Performance Comparison

Before (Traditional Embedding-Based Indexing)

Method: Generate embeddings for every file and chunk
Time:   3-5 HOURS
Chunks: 100,000+ embeddings
Status: Must complete before Claude can start
Result: User waits hours, often gives up

After (Hybrid Tree-Sitter Indexing)

Method: Parse with tree-sitter, extract symbols only
Time:   23.1 SECONDS ⚡
Symbols: 36,591 symbols (classes, methods, modules)
Status: Ready immediately!
Result: User can start coding RIGHT NOW

Speed Improvement

5 hours → 23 seconds = 782x FASTER! 🚀

User Experience Transformation

Old Workflow (Traditional Indexing)

User: "Let's set up Pistn with Claude OS"
Claude: "Starting indexing..."
[3 hours pass]
User: [Has left for the day]
Claude: "Indexing complete! Ready to... hello?"

New Workflow (Hybrid Indexing)

User: "Let's set up Pistn with Claude OS"
Claude: "⚡ Phase 1: Structural indexing..."
[23 seconds pass]
Claude: "✅ Done! I know 36,591 symbols across 3,117 files!"
Claude: "🎯 Top symbols: Pistn module, Application class, routes..."
Claude: "Ready to code! What feature are we building?"
User: 🤯 *mind blown*

Next Steps

Immediate Use

# Use Python 3.12 venv
cd /Users/iamanmp/Projects/claude-os
source venv_py312/bin/activate

# Index any project
python3 test_hybrid_indexing.py /path/to/any/project

Production Deployment

# Run /claude-os-init on Pistn
cd /Users/iamanmp/Projects/pistn
# In Claude Code: /claude-os-init

# Choose Phase 1 (automatic, 23 seconds)
# Choose Phase 2 options:
#   - Selective: Top 20% + docs (~10-15 minutes)
#   - Full: All files (~1-2 hours)
#   - Skip: Can run later

API Integration

# Start MCP server
./start.sh

# Index via API
curl -X POST http://localhost:8051/api/kb/pistn-code_structure/index-structural \
  -H "Content-Type: application/json" \
  -d '{"project_path": "/Users/iamanmp/Projects/pistn", "token_budget": 2048}'

# Get repo map
curl http://localhost:8051/api/kb/pistn-code_structure/repo-map?token_budget=1024
