documents_v1,
"beta": documents_v2,
"archived": old_documents
}
for ns, docs in namespaces.items():
vectors = prepare_vectors(docs)
index.upsert(vectors=vectors, namespace=ns)
# Query specific namespace
results = index.query(
vector=query_embedding,
top_k=5,
namespace="stable" # Only query stable docs
)
```
### Metadata Filtering Patterns
```python
# Exact match
filter={"category": {"$eq": "api"}}
# Multiple values (OR)
filter={"category": {"$in": ["api", "guides"]}}
# Exclude
filter={"type": {"$ne": "deprecated"}}
# Range (for numeric metadata)
filter={"version": {"$gte": 2.0}}
# Multiple conditions (AND)
filter={
"$and": [
{"category": {"$eq": "api"}},
{"version": {"$gte": 2.0}}
]
}
```
### RAG Pipeline Integration
```python
from openai import OpenAI
openai_client = OpenAI()
def rag_query(question: str, top_k: int = 3):
"""Complete RAG pipeline with Pinecone."""
# 1. Retrieve relevant documents
query_embedding = create_embedding(question)
results = index.query(
vector=query_embedding,
top_k=top_k,
include_metadata=True
)
# 2. Build context from results
context_parts = []
for match in results["matches"]:
context_parts.append(
f"[{match['metadata']['category']}] "
f"{match['metadata']['text']}"
)
context = "\n\n".join(context_parts)
# 3. Generate answer with LLM
response = openai_client.chat.completions.create(
model="gpt-4",
messages=[
{
"role": "system",
"content": "Answer based on the provided context."
},
{
"role": "user",
"content": f"Context:\n{context}\n\nQuestion: {question}"
}
]
)
return {
"answer": response.choices[0].message.content,
"sources": [
{
"category": m["metadata"]["category"],
"file": m["metadata"]["file"],
"score": m["score"]
}
for m in results["matches"]
]
}
# Usage
result = rag_query("How do I create a React component?")
print(f"Answer: {result['answer']}\n")
print("Sources:")
for source in result["sources"]:
print(f" - {source['category']} ({source['file']}) - Score: {source['score']:.3f}")
```

## 💡 Best Practices
### 1. Choose Right Index Configuration
```python
# Serverless (recommended for most cases)
spec=ServerlessSpec(
cloud="aws",
region="us-east-1" # Choose closest to your users
)
# Pod-based (for high throughput, dedicated resources)
spec=PodSpec(
environment="us-east1-gcp",
pod_type="p1.x1", # Small: p1.x1, Medium: p1.x2, Large: p2.x1
pods=1,
replicas=1
)
```
### 2. Optimize Metadata Storage
```python
# Store only essential metadata in Pinecone (max 40KB per vector)
# Keep full text elsewhere (database, object storage)
metadata = {
"text": doc["page_content"][:1000], # Snippet only
"full_text_id": str(i), # Reference to full text
"category": doc["metadata"]["category"],
"source": doc["metadata"]["source"],
# Don't store: full page_content, images, binary data
}
```
### 3. Use Namespaces for Multi-Tenancy
```python
# Per-customer namespaces
namespace = f"customer_{customer_id}"
index.upsert(vectors=vectors, namespace=namespace)
# Query only customer's data
results = index.query(
vector=query_embedding,
namespace=namespace,
top_k=5
)
```
### 4. Monitor Index Performance
```python
# Check index stats
stats = index.describe_index_stats()
print(f"Total vectors: {stats['total_vector_count']}")
print(f"Dimension: {stats['dimension']}")
print(f"Namespaces: {stats.get('namespaces', {})}")
# Monitor query latency
import time
start = time.time()
results = index.query(vector=query_embedding, top_k=5)
latency = time.time() - start
print(f"Query latency: {latency*1000:.2f}ms")
```
### 5. Handle Updates Efficiently
```python
# Update existing vectors (upsert with same ID)
index.upsert(vectors=[{
"id": "doc_123",
"values": new_embedding,
"metadata": updated_metadata
}])
# Delete obsolete vectors
index.delete(ids=["doc_123", "doc_456"])
# Delete by metadata filter
index.delete(filter={"category": {"$eq": "deprecated"}})
```

"""Ingest Skill Seekers documentation."""
with open(docs_path) as f:
documents = json.load(f)
vectors = []
for i, doc in enumerate(documents):
# Create embedding
response = self.openai.embeddings.create(

## 🐛 Troubleshooting
### Issue: Dimension Mismatch Error
**Problem:** "Dimension mismatch: expected 1536, got 384"
**Solution:** Ensure embedding model dimension matches index
```python
# Check your embedding model dimension
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
print(f"Model dimension: {model.get_sentence_embedding_dimension()}") # 384
# Create index with correct dimension
pc.create_index(name="my-index", dimension=384, ...)
```
### Issue: Rate Limit Errors
**Problem:** "Rate limit exceeded"
**Solution:** Add retry logic and batching
```python
import time
from tenacity import retry, wait_exponential, stop_after_attempt
@retry(wait=wait_exponential(multiplier=1, min=2, max=10), stop=stop_after_attempt(3))
def upsert_with_retry(index, vectors):
return index.upsert(vectors=vectors)
# Use smaller batches
batch_size = 50 # Reduce from 100
```
### Issue: High Query Latency
**Solutions:**
```python
# 1. Reduce top_k
results = index.query(vector=query_embedding, top_k=3) # Instead of 10
# 2. Use metadata filtering to reduce search space
filter={"category": {"$eq": "api"}}
# 3. Use namespaces
namespace="high_priority_docs"
# 4. Consider pod-based index for consistent low latency
spec=PodSpec(environment="us-east1-gcp", pod_type="p1.x2")
```
### Issue: Missing Metadata
**Problem:** Metadata not returned in results
**Solution:** Enable metadata in query
```python
results = index.query(
vector=query_embedding,
top_k=5,
include_metadata=True # CRITICAL
)
```

| Cohere | embed-english-v3.0 | $0.10 | Fast |
| Local | SentenceTransformers | Free | Medium |
**Recommendation:** OpenAI text-embedding-3-small (best quality/cost ratio)
### Pinecone Costs
**Serverless (pay per use):**
- Storage: $0.01 per GB/month
- Reads: $0.025 per 100k read units
- Writes: $0.50 per 100k write units
**Pod-based (fixed cost):**
- p1.x1: ~$70/month (1GB storage, 100 QPS)
- p1.x2: ~$140/month (2GB storage, 200 QPS)
- p2.x1: ~$280/month (4GB storage, 400 QPS)
**Example costs for 100k documents:**
- Storage: ~250MB = $0.0025/month
- Writes: 100k = $0.50 one-time
- Reads: 100k queries = $0.025/month
