five whys Shipped
What this lens looks for
Apply the five-whys technique as specified in the framing-techniques guideline (agenticdevelopercookbook://guidelines/brainstorming/framing-techniques). Ask "Why?" iteratively, targeting each answer rather than the original statement, until a root cause is reached. Requirements: five-whys-before-generating, five-whys-chain, five-whys-stop.
What its verifier checks
Frame phase. Invoke when the seed sounds like a solution ("I want to build X") — apply Five Whys to surface the underlying need before generating. See the framing-techniques guideline.
