Proven skills / Compare

Two design skills · both proven

algorithmic-art vs improve-codebase-architecture

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.”

improve-codebase-architecture

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Brief
“Here is the orders module of a small Express app. ```js // orders.js const db = require("./db"); const stripe = require("stripe")(process.env.STRIPE_KEY); const mailer = require("./mailer"); async function createOrder(req, res) { const { items, couponCode } = req.body; if (!req.user) return res.status(401).end(); let total = 0; for (const i of items) { const p = await db.query("select price, stock from products where id = $1", [i.id]); if (p.rows[0].stock < i.qty) return res.status(409).json({ error: "out of stock" }); total += p.rows[0].price * i.qty; } if (couponCode) { const c = await db.query("select pct, expires from coupons where code = $1", [couponCode]); if (c.rows[0] && new Date(c.rows[0].expires) > new Date()) total = total * (1 - c.rows[0].pct / 100); } const charge = await stripe.paymentIntents.create({ amount: Math.round(total * 100), currency: "usd", customer: req.user.stripeId, confirm: true }); const o = await db.query("insert into orders (user_id, total, status) values ($1, $2, $3) returning id", [req.user.id, total, charge.status]); for (const i of items) await db.query("update products set stock = stock - $1 where id = $2", [i.qty, i.id]); await mailer.send(req.user.email, "Order " + o.rows[0].id, "Thanks! Total: $" + total.toFixed(2)); res.json({ id: o.rows[0].id, total }); } module.exports = { createOrder }; ``` The team keeps breaking checkout when they change coupons or stock rules, and the code is hard to test. Review the architecture and present your findings as a single HTML report: the problems you see, the changes you recommend in order of value, and what the code would look like after the most important change.”
