Apple-Foundation-Models-Agent-Skill

Write, review, or integrate Apple's FoundationModels framework (iOS 26.0+, macOS 26.0+), including WWDC 2026 beta APIs (OSs 27.0+). Use for on-device generation, structured output, tool calling, streaming, prompt attachments, dynamic profiles, agentic orchestration, session properties, Private Cloud Compute, or custom language model providers.

Re-crawls Apple FoundationModels documentation (tutorials/data JSON and Updates page) to refresh symbol-index.md, flag iOS point-release deltas (e.g. 26.5), and list new deprecations. Use after an iOS/Xcode drop or when asked to verify new Foundation Models symbols. Network access required; optional DocC fetch via WebFetch or Sosumi MCP if available.
