If the picture still works without Xiaohei in it, that drawing was wasted.
Xiaohei: A Hand-Drawn Illustration Set for Articles
Added 2026-08-06Note this is a Codex skill, not a Claude one. The style is fixed: pure white ground, thin black hand-drawn line, Chinese annotations handwritten in red, orange and blue, subject at 40 to 60 percent of the frame.
The recurring character is Xiaohei: round head, two dot eyes, no mouth, narrow rectangular body, one orange dot at the chest as the only accent colour. The self-test the author sets is severe — if the picture still works with Xiaohei removed, he was decoration. Eight structural types: workflow, system detail, before-and-after, character state, metaphor, method layers, map route, comic panels. The failure list is written down: figures drawn half the frame tall, and Escher geometry the model over-embellishes unless constrained.
