Your personal coding intelligence that learns from both successes AND failures. Claude Cache captures your complete problem-solving journey - what works, what doesn't, and the path between them.

🧠 Learning from Everything, Storing What Matters

Claude Cache revolutionizes how AI coding assistants remember. Unlike traditional tools that only save working code, we capture your complete learning journey:

✅ Success Patterns - What Works

• Elegant solutions that worked first time
• Proven approaches you can trust
• Best practices from your actual experience

🚫 Anti-Patterns - What Doesn't Work

• Failed approaches to avoid
• Dead ends that waste time
• Context-specific pitfalls you've discovered

🗺️ Journey Patterns - The Path to Solution

• Complete problem-solving sequences
• Key insights that unlock breakthroughs
• The "why" behind the solution

Why This Changes Everything

Consider this real scenario:

Monday: You spend 2 hours debugging an authentication loop
  - Try localStorage fix (fails)
  - Check cookies (fails)
  - Debug state management (fails)
  - Finally realize it's a useEffect issue (success!)

Friday: You hit the same auth loop issue

Without Claude Cache: You might try localStorage again, wasting time on approaches that didn't work.

With Claude Cache:

• ⚠️ Immediately warns: "Don't check localStorage - that failed before"
• ✅ Suggests: "This is likely a useEffect issue - here's what worked"
• 🗺️ Shows the journey: "Last time this took 4 attempts, skip to solution #4"

🎯 Pattern Classification System

Every pattern is classified by quality and type:

Type	Symbol	Description	Example
Gold	🏆	Worked first time, elegant	"useEffect with cleanup solved it immediately"
Silver	🥈	Worked after 2-3 attempts	"Third approach with useMemo worked"
Bronze	🥉	Eventually worked	"Finally solved after trying 5 approaches"
Anti-Pattern	🚫	Confirmed failure	"localStorage doesn't work for auth tokens"
Journey	🗺️	Complete problem→solution path	"Auth fix: tried A, B failed → C worked because..."
Caution	⚠️	Works but has tradeoffs	"Quick fix but needs refactoring"

🚀 Quick Start (2 Minutes)

1. Install Claude Cache

# Using pipx (recommended - isolated installation)
pipx install "claude-cache[mcp]"

# Alternative: Using pip directly
pip install --user "claude-cache[mcp]"

# Basic version
pipx install claude-cache

2. First Run - Choose Your Mode

Real-time Learning (Recommended):

cache start --watch

One-time Processing:

cache start

You'll see:

✓ Knowledge base initialized at ~/.claude/knowledge/cache.db
Processing 47 existing log files...
  Processing: YourProject/session1.jsonl
  Processing: YourApp/session2.jsonl
  ...
✓ Learned 23 patterns from your history
Starting real-time monitoring...

What's happening?

• Claude Cache found all your past Claude Code sessions
• It's analyzing your historical coding patterns
• Learning from your successes AND failures
• Building your personal knowledge base

3. Use It Immediately

# Interactive monitoring dashboard (press 'h' for help, 't' for tutorial)
cache monitor

# Query your knowledge
cache query "authentication"

# Get contextual suggestions
cache suggest

# See what you've learned
cache stats

3. Claude Code Integration (Optional)

Add to your .claude.json:

{
  "mcpServers": {
    "cache": {
      "type": "stdio",
      "command": "cache-mcp"
    }
  }
}

Start MCP server separately:

cache-mcp

Restart Claude Code and type / to see your new tools!

4. Test It's Working

# Check status
cache stats

# Search existing patterns
cache query "authentication"

# Get suggestions
cache suggest --context "working on APIs"

🔬 How It Works

Claude Cache uses dual-path learning to build comprehensive intelligence:

1. Historical Analysis (First Run)

• Processes all your existing Claude Code sessions
• Extracts patterns from past successes and failures
• Builds initial knowledge base from your history
• Takes 30 seconds to 10 minutes depending on history size

2. Real-Time Monitoring (Continuous)

• Watches your coding sessions in real-time
• Captures successful solutions ("perfect!", "works!")
• Learns from failures (errors, "broken", "failed")
• Records complete problem→solution journeys
• Zero lag - runs silently in background

3. Intelligent Retrieval

• Semantic Search: ML-powered understanding of meaning
• Pattern Matching: Finds similar problems across projects
• Context Awareness: Right solution for your specific stack
• Journey Replay: Shows the path that worked before

4. Privacy First Design

• 100% Local: All data stays on your machine
• No Cloud: Never uploads or shares your patterns
• No Telemetry: We don't track what you're learning
• You Own It: SQLite database you fully control

📊 What Gets Captured?

✅ Automatically Captured:

• Solutions that work (you say "thanks", "perfect", "works")
• Approaches that fail (errors occur, you say "broken", "failed")
• Complete problem→solution journeys
• Patterns that repeat across projects
• High-confidence solutions (80%+ success rate)
• Consistent failures (repeatedly don't work)

❌ Not Captured:

• Every single edit or keystroke
• Low-confidence patterns
• Project-specific hacks
• Trial-and-error noise
• One-off solutions

Perfect For

• Solo Developers: Build a personal knowledge base of solutions
• Development Teams: Share successful patterns and best practices
• Learning: Capture and revisit complex problem-solving approaches
• Productivity: Eliminate repetitive problem-solving across projects

💡 Real-World Impact

After using Claude Cache for a month, developers typically have:

• 50-100 high-quality patterns per project
• 30-50 anti-patterns preventing repeated mistakes
• 20-30 journey patterns showing problem-solving paths
• 90%+ relevance rate when patterns are suggested
• 50% reduction in time spent on familiar problems

Example Output

$ cache query "auth redirect"

🔍 Found 3 relevant patterns:

1. ✅ Success Pattern (React)
   "useEffect cleanup prevents auth redirect loops"
   Project: YourApp | Confidence: 92%

2. 🚫 Anti-Pattern
   "Don't store auth tokens in localStorage"
   Failed in: YourApp, AnotherApp | Alternative: Use httpOnly cookies

3. 🗺️ Journey Pattern
   "Auth loop fix: localStorage ❌ → cookies ❌ → useEffect ✅"
   Time saved next time: ~45 minutes

Performance

• Speed: <100ms query response for 10K+ patterns
• Accuracy: 60-90% relevance in semantic matching
• Storage: Efficient SQLite with optional vector embeddings
• Privacy: Zero external API calls, completely local
