+3. Build the workspace: `cargo build --workspace`
+4. Run tests: `cargo test --workspace`
+
+## Code Style
+
+Before submitting changes:
+
+```bash
+# Format code (requires nightly toolchain)
+cargo +nightly fmt --all
+

+# Run tests
+cargo test --workspace
+```
+
+## Commit Messages
+
+Follow the `[scope] message` convention:
+
+- `[add]` — New feature or file
+- `[fix]` — Bug fix
+- `[refactor]` — Code restructuring without behavior change
+- `[docs]` — Documentation changes
+- `[test]` — Test additions or modifications
+- `[build]` — Build system or CI changes
+
+Examples:
+
+```
+[add] input action mapping system to lambda-rs.
+[fix] mouse press events missing cursor coordinates.
+[docs] add uniform buffer tutorial.
+[refactor] extract render command encoding to separate module.
+```
+
+## Pull Requests
+
+1. Create a branch from `main` with a descriptive name.
+2. Make focused, narrowly scoped commits.
+3. Ensure all commits build independently.
+4. Fill out the PR template completely.
+5. Link related issues using "Closes #123" or "Relates to #456".
+6. Include screenshots or recordings for visual changes.
+7. List manual verification steps if automated testing is insufficient.
+
+## Issues
+
+Use the appropriate issue template:
+
+- **Feature Request**: Propose new functionality or enhancements.
+- **Bug Report**: Report incorrect behavior or defects.
+- **Documentation**: Report missing or unclear documentation.
+
+Provide sufficient detail for maintainers to evaluate and reproduce issues.
+
+## Documentation
+
+When adding or modifying features:
+
+- Update rustdoc comments for public APIs.
+- Add or update examples in `crates/lambda-rs/examples/`.
+- Create or update specifications in `docs/specs/` for significant changes.
+- Follow the documentation tone and style guidelines in `AGENTS.md`.
