Apple Support app v5.13 accidentally included Claude.md
Preliminary Why: 1 report: 36Kr · subject to change · 1 independent report
Status: no action reported
No source states: loss or records, agent tool, could do, deployer, industry.
Severity minor: Test: contained to one deployer, routine cleanup, no third party touched. Fact: Apple recalled the update within 24 hours; no third-party effect is stated.
Apple's Apple Support app, version v5.13, was pushed as an update on May 1 and unexpectedly included a Claude.md file. The source describes such a file as one that tells an AI what a project is, how to build it, and what to avoid, and says Apple uses Claude Code internally to build production-level applications. The file exposed the app's dialogue architecture, in which an automatic AI backend and human agents switch through a protocol layer. Aaron Perris, an analyst at MacRumors, discovered it. Apple recalled the update within 24 hours, but some content was already exposed. The source says the file itself contained no secrets, and it raises questions about how AI-written code reached a release package despite review.
