R0028/2026-03-26/C011¶
Claim: RFC 2119 has been applied to AI prompt design exactly once, in a single practitioner blog post from February 2026.
BLUF: 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.
Probability: Unlikely (20-45%) | Confidence: Low
Correction needed: The blog post applies RFC 2119 to specifications for AI coding agents, not directly to 'AI prompt design.' The claim that it has been applied 'exactly once' is unfalsifiable without exhaustive search of all published content.
