# Track Specification: Manual Skeleton Context Injection (manual_skeleton_injection_20260306)

## 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.

## 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 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` |

## Acceptance Criteria
- [ ] File picker UI functional
- [ ] Skeleton preview displays
- [ ] Manual refresh button works
- [ ] Full read option available
- [ ] 1-space indentation
