-Requests detailed syntax information for a specific language kind.
+Requests the in-memory keyword definitions for a specific language. These definitions are the deserialized, viewer-processed form of the syntax data for the current region.

+  kind: string; // The language whose definitions to retrieve

+- Unknown `kind` value: `success: false`, `error: "Unknown syntax category requested"`
+
+### Language Syntax Cache List
+
+**JSON-RPC Method:** `language.syntax.cache` (call from extension to viewer)
+
+Requests the list of file names currently held in the `LLSyntaxDefCache`. This provides the extension with the available syntax definition file names that can subsequently be retrieved with `language.syntax.get`. This method takes no parameters.
+
+**Response:**
+
+```typescript

+| -------------------------------- | ---------------------------------------------------- |
+| `builtins.txt`                   | LSL built-in keyword list in plain text format |
+| `lsl_definitions.yaml`           | LSL language definitions in YAML format |
+| `lsl_keywords.xml`               | LSL keyword definitions in LLSD XML format |
+| `lsl_keywords_pretty.xml`        | LSL keyword definitions in formatted LLSD XML format |
+| `slua_default.d.luau`            | Luau type definition file for editor tooling |
+| `slua_default.docs.json`         | Luau documentation data in JSON format |
+| `slua_definitions.yaml`          | Luau language definitions in YAML format |
+| `slua_keywords.xml`              | Luau keyword definitions in LLSD XML format |
+| `slua_keywords_pretty.xml`       | Luau keyword definitions in formatted LLSD XML format |
+| `slua_selene.yml`                | Luau Selene linter configuration in YAML format |
+
+Not all files may be present in every cache — the actual list returned by `language.syntax.cache` reflects only what is available on the viewer's local filesystem at the time of the request.
+
+### Language Syntax Cache Get
+
+**JSON-RPC Method:** `language.syntax.get` (call from extension to viewer)
+
+Requests the content of a specific file from the syntax definition cache. The file name must be one of the names returned by a prior `language.syntax.cache` call. Content is returned either as a raw text string or as a parsed JSON/LLSD object depending on the `as_json` parameter.
+
+**Parameters:**
+
+```typescript
+{
+  filename: string;   // The file name to retrieve, as returned by language.syntax.cache
+  as_json?: boolean;  // Optional. If true, content is returned as a parsed object rather than raw text
+}
+```
+
+**Fields:**
+
+- `filename`: The file name to retrieve (e.g. `"lsl_keywords.xml"`, `"slua_definitions.yaml"`)
+- `as_json` (optional): When `true`, the file is deserialized and returned as a structured object in `content`. When omitted or `false`, `content` is the raw text of the file.
+
+**Response:**
+
+```typescript
+interface SyntaxCacheFile {
+  content?: string | object;  // Present only on success. String if as_json is false/omitted, object if as_json is true
+  success: boolean;
+  error?: string;             // Present only on failure
 }
 ```
 
 **Response Fields:**

+### ScriptList
+
+**JSON-RPC Method:** `script.list` (call from extension to viewer)
+
+Requests the list of all scripts currently open and tracked by the viewer, along with the viewer's temp directory. This is intended for use by a file watcher tool that needs to discover which script temp files are active without going through the full `script.subscribe` flow. This method takes no parameters.

+**Response:**

+**Response Fields:**
+
+- `temp_dir`: The absolute path to the viewer's temp directory where live-sync script files are written. Combined with a `script_id`, the caller can locate the corresponding temp file on disk.
+- `script_ids`: Array of script ID strings for all currently subscribed scripts, across all active connections.
+- `success`: Always `true`.
