Internal Anthropic Claude files found in Apple Support app

Researcher Aaron Perris flagged CLAUDE.md files packaged inside an Apple Support app update on X. The files, part of Anthropic’s Claude Code tooling, appeared in a public build.

CLAUDE.md files are configuration documents that Claude Code reads at the start of each session. They set coding standards, record architecture decisions, list preferred libraries and include review checklists.

One file describes a chat module that combines an AI named Juno with live human agents. It defines three participant roles for message routing – client, agent and assistant – and references conditional compilation flags such as JUNO_ENABLED and DEV_BUILD. The document includes a link to an internal Apple bug-tracker entry.

A second file documents SAComponents, a shared user-interface library that supports multiple Apple platforms, including visionOS. The file separates UI from business logic and notes support for both SwiftUI and UIKit.

Files of this type normally live in source repositories and are not meant to ship in production apps. Their presence in a shipped build may result from a packaging error during release or reflect use of Claude tools in internal development workflows. The files do not by themselves reveal how widely Claude is used at Apple or whether user data was affected.

Apple added support for Claude Sonnet 4 in Xcode 26 in September 2025 and expanded Xcode integration in February 2026 with a native connection to the Claude Agent SDK. Apple has not provided a public comment on the discovery.
