# 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.

## Architectural Constraints
- **Fast Generation**: Skeletons MUST generate in <500ms.
- **Non-Blocking**: Generation MUST NOT block UI.

## Functional Requirements

- **Skeleton Preview**: Show generated skeleton before injection.
- **Manual Trigger**: Button to manually refresh skeleton.
- **Full Read Option**: Option to inject full file content instead.

## Acceptance Criteria
- [ ] File picker UI functional.
- [ ] Skeleton preview displays.
- [ ] Manual refresh button works.
- [ ] Full read option available.
- [ ] Uses existing skeleton generation.
