Validates that all TypeSpec route operations in the AI Foundry data-plane (Foundry) domain have documentation comments and @summary decorators with correct voice, replaces documentation-required suppressions with generated documentation, and uses description override extensions when TypeSpec would concatenate noisy descriptions. USE FOR: reviewing or authoring routes.tsp and routes.generated.tsp files under specification/ai-foundry/data-plane/Foundry/src/, including nested OpenAI routes under src/openai/. DO NOT USE FOR: files outside the Foundry data-plane area, model-only .tsp files, or SDK client customization files (client.tsp).
