 ## Overview
 Add UI controls to manually flag files for skeleton injection in discussions. Allow agent to request full file reads or specific def/class definitions on-demand.
 
-## Architectural Constraints
-- **Fast Generation**: Skeletons MUST generate in <500ms.
-- **Non-Blocking**: Generation MUST NOT block UI.
+## Current State Audit
+
+### Already Implemented (DO NOT re-implement)
+- **`file_cache.ASTParser.get_skeleton()`**: Returns Python skeleton
+- **`mcp_client.py_get_skeleton()`**: MCP tool for skeleton generation
+- **`aggregate.py`**: Builds file items context
+
+### Gaps to Fill
+- No UI to flag files for skeleton vs full
+- No preview of skeleton before injection
+- No on-demand definition lookup
 
 ## Functional Requirements
-- **File Picker**: Browse and select files for skeleton injection.
-- **Skeleton Preview**: Show generated skeleton before injection.
-- **Manual Trigger**: Button to manually refresh skeleton.
-- **Full Read Option**: Option to inject full file content instead.
+- File picker UI in discussion panel
+- Skeleton preview before injection
+- Toggle: skeleton vs full file
+- Uses existing `py_get_skeleton()` tool

+## Key Integration Points
+| File | Purpose |
+|-----|---------|
+| `src/gui_2.py` | File picker, injection UI |
+| `src/mcp_client.py` | `py_get_skeleton()` |
+| `src/file_cache.py` | `ASTParser` |
