think-five-whys skillA

think-five-whys is agent-read markdown (skill) from product-on-purpose/thinking-framework-skills: Runs a Five Whys root-cause trace caveat-first. It leads with the weak evidence (Card 2017 found the single-chain method oversimplifies multi-causal problems), then forces the discipline a bare why-chain lacks, namely flagging at each step whether more than one cause could apply. Use only when Five Whys is asked for by name; for any problem that might have more than one cause prefer think-issue-tree..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
