rfc 2119 guidance Shipped
What this lens looks for
Group the guidance under clear headings and write each rule with the correct RFC 2119 keyword: MUST only for what genuinely breaks, SHOULD for strong recommendations, MAY for options. Each rule must be specific and checkable — no platitudes. Lead the guideline with a summary statement a reader can act on without reading further.
What its verifier checks
Each rule uses an RFC 2119 keyword per its exact meaning; MUST is reserved for breaking concerns; every rule is specific and checkable; a 1-3 sentence actionable summary opens the guideline.
