Comment (by schmitzoide):

 First off, this is a fantastic proposal. Having a provider-agnostic AI
 foundation in Core is exactly what the ecosystem needs — it will reduce
 fragmentation and give plugin developers a stable base to build on. Really
 excited to see this moving forward.

 That said, I wanted to raise one potential design consideration regarding
 how WP AI Client might interact with the Abilities API.

 == The Question ==

 If WP AI Client registers abilities like `ai/prompt` or `ai/completion`,
 could this create some philosophical tension?

  1. '''Layer confusion''' - Abilities typically represent "what WordPress
 can do". An ability to "call an AI model" feels more like external
 infrastructure that WordPress //uses//.

  2. '''Meta-recursion''' - The API was designed for AI to orchestrate
 WordPress. Having "invoke AI" as a discoverable ability could create
 circular confusion — a bit like listing "call the chef" as a menu item.

  3. '''Schema considerations''' - Abilities have deterministic schemas. AI
 responses are non-deterministic.

  4. '''Discovery implications''' - Plugins that auto-discover abilities
 might inadvertently expose "call external LLM" as a tool — confusing UX.

 == Possible Solutions ==

  * '''Option A:''' `is_infrastructure` metadata flag for filtering
  * '''Option B:''' Namespace convention (`ai/*` for internal use)
  * '''Option C:''' Keep WP AI Client as developer infrastructure without
 Abilities exposure

 Again, great work on this proposal. Just wanted to flag this early in case
 it's helpful for the design. Happy to discuss further!
