# Apple Expands Siri AI Capabilities with New Tools and Skills Apple Intelligence updates allow developers to integrate complex, multi-step actions directly into Siri. - **Source:** [MacStories](https://brifing.si/source/2d6fb241-7483-4085-bcc6-8301b013a2d2) - **Published:** 2026-11-06 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/e88daf1b-280b-4e64-a695-21bab029940d ## Expanding Siri AI Functionality Apple is significantly broadening the actions available to Siri by moving beyond tightly defined domains. While current natural-language abilities are restricted to calendar, reminders, and messages, the new framework allows developers wider latitude. This shift aims to make Siri more responsive to diverse user requests by loosening previous schema-based constraints. ## Transitioning to Tool-Based Access Developers can now mark App Intents as tools, enabling Siri to access them directly during natural-language requests. This replaces the traditional reliance on App Shortcuts, which required specific phrases naming the app. This mechanism functions similarly to how MCP interacts with models like Codex, streamlining the integration process for third-party applications. ## Technical Constraints and Processing The new tool-based system includes specific operational limits for developers. Each application is restricted to a maximum of 40 tools to ensure performance stability. Furthermore, Apple confirmed that these requests will be processed using Private Cloud Compute, maintaining the company's focus on user privacy while executing complex, external AI-driven tasks. ## Introducing Multi-Step Skills Skills represent a new method for handling complex, multi-step actions that can chain up to 32 tool calls. These are defined as Markdown instructions with YAML front matter, providing clear guidance on how Siri should handle specific user requests. This structure allows for more sophisticated automation compared to simple, single-intent commands. ## Developer Support in Xcode The latest Xcode 27.3 beta includes specialized coding-agent skills designed to assist developers. These tools help engineers implement Siri support within their applications and facilitate rigorous testing of new integrations. By providing these resources, Apple aims to simplify the adoption of the new AI framework before the public software release. ## Customizing Information Snippets Beginning with iOS 27.3, developers will gain the ability to customize the visual presentation of information snippets from their apps. This feature allows third-party content to mirror the appearance of Apple’s own native app data within the Siri interface, creating a more cohesive and professional user experience across the entire ecosystem. ## Timeline for App Store While the iOS 27.3 update is expected to ship in January, the new tools and skills will be available for App Store deployment in the spring. This staggered rollout gives developers time to refine their implementations using the beta tools before the features become accessible to the broader public user base. ## Strategic Shift in Automation By adopting a tool-and-skill architecture, Apple is evolving Siri from a rigid assistant into a flexible agent capable of chaining complex operations. This move aligns Siri with modern AI development trends, potentially increasing the utility of third-party apps by allowing them to participate directly in the system-wide natural language processing environment. ## Sources covering this story - https://www.macstories.net/stories/notes-from-apples-siri-ai-labs-schemas-tools-and-skills/ — --- _Summary written by Brifing from the original reporting.
