+# CLAUDE.md - Guidelines for Fossa CLI
+
+## Build Commands
+- Haskell: `cabal build`, `make build-cli`
+- Rust: `cargo build --release`
+- Full Build: `make build` (builds both)
+- Unit Tests (Haskell): `cabal test unit-tests` or `make test-cabal ARGS="TestName"`
+- Unit Tests (Rust): `cargo test` or `make test-cargo`
+- Integration Tests: `make integration-test ARGS="TestName"`
+- Format Code: `make fmt` (runs both formatters)
+- Lint Code: `make lint` (runs both linters)
+- Analyze Project: `make analyze`
+
+## Code Quality Standards
+- Compiler warnings should be treated as errors and fixed, not ignored
+- Linter warnings should be treated as errors and fixed, not ignored
+- All tests must pass before submitting code
+- Code should be thoroughly tested with appropriate unit tests
+
+## Code Style Guidelines - Haskell
+- GHC Version: 9.8
+- Formatting: `fourmolu` with 2 spaces, leading commas
+- Imports: Use explicit imports, qualified with full names
+- Types: Prefer `newtype`, use `Text` instead of `String`
+- Functions: Avoid partial functions, list comprehensions, match guards
+- Error handling: Never use `error` or `undefined`
+
+## Code Style Guidelines - Rust
+- Format with `rustfmt` via `cargo fmt`
+- Lint with Clippy via `cargo clippy`
+- Follow standard Rust idioms including error handling
+- Use the Rust embedded tools within the Haskell code via the extlib directory
