Proven skills / Compare

Two design skills · both proven

improve-codebase-architecture vs theme-factory

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.

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.”

“Build the one-page invitation site for the Harvest Table, a community garden's autumn dinner: a hero with the date and place, the story of the garden, the menu by course, the people cooking, a map drawn in inline SVG, and an RSVP form with success and error states. Make it feel warm and finished.”
