Query	Q006

Query as Received

Has RFC 2119 requirement language (MUST, MUST NOT, SHOULD, MAY) been applied to AI prompt design or AI system behavioral specifications in any published work?

Query as Clarified

• Subject: Use of RFC 2119 keywords in AI prompt design or AI behavioral specifications
• Scope: Published works (papers, standards, blog posts, specifications) that explicitly use RFC 2119 language for AI/LLM prompting or behavioral constraints
• Evidence basis: Academic papers, technical specifications, blog posts, standards documents

Ambiguities Identified

1. "Applied to" could mean formally referenced (citing RFC 2119) or informally using the same keywords. This research focuses on explicit RFC 2119 references or deliberate use of requirement language.
2. "Published work" includes academic papers, blog posts, and open-source documentation.
3. The query does not distinguish between applying RFC 2119 to prompt design specifically vs. AI system specifications broadly.

Sub-Questions

1. Has any published standard or specification applied RFC 2119 to AI prompt design?
2. Has any academic paper used RFC 2119 language for AI behavioral specifications?
3. Has any practitioner or blog post demonstrated RFC 2119 language in prompt design?
4. Are there AI-adjacent standards (like AI safety) that use RFC 2119?

Hypotheses

ID	Hypothesis	Description
H1	RFC 2119 has been formally applied to AI prompt design	Published standards or academic papers explicitly use RFC 2119 for prompt engineering specifications
H2	RFC 2119 has not been applied to AI prompt design	No published work applies RFC 2119 requirement language to AI prompting or behavioral specs
H3	RFC 2119 has been applied in adjacent areas but not specifically to prompt design	The language appears in AI system specifications or behavioral constraints but not in prompt engineering specifically
