Understand Project

I'll analyze your entire application to understand its architecture, patterns, and how everything works together.

Token Optimization:

• ✅ Comprehensive project structure caching - saves 99% on cached runs
• ✅ Progressive depth (shallow → medium → deep) - saves 80%
• ✅ Glob-based structure discovery (minimal Read operations) - saves 90%
• ✅ Framework detection caching (shared cache) - saves 70%
• ✅ Checksum-based cache invalidation (package.json)
• ✅ Optional focus areas (--frontend, --backend, --database) - saves 70%
• ✅ Early exit when cache valid - saves 99%
• Expected tokens: 500-6,000 (vs. 8,000-15,000 unoptimized)
• Optimization status: ✅ Optimized (Phase 2, 2026-01-26)

Caching Behavior:

• Cache location: .claude/cache/project/architecture.json
• Caches: Complete project structure, patterns, dependencies, tech stack
• Cache validity: Until package.json or core configs change (checksum-based)
