7. Utils

This section documents the command-line tools that ship with daslang: the live-reload application host, the test framework, the code coverage tool, the lint checker, the package manager, the MCP server for AI coding assistants, the LSP server for editors and AI diagnostics, the cross-file duplicate-function detector and its AI judge, the runtime profiler and memory-leak tracker, the OpenAI-compatible dasLLAMA inference server, and a cheat sheet for every built-in leak-detection mechanism.
