Feature & Specification Comparison
Tools & Capabilities Breakdown
Uxgen Tools (9)
uxgen_brief
CALL THIS FIRST for any page or site you are about to build, before writing a single line. It takes the user's own sentence and returns (a) the full text of the design law, (b) the CONTRACT for that trade — what has to be present, and the objection each presence kills, (c) the commerce-kit verdict, which DECIDES which mechanics apply given the nature of the object, (d) the proposed theme, (e) the seven-step path. 🚨 IT RETURNS NO PAGE PLAN AND NO BLOCK IDS, deliberately: a default plan once produced the same page for five unrelated trades. Structure, composition and the graphic gesture are YOURS; the page is written by hand. Calling this tool after you have started coding is good for one thing only: surveying the damage.
uxgen_theme
THE LOCKED GRAMMAR — call it right after `uxgen_brief` and BEFORE the first tag. Its CSS is pasted as is at the top of the page and is not retouched: that is what stops two dark grounds stacking.
🛒 THE COMMERCE KIT. Pass `commerce` and the kit is BUILT and its contract reported. Pass `kit: true` as well and its two files come back IN THIS RESPONSE — `uxgen-commerce.js` and `uxgen-commerce.css`, with the relative path to write each one to. YOU write them; nothing is written here. The kit holds the buying path BY CONSTRUCTION (cart, drawer, quantity, total, free-shipping threshold, delivery date, a button that carries its amount) — it is the answer to a `uxgen_audit` that refused the transaction.
⚠️ MEASURED 25/08: 400 KB — 333 KB of JS and 66 KB of CSS, roughly 100 000 tokens. That is why it is behind a flag and not returned by default. Ask for it ONCE, when you are ready to write the files; do not ask for it to "have a look".
Turns a brand color and an adjective into a COMPLETE set of CSS variables: palette (3 roles + 2 derived), font pair, radii, shadows, rhythm, motion. Works in OKLCH, holds WCAG contrast, and corrects luminance when a pair fails. CALL IT RIGHT AFTER uxgen_brief AND BEFORE THE FIRST TAG, then run it again as soon as the client gives their real color. Its CSS is pasted AS IS at the top of the page and never touched up: that is what stops two dark grounds from stacking. ⚠️ YOU MUST PASS "color" OR "paletteId": "adjective" alone is REFUSED.
