45
GRADE D
BAND 40–50
Ranked by what each change is worth on the composite — the gap to the next rung of the ladder times the dimension’s weight. Computed from the scores, not written by the model; the model’s sentence under each is the action.
This page should name the product as an IDE for coding agents.
Tie a specific, measurable product outcome to the main offering (e.g., time saved or speed).
Use concrete product nouns and avoid abstract buzzwords in the core claim.
All three together: 45 → 56. Every dimension one rung up: 60 (grade C). Ceiling is 95.
None published. The scorer’s suggestion either reused a word the index strikes (platform, solution, system…) or ran past twelve words, and the gate drops those rather than print them. It will try again at the next re-score.
Five alternative headlines in five angles, a subhead, a call-to-action line, and a line-by-line edit for each of the five dimensions — written only from facts already on codeium.com, gated like a rating (anything with a struck word is dropped, not sold). Delivered on a private page in about a minute.
Five dimensions on one ladder — 5 · 20 · 35 · 50 · 65 · 80 · 95 — weighted clarity 30%, specificity 20%, jargon 20%, proof 15%, call to action 15%. For each: the rung the page matched, the words that drove it, and what would reach the next rung. Full rubric →
The headline phrasing is abstract and does not name a concrete product category.

Next rungThis page should name the product as an IDE for coding agents.
There is a numerical claim about the autograd engine, which is concrete, but overall the page is not focused on a measurable outcome of a product.
Done — a ~50-line autograd engine, written from scratch.
Next rungTie a specific, measurable product outcome to the main offering (e.g., time saved or speed).
Uses multiple abstract terms in surrounding copy (e.g., platform, agents) relative to the headline.

The band 40–50 is where a re-score of this unchanged page would most likely land: on 42 dry re-scores (12 Oct 2026) the median move was 6 points and one in four moved more than 10. A grade only changes when a new score clears the boundary by 5.
No word in the headline itself was judged empty, yet jargon-free scores 65: the scorer found generic phrasing further down the page. Uses multiple abstract terms in surrounding copy (e.g., platform, agents) relative to the headline.
Badges are issued to grades A and B. The share card for this page shows the headline with its jargon struck through; paste the URL anywhere that unfurls links.
