Run and interact with the BartonCore reference application. Use when the user wants to start the reference app, commission devices, execute/read/write resources, or troubleshoot runtime issues. Covers CLI flags, interactive commands, isolated session management, and known pitfalls.
Format C/C++ code in BartonCore. Use when the user wants to format source files, understand formatting conventions, or fix formatting issues. Covers clang-format usage, the diff-only rule, manual blank-line conventions that clang-format cannot enforce, and the pre-commit hook.
Build BartonCore from source. Use when the user wants to compile the project, rebuild after code changes, reconfigure CMake options, or understand the build system. Covers the build.sh convenience script, incremental cmake builds, CMake configuration flags, and the development build profile.
Debug BartonCore applications and tests. Use when the user needs to set breakpoints, step through code, inspect state, or diagnose crashes. Covers three workflows — gdb for the C/C++ reference app and unit tests, pdb/debugpy for Python integration tests, and gdb-with-Python for debugging C code called from Python tests.
Work with Matter test devices in BartonCore. Use when the user wants to start Matter sample apps, use chip-tool to commission or control devices, work with matter.js virtual devices for integration testing, or create new custom virtual device types. Covers pre-built sample apps, chip-tool commands, and the matter.js sideband API.
Run BartonCore Python integration tests. Use when the user wants to run integration tests, verify end-to-end behavior, run specific test files, or filter tests by keyword or marker. Covers pytest via the py_test.sh wrapper, ASAN preloading, test filtering, prerequisites, and the CI all-in-one script.

SBMD v4 drivers are .sbmd.js JavaScript files that register a driver via SbmdDriver({...}). Validation ensures the registration object conforms to the JSON schema.
When BCORE_MATTER_VALIDATE_SCHEMAS=ON (the default), SBMD validation runs automatically as part of the build:
cmake --build build
The validate_sbmd_specs target uses Node.js to extract each driver's registration object and validates it against the JSON schema. This is the easiest way to validate.
python3 scripts/ci/validate_sbmd_v4_specs.py \
core/deviceDrivers/matter/sbmd/schema \
core/deviceDrivers/matter/sbmd/specs/*.sbmd.js
This:
.sbmd.js file in a sandboxSbmdDriver() registration object as JSON (functions → true)sbmd-spec-schema-v4.0.jsonThe validator evaluates each .sbmd.js file, extracts the SbmdDriver() registration object, and validates it against the JSON schema.
