+.SYNOPSIS
+    Evaluates tool and prompt descriptions and produces a Markdown results report using Tool Description Evaluator from Mcp repo.
+
+.DESCRIPTION
+    This script builds and runs the ToolDescriptionEvaluator (.NET) against a set of tool and prompt definitions.
+    It restores and compiles the evaluator, executes it with the provided JSON inputs, and emits a `results.md`
+    report. The script supports configuration via parameters and environment variables for the embedding model
+    service used during evaluation.
+
+.LINK
+    https://github.com/microsoft/mcp/tree/main/eng/tools/ToolDescriptionEvaluator
+
+.PARAMETER EvaluatorPath
+    The path to the evaluator project root (or its `src` directory) that will be restored, built, and executed.
+
+.PARAMETER ToolsFilePath
+    The path to the JSON file containing tool definitions to be evaluated.
+
+.PARAMETER PromptsFilePath
+    The path to the JSON file containing prompt definitions to be evaluated.
+
+.PARAMETER OutputFilePath
+    The target file path where the generated `results.md` will be moved after the evaluator runs.
+
+.PARAMETER AoaiEndpoint
+    The full endpoint URL for the embedding model (e.g., Azure OpenAI embeddings) used by the evaluator.
+
+.PARAMETER TextEmbeddingApiKey
+    The API key used to authenticate with the embedding endpoint. Prefer providing this via a secure
+    secret store or environment variable rather than hard-coding.
+
+.NOTES
+    - The evaluator emits `results.md` in the evaluator folder; this script moves it to `OutputFilePath`.
+    - Requires .NET SDK available on PATH.
+    - Set-StrictMode is enabled.
+
+.EXAMPLE
+    .\Invoke-ToolDescriptionEvaluator.ps1 `
+    -EvaluatorPath "C:\work\mcp\eng\tools\ToolDescriptionEvaluator\src" `
+    -ToolsFilePath "C:\work\azure-sdk-tools\tools\azsdk-cli\azure-sdk-tools.json" `
+    -PromptsFilePath "C:\work\azure-sdk-tools\tools\azsdk-cli\azure-sdk-prompts.json" `
+    -OutputFilePath "C:\work\azure-sdk-tools\tools\azsdk-cli" `
+    -AoaiEndpoint "https://<your-endpoint>/openai/deployments/text-embedding-3-large/embeddings?api-version=2023-05-15" `
+    -TextEmbeddingApiKey (Get-Secret -Name 'TextEmbeddingApiKey')
+
+    Runs the evaluator with the specified tools and prompts files, then moves the generated results to the output path.
