Two design skills · both proven

algorithmic-art vs crypto-protocol-diagram

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.

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.”

crypto-protocol-diagram

Extracts protocol message flow from source code, RFCs, academic papers, pseudocode, informal prose, ProVerif (.pv), or Tamarin (.spthy) models and generates Mermaid sequenceDiagrams with cryptographic annotations. Use when diagramming a crypto protocol, visualizing a handshake or key exchange flow, extracting message flow from a spec or RFC, diagramming a ProVerif or Tamarin model, or drawing…

Brief: “Draw the message flow of this login protocol as a single HTML page with an SVG sequence diagram, and note any weaknesses. 1. Client sends username to server. 2. Server replies with a random 16-byte nonce and the user's salt. 3. Client computes H = SHA-256(salt || password) and sends HMAC-SHA256(key=H, msg=nonce). 4. Server looks up stored H, computes the same HMAC and compares. 5. On success the server returns a session token valid for 30 days.”
