+# What Context Do You Need?
+
+Before answering my question, tell me what files you need to see.
+
+## My Question
+
+{{question}}
+
+## Instructions
+
+1. Based on my question, list the files you would need to examine
+2. Explain why each file is relevant
+3. Note any files you've already seen in this conversation
+4. Identify what you're uncertain about
+
+## Output Format
+
+```markdown
+## Files I Need
+
+### Must See (required for accurate answer)
+- `path/to/file.ts` — [why needed]
+
+### Should See (helpful for complete answer)
+- `path/to/file.ts` — [why helpful]
+
+### Already Have
+- `path/to/file.ts` — [from earlier in conversation]
+
+### Uncertainties
+- [What I'm not sure about without seeing the code]
+```
+
+After I provide these files, I'll ask my question again.
