description	Toggle KLayout layer visibility on and off for better visualization. Use this skill when the user wants to show/hide layers, toggle layer display, change layer visibility, or focus on specific layers in KLayout. Also trigger when the user says things like "hide the metal layer", "show only mesa", "turn off layer 3", or wants to isolate layers for inspection.

KLayout Display Skills

Toggle layer visibility in KLayout via the MCP server for better visualization during design review.

Prerequisites

• KLayout running with KlayoutClaw plugin (v0.3+)
• A layout with layers must be open

Script

toggle_layer.py — Toggle layer visibility

python scripts/toggle_layer.py <layer> <datatype> [on|off]

• on — make layer visible
• off — make layer invisible
• Omit to toggle current state

Examples:

python scripts/toggle_layer.py 1 0 off    # hide mesa layer
python scripts/toggle_layer.py 2 0 on     # show metal layer
python scripts/toggle_layer.py 3 0        # toggle bonding pads

show_only.py — Show only specified layers, hide all others

python scripts/show_only.py <layer1/dt1> [<layer2/dt2> ...]

Example:

python scripts/show_only.py 1/0 2/0      # show only mesa + metal, hide pads

How It Works

The scripts use execute_script to manipulate pya.LayerProperties in the current LayoutView. Each layer properties entry has a visible attribute that controls display.

For custom display manipulation beyond these scripts, use execute_script directly:

tool_call("execute_script", code="""
lp_iter = _layout_view.begin_layers()
while not lp_iter.at_end():
    lp = lp_iter.current()
    lp.visible = (lp.source_layer == 1)  # show only layer 1
    _layout_view.set_layer_properties(lp_iter, lp)
    lp_iter.next()
""")
