# 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)

```matlab
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

```matlab
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

```matlab
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` |
