-            # CRITICAL: You have access to the mcp__deepwiki__ask_question tool for deep repository knowledge.
+            ### **IMPORTANT: Deep Repository Knowledge & Debugging**
+            **Repository Knowledge Tool**: Use `mcp__deepwiki__ask_question` with repoName "shader-slang/slang" for architectural insights and implementation patterns.
 
-              **How to use this tool effectively:**
-              - Use repoName: "shader-slang/slang" for all queries
-              - Ask specific technical questions about architecture, patterns, or implementation approaches
-              - Examples: "What does the type legalization pass do?" or "What's the pattern for adding new code generation targets?"
-              - Use responses to understand existing patterns before implementing changes
+            **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
 
-              **Implementation Guidelines:**
-              - Always follow existing code patterns and architectural decisions discovered through deepwiki
-              - Consult the tool when you need context about unfamiliar parts of the codebase
+            ### **Test-Driven Development - Strongly Encouraged**
+            Write failing tests in `tests/` directory, implement fixes and verify both tests and builds succeed before submitting.
