# Claude Instructions

## Project Overview
DataBuild is a bazel-based data build system. Key files:
- [`databuild.proto`](databuild/databuild.proto) - System interfaces
- [`manifesto.md`](manifesto.md) - Project philosophy
- [`core-concepts.md`](core-concepts.md) - Core concepts

## Build & Test
```bash
# Run all tests
./scripts/bb_test_all

# Remote testing
./scripts/bb_remote_test_all

# Do not try to `bazel test //examples/basic_graph/...`, as this will not work.
```

## Project Structure
- `databuild/` - Core system (Rust/Proto)
- `examples/` - Example implementations
- `scripts/` - Build utilities

## Key Components
- Graph analysis/execution in Rust
- Bazel rules for job orchestration
- Java/Python examples for different use cases
