P5js For Zcl · seyseyseyz bundle P5.js visual composition pipeline with a mandatory 8-10 question visual-brief interview and a post-interview mode choice. Use this skill whenever the user asks for p5.js sketches, creative coding, generative art, interactive canvas animations, shaders, 3D p5 scenes, browser visual prototypes, data visualization, or any p5.js project. After the interview, ask whether the user wants Source Preview Mode (decompose elements, research reusable source/templates, show selectable live previews, then compose a final adjustable sketch) or Direct Generation Mode (skip source/gallery work and generate the final adjustable p5 sketch directly). In both modes, the final HTML must include a parameter panel exposing the useful tunable controls the AI identifies from the algorithm.
