name	simulink-interactions
description	Resolve references to the currently open or selected Simulink context ("this model", "this subsystem", "this block", "selected blocks") and find blocks in an open model. Use whenever the user refers to "this model", "this block", "this subsystem", "selected blocks", or asks to find specific blocks in an already-open model. After resolving context, hand off to the appropriate Simulink skill for edits, simulation, or testing.

Simulink Open Model Context Resolution

Resolve what the user is referring to in an already-open Simulink session, then route to the right skill.

When to Use

• User says "this model", "this block", "this subsystem", "selected blocks"
• User asks to find or locate blocks in the currently open model
• User refers to a model without specifying a file path to open

When NOT to Use

• Adding, connecting, deleting, or configuring blocks → use building-simulink-models
• Running simulations, parameter sweeps, accessing logsout → use simulating-simulink-models
• Writing pass/fail behavioral tests → use testing-simulink-models
• Organizing variables and data dictionaries → use simulink-data-management

Step 1: Resolve the Target

Use mcp__simulink__evaluate_matlab_code to resolve references:

User says	MATLAB expression
"this model"	bdroot(gcs)
"this system" / "this subsystem"	gcs
"this block"	gcb
"selected blocks" (plural)	see snippet below
"all [Type] blocks in this subsystem"	see snippet below
"all [Type] blocks in the model"	see snippet below

Always verify the result is non-empty. If gcb or gcs returns an empty string, tell the user no block or subsystem is currently selected and ask them to select one or provide a path.

Selected blocks (plural)

opts = Simulink.FindOptions;
opts.SearchDepth = 1;
blks = getfullname(Simulink.findBlocks(gcs, 'Selected', 'on', opts));
if isempty(blks)
    disp('No blocks are currently selected.');
else
    disp(blks)
end

All blocks of a specific type in the current subsystem

opts = Simulink.FindOptions;
opts.SearchDepth = 1;
BlockType = 'Gain'; % replace with actual type
blks = getfullname(Simulink.findBlocksOfType(gcs, BlockType, opts));

All blocks of a specific type in the entire model

BlockType = 'Gain'; % replace with actual type
blks = getfullname(Simulink.findBlocksOfType(bdroot, BlockType));

Step 2: Hand Off

Once you have the resolved block path(s) or model name, use it as input to the appropriate skill:

User intent	Hand off to
Inspect model structure or topology	model_read / model_overview
Query parameter values	model_query_params
Resolve variable-backed values	model_resolve_params
Edit structure or parameters	building-simulink-models (via model_edit)
Run simulation or access results	simulating-simulink-models
Write or run pass/fail tests	testing-simulink-models
Organize variables or dictionaries	simulink-data-management
