## The Problem Every Developer Faces

| Without VasperaMemory | With VasperaMemory |
|----------------------|-------------------|
| "We use Supabase, not Firebase..." (every session) | AI already knows your stack |
| "No mock data, use real APIs..." (again) | Preferences remembered forever |
| "This error? I fixed it last week..." | Previous fix suggested instantly |
| "Don't change that file, it'll break auth" | Impact analysis warns you first |
| Re-explaining architecture every day | Context persists across all tools |

**Developers lose 2-3 hours daily re-explaining context to AI tools.** VasperaMemory eliminates this completely.

## ✨ Key Features

### 💰 **Token Savings Metrics**
See exactly how many tokens VasperaMemory saves by compressing your context. Uses **tiktoken** for accurate measurement.
```bash
npx vasperamemory status
# Shows: Compressed: 1.2K tokens | Full history: 8.5K | Saved: 86%
```

### 🏠 **Local-Only Mode**
Run VasperaMemory **100% offline** with local SQLite storage. No cloud, no API keys, complete privacy.
```bash
npx vasperamemory@latest connect --local
```

### 📚 **Documentation Intelligence** ⭐ NEW
Auto-index all your markdown docs with data lineage tracking. Search across specs, guides, and technical docs. Detect knowledge gaps.
```bash
# Auto-indexes docs/ folder on connect
index_documentation → get_indexed_docs → search_docs
```

### 🔗 **File Relationship Analysis** ⭐ NEW
Understand how your files are connected through imports, git co-changes, and test relationships.
```bash
analyze_file_relationships → get_related_files
```

### 🔄 **Auto-Indexing** ⭐ NEW
Automatic entity extraction when files are mentioned. No manual indexing — just use VasperaMemory normally and it builds a knowledge graph in the background.
```bash
# Entities extracted: functions, classes, imports, exports
# Import graph built automatically
# Patterns tracked with file counts
reindex_project  # Manual bulk re-index when needed
```

### 📝 **Git Decision Extraction** ⭐ NEW
Automatically extract architectural decisions from your commit messages. Keywords like "decided", "refactored", "migrated" trigger auto-capture.
```bash
extract_decisions_from_commits
```

### 🤖 **Zero-Effort Context Injection**
Context is **automatically injected** when you start a session. No tools to call — your AI already knows your project, recent decisions, and warnings.

### 🎯 **Smart Intent Router**
Just ask `help_me "Is it safe to change auth.ts?"` — VasperaMemory figures out which tools to call and returns a fused answer. No memorizing 30 tools.

### ⚠️ **Proactive Risk Warnings**
Mention a file? VasperaMemory automatically checks its risk level, known issues, and past problems — warns you before you break something.

### 🔍 **Automatic Error Recognition**
See an error in terminal output? VasperaMemory auto-detects it and suggests past fixes. No searching required.

### 🧠 **Persistent AI Memory**
Your decisions, patterns, and preferences persist across sessions and tools. Tell your AI once, it remembers forever.

### 🔄 **Cross-Tool Sync**
Works with **Cursor**, **Claude Code**, **Windsurf**, **VS Code + Copilot**, **JetBrains**, and any MCP-compatible tool. One memory, all tools.

### ⚡ **Auto-Capture from Git**
Decisions are automatically extracted from your commit messages via git hooks. Zero manual entry — every commit teaches your AI.

### 🔧 **Smart Error Memory**
When you fix an error, that fix is saved. Next time the same error appears, the fix is suggested instantly.

### 📊 **Code Intelligence**
Deep AST analysis: detect design patterns, calculate complexity, find code smells, get architectural insights.

### 🎯 **Impact Analysis**
Before changing code, see what depends on it. Catch breaking changes before they happen.

### ⏳ **Temporal Evolution** ⭐ NEW
Track how your code evolves over time. See entity timelines, detect renames, and identify stability patterns.
```bash
get_entity_evolution → detect_semantic_drift → get_evolution_patterns
```

### 🔮 **Proactive Intelligence** ⭐ NEW
AI-powered pattern detection and change impact prediction. Find similar code across your codebase.
```bash
detect_patterns → predict_change_impact → find_similar_code
```

### 🔗 **Cross-Project Learning**
Patterns that worked in your other projects are automatically suggested in new ones.

### 📋 **Session Continuity**
Every session resumes where you left off: pending work, recent decisions, warnings, and context.
