+# AGENTS.md
+
+This file provides instructions for agentic coding assistants working in this Rust repository.
+
+## Build and Test Commands
+
+```bash
+# Build project (debug)
+make build
+
+# Build release version
+make release
+
+# Run application
+make run
+
+# Run all tests
+make test
+
+# Run a specific test
+cargo test --test <test_module_name>
+
+# Clean build artifacts
+make clean
+```
+
+## Linting and Formatting
+
+```bash
+# Run linter (Clippy)
+make lint
+
+# Auto-format code (Rustfmt)
+make format
+
+# Auto-fix lint issues
+make fix
+```
+
+## Cross-Compilation Targets
+
+The project supports cross-compilation using `cross`. Available targets:
+
+```bash
+make linux-musl         # x86_64 Linux (musl)
+make aarch64-linux-musl # ARM64 Linux (musl)
+make aarch64-android    # ARM64 Android
+make linux-gnu          # x86_64 Linux (GNU)
+make windows-gnu        # x86_64 Windows
+make freebsd            # x86_64 FreeBSD
+make loongarch          # LoongArch Linux
+```
+
+## Code Style Guidelines
+
+### General
+- **File encoding**: UTF-8
+- **Line endings**: LF (Unix-style)
+- **Trailing whitespace**: Must be trimmed
+- **Final newline**: Required at end of file
+
+### Rust-specific
+- **Indentation**: 4 spaces (no tabs)
+- **Import style**: Grouped as shown in Cargo.toml:
+  1. Standard library
+  2. External dependencies
+  3. Internal modules
+- **Naming conventions**:
+  - Variables/functions: `snake_case`
+  - Types: `PascalCase`
+  - Constants: `SCREAMING_SNAKE_CASE`
+- **Error handling**:
+  - Use `anyhow` for application errors
+  - Use `thiserror` for structured error types
+  - Prefer `?` operator over `unwrap()`
+  - Avoid `panic!` in production code
+- **Type annotations**:
+  - Use Rust's type inference where possible
+  - Explicitly annotate public API signatures
+  - Use `derive` macros for common traits (Debug, Clone, etc.)
+
+### Documentation
+- **Public API**: Must have doc comments `///`
+- **Module-level**: Use `//!` at top of module files
+- **Examples**: Include usage examples in doc comments
+
+## Development Workflow
+
+```bash
+# Watch mode with live reload
+make dev
+
+# Check for compilation errors
+make check
+```
+
+## Configuration
+
+- Project configuration uses TOML format (`config.example.toml`)
+- Copy `config.example.toml` to `config.toml` and customize
+
+## Performance Optimization
+
+Release builds include these optimizations:
+```toml
+[profile.release]
+opt-level = 3
+strip = true
+lto = true
+panic = "abort"
+codegen-units = 1
+```
+
+## Dependencies Management
+
+- Dependencies are managed via Cargo.toml
+- Always run `cargo update` after modifying dependencies
+- Use exact version pins (">=0.1.0") for production dependencies
+
+## Git Integration
+
+- Branch naming: `<type>/<short-description>`
+- Commit messages:
+  - Use imperative mood ("Add feature" not "Added feature")
+  - First line <= 50 characters
+  - Body explains "why" not just "what"
+```
