S32ct Quadspi Facade

name: s32ct-quadspi-facade
description: >
  Headless facade that fronts the QuadSPI tool of NXP S32 Configuration
  Tools via `nxp_s32ct_execute_action(action_name="s32ct.configure_quadspi", params={...})`. Triggers when
  users ask to import a binary QuadSPI image via `-ImportBin` and export
  QuadSPI artifacts as binary, C source, or MEX from a `.mex` project. Also
  handles bootstrapping QuadSPI from `-EmptyConfig` with `mcu` +
  `sdk_version`. Delegates shared launcher plumbing (workspace `-data`,
  `s32ct_launcher`, `launcher_ini`, `timeout_s`,
  retry-on-`IllegalStateException`) to the generic `s32ct-cli` skill.

# S32CT QuadSPI - Headless Facade

Thin per-tool facade over the generic `s32ct-cli` skill that exposes only the
flags relevant to the **QuadSPI** tool of S32 Configuration Tools. This skill
fronts the `nxp_s32ct_execute_action` MCP tool with `action_name="s32ct.configure_quadspi"` (the
`tool_name` is pre-filled from the action). All shared launcher plumbing,
validation, and auto-retry behavior is inherited from `s32ct-cli`.

## When to use

Use this skill when:
- You need to import a binary QuadSPI image into a `.mex` via `-ImportBin`.
- You need to export QuadSPI artifacts: binary, C source, or MEX.
- You need to bootstrap QuadSPI from `-EmptyConfig` (requires `mcu` +
  `sdk_version`).

**Migration note:** The standalone `quadspi` MCP tool no longer exists - it
has been replaced by the unified `nxp_s32ct_execute_action` dispatcher's
`quadspi` action. Existing inputs are unchanged.

Do **not** use this skill for:
- Cross-tool operations combining flags from multiple tools -> use
  `s32ct-cli` (s32ct.configure_cli).
- IVT / DCD binary handling - use the matching facade.

## Available Capabilities

| Type | Name | Invocation |
|------|------|------------|
| MCP tool | `nxp_s32ct_execute_action` | `nxp_s32ct_execute_action(action_name="s32ct.configure_quadspi", params={...})` |
| Resource | `skill://nxp_s32ct/s32ct-quadspi-facade` | Auto-loaded on trigger |

## Quickstart

### 1. Load or bootstrap a `.mex`

```
Tool:    nxp_s32ct_execute_action
Action:  s32ct.configure_quadspi
Input:   project_path="<path>.mex"   # OR empty_config=True + mcu + sdk_version
Output:  {exit_code, command, stdout_tail, stderr_tail, values, summary}
```

### 2. Apply QuadSPI-specific modifications and export

```python
nxp_s32ct_execute_action(
    action_name="s32ct.configure_quadspi",
    params={
        "project_path": "<path>.mex",
        "import_bin": "<qspi>.bin",       # -ImportBin
        "export_kind": "ExportBin",       # or ExportAll|ExportC|ExportMEX
        "output_dir": "<output-dir>",
    },
)
```

### 3. Verify the export

Check that `output_dir` contains the expected artifacts and `exit_code == 0`.

## Inputs

### Mode (mutually exclusive)
- `project_path` - existing `.mex` to load via `-Load`.
- `empty_config` - if `True`, `-EmptyConfig`; requires `mcu` + `sdk_version`.
- `config_name` - `-ConfigName <...>`.

### Tool-specific
- `import_bin` - `-ImportBin <path>`.

### Export
- `export_kind` in {`ExportAll, ExportBin, ExportC, ExportMEX`}.
- `output_dir` - required when `export_kind` is set.

### Launcher / plumbing (shared with `s32ct-cli`)
- `data_dir` (`-data <workspace>`), `extra_args`, `s32ct_launcher`,
  `launcher_ini`, `timeout_s` (default 600).

## Output

Same as `s32ct-cli`:
`{ exit_code, command, stdout_tail, stderr_tail, values, summary }`.

## Guardrails

**Scope**
- Only drives the **quadspi** action of `nxp_s32ct_execute_action`. For
  cross-tool workflows use `s32ct-cli` (s32ct.configure_cli) instead.
- Does not modify hardware or program devices.

**Destructive actions**
- Exports overwrite files in `output_dir`. Confirm the target directory
  is safe or empty before invoking with `export_kind` set.

**Refuse-and-escalate**
- Missing `project_path` AND missing `empty_config`/`mcu`/`sdk_version`
  combination -> ask which mode.
- Unknown `export_kind` value -> list allowed values.
- Retryable `IllegalStateException` -> auto-retry once, then escalate.

## Validation loop

1. `exit_code == 0`.
2. `output_dir` contains the expected artifacts for the chosen `export_kind`.

## Out of scope

- Interactive GUI operations - use S32 Configuration Tools directly.
- Cross-tool operations combining multiple tools' flags - use `s32ct-cli`.
- Distribution portability handled transparently; see
  `s32ct-distributions`.
