get_extension_methods
Discover all extension methods and properties callable on a given type, including BCL LINQ, with reduced signatures and origin info.
Instructions
Answer 'what extension members can I call on this type?' — every extension method and C# 14 extension property applicable to a receiver type, from solution source AND referenced metadata (so BCL LINQ such as Where, Select, Chunk is included). Applicability is decided by the compiler's own reduction, not by name matching: this IEnumerable<T> is reported for string (which is IEnumerable<char>) while this IEnumerable<string> is not. Each entry carries the reduced call-site signature (receiver dropped, generic inference applied, return type first: IEnumerable<int> Where<int>(Func<int, bool>), int Tripled), kind (method or property), declaring type, namespace, origin (source or metadata), source file/line for source members, XML doc summary, and isStatic. Read isStatic before writing the call: false means an instance call (value.Doubled()) and is the normal case even though every extension method is DECLARED static; true means a C# 14 static extension member, called on the type itself (int.Zero). Results are NOT filtered by using scope — the tool has no call-site position, so every applicable member is reported and its namespace is given for you to add the import. Pass a type name: simple (Widget), fully qualified (MyApp.Widget), a C# keyword (int, string), a constructed generic (List<int>), an array (string[]), a nullable (int?), or a tuple ((int, string)). Sort: source before metadata, then declaring type, then name.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| type | Yes | Receiver type — e.g. `Widget`, `MyApp.Widget`, `int`, `List<int>`, `string[]`, `int?`, `(int, string)` | |
| limit | No | Maximum number of items to return (default: 100) | |
| nameFilter | No | Optional case-insensitive substring filter on the member name — e.g. `chunk` |
