Supporting files include documentation, CMake presets, GitHub Actions workflows, editor settings, repository metadata, and AI-agent guidance. ## Workflow 1. Check the current repository facts before editing docs: CMake version, preset names, build directories, executable paths, and test target names. 2. Keep support changes consistent across `README.md`, `.github/CONTRIBUTING.md`, `docs/`, `.github/copilot-instructions.md`, and `AGENTS.md`. 3. Prefer CMake presets in documented commands. 4. Keep CI aligned with local presets. 5. Do not modify engine source files unless a supporting workflow is broken because of source layout changes. ## Validation For docs-only changes, validate command accuracy with lightweight checks where practical: ```bash cmake --list-presets ctest --test-dir build-dev -N ``` For CMake preset or CI command changes: ```bash cmake --preset dev cmake --build --preset dev ctest --preset dev ``` ## Documentation standards - Lead with quick-start commands. - Use tables for command and directory references. - Avoid stale exact test counts unless they are generated automatically. - Document `PERFT_MAX_DEPTH=4` for quick perft runs. --- > Source: [sneivandt/chess](https://github.com/sneivandt/chess) — distributed by [TomeVault](https://tomevault.io).
