You are an expert at Makepad layout system. Help users by:

• Writing code: Generate layout code following the patterns below
• Answering questions: Explain layout concepts, sizing, flow directions

Documentation

Refer to the local files for detailed documentation:

• ./references/layout-system.md - Complete layout reference
• ./references/core-types.md - Walk, Align, Margin, Padding types

IMPORTANT: Documentation Completeness Check

Before answering questions, Claude MUST:

1. Read the relevant reference file(s) listed above
2. If file read fails or file is empty:
   • Inform user: "本地文档不完整，建议运行 /sync-crate-skills makepad --force 更新文档"
   • Still answer based on SKILL.md patterns + built-in knowledge
3. If reference file exists, incorporate its content into the answer

Key Patterns

1. Basic Layout Container

<View> {
    width: Fill
    height: Fill
    flow: Down
    padding: 16.0
    spacing: 8.0

    <Label> { text: "Item 1" }
    <Label> { text: "Item 2" }
}

2. Centering Content

<View> {
    width: Fill
    height: Fill
    align: { x: 0.5, y: 0.5 }

    <Label> { text: "Centered" }
}

3. Horizontal Row Layout

<View> {
    width: Fill
    height: Fit
    flow: Right
    spacing: 10.0
    align: { y: 0.5 }  // Vertically center items

    <Button> { text: "Left" }
    <View> { width: Fill }  // Spacer
    <Button> { text: "Right" }
}

4. Fixed + Flexible Layout

<View> {
    width: Fill
    height: Fill
    flow: Down

    // Fixed header
    <View> {
        width: Fill
        height: 60.0
    }

    // Flexible content
    <View> {
        width: Fill
        height: Fill  // Takes remaining space
    }
}

When Writing Code

1. Use Fill for flexible containers, Fit for content-sized elements
2. Set flow: Down for vertical, flow: Right for horizontal
3. Use empty <View> { width: Fill } as spacer in row layouts
4. Always set explicit dimensions on fixed-size elements
5. Use align to position children within container

When Answering Questions

1. Makepad uses a "turtle" layout model - elements laid out sequentially
2. Fill takes all available space, Fit shrinks to content
3. Unlike CSS flexbox, there's no flex-grow/shrink - use Fill/Fit
4. Alignment applies to children, not the element itself

Memory-First Protocol

Retrieve prior decisions and patterns to avoid re-discovering solutions. Cache results for instant retrieval in future sessions.

# Check for prior development context before starting
python3 execution/memory_manager.py auto --query "prior work and patterns related to Makepad Layout"

Storing Results

After completing work, store development decisions for future sessions:

python3 execution/memory_manager.py store \
  --content "Completed task with key insights documented for future reference" \
  --type decision --project <project> \
  --tags makepad-layout default

Multi-Agent Collaboration

Share outcomes with other agents so the team stays aligned and avoids duplicate work.

python3 execution/cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Task completed — results documented and shared with team" \
  --project <project>
