Data Processing

Context Construction

Intelligent Context Selection

models:
  - name: "context-aware-model"
    provider: "anthropic"
    model: "claude-3-sonnet"
    apiKey: "${ANTHROPIC_API_KEY}"
    roles: ["chat"]
    defaultCompletionOptions:
      temperature: 0.6
      maxTokens: 8000

Context selection strategies:

• Relevance Scoring: Calculate file relevance
• Priority Ordering: Order by importance
• Size Limiting: Control total context amount
• Dynamic Adjustment: Adjust based on task

Context Compression

Compression techniques:

• Summary Generation: Extract key information
• Deduplication: Remove duplicate content
• Priority Filtering: Keep only important information
• Hierarchical: Organize context in layers

Data Indexing

Vector Indexing

models:
  # Embedding model for indexing
  - name: "embedding-index"
    provider: "openai"
    model: "text-embedding-3-large"
    apiKey: "${OPENAI_API_KEY}"
    roles: ["embed"]

  # Chat model uses indexed data
  - name: "indexed-chat"
    provider: "openai"
    model: "gpt-4"
    apiKey: "${OPENAI_API_KEY}"
    roles: ["chat"]
    defaultCompletionOptions:
      temperature: 0.7
      maxTokens: 4000

Indexing strategies:

• Code Block Indexing: Index functions, classes, etc.
• Documentation Indexing: Index comments and docs
• Dependency Indexing: Index imports and dependencies
• Real-time Updates: Update index on file changes

Symbol Indexing

Symbol types:

• Functions: Function definitions and calls
• Classes: Class definitions and inheritance
• Variables: Variable declarations and usage
• Types: Type definitions and references

Data Usage

RAG (Retrieval-Augmented Generation)

models:
  # Embedding model
  - name: "rag-embeddings"
    provider: "openai"
    model: "text-embedding-3-large"
    apiKey: "${OPENAI_API_KEY}"
    roles: ["embed"]

  # Reranking model
  - name: "rag-rerank"
    provider: "cohere"
    model: "rerank-english-v3.0"
    apiKey: "${COHERE_API_KEY}"
    roles: ["rerank"]

  # Generation model
  - name: "rag-generation"
    provider: "openai"
    model: "gpt-4"
    apiKey: "${OPENAI_API_KEY}"
    roles: ["chat"]
    defaultCompletionOptions:
      temperature: 0.7
      maxTokens: 4000

RAG workflow:

1. Query Embedding: Vectorize user question
2. Similarity Search: Retrieve relevant code and docs
3. Result Reranking: Optimize retrieval result order
4. Context Enhancement: Add retrieval results to context
5. Generate Answer: Generate response based on enhanced context

Code Search

Semantic Search

models:
  - name: "semantic-search"
    provider: "openai"
    model: "text-embedding-3-large"
    apiKey: "${OPENAI_API_KEY}"
    roles: ["embed"]

Search capabilities:

• Natural Language Queries: Describe needs in natural language
• Code Snippet Search: Find similar code
• Feature Search: Search code by functionality
• Cross-Project Search: Search across multiple projects

Exact Search

Traditional search methods:

• Text Matching: Exact text search
• Regular Expressions: Pattern matching
• Symbol Lookup: Search by symbol name
• Reference Finding: Find symbol references

Data Security

Privacy Protection

Configure privacy protection:

• Local Processing: Prioritize local models
• Data Filtering: Filter sensitive information
• Encrypted Transmission: Use HTTPS/TLS
• Access Control: Limit data access

Local Model Configuration

models:
  # Use local models to protect privacy
  - name: "private-assistant"
    provider: "ollama"
    model: "llama2"
    apiBase: "http://localhost:11434"
    roles: ["chat"]
    defaultCompletionOptions:
      temperature: 0.7
      maxTokens: 2000

Local model advantages:

• Complete Privacy: Data stays local
• No Network Dependency: Work offline
• Cost Savings: No API call fees
• Full Control: Complete data control

Best Practices

1. Data Organization

• Keep project structure clear
• Use meaningful naming
• Add sufficient comments and documentation
• Maintain updated README

2. Context Management

• Regularly clean irrelevant files
• Optimize file sizes
• Organize dependencies properly
• Use .gitignore to exclude irrelevant files

3. Performance Optimization

• Enable incremental indexing
• Use efficient data structures
• Implement caching strategies
• Limit context size

4. Security Considerations

• Use local models for sensitive data
• Configure data filtering rules
• Regularly review data access
• Comply with data protection regulations
