Claude Code Knowledge Management System (CCKMS)

Overview

A state-of-the-art knowledge management system designed specifically for Claude Code to capture, store, and retrieve CI troubleshooting lessons learned across multiple sessions.

Architecture

1. Knowledge Storage Layer

.claude/knowledge/

│   └── YYYY-MM-DD_HHMMSS_analysis.json
├── patterns/          # Identified patterns and recurring issues
│   ├── failure_patterns.json
│   └── solution_patterns.json

2. Data Model

Session Record Schema

{

3. Knowledge Capture Integration

TaskMaster AI Integration

# Enhanced session completion with knowledge capture
def complete_session_with_knowledge_capture(session_data):
    # Extract lessons learned
    lessons = extract_lessons_learned(session_data)
    
    # Identify patterns
    patterns = identify_solution_patterns(session_data)
    
    # Store knowledge
    knowledge_record = create_knowledge_record(
        session_data=session_data,
        lessons=lessons,
        patterns=patterns
    )
    
    # Update knowledge base
    store_knowledge_record(knowledge_record)
    
    # Update pattern database
    update_pattern_database(patterns)
    
    return knowledge_record

4. Semantic Search & Retrieval

Embedding-Based Search

  • Use lightweight embeddings (e.g., sentence-transformers/all-MiniLM-L6-v2)
  • Store embeddings locally for fast retrieval
  • Semantic similarity matching for finding relevant past solutions

Hybrid Search Strategy

def search_knowledge_base(query, context=None):
    # 1. Keyword search for exact matches
    keyword_results = keyword_search(query)
    
    # 2. Semantic search for similar issues
    semantic_results = semantic_search(query, top_k=5)
    
    # 3. Context-aware filtering
    if context:
        results = filter_by_context(
            keyword_results + semantic_results, 
            context
        )
    
    # 4. Rank by relevance and recency
    return rank_results(results)

5. Pattern Recognition & Learning

Automatic Pattern Detection

  • Analyze successful resolution sequences
  • Identify recurring failure types and solutions
  • Build solution templates for common issues

Pattern Categories

  • Failure Patterns: Common CI failure types and causes
  • Solution Patterns: Proven resolution approaches
  • Context Patterns: Environment-specific considerations
  • Temporal Patterns: Time-based correlations (CI load, etc.)

6. Context Restoration Workflow

Session Restart Protocol

# 1. Quick knowledge scan
CCKMS_scan_recent_sessions()

# 2. Context-aware retrieval
CCKMS_find_similar_issues(current_branch, current_failures)

# 3. Pattern matching
CCKMS_suggest_solutions(failure_patterns, historical_success)

# 4. Integration with existing workflow
TaskMaster_integrate_historical_context(knowledge_results)

Implementation Tools

Core Components

  1. File-based Storage: JSON files for persistence
  2. Embedding Engine: Local sentence transformers
  3. Search Index: Inverted index for keywords

Usage Workflow

Knowledge Capture (End of Session)

  1. Automatic: Extract data from TaskMaster session
  2. Manual: Add specific insights and lessons learned
  3. Validation: Ensure quality and completeness
  4. Storage: Persist to knowledge base with embeddings

Knowledge Retrieval (Start of Session)

  1. Context Analysis: Understand current situation
  2. Similarity Search: Find relevant past sessions
  3. Pattern Matching: Identify applicable solutions
  4. Recommendation: Suggest approaches based on history

Continuous Learning

  1. Success Analysis: What approaches worked?
  2. Failure Analysis: What approaches failed?
  3. Pattern Evolution: Update patterns based on new data
  4. Knowledge Pruning: Remove outdated information
