+Based on real-world experience, these are the recommended tools:
+
+### Core Dependencies
+- **Rust Edition**: 2024 (always latest)
+- **Error Handling**: `thiserror` for libraries, `anyhow` for binaries
+- **Async Runtime**: `tokio` with full features
+- **Serialization**: `serde` with `camelCase` for JSON APIs
+
+### Web Development Stack
+- **Web Framework**: `axum` 0.8+
+- **API Documentation**: `utoipa` + `utoipa-swagger-ui`
+- **HTTP Client**: `reqwest`
+- **Database**: `sqlx` (never `rusqlite` or `tokio-postgres`)
+
+### Concurrency & Data Structures
+- **Sync Primitives**: `tokio::sync` (never `std::sync` in async)
+- **Concurrent Collections**: `dashmap` (never `Mutex<HashMap>`)
+- **Channels**: `tokio::sync::{mpsc, broadcast, oneshot}`
+
+### Configuration & Templates
+- **Config Format**: YAML (never TOML for complex configs)
+- **Config Loading**: `serde_yaml`
+- **Templates**: `minijinja` (never `handlebars`)
+- **Data Extraction**: `jsonpath-rust`
+
+### Observability
+- **Logging**: `tracing` + `tracing-subscriber` (never `env_logger`)
+- **Structured Logging**: Always use `#[instrument]` and context
+- **Log Rotation**: `tracing-appender` for production

+Every code change must pass this sequence:
+
+```bash
+# 1. Build verification
+cargo build
+
+# 2. Test execution
+cargo test
+
+# 3. Linting verification
+cargo clippy
+
