+
+## Description
+
+Execute arbitrary C# code inside the Unity Editor. The code runs as a method body with access to UnityEngine and UnityEditor namespaces. Use 'return' to send data back. Compiled in-memory — no script files created. Actions: execute (run code), get_history (list past executions), replay (re-run a history entry), clear_history. NOTE: safety_checks blocks known dangerous patterns but is not a full sandbox. Compiler options: 'auto' (Roslyn if available, else CodeDom), 'roslyn' (C# 12+, requires Microsoft.CodeAnalysis), 'codedom' (C# 6 only).
+
+## Parameters
+
+| Name | Type | Required | Description |
+|------|------|----------|-------------|
+| `action` | `Literal['execute', 'get_history', 'replay', 'clear_history']` | yes | Action to perform. |
+| `code` | `str \| None` | — | C# code to execute (for 'execute' action). Must be a valid method body. Access UnityEngine and UnityEditor namespaces. Use 'return' to send data back. |
+| `safety_checks` | `bool` | — | Enable basic blocked-pattern checks (File.Delete, Process.Start, infinite loops, etc). Not a full sandbox — advanced bypass is possible. Default: true. |
+| `index` | `int \| None` | — | History entry index to replay (for 'replay' action). |
+| `limit` | `int` | — | Number of history entries to return (for 'get_history' action, 1-50). Default: 10. |
+| `compiler` | `Literal['auto', 'roslyn', 'codedom']` | — | Compiler backend for 'execute' action. 'auto' uses Roslyn if Microsoft.CodeAnalysis is installed, else falls back to CodeDom. 'roslyn' forces Roslyn (C# 12+). 'codedom' forces legacy CSharpCodeProvider (C# 6). Default: auto. |
+
+## Returns
+
+A `dict` containing the Unity response. The exact shape depends on the action.

+## Examples

+## Description
+
+Creates and modifies ScriptableObject assets using Unity SerializedObject property paths.
+
+## Parameters
+
+| Name | Type | Required | Description |
+|------|------|----------|-------------|
+| `action` | `Literal['create', 'modify']` | yes | Action to perform: create or modify. |
+| `type_name` | `str \| None` | — | Namespace-qualified ScriptableObject type name (for create). |
+| `folder_path` | `str \| None` | — | Target folder under Assets/... (for create). |
+| `asset_name` | `str \| None` | — | Asset file name without extension (for create). |
+| `overwrite` | `bool \| str \| None` | — | If true, overwrite existing asset at same path (for create). |
+| `target` | `dict[str, Any] \| str \| None` | — | Target asset reference {guid\|path} (for modify). |
+| `patches` | `list[dict[str, Any]] \| str \| None` | — | Patch list (or JSON string) to apply. For object references: use {"ref": {"guid": "..."}} or {"value": {"guid": "..."}}. For Sprite sub-assets: include "spriteName" in the ref/value object. Single-sprite textures auto-resolve from guid/path alone. |
+| `dry_run` | `bool \| str \| None` | — | If true, validate patches without applying (modify only). |
+
