7. Utils

This section documents the command-line tools that ship with daslang — every tool under the SDK’s utils/ has a page here, from the test framework and lint runner to the AI-assistant servers and the dasLLAMA inference stack — plus the runtime profiler and a cheat sheet for every built-in leak-detection mechanism.
