R0021/2026-03-25/Q006/H3¶
Statement¶
RFC 2119 has been applied in AI-adjacent areas but not specifically to mainstream prompt engineering
Status¶
Current: Supported
Supporting Evidence¶
| Evidence | Summary |
|---|---|
| SRC01-E01 | deliberate.codes blog (2026) applies RFC 2119 to AI coding agent specifications |
| SRC02-E01 | RFC 2119 original standard — designed for interoperability specs, not behavioral constraints |
Contradicting Evidence¶
No direct contradictory evidence.
Reasoning¶
One published blog post (deliberate.codes, Feb 2026) explicitly applies RFC 2119 vocabulary to AI agent specifications. However, this is a practitioner blog post, not a formal standard or academic paper. No major AI vendor, standards body, or academic publication was found applying RFC 2119 to prompt engineering specifically.
Relationship to Other Hypotheses¶
H3 best captures the evidence: RFC 2119 has been applied to AI agent spec-writing (adjacent to prompt engineering) but not to prompt engineering as practiced by the major vendors.
