kyrie66nb 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→ usesimulating-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 |
