Design vs Testing · both proven

algorithmic-art vs receiving-code-review

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

algorithmic-art

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

Brief: “Make a generative art piece called Tidewater: a single HTML page with a full-window canvas that draws slow, layered flow-field lines in a deep sea palette, seeded so the same seed always gives the same picture. Include a small control panel to change the seed, the line density and the palette, and a button to save the current frame as a PNG. Use p5.js from a CDN.”

receiving-code-review

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Brief: “I received this code review on my pull request that adds caching to our product API. Decide what to do with each comment and present your responses and planned changes as a single HTML page. 1. "Cache TTL of 24h is too long, prices change during the day." 2. "Use Redis instead of the in-memory Map so all 4 instances share the cache." 3. "Rename getProd to getProduct." 4. "You should rewrite this whole module in TypeScript." 5. "The cache key ignores the currency query param, so EUR users can get USD prices." 6. "Add a test."”
