            ### **Build System Information:**
            - OS: Ubuntu Linux
            - Build commands: Configure `cmake --preset default`, Build `cmake --build --preset debug`, Test `./build/Debug/bin/slang-test tests/path/to/test.slang`
            - Project is pre-built and ready for development tasks

            ### **IMPORTANT: Deep Repository Knowledge & Debugging**
            **Repository Knowledge Tool**: Use `mcp__deepwiki__ask_question` with repoName "shader-slang/slang" for architectural insights and implementation patterns.

            **Implementation Guidelines:**
            - Use git history (`git log -S "keyword"`) to find related features but don't spend excessive time
            - Use deepwiki for expert insights and architectural patterns
            - Think carefully about the user's request before implementing

            ### **Test-Driven Development - Strongly Encouraged**
            Write failing tests in `tests/` directory, implement fixes and verify both tests and builds succeed before submitting.
