C011 — Claim Definition¶


Research	R0028 — Prompt Engineering Claims
Run	2026-03-26
Claim	C011

Claim as Received¶

RFC 2119 has been applied to AI prompt design exactly once, in a single practitioner blog post from February 2026.

Claim as Clarified¶

Partially correct. A blog post from deliberate.codes dated February 1, 2026 does apply RFC 2119 keywords to writing specifications for AI coding agents. However, the claim that this is the only such application is difficult to prove (proving a negative), and the post applies RFC 2119 to software specifications for AI agents rather than directly to prompt design.
