foundation-models-utilities

Use this skill when building a Swift package that adapts a server-side language model to Apple's Foundation Models framework so it can be used with `LanguageModelSession`. Triggered when the user asks to "build a Foundation Models LanguageModel", "implement the LanguageModel protocol", "wrap our inference API for Foundation Models", "create a server model package for Apple", or works on a `*LanguageModel.swift` / `*Executor.swift` file that conforms to `LanguageModel` / `LanguageModelExecutor`.

Use this skill when working with the `FoundationModelsUtilities` Swift package — a collection of utilities that extend Apple's Foundation Models framework with a chat completions client, on-demand "skills" that activate via tool calls, and history-management modifiers (drop completed tool calls, rolling window, summarization). Triggered when the user asks to "talk to a chat completions endpoint", "connect to OpenAI / a local LLM server", "add skills to a session", "manage transcript size", "summarize history", "drop tool calls", "rolling window", or works in a file that imports `FoundationModelsUtilities`.
