Steam's AI Disclosure Norms and What They Mean for Your Own Dev Team's AI Transparency

Steam's platform-level AI content disclosure requirement — now covering a third of all game releases — offers a genuinely useful reference pattern for engineering teams thinking about how to document and disclose their own AI-generated code and assets internally, not just a gaming-industry curiosity.

Why Internal AI-Code Disclosure Is Worth the Same Rigor

Most engineering teams using AI coding assistants don't have a formal internal practice for tracking which parts of a codebase were substantially AI-generated versus human-written and reviewed — an omission that becomes a real problem during security audits, licensing reviews, or incident investigations, when knowing a specific code path's provenance actually matters.

A Practical Internal Disclosure Pattern, Borrowed From Steam's Approach

• Define your own "materially AI-generated" threshold explicitly, mirroring Apple Music and Steam's approach — a commit with AI-assisted autocomplete doesn't need the same disclosure as a substantially AI-generated module with light human review
• Tag or annotate commits/PRs crossing that threshold at commit time, when the context is fresh, rather than trying to reconstruct provenance later during an audit — retroactive reconstruction is unreliable and expensive
• Extend the same disclosure discipline to AI-generated assets beyond code specifically — documentation, test fixtures, configuration — anywhere "who/what actually created this" could matter later
