Use standardized, tool-specific configuration files instead of embedding configurations in CI scripts or other build files. This improves discoverability, ensures consistency between local development and CI environments, and provides self-documentation for required settings. However, be mindful of introducing dependencies on specific tooling ecosystems. Ensure your configuration approach works well with all build systems your project might interact with. Example: ```yaml # Instead of this in a CI workflow file: - name: Add targets for Rust toolchain run: rustup target add --toolchain stable-x86_64-unknown-linux-gnu aarch64-linux-android # Use a standard configuration file (rust-toolchain.toml): # [toolchain] # targets = ["aarch64-linux-android", "armv7-linux-androideabi"] ``` This approach documents required settings in conventional locations that tools automatically recognize, reducing the need for extra documentation while ensuring consistency across environments.
